Georges Bank is the most westward of the great Atlantic fishing banks. The now-submerged portions of the North American mainland are comprised in the continental shelf running from the Grand Banks of Newfoundland to Georges. Georges Bank was part of the North American mainland as recently as 12,000 years ago. [1]
A seafloor map captured by NASA. Bathymetry (/ b ə ˈ θ ɪ m ə t r i /; from Ancient Greek βαθύς (bathús) 'deep' and μέτρον (métron) 'measure') [1] [2] is the study of underwater depth of ocean floors (seabed topography), lake floors, or river floors.
Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward.
Map showing the Grand Banks. The Grand Banks of Newfoundland are a series of underwater plateaus south-east of the island of Newfoundland on the North American continental shelf. The Grand Banks are one of the world's richest fishing grounds, supporting Atlantic cod, swordfish, haddock and capelin, as well as shellfish, seabirds and sea mammals.
The Nippon Foundation-GEBCO Seabed 2030 Project, which aims to motivate a number of collaborators to create a full map of the ocean floor, was launched in 2016. [5] There are four Seabed 2030 centres, which coordinate mapping activities in different regions, gather and compile the bathymetric information, and partner with existing mapping ...
Map showing the Flemish Cap at far right. The Flemish Cap is an area of shallow waters in the north Atlantic Ocean centered roughly at 47° north, 45° west or about 563 km (350 miles) east of St. John's, Newfoundland and Labrador. The shallow water is caused by a wide underwater plateau covering an extended area of 42,000 km 2 (12,000 square ...
Generic Mapping Tools (GMT) are an open-source collection of computer software tools for processing and displaying xy and xyz datasets, including rasterization, filtering and other image processing operations, and various kinds of map projections. The software stores 2-D grids as COARDS-compliant netCDF files and comes with a comprehensive ...
