Research by our colleagues Jamie Morison at the University of Washington Seattle and NASA scientist Son Nghiem suggests that bathymetry (sea floor topography) plays an important role in Arctic sea ice formation and extent by controlling the distribution and mixing of warm and cold waters. The details of algorithm used for the development of Arctic bathymetry can be referred to the paper from Smith and Sandwell (1994). The assumedcorrelationinthe wavelengthbetweenthe downwardcontinued gravity and bathymetry is between 15 and 160 km. In the Arctic, there might be errors on the long wavelength components in the gravity. The International Bathymetric Chart of the Arctic Ocean (IBCAO) is an international project endorsed by the International Arctic Scientific Committee (IASC), the International Hydrographic Commission (IHO), and the Intergovernmental Oceanographic Commission (IOC). Bathymetry is the measurement of the depths of oceans, seas, or other large bodies of water.

This first Saildrone USV fleet will make high-resolution mapping of the Arctic cost-effective at scale while limiting risk to human health and safety in those remote regions,” said Saildrone CEO Richard Jenkins. Our knowledge of the depth and shape of the Arctic Ocean floor - its bathymetry - is insufficient. Owing to year-round sea-ice coverage and the cost of research in this remote region, much of the
Since 2018, the team has contributed to the 4.0 IBCAO map with data mainly obtained through the multibeam bathymetry in oceanographic campaigns in the Arctic, specially in the western area in the
Sonar depth point measurements collected at 17 lakes on the Arctic Coastal Plain of Alaska are used to train and validate models to map lake bathymetry.

Due to the presence of all-year sea ice, costly operations and political restrictions, dense and full coverage of the Arctic is not possible, leaving huge gaps between the existing surveys. 2015-12-01 · In 1997, the International Bathymetric Chart of the Arctic Ocean (IBCAO) project was initiated in St. Petersburg, Russia. The project's main objective was to collect all available bathymetry data for the compilation of the most up-to-date bathymetric portrayal of the Arctic Ocean seafloor (Macnab and Grikurov, 1997).

Several campaigns to map seafloor bathymetry through ship soundings have been proposed, but only small fractions of the Arctic Ocean have ever been covered. The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and international waters above the Arctic Circle (66 degrees 33 minutes North latitude). All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark (via Greenland), Finland, Iceland, Norway, Russia, Sweden ARCTIC VOL 36, NO.2 (JUNE 19831 P 121-142 Maps of the Arctic Basin Sea Floor: A History of Bathymetry and its Interpretation J.R.
