The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
Map showing bathymetry in the South Atlantic Bight. The South Atlantic Bight is a bight in the United States coastline extending from Cape Hatteras, North Carolina to the Upper Florida Keys. [1] The Bight forms the western boundary of the Sargasso Sea and the Gulf Stream ocean current
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
IBCSO version 2 was published in 2022 [5] and increased the extent of the bathymetric map to 50°S, increasing the area covered by 2.5 compared to IBCSO version 1. 92.7% of map data originate from multibeam data, 6.7% originate from singlebeam data, and the remaining ~1% comes from mixed sources (seismic reflection, lidar, etc.).
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [26] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
Depths which have been measured are indicated by the numbers shown on the chart. Depths on charts published in most parts of the world use metres. Older charts, as well as those published by the United States government, may use feet or fathoms. Depth contour lines show the shape of underwater relief. Coloured areas of the sea emphasise shallow ...
Geologically, an ocean is an area of oceanic crust covered by water. Oceanic crust is the thin layer of solidified volcanic basalt that covers the Earth's mantle. Continental crust is thicker but less dense. From this perspective, the Earth has three oceans: the World Ocean, the Caspian Sea, [citation needed] and the Black Sea.
The Straits of Florida The Florida straits, the J-shaped channel between southeastern Florida and the Bahamas, and the Florida Keys and Cuba.. The Straits of Florida, Florida Straits, or Florida Strait (Spanish: Estrecho de Florida) is a strait located south-southeast of the North American mainland, generally accepted to be between the Gulf of Mexico and the Atlantic Ocean, and between the ...
