maps and chart - Spatial map of southern Weddell Sea with summer (DJF) climatology and anomalies for sea ice concentration (SIC; a–d), zonal wind (e–h), and ocean surface stress curl (i–l).

Overview map of the Filchner Trough region in the eastern part of the southern continental shelf in the Weddell Sea. The bathymetry is from IBCSO (Arndt et al., 2013) with marked contours every 100 m. Grounded ice is shaded dark gray and floating ice shelves are light gray. Mooring locations are marked with colored circles, historic CTD casts with gray dots, and the deployment location of the APEX floats as diamonds. Red and blue arrows are a sketch of the circulation of relevant water masses, mWDW and ISW, respectively. The inset in the upper left shows the location of the study site.

maps and charts:
(a) Velocities from the moorings averaged within 0.1°C temperature bins
(b) Temperature (according to colorbar) along the float trajectories of Fst (brown diamond, through the Small Trough), Fsill (green diamond, along the eastern flank), and Fcs (purple diamond, within the Filchner Trough) at their parking depths of 400, 400, and 250 metres, respectively.
(histograms) temperature bins within the temperature ranges of ISW and mWDW.

Iced out? Research on the Great Lakes goes ahead amid funding chaos. | Great Lakes Now

“(The) Great Lakes is losing ice over the long term,” said Ayumi Fujisaki-Manome, associate research scientist for the Cooperative Institute for Great Lakes Research at the University of Michigan. “We still get high ice in some years, even recently, but if we draw a trend line over the long-term, we do see a decreasing trend.”

Department of Environmental Conservation invites public to report when #Vermont’s lakes and ponds lose their #IceCover. Tracking ice-out dates helps scientists decide when to begin seasonal #WaterQuality sampling efforts. https://www.morningagclips.com/vermont-dec-seeks-lake-ice-observations-from-the-public/

❄️#MOSAiC expedition provided a comprehensive view of the physical properties of the #Arctic snow and #icecover over an entire annual cycle.

The study identified large #spatialvariabilities of #snowmetamorphism and thermal regimes impacting #seaice growth.

#H2020

One of the main news items at the moment is the recent #heatwaves and record low July #iceCover in the #Antarctic. However July in Finland didn't feel particularly warm. That got me wondering what the situation with the #Arctic might be and why I haven't seen that mentioned in the news.

Indeed, while Arctic #ice levels are still low compared to longer term medians, they are not record low. Temperatures also have been 'unremarkable'.
