World Ocean Bathymetry
#maps #oceans #bathymetry #depth
3800 metres is the average depth of the ocean, but it reaches 11,020 metres in the Mariana Trench in the northwestern part of the Pacific Ocean (coordinates 11° 21′ North Latitude and 142° 12′ East Longitude).
The GEBCO World Map shows the bathymetry of the world’s ocean floor in a shaded relief colour map. This version is an updated version of the 2013 world map (second version). It now includes the names of the underwater features.
Work to create the GEBCO global map began as a Nippon Foundation/GEBCO Training Project laboratory workshop at the Centre for Coastal and Ocean Mapping at the University of New Hampshire, USA.
The High Seas, an Undisclosed World
The high seas cover almost half of the world’s surface and 64% of the oceans. Most of the world is not owned by any nation and this unowned area is mainly aquatic.
Average ocean salinity
Finding an average of 34.7 grams of salt per litre of seawater is no mystery: since the dawn of time, the sea has been a large body of salt water!
Average ocean temperature
Oceanographers are constantly trying to measure temperature because it is an essential physical property of seawater.
We are the ocean planet
The Earth's surface covers more than 510 million square kilometres, but less than 30% of this surface is covered by land.
