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.
The first dives of the 2020 season commenced with dives to the French submarine Minerve in the Mediterranean Sea on 1–2 February 2020, and the second crewed descent to the Calypso Deep. [ 2 ] [ 3 ] On 10 February 2020 Victor Vescovo and Prince Albert II of Monaco reached the bottom of the Calypso Deep at a newly calculated depth of 5,109 m ...
The Mediterranean Sea (/ ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED-ih-tə-RAY-nee-ən) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border.
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.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
The Alboran Sea is the westernmost portion of the Mediterranean Sea, lying between the Iberian Peninsula and the north of Africa (Spain on the north and Morocco and Algeria on the south). The Strait of Gibraltar , which lies at the west end of the Alboran Sea, connects the Mediterranean with the Atlantic Ocean .
Ocean surface topography can be derived from ship-going measurements of temperature and salinity at depth. However, since 1992, a series of satellite altimetry missions, beginning with TOPEX/Poseidon and continued with Jason-1 , Ocean Surface Topography Mission on the Jason-2 satellite, Jason-3 and now Sentinel-6 Michael Freilich have measured ...
Tropical and subtropical seas, such as the Red Sea and the Mediterranean, can experience salinities as high as 40-41 ppt due to intense evaporation and restricted water exchange with the open ocean. Halocline: The halocline is a layer within the ocean where salinity changes rapidly with depth. This stratification can be influenced by surface ...
