    The 8th International Ice Drill Symposium Report of Contributions https://indico.nbi.ku.dk/e/1121 The 8th Internati … / Report of Contributions Impurities effect on borehole closu … Contribution ID: 2 Type: Poster Impurities effect on borehole closure rate in ice sheet Monday, 30 September 2019 17:56 (4 minutes) Understanding ice sheet dynamics is of high interest to predict the future ice sheet response in times of changing climate, and is also crucial to estimate borehole closure rate during accessing ice sheet especially by deep ice core drilling. Impurities in ice is one of the most influential factors on mechanical properties of ice and causes localized enhanced deformation. High concentrations of impurities is the main driver for development of strong crystal prefrred orientation, fine grain sizes and for decreasing pressure melting point, which favors the borehole clousre rate signaficantly particularly when ice temperature is above -10 ℃. While the control mechanism of impurities on ice deformation rate is still remains much unclear. Thus, we propose to investigate various species and concentrations of impurities effect on ice creep rate between -15 ℃ to -5 ℃ using bubble free, labratory-made polycrystalline ice obtained by isotropic freezing method, in order to figure out the critical species and concentrations of impurities on borehole closure rate.

Deep-water ‘stable’ subglacial lakes likely contain microbial life 15 adapted in isolation to extreme environmental conditions. How water is sup- 16 plied into a subglacial lake, and how water outflows, is important for under- 17 standing these conditions. Isochronal radio-echo layers have been used to infer 18 where melting occurs above Lake Vostok and Lake Concordia in East Antarc- 19 tica but have not been used more widely. We examine englacial layers above 20 and around Lake Ellsworth, West Antarctica, to establish where the ice sheet 21 is ‘drawn down’ towards the bed and, thus, experiences melting. Layer draw- 22 down is focused over and around the NW parts of the lake as ice, flowing 23 obliquely to the lake axis, becomes afloat.

The content of this report is guided by the Project’s Socio-Economic Monitoring Plan (i.e. Sabina 2018a). More specifically, Sabina’s reports are intended to assess the socio-economic performance of the Project as it progresses from construction through operations and eventual closure. The Project remained in the pre-construction phase in 2019. Some Project employment, training, and business opportunity information was available for 2019. A total of 310 individuals worked on the Project, completing 145,171 hours of work. Of this, 49 Inuit worked on the Project, completing 21,735 hours of work (or 15.0% of total hours worked).

Thus, dynamic conditions support efficient mixing of nutrient- and oxygen-enriched meltwater derived from the overlying ice, which is essential for biome support within the water column. We caution that accreted ice analysis cannot always be used as a proxy for water sampling of lakes beneath a thin (<3.166 kilometers) ice cover, because a stable layer isolates the well-mixed bulk water from the ice-water interface where freezing may occur.

The geometry and internal structure of IRHs can reveal the cumulative effects of surface mass balance, strain, basal melt and ice dynamics, to improve understanding of the glacial history of West Antarctic Ice Sheet (WAIS). Despite the airborne-surveyed IRHs however, international efforts to develop a continental-wide scale coverage of IRHs (i.e. AntArchitecture), are limited by a lack of data in the critical regions between the upper reach of Pine Island Glacier (PIG), Rutford Ice Stream (RIS) and Institute Ice Stream (IIS). This region is important because any significant collapse of WAIS or reorganisation of ice flow would likely be felt in the ESH because it hosts deep subglacial troughs (Ellsworth Trough and CECs Trough), that represent a potential connection between the Weddell and Amundsen Seas.

    Lakes Isolated Beneath Antarctic Ice Could Be More Amenable to Life Than Thought 17 February 2021

    Lakes isolated beneath Antarctic ice could be more amenable to life than thought 17 February 2021 many of which have been isolated from each other and the atmosphere for millions of years. This means that any life in these lakes could be just as ancient, providing insights into how life might adapt and evolve under persistent extreme cold conditions, which have occurred previously in Earth's history. Expeditions have successfully drilled into two small subglacial lakes at the edge of the ice sheet, where water can rapidly flow in or out. These investigations revealed microbial life beneath the ice, but whether larger lakes isolated beneath the central ice sheet contain and sustain life remains Ellsworth Mountains, on transit to Subglacial Lake an open question.
