The East Antarctic Ice Sheet is the largest repository of fresh water on the planet and represents the greatest potential contribution to sea-level rise, yet little is known about its thermal and mechanical conditions, as well as its potential for ice-mass loss. It also contains the oldest meteoric and atmospheric gas climate records on the planet; exploration for and utilization of those records is key to reliable modeling of climate variations in the near- and mid-term future. Exploration of the interior of the East Antarctic ice sheet has proceeded slowly but steadily over several decades, mainly through remote sensing technologies. Despite great progress, pressing questions remain about Earth\u0027s climate \u003e1 m.y. ago, ice deformation, geothermal heat flow, basal material properties, and subglacial geology. These problems are best addressed by quickly penetrating to the glacial bed of Antarctic ice sheets, retrieving ice core and rock core samples, and providing boreholes for down-hole logging of physical properties in ice. This is made possible by the US Rapid Access Ice Drill, developed as a new drilling technology capable of direct access. It has been tested in the field in Antarctica and is now ready for scientific research. The Principal Investigators of this award will convene a workshop in 2024 to support research community use of the Rapid Access Ice Drill in Antarctica. Workshop participants will meet to consider how the drilling system can best be used to advance our understanding of current operative ice-sheet processes, past climate records, history of ice-sheet development, and the geological substrate to the East Antarctic ice sheet, all of which have societal relevance. Research scientists with relevant experience will meet to guide how, when and where the Rapid Access Ice Drill will be used for exploration for the oldest ice, to validate airborne radar imaging of glacial layers, to observe the conditions at the base of the ice sheet, and to recover cores of subglacial rock samples for laboratory analysis. The workshop will emphasize participation by early-career researchers who represent the next generation of polar scientists to engage in Antarctic research at the critical cryosphere-geosphere boundary.

Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.
Viewing map layers on the Results Map
Older retrieved projects from AMD. Warning: many have incomplete information.
To sort the table of search results, click the header of the column you wish to search by. To sort by multiple columns, hold down the shift key whilst selecting the sort columns in order.
