Arctic topography and bathymetry. Topography and bathymetry of the Arctic (based on the ETOPO5 data set)

Number of Authors: 3 2015 (English) In: Arctic, ISSN 0004-0843, E-ISSN 1923-1245, Vol. 68, p. 41-47 Article in journal (Refereed) Published Abstract [en] Most ocean science relies on a geospatial infrastructure that is built from bathymetry data collected from ships underway, archived, and converted into maps and digital grids.

The original international effort assembled all available Arctic bathymetric data and gridded them using a continuous curvature spline under tension at a resolution of 2.5 x 2.5 km to produce a Digital Bathymetric Model “Accurate bathymetry of the Arctic seafloor is key to maritime safety, economic development, and sustainability efforts in the region. 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. These models predict depth from remotely sensed lake color and are able to explain 58.5–97.6 % of depth variability.

Several campaigns to map seafloor bathymetry through ship soundings have been proposed, but only small fractions of the Arctic Ocean have ever been covered. 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). The existing bathymetry map of the Arctic is a compilation of ship soundings and digitized contours.

The goal of this initiative is to develop a digital data base that contains all available bathymetric data north of 64 degrees North, for use by mapmakers, researchers, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed. Bathymetry in the Gulf of Bothnia was derived from a compilation by Seifert and Kayser. Contours were extracted from the GEBCO Digital Atlas (GDA) [IOC, IHO, and BODC, 1997] to supplement the database in the southern Norwegian-Greenland Seas,inBaffinBay,andinsomeareasoftheCanadianArctic. The goal of the IBCAO initiative is to develop a digital data base that contains all available bathymetric data north of 64° North, for use by mapmakers, researchers, institutions, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed. Arctic Bathymetry Data Acquired from US Navy Sturgeon-Class Submarines The Arctic Ocean is the least known of all the ocean basins. The Arctic has been explored from ice islands, icebreakers, airplanes and satellites. Every survey has revealed more of the Arctic Ocean basin, but operated under the restrictions imposed by ice and weather.
