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.
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 ...
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.

A portolan nautical chart of the Mediterranean Sea, second quarter of the 14th century. Kept in the Library of Congress , where it is the oldest original cartographic artifact. Portolan charts are nautical charts , first made in the 13th century in the Mediterranean basin and later expanded to include other regions.
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).
