The Jason-2/Ocean Surface Topography Mission (OSTM), the third in a U.S.-European series of satellite missions designed to measure sea surface height, successfully ended its science mission on Oct. 1. NASA and its mission partners made the decision to end the mission after detecting deterioration in the spacecraft's power system.

The Salinity Processes in the Upper Ocean Regional Study (SPURS) project is a NASA-funded oceanographic campaign aimed at elucidating key mechanisms responsible for near-surface salinity variations in the ocean. Over the period August 2016 through November 2017, SPURS-2 deployed a suite of in situ sampling technologies to study a low-salinity, high precipitation region in the eastern tropical Pacific, including the state-of-the-art wind and solar powered unmanned surface vehicle (USV) called Saildrone.

Oceans Melting Greenland (OMG) is a NASA Earth Venture Suborbital (EVS-2) mission that aims to improve estimates of sea level rise by addressing the question: To what extent are the oceans melting Greenland’s ice from below? OMG observes changing water temperatures on the continental shelf surrounding Greenland, and how marine glaciers react to the presence of warm, salty Atlantic Water. The complicated geometry of the sea floor steers currents on the shelf and often determines whether Atlantic Water can reach into the long narrow fjords and interact with the coastal glaciers. Because knowledge of these pathways is a critical component of understanding the interaction between the oceans and ice sheet, OMG facilitates improved measurements of the shape and depth of the sea floor in key regions.
OMG uses airborne, in situ, and ship-based observations to provide a revolutionary dataset for understanding ocean/ice interactions to improve estimates of global sea level rise. Please see the OMG website and PO.DAAC’s OMG mission webpage for more information on the OMG mission.
OMG mission datasets are archived and distributed by the PO.DAAC. At this time, the PO.DAAC is pleased to announce the public release of the Oceans Melting Greenland (OMG) Airborne eXpendable Conductivity Temperature Depth (AXCTD) Version 1 dataset. The dataset is described and discoverable via the PO.DAAC dataset information page. The dataset information pages also provide access to the technical documentation and guidance on how to cite the data.

Attention: PO.DAAC has retired all the NOAA AVHRR PATHFINDER SST v5.0 and v5.1 datasets. PO.DAAC will no longer support these datasets.
Interested users should access the NOAA NCEI website at: https://www.nodc.noaa.gov/SatelliteData/pathfinder4km/ for these datasets and more recent versions.
