Over geologic time sea level has fluctuated by more than 300 metres, possibly more than 400 metres. The main reasons for sea level fluctuations in the last 15 million years are the Antarctic ice sheet and Antarctic post-glacial rebound during warm periods. The current sea level is about 130 metres higher than the historical minimum.
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
The National Oceanographic Data Center, National Coastal Data Development Center (NCDDC) and NOAA Central Library, with its regional branch assets, were integrated to provide access to the world's most comprehensive sources of marine environmental data and information.
A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. [1] The term above sea level generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today.
The WOA consists of a climatology of fields of in situ ocean properties for the World Ocean. It was first produced in 1994 [ 2 ] (based on the earlier Climatological Atlas of the World Ocean , 1982 [ 3 ] ), with later editions at roughly four year intervals in 1998, 2001, 2005, 2009, 2013, 2018, and 2023.
The maps of North America (1796) and Scotland (1807) are the most celebrated of his many later productions. [2] In 1804, 63 maps drawn by Arrowsmith and Samuel Lewis of Philadelphia (publisher of William Clark's manuscript map of the Northwest) [3] were published in the New and elegant General Atlas Comprising all Discoveries to the Present Time.
Sea surface height change from 1992 to 2019: Blue regions are where sea level has gone down, and orange/red regions are where sea level has risen (the visualization is based on satellite data). [ 2 ] Between 1901 and 2018, the average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s.
Jason-3 is a satellite altimeter created by a partnership of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and National Aeronautic and Space Administration (), and is an international cooperative mission in which National Oceanic and Atmospheric Administration (NOAA) is partnering with the Centre National d'Études Spatiales (CNES, French space agency).
