Seafloor geomorphology of western Antarctic Peninsula bays: a signature of ice flow behaviour Yuribia P. Munoz1, Julia S. Wellner1 1Department of Earth and Atmospheric Sciences, University of Houston, Houston, Texas 77204 USA 5 Correspondence to: Y.P. Munoz ([email protected]) Abstract. Glacial geomorphology is used in Antarctica to reconstruct ice advance during the Last Glacial Maximum and subsequent retreat across the continental shelf. Analogous geomorphic assemblages are found in glaciated fjords and are used to interpret the glacial history and glacial dynamics in those areas. In addition, understanding the distribution of 10 submarine landforms in bays and the local controls exerted on ice flow can help improve numerical models by providing constraints through these drainage areas. We present multibeam swath bathymetry from several bays in the South Shetland Islands and the western Antarctic Peninsula. The submarine landforms are described and interpreted in detail. A schematic model was developed showing the features found in the bays; from glacial lineations and moraines in the inner bay, to grounding zone wedges and drumlinoid features in the middle bay, and streamlined features and meltwater channels in the 15 outer bay areas. In addition, we analysed local variables in the bays and observe that: 1) the number of landforms found in the bays scales to the size of the bay, however the geometry of the bays dictates the types of features that form, specifically, we observe a correlation between the bay width and the number of transverse features present in the bays; 2) the smaller seafloor features are present only in the smaller glacial systems indicating that short-lived atmospheric and oceanographic fluctuations, responsible for the formation of these landforms, are only recorded in these smaller systems; and 3) meltwater 20 channels are abundant on the seafloor, however some are subglacial, carved in bedrock, and some are modern erosional features, carved on soft sediment. -

Global Warming Can Alter Shape of the Planet, As Melting Glaciers Erode the Land
News date: October 1, 2015 compiled by Dr. Alvarinho J. Luis Global warming can alter shape of the planet, as melting glaciers erode the land Climate change is causing more than just warmer oceans and erratic weather. According to scientists, it also has the capacity to alter the shape of the planet. In a five-year study published today in Nature, lead author Michele Koppes from the University of British Columbia, compared glaciers in Patagonia and in the Antarctic Peninsula. She and her team found that glaciers in warmer Patagonia moved 100 to 1,000 times faster and caused more erosion than those in Antarctica, as warmer temperatures and melting ice helped lubricate the bed of the glaciers. Antarctica is warming up, and as it moves to temperatures above zero degrees Celsius, the glaciers are all going to start moving faster. We are already seeing that the ice sheets are starting to move faster and should become more erosive, digging deeper valleys and shedding more sediment into the oceans. The repercussions of this erosion add to the already complex effects of climate change in the polar regions. Faster moving glaciers deposit more sediment in downstream basins and on the continental shelves, potentially impacting fisheries, dams and access to clean freshwater in mountain communities. The polar continental margins in particular are hotspots of biodiversity, notes Koppes. If you're pumping out that much more sediment into the water, you're changing the aquatic habitat. The Canadian Arctic, one of the most rapidly warming regions of the world, will feel these effects acutely. -

Response to Interactive Comments For: Seafloor Geomorphology of Western Antarctic Peninsula Bays: a Signature of Ice Flow Behaviour
Response to interactive comments for: Seafloor geomorphology of western Antarctic Peninsula bays: a signature of ice flow behaviour We want to thank the reviewers and the editor for their constructive and insightful comments. We have made revisions to the 5 manuscript based on the comments provided by the referees. The annotated document with track changes is tc-2017-108- AC1-supplement. Below are answers to specific reviewers’ comments followed by the revised manuscript with track changes (underlined are the reviewer comments, followed by the author comments in red). 10 C. Stokes: Include 1) a much clearer and explicit presentation of the mapped data, 2) a clearer and more objective separation of the results from the interpretations, and 3) a more in-depth and critical analysis in the discussion. Y. Munoz: 15 1) We have included interpretation maps for all the bays mentioned in this paper. In addition, we have included a table describing the criteria used for identifying the features mentioned in the study and we have annotated Fig. 6 which shows examples of the seafloor features mapped. 2) The results have been clearly separated from the interpretations. Results only describe the geomorphology present in the bays as well as geometries of landforms, and interpretation of these landforms is now in the first section of the discussion. 20 3) The discussion section has been modified to include the interpretation of geomorphic features and some sub-sections have been removed to avoid repetition. A.G.C. Graham: 25 1) the authors might want to consider their method and whether it is still adequate to simply present sea-floor data without a clear and objective mapping of the landforms alongside. -

In birds, most of observed cases concern passerines and this behavior has so far never been described among seabirds.

Monitoring'2020
Monitoring’2020 Geological research during 25-th Ukrainian Antarctic Expedition, February – April 2020: Kiev Peninsula of the Graham Coast O. Mytrokhyn (Taras Shevchenko National University of Kyiv), V. Bakhmutov (Institute of Geophysics of the National Academy of Sciences, National Antarctic Scientific Center) SUMMARY From February to April 2020 the authors carried out geological survey on the Graham Coast of the West Antarctica. The survey was a part of the seasonal researches of 25-th Ukrainian Antarctic Expedition supported by National Antarctic Scientific Center. Studied area was the mainland of the Kiev Peninsula from the Girard Bay to the Collins Bay and nearby islands. It was found out that outcrops of varied intrusive rocks are widely distributed in the inner part of the Kiev Peninsula of the Graham Coast. They are represented by plutonic and hypabyssal facies. Granitoids prevail among other petrographic representative of the intrusive rocks. Granites and granodiorites intrude in the Jurassic volcanites and Early-Cretaceous gabbroids in the Waddington Bay to Bussey Glacier aria. Studied granitoids can belong to the different intrusive complexes. To find out their relative ages it is necessary to complete additional routes on the west slopes of the Mount Mill and Guys Cliff. The parts of the large gabbroic intrusion are exposed in the inner part of the Girard Bay and are intruded by granitoids. Their geological position, age and petrography also need more researches. Erratic boulders additionally confirm the abundance of the granitoids in the inner part of the Kiev Peninsula. Among them red coarse granite deserve special attention as in relation to finding their bedrock and also to the reconstructions of the ancient glaciation namely its extent, thickness and travel routes. -
