Ecosystems. An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network ...
Our data products useful to the study of human-influenced ecosystems include crop extent maps, urban greenhouse gas measurements, and land cover surveys. These data enable important studies into how humans shape the Earth and how we can better care for our planet. Access a range of datasets and data tools to further your research into ...
Wetlands are a type of terrain where the land is permanently or seasonally saturated with water. Swamps and marshes are types of wetlands. Insects, waterfowl, fish, amphibians, and other animals often find a home in wetlands, creating a complex ecosystem that combines land-based and aquatic life. Wetlands help stabilize shorelines and provide a ...
The Global Ecosystem Dynamics Investigation (GEDI) aims to characterize the effects of changing climate and land use on Earth. Specifically, GEDI helps researchers study ecosystem structure and dynamics to enable radically improved quantification and understanding of Earth's carbon cycle and biodiversity. From its vantage point on the ...
NASA biosphere data are critical for understanding Earth's species diversity, climate regulation and change, and its ecosystem processes. Life within Earth’s biosphere consists of millions of species living in various types of biomes such as grassland, forest, desert, aquatic, and tundra areas. Biomes are often divided into numerous subtypes ...
The Global Ecosystem Dynamics Investigation (GEDI) instrument is a full-waveform lidar installed on the International Space Station that produces detailed observations of the 3D structure of Earth’s surface. GEDI's three lasers precisely measure forest canopy height, canopy vertical structure, and surface elevation.
The newly released Level 4B (L4B) Gridded Aboveground Biomass Density dataset from NASA’s Global Ecosystem Dynamics Investigation mission provides that foundation by providing near-global estimates of aboveground biomass density (AGBD) in megagrams per hectare (Mg/ha) at a 1-kilometer (km) resolution between 51.6° North and 51.6° South latitudes.
Laura Naranjo. If a tree falls in the Amazon rainforest, biologist William Laurance just might hear it. And as human activity encroaches on the forests, Laurance is finding that a lot of trees are falling. As people penetrate the Amazon interior, they build roads and clear large expanses of land. Over time, this process of deforestation creates ...
Credit: NASA's Goddard Space Flight Center. When NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite launched into space on February 8, 2024, the team was excited for the spacecraft to begin its mission. This is not only because the endeavor was more than a decade in the making and critical for understanding Earth's ocean ...
The ctenophores arrived in the ballast waters of ships, transported from their native environment off the east coasts of North and South America. Once in the Black Sea, the ravenous population quickly increased and spread, feasting on plankton, fish eggs, and fish larvae. Without a natural predator to halt its expansion, the ctenophore’s ...
