Ecosystems | NASA Earthdata
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 ...
Anthropogenic/Human Influenced Ecosystems | NASA Earthdata
Anthropogenic/Human Influenced Ecosystems. NASA’s Earth science data show the impact of humans on the planet through studying factors like nighttime lights, land cover, and agriculture. There are many causes of biodiversity loss, including deforestation, agricultural development, urbanization, pollution, and climate change.
Wetlands | NASA Earthdata
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 ...
GEDI | NASA Earthdata
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 ...
Biosphere | Earthdata - NASA
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 ...
GEDI Lidar | NASA Earthdata
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.
ORNL DAAC Releases GEDI Level 4B Dataset Offering Gridded …
May 19, 2022 · 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.
Preparing for PACE Data | NASA Earthdata
Feb 28, 2024 · 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 ...
Invasion of the Ctenophores | NASA Earthdata
Dec 28, 2020 · 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 ...
Where the Wetlands Are | NASA Earthdata
Dec 28, 2020 · Wetlands are places where land is permanently or seasonally saturated with water, forming a distinct ecosystem that is both aquatic and land-based. Although wetlands may exist wherever water collects, they often border rivers and lakes, creating spongy coastlines astir with fish, birds, and the drone of mosquitoes and dragonflies.
