Raw data from Ran AUV missions ANA14B_01, ANA14B_02 and ANA14B_03 performed during the ANA14B RVIB Araon expedition to the Amundsen Sea
Raw data from AUV missions ANA14B_01, ANA14B_02 and ANA14B_03 from the RVIB Araon expedition ANA14B in Jan - Feb 2024.
The following data set contains the raw data from the first three AUV missions that were conducted during the ANA14B expedition to Thwaites glacier in 2024. The missions were conducted following the seabed at altitude 50 - 90 m. The raw data contains the complete data sets and are not post processed regarding navigation, calibration of the sensors, or gridded. This data set will be connected to the updated post processed and gridded files when these become available.
The folder tree is described in the document folder_tree.pdf.
The contents of the zip-files are listed in the documentation files ANA14B_01.filelist.txt, ANA14B_02.filelist.txt and ANA14B_03.filelist.txt, and the SHA-256 checksums are contained in sha256sums.txt.

- Supplemental Information
- The dataset was produced with support from the OCEAN:ICE project – Ocean-Cryosphere Exchanges in ANtarctica: Impacts on Climate and the Earth System, funded under Horizon Europe, Grant Agreement No. 101060452. The dataset contains raw observations from the ANA14B_01, ANA14B_02 and ANA14B_03 Ran AUV missions and has not been corrected or post-processed with respect to navigation, sensor calibration or gridding. Post-processed data are expected to complement this dataset.

- Statement
- The dataset contains raw observations acquired during the first three Ran Autonomous Underwater Vehicle (AUV) missions, ANA14B_01, ANA14B_02 and ANA14B_03, performed during the ANA14B RVIB Araon expedition to the Amundsen Sea, West Antarctica, between 7 and 17 January 2024. The missions were conducted close to the seabed, at approximately 50–90 m above the bottom, and partly beneath Thwaites Glacier. The dataset represents the complete raw observations acquired during these missions. The data have not been corrected or post-processed with respect to navigation, sensor calibration or gridding. File organisation and contents are documented through the accompanying folder tree, file descriptions and mission-specific file inventories, and SHA-256 checksums are provided for integrity verification.
