Yet little is known about the glacial evolution of the catchment and the factors influencing its present and past behavior. Due its remote location and heavy sea ice, the continental shelf in front of the Totten Glacier had not been comprehensively surveyed prior to this study. Satellite observations indicate that the Totten ice drainage system is thinning, and it has been hypothesized that this thinning is in response to undermelting by warm ocean waters over the continental shelf. While this process is observed elsewhere in Antarctica (e.g. the rapidly retreating Pine Island Glacier in West Antarctica), the Totten Glacier system is potentially Antarcticas most important glacial drainage system due to its large size; it is three times larger than any system in West Antarctica. \u003c/br\u003eThe main goals of this proposal were: \u003c/br\u003eTo generate multibeam bathymetric maps of the continental shelf proximal to the Totten Glacier system to understand the recent regional glacial history and to document the pathways, if any, for circumpolar deep water to move onto the shelf. \u003c/br\u003eTo conduct a physical oceanographic survey of the region proximal to the Totten Glacier system, to determine the presence, if any, of warm ocean waters over the continental shelf.\u003c/br\u003eTo conduct a seismic survey of the continental shelf to assess the long-term evolution of the glacial system in the Aurora Subglacial Basin.\u003c/br\u003eTo collect marine sediment cores to determine the regional deglacial to Holocene climate history and the influence of warm circumpolar deep water.", "east": 146.0, "geometry": ["POINT(131.5 -66.5)"], "keywords": "Antarctica; Diatom; NBP1402; Totten Glacier", "locations": "Totten Glacier; Antarctica", "north": -66.0, "nsf_funding_programs": "Antarctic Integrated System Science", "persons": "NBP1402 science party; Leventer, Amy", "project_titles": "Collaborative Research: Totten Glacier System and the Marine Record of Cryosphere - Ocean Dynamics", "projects": [{"proj_uid": "p0000008", "repository": "USAP-DC", "title": "Collaborative Research: Totten Glacier System and the Marine Record of Cryosphere - Ocean Dynamics"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -67.0, "title": "NBP1402 diatom data", "uid": "601258", "west": 117.0}, {"awards": "1313826 Orsi, Alejandro", "bounds_geometry": ["POLYGON((119 -66,119.3 -66,119.6 -66,119.9 -66,120.2 -66,120.5 -66,120.8 -66,121.1 -66,121.4 -66,121.7 -66,122 -66,122 -66.1,122 -66.2,122 -66.3,122 -66.4,122 -66.5,122 -66.6,122 -66.7,122 -66.8,122 -66.9,122 -67,121.7 -67,121.4 -67,121.1 -67,120.8 -67,120.5 -67,120.2 -67,119.9 -67,119.6 -67,119.3 -67,119 -67,119 -66.9,119 -66.8,119 -66.7,119 -66.6,119 -66.5,119 -66.4,119 -66.3,119 -66.2,119 -66.1,119 -66))"], "date_created": "Mon, 24 Dec 2018 00:00:00 GMT", "description": "An array of three moorings (M1-M3) with current meters, temperature, conductivity, and pressure (TCP) recorders were deployed along the eastern flank of the continental shelf off Sabrina Coast, at the main path of the Antarctic Coastal Current indicated by the uCTD data collected earlier during the cruise.\r\n\r\nThese three US mooring were deployed at the 625-m (M1), 620-m (M2) and 1051-m (M3) isobaths.\r\n M1 was recovered on 25 February 2014, with a full data return from all of its instruments; whereas M2 and M3 were recovered in early 2015 on board of the Australian RVI Aurora Australis next year (cruise AU1402).\r\n\r\nThe location and schematics of the mooring array design is described below, and also provided among the uploaded files.\r\n", "east": 122.0, "geometry": ["POINT(120.5 -66.5)"], "keywords": "Antarctica; Au1402; Mooring; NBP1402; Oceans; Ocean Temperature; Physical Oceanography; R/v Aurora Australis; R/v Nathaniel B.

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.

Collaborative Research: Totten Glacier System and the Marine Record of Cryosphere - Ocean Dynamics |
Totten Glacier is the termination of the largest marine-based portion of the East Antarctic Ice Sheet, the Aurora Subglacial Basin. Yet little is known about the glacial evolution of the catchment and the factors influencing its present and past behavior. Due its remote location and heavy sea ice, the continental shelf in front of the Totten Glacier had not been comprehensively surveyed prior to this study. Satellite observations indicate that the Totten ice drainage system is thinning, and it has been hypothesized that this thinning is in response to undermelting by warm ocean waters over the continental shelf. While this process is observed elsewhere in Antarctica (e.g. the rapidly retreating Pine Island Glacier in West Antarctica), the Totten Glacier system is potentially Antarcticas most important glacial drainage system due to its large size; it is three times larger than any system in West Antarctica. </br>The main goals of this proposal were: </br>To generate multibeam bathymetric maps of the continental shelf proximal to the Totten Glacier system to understand the recent regional glacial history and to document the pathways, if any, for circumpolar deep water to move onto the shelf. </br>To conduct a physical oceanographic survey of the region proximal to the Totten Glacier system, to determine the presence, if any, of warm ocean waters over the continental shelf.</br>To conduct a seismic survey of the continental shelf to assess the long-term evolution of the glacial system in the Aurora Subglacial Basin.</br>To collect marine sediment cores to determine the regional deglacial to Holocene climate history and the influence of warm circumpolar deep water. | ["POLYGON((117 -66,119.9 -66,122.8 -66,125.7 -66,128.6 -66,131.5 -66,134.4 -66,137.3 -66,140.2 -66,143.1 -66,146 -66,146 -66.1,146 -66.2,146 -66.3,146 -66.4,146 -66.5,146 -66.6,146 -66.7,146 -66.8,146 -66.9,146 -67,143.1 -67,140.2 -67,137.3 -67,134.4 -67,131.5 -67,128.6 -67,125.7 -67,122.8 -67,119.9 -67,117 -67,117 -66.9,117 -66.8,117 -66.7,117 -66.6,117 -66.5,117 -66.4,117 -66.3,117 -66.2,117 -66.1,117 -66))"] | ["POINT(131.5 -66.5)"] | false | false |

Collaborative Research: Totten Glacier System and the Marine Record of Cryosphere - Ocean Dynamics |
An array of three moorings (M1-M3) with current meters, temperature, conductivity, and pressure (TCP) recorders were deployed along the eastern flank of the continental shelf off Sabrina Coast, at the main path of the Antarctic Coastal Current indicated by the uCTD data collected earlier during the cruise. These three US mooring were deployed at the 625-m (M1), 620-m (M2) and 1051-m (M3) isobaths. M1 was recovered on 25 February 2014, with a full data return from all of its instruments; whereas M2 and M3 were recovered in early 2015 on board of the Australian RVI Aurora Australis next year (cruise AU1402).
