Scientists are combining data from water samples containing fish DNA with satellite data to find native fish and identify their habitats.
Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.
A new study reports a net increase of 5.38 petagrams of forest biomass between 1984 and 2016; carbon-wise, that is equivalent to a train of loaded coal cars long enough to wrap itself around Earth nearly 34 times.
Satellite images are helping to reveal how COVID-19 lockdown measures are impacting food security, urban surface heat, water quality and aquatic ecosystems, and more in NASA-funded studies.
Landsat and ICESat-2 satellite data have made it possible for scientists to develop maps showing the “quality” of tropical forests.
Using Landsat, researchers have created the first map of the causes of change in global mangrove habitats between 2000 and 2016—a valuable tool to aid conservation efforts for these vital coastline defenders.
LANDFIRE has released its Remap dataset; new techniques and new data provide significant improvement.
Goldberg will launch Cloud to Classroom, an innovative project that uses satellite imagery to help K-12 classrooms understand global environmental change through remote sensing.

Coastal ecosystems are some of Earth’s most biologically diverse environments, especially coastal mangrove forests. Dr. Lagomasino uses Earth observing data to study these vital biomes.
NASA has funded four projects to create new, virtual portals to share a wealth of biodiversity information with land stewards around the world.
Dr. Eric Bullock uses Earth observation data to explore the consequences of land use and land cover change in high biodiversity areas.
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.
Landsat data (since 1972) is helping scientists Sean Healey and Zhiqiang Yang of the Rocky Mountain Research Station (U.S. Forest Service) study the long-term impact of the May 18, 1980, eruption of Mount St. Helens.
This bird’s-eye view of the relationship between temperature and bird biodiversity will help conservationists figure out where to prioritize their efforts in a warming world.
Researchers and conservationists around the world are using data and images from NASA satellite instruments to manage and track living creatures of all kinds.
Kelp forest cover near Tierra del Fuego appeared to follow approximately four-year cycles that mirror sea surface temperature and El Niño-Southern Oscillation rainfall patterns.

Landsat imagery shows that bull kelp canopy area can vary dramatically from year to year, and that long-term population trends vary from reef to reef.
Intertidal wetlands significantly contribute to China’s environmental and ecological diversity, but are facing unprecedented pressures from anthropogenic development, as well as the threat of future sea level rise.
