Saildrone Arctic Field Campaign

Colored line in image is the survey track of the joint NASA/NOAA Saildrone Arctic campaign within the Bering and Chukchi Seas to the ice edge and back over 150-days. Saildrone is a wind and solar powered unmanned surface vehicle (USV) capable of long-distance deployments lasting up to 12 months.

Sensing Sea Surface Salinity

Colors in image are sea surface salinity (SSS) measurements. Freshwater from the Yukon River (dark line in Alaska just below image center) into the Bering Sea is clearly seen as low salinity signatures (blue/dark blue) in the Saildrone track and Soil Moisture Active Passive (SMAP) SSS data.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.

Global Hackathon to use Earth Observing Data to Address COVID-19 Challenges

The NASA Space Apps COVID-19 Challenge invites global teams to use Earth observing data to find solutions to COVID-19 challenges over a 48-hour virtual hackathon May 30 to 31.

Sensing Invasive Species From Space

Invasive species cost the U.S. economy approximately $120 billion a year and disrupt the dynamics of ecosystems. Researchers are increasingly using remote sensing to map where invasive species are and where they could spread in order to minimize their damage.
