Over 100 global climate sensitive rivers are experiencing large and severe changes in streamflow volume and timing
Only about one-third of global rivers (or tributaries) remain in a nearly natural condition, known as climate-sensitive rivers. We lack clear evidence on the changes in streamflow volume and timing of these rivers, which significantly compromises our capacity for protection. Here, we analyse alterations in streamflow and centre of timing at 1017 stream gauges across 812 climate-sensitive rivers and tributaries worldwide from 1950 to 2022. We obse…
The age and paleoclimate implications of relict periglacial block deposits on the New England Tablelands, Australia
Pleistocene periglacial activity in eastern Australia was widespread and has been predicted to have extended along much of the east coast. This paper describes block deposits in the New England Tablelands, Australia, as far north as 30°S. These deposits are characterized by openwork blocks on slopes below the angle of repose. The deposits are positioned where frost cracking was significant and range in area up to 8 ha. Surface exposure dating usi…
Reconstructing Holocene fire records using dune footslope deposits at the Cooloola Sand Mass, Australia
In this study, we assess charcoal records from eolian deposits within the Cooloola Sand Mass, a subtropical coastal dune system in eastern Australia, to determine whether they can be used as a proxy for Holocene fire history. We excavate four profiles in depositional wedges at the base of dune slipfaces (footslope deposits) and calculate charcoal concentrations for three size classes (180–250 μm, 250–355 μm, and 355 μm–2 mm) at predetermined dept…

Holocene evolution of a barrier-spit complex and the interaction of tidal and wave processes, Inskip Peninsula, SE Queensland, Australia
This paper presents a reconstruction of the Holocene evolution of the Inskip Peninsula in SE Queensland. The peninsula links two major dune fields, the Cooloola Sand Mass to the south and K’gari (Fraser Island) to the north. Geomorphic features of this peninsula include remnant parabolic dunes, numerous beach ridges with foredunes, and a series of spits. Together these features provide insight into Holocene coastal evolution and changing marine c…
Combining and competing effects between precipitation and temperature on Holocene fire regime evolution inferred from a sedimentary black carbon record in southwestern China
Wildfires are sensitive to climate change, but their response to changes in temperature and precipitation on long timescales is still disputed. In this study, we present a ~9.4 ka black carbon mass sedimentation rate (BCMSR) record from Lake Ximenglongtan (XMLT), southwestern China, to elucidate the Holocene fire regime and its linkages to climatic conditions. The results indicate that the regional fire activity was low during the early Holocene …
A quantitative temperature reconstruction of the ‘Little Ice Age’ in southern China
We present a branched glycerol dialkyl glycerol tetraethers (brGDGTs)–based mean annual temperature reconstruction covering the last millennium from a subtropical lake in Guangxi Province, southern China (23°N). We demonstrate that the pattern and absolute values of mean annual temperatures reconstructed using the eastern African lake brGDGTs calibration based on the methylation of 5-methyl branched tetraethers index provided the most reliable an…
Stratigraphic and geomorphologic evidence of three MIS 2 glacial advances in the South Fork Hoh River valley, Olympic Mountains, Washington, USA
The geomorphology and stratigraphy of the South Fork Hoh River (SF Hoh), Olympic Mountains, Washington, allow for greater understanding of Marine Oxygen Isotope Stage 2 (MIS 2) ice fluctuations, glacial dynamics, and sedimentation. Age control from optically stimulated luminescence and radiocarbon dating constrains deposited sediments associated with four Late Pleistocene ice-marginal positions that formed under reduced ice volume conditions comp…
Geomorphology of the Inskip Peninsula, Queensland, Australia
The Inskip Peninsula is the link between two major coastal dune fields; Fraser Island (the world’s largest sand island) and the adjacent Cooloola Sand Mass. There has been a notable lack of research into the geomorphology of the sand masses and the relationship between the two dunefields. This paper presents a detailed geomorphological map of the Inskip Peninsula at a scale of 1:10,000. The Peninsula can be divided into three parts; an eastern se…
High-resolution remapping of the coastal dune fields of south east Queensland, Australia
The sand islands and shore-attached dune fields of south east Queensland form the world’s oldest and largest coastal sand dune system. Here we present updated morphological maps for the dune fields based on topographic expression and geomorphic relationships. Individual dunes were delineated using high-resolution elevation data and were grouped into morphosequences based on the elevation, drainage characteristics and slope characteristics of the …
Prehistoric and historic overbank floods in the Luoyang Basin along the Luohe River, middle Yellow River basin, China
Multiple glacial advances in the Rangitata Valley, South Island, New Zealand, imply roles for Southern Hemisphere westerlies and summer insolation in MIS 3 glacial advances
Stratigraphic evidence and extensive optically stimulated luminescence (OSL) geochronology from an 18-km-long reach of the middle Rangitata Valley, South Island, New Zealand, provide evidence for at least six distinct glacial advances during the last glacial cycle. These include four well-constrained Marine Oxygen Isotope Stage (MIS) 3 and 2 advances at ca. 38 ka, ca. 27 ka, ca. 21 ka and at 18 ka, as well as less well-constrained advances in MIS…
Understanding hydro-ecological surprises for riverine ecosystem management
Late-Holocene cliff-top blowout activation and evolution in the Cooloola Sand Mass, south-east Queensland, Australia
Cliff-top dunes are a locally important geomorphic features of sedimentary coasts. They are traditionally interpreted as being sourced by (or with) sand derived from the beach below the cliff. This paper presents the results of a stratigraphic and geochronological study of Carlo Sand Blow, a coastal blowout that has developed on top of a high sandy cliff in the Cooloola Sand Mass, south-east Queensland. We use a combination of sedimentological, p…

Glacial geomorphology of the Brabazon & Butler Downs, Rangitata Valley, South Island, New Zealand
The inland valleys of New Zealand’s South Island were heavily glaciated during the last glacial cycle. Subsequent fluvial incision has eroded out glacial deposits from the valleys in many locations, making it difficult to reconstruct glacial dynamics and chronology. The Brabazon and Butler Downs lie in a fault-controlled intra-montaine basin that has been largely protected from fluvial erosion and the area contains extensive evidence for multiple…
Reconstructing terrestrial temperatures in the Australian sub-tropics and tropics
Summer temperature variability inferred from subfossil chironomid assemblages from the south-east margin of the Qinghai–Tibetan Plateau for the last 5000 years
We present a quantitative mean July temperature record spanning the last c. 5000 years from an alpine lake in south-western China. The reconstruction is based on the application of an established chironomid-based inference model using 100 lakes from the region. The reconstructed summer temperature changes are within 2.4°C of modern throughout the record. The results suggest that the summer temperature changes in south-east margin of the Qinghai–T…
Geochemical investigation of the South Wellesley Island wetlands
The South Wellesley Islands in the Gulf of Carpentaria, northern Australia, were the recent focus of a palynological investigation which found vegetation change during the Holocene was driven by coastal progradation and regional climate. Here, we present new elemental data from x-ray fluorescence core scanning which provides non-destructive, continuous and high resolution analysis from three wetlands across Bentinck Island, the largest of the Sou…
Using Soil Magnetic Properties to Determine the Onset of Pleistocene Human Settlement at Gledswood Shelter 1, Northern Australia
In regions that lack built structures or stratified open archaeological sites, such as precolonial Australia, rockshelters are a major source of detailed information for understanding the nature and timing of human occupation. A key concern is that the proposed ages for the earliest archaeological sites are based on luminescence dating of sediments, rather than directly of cultural materials, leaving the association between the sediments and evid…
Contemporary Sorted Patterned Ground in Low Altitude Areas of Tasmania
This paper summarises the distribution of patterned ground phenomena in Tasmania. It presents observations of low altitude sorted stone circles forming on glacial and alluvial deposits in the vicinity of Queenstown, Western Tasmania. Evidence suggests that freeze-thaw derived patterned ground could develop in most inland valleys in Tasmania where cold air drainage causes sub-zero ground temperatures in winter and permits the formation of ground a…
Major disturbance to aquatic ecosystems in the South Island, New Zealand, following human settlement in the Late Holocene
Lake sediment records from three lakes in the South Island of New Zealand were examined to determine the effects of human (Māori and European) impacts on the lake catchments during the Late Holocene. Major changes in lake biota occurred in the Early to Middle Holocene (11,000–6000 cal. yr BP), but there were no major changes between c. 6000 cal. yr BP and the time of human impact. Intensive Māori forest clearance occurred here between c. ad 1200 …
A Holocene record of climate and hydrological changes from Little Llangothlin Lagoon, south eastern Australia
We present a new well dated Holocene record of environmental change from Little Llangothlin Lagoon in eastern Australia derived from aquatic plant macrofossils, macroscopic charcoal flux, and sediment stratigraphy from multiple cores. Little Llangothlin was an ephemeral freshwater wetland exhibiting frequent dry phases between 9800 and 9300 calendar years before present (cal. yr BP). There was a switch to a more positive water balance after 9300 …
Late Quaternary and Holocene environmental history of Groote Eylandt, Northern Australia
Pollen evidence from tropical Australia for the onset of an Enso-dominated climate at c. 4000 BP
The Holocene climatic history of tropical northern Australia is re-examined using the recently published pollen record from Groote Eylandt to corroborate and refine previous climatic inter pretations. We identify a four-stage Holocene comprising: (1) a continuous increase in effective precipitation (EP) from the beginning of the Holocene to about 5000 BP; (2) a mid-Holocene EP maximum from about 5000 to about 4000 BP; (3) a marked decline in EP s…

A Holocene Pollen record from Lowland Tropical Australia
A pollen record from a dunefield lake on Groote Eylandt, Northern Australia is presented. This is the first substantially complete Holocene terrestrial record from the seasonally humid lowland tropics of Northern Australia. The lake originated as a seasonal swamp prior to 10 000 BP. A progressive rise in water tables occurred until a permanent lake was established at about 9000 BP. From 9000 to 7500 BP the lake shows evidence of disruption in the…

Re-envisioning the structure of last glacial vegetation in New Zealand using beetle fossils
A series of 18 fossil beetle assemblages are used to reconstruct the paleoenvironment of the northwest West Coast, New Zealand, over the period of the last interstadial–stadial transition (ca. 37,000–21,300 cal yr BP). The samples were recovered from an in-filled hollow within a dune field ca. 9 km south west of Westport (41°47′S, 171°30′E). This fossil beetle reconstruction is compared to an existing palynological reconstruction from the same si…
