#QRA2025

Delighted to give this new research a bit of an airing today on the #QRA2025 field trip to Blast Beach - thanks for the invite to talk @iceybethan.bsky.social

Really enjoyed presenting my research on glacial geomorphology and glaciolacustrine varves at #QRA2025 this week. Thanks to everyone who came and spoke with me! I'm now enjoying the frosty morning train home with my latest @quaternaryra.bsky.social field guide purchase 📖

Slide showing study sites in Ellie Nelson's presentation

A virtual Ellie Nelson @ellienelson12.bsky.social talking at the #QRA2025 about the time/temp complexities when AA dating across such a large region over the #Pleistocene - thanks to the @quaternaryra.bsky.social audience for the helpful ideas :-)

Poster summarising our Big Thaw Nepal project

Our Big Thaw Nepal lake coring project summarised as a poster presented at the #QRA2025 meeting in Newcastle this week …

Now taking on the mantle is Mahjoor Lone, taking the theme of speleothems to the Northern Sahara to constrain past rainfall. #QRA2025

Now we have Mike Rogerson, presenting his work on speleothem growth in caves, compiling hundreds of U-series dates from across the UK. This gives a long precipitation record over several glacial cycles and helps constrain glaciation. #QRA2025

Now we have Mark Bateman from Sheffield Uni, focusing on tsunami in SW Ireland, where oral histories talk about great waves hitting Ireland. Mark has been searching for physical evidence of these tsunamis in Ireland, using portable luminescence and stratigraphic analysis. #QRA2025

For our final presentation today at #QRA2025 we have Chloe Snowling, presenting her exciting work on the SE Asian Monsoon during a glacial inception.

@celiavarves.bsky.social is now doing a deep dive into insights into Holocene palaeoclimates from varved lake sediments in her @quaternaryra.bsky.social #QRA2025 keynote lecture. Fascinating details given in these annually resolved lake records

Important advice from @celiavarves.bsky.social on how and why to consider policy and impact right from the start of a research project. #QRA2025

Now we have a great interactive talk with @celiavarves.bsky.social talking about Quaternary Science and policy and near-term climate projections. Celia is talking about past climates informing our future, integration with the IPCC, and palaeoclimate for policy #QRA2025 @quaternaryra.bsky.social

Springtails are mostly found where nunataks have been ice free since at least the global LGM, and potentially since the late Pliocene. @emlcpeer.bsky.social #QRA2025

Last talk before the lunch break we have another exciting application of cosmogenic isotopes, this time paired with biological archives from the Antarctic springtail to understand ice-free sectors in Antarctica by @emlcpeer.bsky.social from Monash University in Melbourne #QRA2025

Now more cosmogenics but this time in Ireland, with Clara Crowell from University College Dublin presenting her work on palaeonunataks in Ireland using 14C and 10Be @arctic-glacial.bsky.social #QRA2025

Now Dave Roberts from @geogdurham.bsky.social is presenting his NEGIS project looking at ice sheet reconstruction in northern Greenland. This rather epic project used 1000 m elevation range altitudinal transects to constrain ice sheet thinning #cosmogenicisotopes #QRA2025 @quaternaryra.bsky.social

Dealing with the amount of data available from the present day empirical datasets is challenging at the ice sheet scale and requires data reduction to summarise detailed landform data. These packages can then be grouped into flowsets and a relative age chronology @fegbutcher.bsky.social #QRA2025

Next up is @fegbutcher.bsky.social presenting a 23-stage reconstruction of Scandinavian Ice Sheet based on subglacial lineation record #QRA2025. This uses 1-2 m pixel DEMs available over Scandinavia to show an incredible range of landforms. These data are so important for data-model comparisons

@alexmclark.bsky.social uses these datasets to provide a detailed reassessment of flow dynamics during the last glaciation in Ireland #QRA2025

Moving on to Terrestrial landforms and archives of change, we now have Alex Clark from RHUL presenting his PhD research on the detailed mapping of glacial geomorphology of northern Ireland, showing the evolution of ice dynamics in this area #QRA2025

Final talk of this session is by Charlotte Greenall, presenting her PhD research on Antarctic phytoplankton changes over the Holocene using ancient DNA and fossil diatoms. These data show how sea ice, meltwater and upwelling have changed in the Antarctic Peninsula #QRA2025

These datasets provide insights into the movement of the subpolar gyre in the mid-Holocene, resulting in changing oceanic currents in the North Atlantic #QRA2025

Sticking with the north, we now have Jane Earland from Exeter Uni exploring the LateGlacial and Holocene palaeoenvironments of the Fetlar Basin in the Shetland Islands. Jane has been using high resolution marine sediment cores to explore environmental change. #QRA2025

Now we're heading to NW Scotland and the Minch Ice Stream with Neil McDonald at University of Stirling. Neil has been studying marine ice sheet instability in Scotland. Understanding these processes are very important for understanding how contemporary West Antarctic Ice Sheet may evolve #QRA2025

Full house for our first keynote speaker, Prof. Nina Kirchner, presenting her amazing work leading glaciological research in northern Greenland and Sweden, with interesting insights on co-production of knowledge and collaboration and communication of data results #QRA2025 @quaternaryra.bsky.social

Gareth Wood has been compiling multiple different datasets at different resolutions and using different methods (cores, geophysical data, seismic) to bring order to the poorly understood sediments here. There are beautiful submarine geomorphological features being shown #QRA2025.

Moving across to the eastern Irish Sea we now have Gareth Wood talking about the Last Glacial Environment, and delighted to have Gareth here for his first @quaternaryra.bsky.social meeting #QRA2025. These datasets are really important for siting windfarms and clean power generation

Amy McGuire is using proxy records from peat from these cores to calculate air temperature, vegetation and environment at 1 million years ago in the sustained land bridge in Doggerland in the current North Sea. #QRA2025

Please spread the word about #QRA2025 @chrisdclark.bsky.social @chrisdarvill.bsky.social @christinebatchelor.bsky.social @jeremyely.bsky.social @proftashabarlow.bsky.social @arctic-glacial.bsky.social

This work builds on cores from the super-cool RISER project led by Prof. @proftashabarlow.bsky.social #QRA2025
