Jorge Vazquez, a research scientist with NASA's Jet Propulsion Laboratory (JPL) in Southern California. Therefore, the coupling between these two parameters gave a strong reason for being able to visualize them jointly as data layers and for different regions of the world’s ocean,” said Dr. “From the science perspective, the relationship between SST and chlorophyll is an important one for understanding biodiversity. Powered by NASA Worldview, the State Of The Ocean (SOTO) tool from NASA's PO.DAAC allows users to visualize key ocean parameters through the use of gridded data, animations, and data comparisons and facilitates the discovery and analysis of oceanographic data products to enable scientific oceanographic, climate, and related research. When these currents flow near the surface, they are typically visible in sea surface imagery when not obscured by clouds. Sea surface temperatures are normally warmer near the equator and cooler near the poles, but ocean currents move warm and cold water around Earth’s oceans. These layers are critical to oceanographic research as changes in sea surface temperature impact weather, oceanic and atmospheric current patterns, ocean ecology, and even life on land. SOTO’s Sea Surface Temperature (SST) and Sea Surface Temperature Anomaly layers are created with data from the Group for High Resolution Sea Surface Temperature ( GHRSST) Multiscale Ultrahigh Resolution ( MUR) Level 4 Global Foundation Sea Surface Temperature Analysis (v4.1) product. In addition, chlorophyll features can also be used to trace oceanographic currents, atmospheric jets, upwelling and downwelling, and river plumes. The concentration of chlorophyll a is used as an index of phytoplankton biomass, and because changes in the amount of phytoplankton indicate the change in productivity of the ocean, it is a useful measure for assessing ocean health. Chlorophyll is a light-harvesting pigment found in most photosynthetic organisms in the ocean, phytoplankton all contain the chlorophyll pigment, which has a greenish color. The Chlorophyll a data layer, sourced from a Level 2 product created with data from the Moderate Resolution Imaging Spectroradiometer ( MODIS) instrument aboard NASA’s Aqua and Terra satellites, provides the near-surface concentration of chlorophyll a in milligrams of chlorophyll pigment per cubic meter (mg/m 3). SOTO’s visualizations of oceanographic satellite datasets center on three parameters: chlorophyll a, sea surface temperature, and sea surface temperature anomaly. Discover and analyze oceanographic data products to enable scientific oceanographic, climate, and related research.Access a broad range of satellite-derived products of interest to the oceanographic community (i.e., productivity, salinity, sea surface height) in NASA’s Earth Observing System Data and Information System (EOSDIS) archive.
