![]() 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.Visualize physical oceanography data products for near real-time monitoring of critical ocean parameters and decision support.“It allows users to get a quick look at the data very easily, while also enabling exploratory analysis.” “SOTO is a web-based user interface that allows you to visualize various scientific data products, with a focus on oceanographic-related datasets,” said Frank Greguska, a PO.DAAC scientific applications software engineer and the SOTO development lead. The easiest way to do this is to visit the State of the Ocean ( SOTO) online tool.ĭeveloped by NASA’s Physical Oceanography Distributed Active Archive Center ( PO.DAAC) and powered by NASA Worldview, SOTO provides access to a broad range of satellite-derived, ocean-focused data products and facilitates scientific oceanographic, climate, and related research. How out of the ordinary are such ocean temperatures? To find out, you’d need to look at sea surface temperature anomaly data, which show the difference between current temperatures and the long-term average. On Sunday, July 16, 2023, sea surface temperatures around Florida “ reached the highest levels on record,” with readings in some areas as high as 97✯. Gray, yellow, and green colors indicate little to no difference purple (cooler) and red (warmer) colors indicate greater differences. ![]() Colors in the image do not indicate surface temperature, but rather the difference between the current sea surface temperature and the long-term average. This image from PO.DAAC’s State of the Ocean shows a visualization of sea surface temperature anomaly data for the waters around Florida on July 16, 2023. ![]()
