Seafloor bathymetry of Sheldon Cove, Börgen Bay and Marian Cove, merged and gridded from EM122 multibeam echosounder data collected for the project NE/P003087/1 (2017-2020)
We present three new gridded bathymetric compilations of Sheldon Cove, Borgen Bay and Marian Cove.
These bathymetry grids were compiled from EM122 multibeam swath bathymetry data acquired during three different cruises (RRS James Clark Ross JR17001, JR18003 and JR19002 cruises also known as NERC- ICEBERGS cruises) from 2017 to 2020. The data is available as grids of 5 m resolution in NetCDF and GeoTIFF formats using geographic coordinates on the WGS84 datum.
This grid was compiled as part of the ICEBERGS (Impacts of deglaciation on bentic marine ecosystems in Antarctica) project.
Funding was provided by the NERC grant NE/P003087/1.

Methodology:
Bathymetric data was collected using a hull-mounted 1° x 1° EM122 Multibeam Echo Sounder (MBES). The EM122 equipment was operated using Kongsberg Seafloor Information System (SIS) and Helmsman software. Where possible, data were collected in a systematic manner with survey lines running parallel along depth contours to achieve consistent swath coverage and maximise insonification of slope areas. Sound velocity profiles (SVPs) were generated from CTD casts and applied during data acquisition.
Additional information about the data acquisition can be found in the cruise reports.
The data processing was performed using the QPS Qimera software.
Tide gauges used:
Station| IOC ID |Type |Logging Interval
Roth (Sheldon Cove) | ID: 342 |Radar |1 min
Vern (Börgen Bay)| ID: 188 | Pressure|1 min
Prat3 (Marian Cove) | ID: 189 | Pressure / Radar| 1 min
Tide gauge data: http://www.ioc-sealevelmonitoring.org/
Coordinates are in WGS84 UTM projected coordinates:
Sheldon Cove:19 S
Börgen Bay:20 S
Marian Cove:21 S
Data collection:
Data were collected as part of the following RRS James Clark Ross cruises:
- JR17001 in 2017
- JR18003 in 2018
- JR19002 in 2020
Data quality:
Data processing was performed in QPS Qimera software using observed tide from local tide stations. Gross errors were removed manually prior to each dataset being processed individually using filters and additional manual editing in problem areas. Total Propagated Uncertainty and data density were checked prior to merging successive years into the final product. Depths relate to mean depth of all surveys and refer to chart datum at each respective tide gauge. Data is NOT TO BE USED FOR NAVIGATION.
