A lot of people are surprised when I mention that I work with Antarctic plants. Contrary to popular belief, Antarctica is home to a variety of plant life, including vascular plants and mosses, as well as algae and the symbiont lichens. Indeed scientists have succesfully mapped the ice-free regions where these remarkable organisms thrive in Antarctica, but little that we know about the actual plants distribution on a continental scale. This advancement in mapping Antarctic plant distribution is a significant step forward in understanding their presence in ice-free regions. It is a great achievement for the scientific community, a crucial tool for tracking climate change impacts on the accelerated plant expansion in Antarctica, and an essential resource for conservation efforts to protect these unique ecosystems.
Close your eyes and picture Antarctica. Done? Guessing you didn't picture any plants... Did you know there's moss, lichen and algae specially adapted to Antarctica's harsh conditions? Now, for the first time, plant life across all of Antarctica has been mapped. That's a big old task, led by Charlotte Walshaw from The University of Edinburgh with Norwegian Institute for Nature Research, British Antarctic Survey and Scottish Association For Marine Science. This new info is the crucial baseline data we'll use to track how cold places change with the climate 🌱 https://lnkd.in/gRdS6P4p 📸 Felix Grewe #remotesensing #GIS #antarctica

The West Antarctic Ice Sheet is the frontier of dramatic ice loss in Antarctica, and one of the most rapidly changing ice sheets on earth. It is undisputed that ice loss across West Antarctica is increasing and accelerating. Exactly how much, and how quickly this ice will flow, calve and melt into the ocean is one of the areas of greatest uncertainty in climate science today. There are fears that as the West Antarctic Ice Sheet melts, it could contribute over 10 feet (3 meters) to rising sea levels within the next two hundred years. A worst case climate scenario could see these changes occuring much more quickly. Professor Poul Christoffersen, a member of the Centre of Excellence in Antarctic Science and the Australian Antarctic Program Partnership, will share his research and discuss the Western Antarctic ice sheet dynamics and climate change in polar regions. He will further extend the conversation with Dr Adrian McCallum.

🌊 ❄ I knew Antarctica's sea-ice was important, but I really didn't understand how important. 📫 Day 6️⃣ in the seven-day Antarctic Climate Visuals Series, inspired by the Science Media Centre of New Zealand’s ‘Expert Reaction’ piece “Climate Change is taking a toll on every aspect of Antarctica” (https://lnkd.in/gHUt8g-S) I have Dr Natalie Robinson ( NIWA) to thank for helping me understand the importance of Antarctic sea-ice. 🙏 💯 Natalie really succinctly summed up the five ✋ most important effects that sea-ice has on the 🌏 global climate system. I felt her summary lent itself nicely to a quick little slide-show-style video. ▶ #SciComm #SciComNZ #DataViz #DataVis #Antarctica #Antarctic #ClimateEmergency #SeaIce #DataVisualisation #DataVisualization #ClimateCrisis #ClimateEmergency #ClimateChange #ClimateAction #AntarcticScience #Science #PolarScience #ScienceCommunication #DesignerForHire #ClimateVisuals cc: Antarctica New Zealand

Bridging the gap for ice–ocean–ecosystem processes: integrated observing system for the ROSS Sea-far East Antarctic Region - Frontiers in Marine Science Our understanding of cross-disciplinary connections for Antarctica's role in the Earth system remains incomplete, especially around its coastal margins. The focus here is on sea-ice, oceanic, and atmospheric drivers in the joint ROSS Sea-far East Antarctic Region (RSfEAR)—one which spans a large longitudinal range and connects a number of ice shelves and polynyas promoting sea-ice growth and underpinning a diverse and rich ecosystem. Here, we present a minireview of recent case studies and how these inform the design for a future integrated ocean–sea ice–atmosphere observing system. The review is built around five themes: i) regional setting, ii) recent studies in the region and current strategies, iii) gap analysis, iv) future observing system design, and v) wider implications for stakeholders.

In this video by NCI VizLab of ice-ocean dynamics near the Denman Glacier, you can see the offshore eddies spinning the Antarctic sea ice; the sea-ice factories of open water near the coast called ‘polynyas’; the smaller-scale near-shore ocean movements where it’s shallower; and the sea ice torn apart by wind and currents. This high-resolution computer simulation is generated with the MIT General Circulation Model by University of Tasmania, CSIRO and ARC Australian Centre for Excellence in Antarctic Science. To model processes as complex and inaccessible as #Antarctic ice-ocean dynamics needs the superpowers of the National Computational Infrastructure.

Antarctica allows scientists to explore Earth’s past climates, understand the forces that shape today’s #climate, and predict what changes to the continent — and globally — will affect the future. Recent publications from the National Academies explore the importance of scientific research in Antarctica and the importance of U.S. leadership in Antarctic research.
