The year-long #MOSAiC expedition to the #Arctic Ocean, coordinated by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research and CIRES/NOAA: National Oceanic & Atmospheric Administration, was my first field-going experience as a modeller. During the expedition, a network of autonomous ice-tethered systems (the "Distributed Network", DN) was deployed that aimed to bridge gaps in our understanding of temporal and spatial scales. In particular, sub-grid variability present in areas representative for typically-sized grid boxes of current #Earth system models was sampled. The close link between the expedition setup and current modelling strategies I find as exciting as ever. A couple of days ago our paper on the DN network was finally published in Elementa/University of California Press : 🌐 https://lnkd.in/eN9ziSnh With grid-box sizes well below 10 km (e.g., 4.4 km), the nextGEMS | next Generation Earth Modelling Systems and the Climate Adaptation Digital Twins in #DestinE I am working on at the European Centre for Medium-Range Weather Forecasts now resolve linear kinematic features in the sea ice cover (https://lnkd.in/eATAZApz) and the scale of the DN with tens to hundreds of points.

Abstract:"Ultracool dwarf stars are abundant, long-lived and uniquely suited to enable the atmospheric study of transiting terrestrial companions with the JWST. Among them, the most prominent is the M8.5V star TRAPPIST-1 and its seven planets. While JWST Cycle 1 observations have started to yield preliminary insights into the planets, they have also revealed that their atmospheric exploration requires a better understanding of their host star. Here we propose a roadmap to characterize the TRAPPIST-1 system — and others like it — in an efficient and robust manner with JWST. We notably recommend that — although more challenging to schedule — multi-transit windows be prioritized to mitigate the effects of stellar activity and gather up to twice more transits per JWST hour spent. We conclude that, for such systems, planets cannot be studied in isolation by small programmes but rather need large-scale, joint space- and ground-based initiatives to fully exploit the capabilities of JWST for the exploration of terrestrial planets." https://lnkd.in/ghb-qrZp A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST TRAPPIST-1 JWST Community Initiative

🧊 WHOI’s revolutionary Self-deploying Autonomous Mooring System will conduct long-term missions in hostile, difficult-to-reach locations that are Ground Zero for global sea-level rise >> https://hubs.la/Q02LJc8N0 📢 WHOI scientist Catherine Walker said, “Of all the things that drive global sea-level rise, the response of Antarctic ice shelves to continued warming—from the air above and the ocean below—represents one of the biggest question marks. “So far, scientists have been able to send underwater vehicles under ice shelves to make measurements for relatively short periods. What we really need are continuous long-term observations to fill that gap in our knowledge about the planet.” 👏 🌊 Visit the Ocean Science & Technology website for further information.

Recent findings from NASA - National Aeronautics and Space Administration reveal a surprising twist in the Arctic: North America's Mackenzie River runoff is causing the Beaufort Sea to emit more CO2 than it absorbs. The Arctic Ocean, once seen as a climate stabilizer, now stands as a poignant reminder of the far-reaching consequences of environmental change. As the Arctic warms, understanding these dynamics becomes crucial for predicting climate impacts. Let's delve into the complexities of Arctic carbon cycles.

Study published today in the journal Nature Geoscience Nature Portfolio, led by scientists at our Cooperative Institute for Marine and Atmospheric Studies (CIMAS) Atlantic Oceanographic and Meteorological Laboratory (AOML), and Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, shows that a critical piece of the Atlantic Meridional Overturning Circulation in the North Atlantic has weakened by about 12% over the past two decades. “Our observational analysis matches what the numerical models have predicted—human activity could potentially impose circulation changes on the entire ocean,” said Tiago Biló, an assistant scientist at the Rosenstiel School’s CIMAS. “This analysis was only possible because of the decades of collective planning and efforts by multiple oceanographic institutions worldwide.” Read more 👇 https://lnkd.in/eDGRkXqK #AtlanticMeridionalOverturningCirculation #ClimateChange #oceanscience
