A Textural Approach to Improving Snow Depth Estimates in the Weddell Sea by M. Jeffrey Mei, Ted Maksym

“…Here, we apply a textural segmentation algorithm to classify and group similar textures to infer the distribution of snow using snow surface freeboard measurements from Operation IceBridge campaigns over the Weddell Sea. We find that texturally-similar regions have similar snow/ice ratios, even when they have different absolute snow depth measurements. …”

Antarctic Seabed Assemblages in an Ice-Shelf-Adjacent Polynya, Western Weddell Sea by Bétina A. V. Frinault, Frazer D. W. Christie, Sarah E. Fawcett, Raquel F. Flynn, Katherine A. Hutchinson, Chloë M. J. Montes Strevens, Michelle L. Taylor, Lucy C. Woodall, David K. A. Barnes

“…This study investigated seafloor assemblages, by taxa and functional groups, in a coastal polynya adjacent to the Larsen C Ice Shelf front, western Weddell Sea. The study area is rarely accessed, at the frontline of climate change, and located within a CCAMLR-proposed international marine protected area. …”

Southern Weddell Sea surface freshwater flux modulated by icescape and atmospheric forcing by L. Stulic, R. Timmermann, S. Paul, S. Paul, R. Zentek, G. Heinemann, T. Kanzow

“…<p>Sea ice formation dominates surface salt forcing in the southern Weddell Sea. Brine rejected in the process of sea ice production results in the production of High Salinity Shelf Water (HSSW) that feeds the global overturning circulation and fuels the basal melt of the adjacent ice shelf. …”

Seasonal resonance of diurnal coastal trapped waves in the southern Weddell Sea, Antarctica by S. Semper, E. Darelius

“…The summer enhancement of diurnal tidal currents at the shelf break in the southern Weddell Sea is studied using velocity measurements from 29 moorings during the period 1968 to 2014. …”

Noble gas tracers of ventilation during deep-water formation in the Weddell Sea by Nicholson, D, Khatiwala, S, Heimbach, P

“…In addition to these modeled processes, a volumetric contribution of 0.28 ± 0.07% of glacial melt water is required to reconcile deep-water observations in the Weddell Sea. Another primary finding of our work is that the saturation anomaly of heavy noble gases in model simulations is in excess of two-fold more negative than is suggested from Weddell Sea observations. …”

Stirring across the Antarctic Circumpolar Current's southern boundary at the prime meridian, Weddell Sea by R. Oelerich, R. Oelerich, R. Oelerich, K. J. Heywood, G. M. Damerell, G. M. Damerell, M. du Plessis, L. C. Biddle, L. C. Biddle, S. Swart, S. Swart

Sudden, local temperature increase above the continental slope in the southern Weddell Sea, Antarctica by E. Darelius, V. Dundas, M. Janout, S. Tippenhauer

“…Similar trends, on the order of 0.05 <span class="inline-formula">^∘</span>C and 3 m per decade, have been observed in the Warm Deep Water (WDW), the slightly cooled CDW derivative found at depth in the Weddell Sea. Here, we report on a sudden, local increase in the temperature maximum of the WDW above the continental slope north of the Filchner Trough (74<span class="inline-formula">^∘</span> S, 25–40<span class="inline-formula">^∘</span> W), a region identified as a hotspot for both Antarctic Bottom Water formation (AABW) and potential changes in the flow of WDW towards the large Filchner–Ronne Ice Shelf.…”
