Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) is a 2020s NASA Earth-observing satellite mission to observe global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds. [3] PACE is intended to be used to identify the extent and duration of phytoplankton blooms and improve understanding of air quality. [4]
The ocean temperature varies from place to place. Temperatures are higher near the equator and lower at the poles. As a result, changes in total ocean heat content best illustrate ocean warming. When compared to 1969–1993, heat uptake has increased between 1993 and 2017. [5]: 457
Data from NASA'S newest Earth-observing satellite will provide insight into ocean health, air quality, and the effects of a changing climate.
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 ocean is absorbing approximately 90 per cent of the heat trapped by greenhouse gases
The objectives of the mission are to make the first global survey of the Earth's surface water, to observe the fine details of the ocean surface topography, and to measure how terrestrial surface water bodies change over time. While past satellite missions like the Jason series altimeters (TOPEX/Poseidon, Jason-1, Jason-2, Jason-3) have ...
The global average covers 97-98% of Earth's surface, excluding only latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT, some areas with land above 1500 m altitude. The hemispheric averages are over the northern and southern hemispheres 0 to +/-85 degrees. The gridded data provide an almost global temperature map. [3]
TOPEX/Poseidon was a joint satellite altimeter mission between NASA, the U.S. space agency; and CNES, the French space agency, to map ocean surface topography.Launched on August 10, 1992, it was the first major oceanographic research satellite.
