The findings carry particular weight because they demonstrate that earlier underwater discoveries at Murujuga, first reported by the Deep History of Sea Country project in 2020 and again in 2023, were not isolated anomalies. Instead, they form part of a broader submerged cultural landscape spread across a region now inscribed on the World Heritage list. For archaeologists studying the deep history of the Australian continent, this distinction between a single lucky find and an extensive, patterned distribution of cultural material is fundamental. It means the seabed around Murujuga can be studied systematically, with sites predicted, located and interpreted in relation to one another, much as terrestrial landscapes are.

The scale of what was lost to the sea is difficult to overstate. More than two million square kilometres of Australia’s continental shelf was submerged as sea levels rose following the end of the last Ice Age, a process that unfolded over thousands of years as ice sheets melted and ocean basins filled. Before that transformation, generations of First Nations peoples lived across landscapes that now lie beneath the ocean, including coastal plains, river valleys and freshwater springs that would have made the region attractive for settlement. The newly documented sites offer a rare, direct window into that drowned world, capturing two distinct kinds of places within what was once dry, connected land.

The first of these sites centres on an ancient freshwater spring, a feature that would have been nothing short of vital in the arid northwest. Reliable water sources in such environments act as anchors for human activity, drawing people together for drinking, food procurement, social gatherings and ceremony. The presence of stone artefacts associated with the spring is consistent with such a pattern of congregation, indicating that this spot on the now-submerged plain was a focal point in the lives of the people who used it. The second site tells a different story: it is associated with a rocky hill overlooking an ancient river channel, a vantage point that would have offered both practical advantages and a different set of resources. Together, the two sites show how people used different parts of the landscape when the archipelago was still connected by dry land, moving between springs, hills and watercourses in ways that structured their daily and seasonal lives.

Among the most technically significant results of the analysis is evidence of raw material selection and transport. Some of the artefacts were made from stone sourced from around Rosemary Island, approximately 23 kilometres from where they were ultimately found on the seabed. That distance matters. It suggests that people deliberately moved valuable stone resources across a landscape that is now entirely underwater, carrying preferred raw materials over considerable distances either for immediate use or as part of broader exchange and mobility patterns. In archaeological terms, such transport demonstrates decision-making about stone quality, availability and curation, and it provides a measurable link between distinct places within the drowned landscape, effectively reconstructing ancient connections that no land-based survey could ever recover.

The research is the product of a partnership between underwater archaeology researchers from Flinders University, The University of Western Australia, James Cook University and the University of York in the United Kingdom, working with the Murujuga Aboriginal Corporation and its Rangers. Crucially, the collaboration was not a token consultation. Rangers from the Murujuga Aboriginal Corporation Land and Sea Unit trained as scientific divers and worked alongside the archaeologists to locate and document the underwater cultural sites. Malik Churnside and Richard Variakojis, Rangers from the Land and Sea Unit and co-authors on the paper, undertook scientific diver surveys and made some of the underwater discoveries themselves, embedding Indigenous expertise and custodianship directly into the scientific process.

Lead researcher Professor Jonathan Benjamin, a specialist in marine archaeology at Flinders University’s College of Human Sciences and Culture, emphasised the value of working beside trained Indigenous Rangers who actively contributed to this challenging scientific research. Underwater survey in this environment is far from straightforward: visibility, currents, tides and the sheer difficulty of recognising cultural material on a seabed that has been reshaped by thousands of years of marine processes all combine to make such work demanding. Recognising a stone artefact amid natural rock, and distinguishing a deliberate human deposit from geological scatter, requires both archaeological training and an intimate understanding of the country in question, which is precisely what the partnership model provides.

For the Ngarda-Ngarli people, the Traditional Owners of the region, the findings confirm an understanding of Country that has never been confined to what is above the waterline. Vincent Adams, Director of the Murujuga Aboriginal Corporation, noted that the Ngarda-Ngarli people have cared for Murujuga for at least 50,000 years, and that the research shows their cultural landscape extends far beyond the shoreline and into Sea Country, where important parts of their story remain preserved beneath the sea. In Aboriginal and Torres Strait Islander frameworks, Sea Country is not an empty marine space but a living part of Country, holding ancestral connections, responsibilities and knowledge. The archaeological evidence now aligns with that understanding in a form recognised by mainstream science.

Adams also pointed to the implications of the region’s World Heritage recognition, observing that it brings new responsibilities as well as global recognition, and that research of this kind strengthens the community’s ability to identify, understand and protect the whole Murujuga cultural landscape, including Country that was submerged when sea levels rose thousands of years ago. That protective dimension is significant. Submerged heritage is vulnerable to industrial activity, anchoring, dredging and other seabed disturbances, and it is far less visible, and far less legally established, than terrestrial archaeology. Documented sites, mapped distributions and published evidence give custodians and regulators a concrete basis for managing what lies beneath the water with the same seriousness applied to heritage on land.

The study, an observational study published in Quaternary Science Reviews under the DOI 10.1016/j.quascirev.2026.110307, builds on the landmark discoveries reported in 2020 and 2023 by the Deep History of Sea Country project team, and its authors are affiliated with the ARC Centre of Excellence for Indigenous and Environmental Histories and Futures. The authors declare no known competing financial interests or personal relationships that could have appeared to influence the work. Taken together, the discoveries reframe the drowned continental shelf not as a void between archaeological sites but as an integral, preserved component of Australia’s deep human history, one in which freshwater springs, rocky hills and transported stone record the movements and decisions of people whose world the ocean swallowed at least 9,000 years ago, and whose descendants continue to read that story from beneath the waves.

The methodology behind the study is straightforward but rigorous. The authors searched Scopus, the multidisciplinary citation database launched by Elsevier in 2004, using keywords such as climate change, paleoclimate, Holocene, climate variability and Quaternary, combined with Boolean operators and explicit inclusion and exclusion criteria. After removing duplicates and screening titles and abstracts for relevance, they retained 1,141 articles published across the 22-year window. The dataset was then analyzed and visualized with VOSviewer, the bibliometric mapping software developed at Leiden University’s Centre for Science and Technology Studies, alongside Microsoft Excel. This allowed the team to track annual publication trends, identify the most productive countries, institutions and authors, map keyword co-occurrences, and construct citation networks linking the field’s core journals. The authors are careful to note that their findings depend entirely on the coverage, accuracy and classification practices of Scopus itself, a caveat that shapes how the results should be read.

The temporal trends reveal a field in sustained expansion, though not without turbulence. In 2002, the earliest year of the analysis, only 26 documents appeared in the search results. Output climbed irregularly thereafter, with a sharp jump between 2012 and 2013, when the count leapt from 42 to 73 papers, and another surge between 2016 and 2018, culminating in a peak of 84 publications in 2018. The trajectory was not monotonic: 2014 saw a steep fall back to 42 documents, and 2022 dropped to 58 after hovering between 65 and 73 in the preceding years, before recovering slightly to 68 in 2023. These oscillations, the authors suggest, may reflect irregularities in publication patterns or in how the database collects and indexes records. The overall message, however, is unambiguous: scientific interest in Holocene climate variability has grown substantially over the long term, mirroring broader concern about understanding natural climate baseline conditions against which modern anthropogenic warming can be compared.

The geography of the field is strikingly lopsided. The United States leads with more than 300 publications, followed by Germany with roughly 250 and the United Kingdom with around 225. China ranks fourth with approximately 175 papers, and France contributes about 150. Canada, Australia, Spain, Switzerland and Sweden round out the top ten, each producing between 75 and 125 documents. At the institutional level, the Chinese Academy of Sciences stands out as the single most prolific affiliation, exceeding 100 papers, with France’s CNRS close behind. The University of Bern in Switzerland, Spain’s Consejo Superior de Investigaciones Científicas and Germany’s Alfred-Wegener-Institut Helmholtz-Zentrum occupy an intermediate tier, while Lanzhou University, the Deutsches GeoForschungsZentrum GFZ, China’s Ministry of Education and the University of Minnesota Twin Cities contribute more modest volumes. The map that emerges is one of dense research capability in North America, Western Europe and China, and comparatively thin coverage elsewhere.

Individual researchers show similarly uneven productivity. Melanie J. Leng tops the author ranking with around 18 papers in the dataset, well ahead of R. Lawrence Edwards at roughly 10. Achim Brauer, Hai Cheng and Feng Sheng Hu each published between six and eight papers, while most other highly ranked authors produced fewer than five. In the journal landscape, Quaternary Science Reviews dominates both in output and influence, typically publishing between 5 and 15 relevant papers per year and reaching approximately 15 in 2023. The Holocene follows a fluctuating path of 3 to 10 papers annually, Quaternary International varies between 2 and 8 with growth after 2010, and Palaeogeography, Palaeoclimatology, Palaeoecology records 2 to 7 per year. The Journal of Quaternary Science trails with 1 to 3. Citation network analysis confirms Quaternary Science Reviews as the most influential source, followed by Quaternary International, with related outlets such as Climate of the Past, the Journal of Paleolimnology and Marine Geology anchoring the multidisciplinary edges of the network.

Perhaps the most revealing finding concerns disciplinary breadth. Earth and Planetary Sciences accounted for about 37.7 percent of the publications, the largest single share, but the remainder is scattered across a remarkable range of fields: Environmental Sciences at 18.4 percent, Agricultural and Biological Sciences at 15.9 percent, and Arts and Humanities at nearly the same 15.8 percent, with Social Sciences contributing 8.1 percent. Medicine, chemistry and energy each registered only fractions of a percent. Keyword density mapping reinforces this picture of interdisciplinarity. The word Holocene dominates the center of the co-occurrence network, surrounded by clusters referencing paleoenvironment, precipitation, monsoon and glaciology, alongside oceanographic and isotopic terms such as Atlantic Ocean, oxygen isotope and sea surface temperature. Palynological and sedimentary vocabulary, including lacustrine deposit, pollen and fire history, appears prominently, and terms like genetics, mitochondrial DNA and genetic variability hint at links to biological evolution and species adaptation. Holocene climate research, in other words, is not the province of climatologists alone but a genuinely hybrid enterprise spanning geology, ecology, archaeology and even the humanities.

The study contextualizes this bibliometric portrait within the scientific substance of the field. Holocene climate variability has been reconstructed from a diverse suite of paleoclimate archives, each with distinct strengths. Ice cores from polar regions deliver annual-resolution records of oxygen isotopes with precise dating; speleothems from caves capture seasonal-scale signals in isotope ratios and trace elements; marine sediment cores, rich in foraminiferal assemblages and magnesium-to-calcium ratios, offer centennial-scale resolution with moderate dating accuracy. Pollen assemblages document past vegetation and hydroclimate, charcoal reflects fire activity, and stable isotopes such as δ18O and δ13C are widely used to infer temperature, precipitation sources and moisture balance. The driving mechanisms span multiple timescales: slow orbital forcing from Milankovitch cycles shaped the early to mid-Holocene climatic optimum, while solar variability, volcanic eruptions and internal ocean-atmosphere dynamics, including the Atlantic Meridional Overturning Circulation, the North Atlantic Oscillation and the El Niño-Southern Oscillation, generated abrupt and regionally heterogeneous responses such as the 8.2 ka cooling event. Transient model simulations from the Paleoclimate Modelling Intercomparison Project broadly reproduce orbitally driven trends, though discrepancies persist in the magnitude and timing of regional hydroclimatic shifts, particularly in the tropics and Southern Hemisphere.

The bibliometric data also expose structural weaknesses that the authors argue the field must confront. Regional disparities are pronounced: Europe, North America and China dominate the literature, while Africa and South America remain markedly underrepresented, a gap that echoes the spatial bias already known in proxy data coverage itself. Temporal resolution varies enormously across archives, from annually layered tree rings and ice cores to coarser marine sediments, complicating direct comparison of short-lived climatic events. Chronological uncertainties arising from radiocarbon calibration and reservoir effects further limit the precision of regional syntheses, and proxy sensitivity can differ depending on local environmental conditions. The authors also flag the limitations of their own approach, noting that English-language dominance in the indexed literature, keyword selection and Scopus’s disciplinary classifications all introduce potential biases into the analysis. They call for stronger integration of climate models with high-resolution proxy data, improved dating techniques, and expanded interdisciplinary and global collaboration to fill the geographic and methodological gaps.

Why does this matter beyond the census-taking? Because the Holocene is the stage on which human civilization developed, and its climate history provides the natural baseline against which modern, human-driven warming must be judged. Since the Industrial Revolution, emissions of carbon dioxide and methane have intensified the greenhouse effect to a degree that now overwhelms the natural forcings, orbital, solar and volcanic, that governed Holocene variability for millennia. Understanding how climate behaved under purely natural conditions, and how societies responded to events like the African Humid Period’s abrupt termination or the sapropel S1 interval in the eastern Mediterranean, informs climate resilience strategies, resource management and policy development. The authors expect research on the topic to keep growing in the coming years, and their analysis suggests where that growth is most needed: in the under-sampled regions of the global South, in the integration of models with proxy records, and in the high-resolution chronologies that would let paleoclimatologists pin down exactly when and how fast past climates changed. A field that can map its own blind spots, this study shows, is far better equipped to close them.

The central finding is staggering in its implications for how prehistoric life is understood in the region. Land once roamed by hunter-gatherers and later tended by early farmers now lies deep beneath the sea. The present-day Venice Lagoon, famous for its island city built on marshy, muddy ground, was once dry land that lay kilometres from the coast. The same is true of other towns in the lagoons further east, such as Grado, and even present-day coastal cities like Trieste would once have stood in hills overlooking swamps and lagoons below. In other words, some of the most archaeologically significant terrain in the region is invisible to conventional, land-based survey, hidden beneath seabed sediments that have accumulated over millennia.

Technically, the study is a palaeolandscape reconstruction built from two complementary strands of evidence. The researchers combined existing data from the analysis of sediment cores with new, high-resolution geophysical data acquired by OGS. Sediment cores allow scientists to identify different types of deposits, each characteristic of a particular environment, whether open marine, coastal barrier, lagoon, marsh or floodplain. Geophysical surveys, in turn, reveal the buried architecture of these deposits across wide areas of the seabed. By identifying the sediment types and modelling successive flooding episodes, the team was able to trace the backward shifting of coastal barriers, deposits running parallel to the shore, and the back-barrier systems, the marshy areas that lay beyond them. The result is a sequence of maps showing how the coastline retreated inland, stage by stage, across five millennia.

The timeline that emerges is anything but smooth. The reconstruction identifies a rapid rise in sea level around 8,400 BC that created tidal channels, marshes, sandbanks and large lagoons, followed by a more stable phase in which these features could persist and develop. Then came a large rise, a total of eight metres in the 1,200 years leading up to 6,600 BC, during which the sea repeatedly created, subsumed and recreated lagoons and marshes, pushing kilometres inland. A further major rise of up to five metres after 6,000 BC again shifted coastal features landward. Finally, after about 5,800 BC, the origins of the lagoons and the landscape recognisable today began to form. At times, the rate of rise reached up to 25 millimetres per year, a pace that would have been plainly visible within a single human lifetime.

That pace matters for understanding what prehistoric communities actually experienced. A rise of 25 millimetres per year translates into roughly a metre of relative sea level change across two or three generations, enough to permanently abandon settlements, alter hunting grounds and redraw the geography of trade and movement. The study highlights the constantly changing environment that Mesolithic hunter-gatherers had to cope with, as rising water altered habitats, resources and the availability of food such as plants, fish and animal prey. Coastal barriers were overrun and rebuilt; lagoons formed, filled and re-formed. Successive shaping and reshaping of coastal features influenced the lives of Mesolithic and Neolithic people and the development of local communities, as the sea swallowed features it had previously formed, shaped new ones, and eventually produced the origins of the modern coast.

Samuele Ongaro, lead author and PhD researcher at the University of Southampton, an archaeologist by training, emphasises why these drowned terrains matter. Submerged landscapes, he notes, are an important missing piece in the study of prehistory, especially in the Northern Adriatic, because they hold many secrets about how ancestors lived and how they were connected to the land. According to Ongaro, the results of the research allow the reconstruction of these lost landscapes, the environments they hosted, how they changed over time, and what significance they might have held for prehistoric populations, which he describes as a fundamental step for future archaeological research in the area. The framing is significant: rather than treating the seabed as a blank between terrestrial sites, the study treats it as a continuous, inhabited landscape worthy of systematic investigation.

The environmental variety of the reconstructed coast also helps explain why people were drawn to it in the first place. As Ongaro points out, the variety of coastal environments, lagoons, river deltas, marshes and swamps, would have been an attractive landscape for foragers and hunters, offering diverse and productive ecological niches. Yet the flat nature of the landscape also made it prone to significant land loss, and communities were forced to adapt over time, choosing where to hunt, fish and settle. This tension, between ecological richness and geographic vulnerability, is central to the study’s archaeological implications. The team hopes further study will reveal more about how communities shifted their activities in response to coastal flooding, and how this eventually affected the advent of farming in the region by Neolithic people, one of the most debated transitions in European prehistory.

From the marine geoscience side, the collaboration demonstrates the value of integrating geological and geophysical data. Dr Federica Donda, a marine geologist from the Geophysics section of OGS and co-author of the paper, comments that the study shows how integrating geological and geophysical data makes it possible to reconstruct the environmental evolution of areas that are now submerged, while highlighting that the seabed is an integral part of archaeological heritage. In her view, a significant portion of the areas frequented by ancient populations is now underwater, and their history and evolution cannot be understood through terrestrial archaeology alone. This is a pointed methodological claim: any model of Mesolithic or Neolithic settlement in the Northern Adriatic that ignores the drowned plains is, by definition, incomplete, because it excludes the very terrain where much of early coastal life unfolded.

The paper, titled Palaeolandscape reconstructions for the Northern Adriatic: Inundation models, depositional environments, and potential archaeological implications, underscores the potential of palaeogeographic reconstructions for studying the evolution of past societies. By returning to archaeological research a piece of territory that is no longer visible today, but which for thousands of years was part of the European landscape, the work opens a path toward predictive models of where submerged prehistoric sites might survive. The method of research is described as computational simulation and modelling, combining inundation models with depositional interpretations, an approach that could be applied to other drowned coastlines around the world where post-glacial sea level rise has erased the record of early coastal adaptation.

For a region whose modern identity is bound up with the fragile balance between water and land, from the Venice Lagoon to the gravelly shores of Trieste, the study offers a deep-time perspective on an ongoing process. The coast that residents and visitors know today is merely the latest configuration in a long sequence of flooding, barrier migration and lagoon formation that began when the last ice age ended. What the Southampton and OGS team has shown is that this sequence is readable in the sediments beneath the seabed, and that within those sediments lie clues to how some of Europe’s earliest coastal communities lived, moved and adapted as the sea rose around them. The next stage of research, the authors suggest, will focus on pinning down how human activity responded to each successive inundation, turning a drowned landscape into a map of prehistoric resilience.

For decades, climate scientists have tended to characterise the last ice age in Australia as a period of relatively simple, less variable rainfall, with the assumption that rainfall patterns became patchier, less reliable and more complex only during the past 12,000 years, the epoch known as the Holocene. That framing has been used to explain changes in human behaviour, flora, fauna and fire regimes, particularly around the transition from the Late Pleistocene into the Holocene. The new analysis suggests that this apparent shift in complexity may not reflect what the climate was actually doing, but rather what the sediment and fossil records are capable of revealing about it.

The study examined 69 natural paleoenvironmental archives from tropical Australia spanning the past 130,000 years. These archives, which include sediments and fossils preserved in lakes, wetlands and other deposits, are among the main pillars of our understanding of how the climate works. Yet the team identified a striking gap in the record: there are no published hydrological records of sub-decadal resolution from the region dating to before 1900 years ago. In other words, the finest-grained evidence about short-term rainfall variability simply does not exist for most of the period in question.

That absence, Dr Wall argues, may have shaped scientific interpretation in a subtle but profound way. Reconstructions from further back in time tend to be of poorer quality, and when lower-resolution records are compared with the higher-resolution archives available for recent millennia, the older past can appear smoother and simpler than it really was. The research team found no support for the previous hypothesis that the Holocene is uniquely hydrologically heterogeneous. Instead, they suggest that the trend of reduced resolution in older records could be mistaken for greater simplicity, creating an illusion of a climate that became more erratic only recently.

“Sediment and fossil records are a main pillar for our understanding of how the climate works – but climate scientists have got something wrong about Australia’s ice age,” says Dr Wall, lead author of the paper. “Experts tend to think of the last ice age as having less complex rainfall patterns than today. Our new research suggests that narrative may have arisen from what the past can’t tell us, rather than what it can.” The distinction is more than academic. Characterising the Holocene as a period of uniquely erratic rainfall has significant implications for interpreting how past human populations and ecosystems responded to climate change, and any interpretation built on that assumption may need to be re-examined.

The terminology of ice ages can be counterintuitive, and Dr Wall is careful to place the findings in their proper temporal frame. “Technically, we’re still in the ice age, just a relatively warm and wet period called an interglacial,” she explains. The Quaternary ice age encompasses both the cold glacial periods and the warmer interludes between them, including the one humanity inhabits now. The last time the Earth was wetter than today was a period from 130,000 to 115,000 years ago, known as the Last Interglacial. That interval is of great interest to climate scientists because it is also the last time the Earth was warmer than today, which makes it a valuable analogue for understanding where a warming world might be headed.

One of the most consequential findings of the study concerns how that Last Interglacial compares with the present. When the team looked at the bigger picture across their 130,000-year window, they found that rainfall during the Last Interglacial and rainfall today look pretty indistinguishable. If the warm, wet conditions of that ancient interval produced rainfall patterns similar to those of the modern era, then the variability and complexity we experience today are not a recent novelty of the Holocene. The same kinds of hydrological behaviour were likely operating more than a hundred millennia ago, even if the surviving archives cannot capture their fine detail.

That conclusion carries an uncomfortable implication for climate forecasting. “Unfortunately, that may mean that a warming climate might be even less predictable than we had assumed,” Dr Wall warns. If past warm periods exhibited rainfall complexity comparable to today’s, then the range of natural hydroclimate behaviour under warming conditions may be broader than models and narratives built on a supposedly simple ice age would suggest. For a continent like Australia, where droughts, floods and fire seasons hinge on rainfall reliability, the predictability of water availability is among the most consequential questions climate science can address.

The methodological lesson the authors draw extends well beyond tropical Australia. “To understand how any region fits into the greater climate system, Quaternary science must be explicit about what can and cannot be determined from the data available,” says Dr Wall. Paleoenvironmental archives are inherently uneven: some periods and places preserve rich, finely layered records, while others yield only coarse snapshots. When scientists compare records of different resolutions without accounting for that difference, they risk mistaking gaps in evidence for gaps in variability. Making those limitations explicit, the study argues, should become standard practice in reconstructions of past hydroclimate.

The research, titled “Hydroclimate complexity across the last glacial cycle in tropical Australia: reassessing the uniqueness of the Holocene”, was conducted by Alexander Wall, Emma Rehn, Haidee Cadd, Vanessa Mailhammer, Will Reynolds, Brian Jones, Zenobia Jacobs, Serayah Steele and Tim Cohen, and has been published in Quaternary Science Reviews. By reassessing 69 archives across a full glacial cycle, the team has opened a new conversation about how complexity is defined and detected in the deep past. The broader message is one of humility toward the archive: the silence of ancient sediments about short-term rainfall swings does not mean those swings were absent, and the climates that shaped Australia’s earliest environments may have been every bit as intricate as the one we live in today.
