The knowledge about bathymetry and ocean tides is at the crossroads of many scientific fields, especially in the Polar regions, as it has significant impact on ocean circulation modelling and the understanding of the coupled dynamical response of the ocean, sea ice and ice shelves system, the quality and accuracy of sea surface height and sea ice parameter estimates from satellite altimetry, or the understanding of ice-shelf dynamics, among others. In isolated regions such as the Southern Ocean, where very few in-situ campaigns are possible, satellite observations bring invaluable information, either directly, with the physical parameters that are measured, or indirectly, considering the strong links between particular characteristics of the parameters and the ocean processes.
The ALBATROSS project (ALtimetry for BAthymetry and Tide Retrievals for the Southern Ocean, Sea ice and ice Shelves), led by NOVELTIS in collaboration with DTU Space, NPI and UCL, is one of the activities funded by the European Space Agency in the frame of the Polar Science Cluster, with the objective to foster collaborative research and interdisciplinary networking actions.
ALBATROSS is a 2-year project that started in mid-2021 with several objectives: first, to improve the knowledge on bathymetry around Antarctica, considering decade-long most recently reprocessed CryoSat-2 datasets, innovative information on bathymetry gradient location through the analysis of sea ice surface roughness characteristics, and the compilation of the best available datasets in ice-shelf regions; second, to improve the knowledge on ocean tides in the Southern Ocean through the implementation of a high-resolution hydrodynamic model based on the most advanced developments in terms of ocean tide modelling, and data assimilation of observations, including satellite-altimetry derived tidal retrievals from the most recent and relevant satellite altimetry products to fill the gap between the 66°S-limited coverage of the Topex-Jason suite missions and the Antarctica coast.
This paper presents the most recent results obtained within the ALBATROSS project.
