Using NASA Earth Observations to Determine the Extent of Drought and Insect-related Dieback in Oak Woodlands within the Santa Monica Mountains, California

The Santa Monica Mountains stretch along the west coast of California between the coastal city of Oxnard and the populous urban hub of Los Angeles. Despite the close urban proximity, the Santa Monica Mountains still retain 80% native vegetation cover, including precious expanses of...

GPM IMERG precipitation, NLCD Landuse, STATSGO soil, and SRTM DEM data were processed in ArcSWAT to model  annual sediment loads in the Weeks Bay watershed sub basins.

Weeks Bay is an estuarine system located along the southeastern shore of Mobile Bay in Baldwin County, Alabama. Its watershed encompasses approximately 149,000 acres of mixed-use land around the Fish and Magnolia Rivers. Weeks Bay and the surrounding coastal lands...

Using NASA Earth Observations to Evaluate Water Quality in Coastal Alabama to Enhance Marine Wildlife Management

The Mobile Bay and Mississippi Sound are the main coastal estuaries along the Alabama and Mississippi Gulf Coast. They serve as the primary drainage outlets for the Mobile Bay and Pascagoula River watersheds and provide a gradient of coastal water salinity conditions needed for a...

Using NASA Earth Observations to Identify Current Habitat Areas and Forecast Habitat Suitability for the Yellow-Billed Cuckoo in Semiarid Environments.

Observations of the threatened western yellow-billed cuckoo (YBC) are rare in Idaho, Wyoming, and Utah. This species can act as an indicator for the overall health of an ecosystem, therefore understanding their habitat is critical to planning and improving land management and ecosystem conservation...

Imagery of turbidity captured by the NASA Landsat 8 Operational Land Imager on Dec 24, 2020. Pictured is the lower portion of the Texas Highland Lakes chain with the city of Austin, Texas to the right. Dark blue corresponds to low, green to medium, and orange and red to high turbidity levels. Monitoring turbidity can aid in the understanding of algal event development throughout the Highland Lakes chain.  Keywords: Highland Lakes, Colorado River, Texas Hill Country, Austin, Lake Travis, Lady Bird Lake, Lake Austin, Lake LBJ, Lake Marble Falls, Landsat 8 OLI

Beginning in 2019, harmful algal events in Austin, Texas, caused canine deaths in the Lady Bird Lake and Lake Travis reservoirs. These reservoirs are part of the larger Highland Lakes chain, managed by the Lower Colorado River Authority (LCRA) and...

Composited Landsat 8 imagery from March - May 2020 with a false color band combination (5, 4, 3). Dark red represents dense vegetation while light red represents less dense vegetation. Open water masks were applied to ALOS-PALSAR-1 images to delineate the water body extent of Laguna Seca in Belize between June 2008 (light blue) and after Tropical Depression 16 in October 2008 (dark blue). Environmental departments can make informed management decisions by monitoring flood-prone areas.  Keywords: Kat Tafoya, ALOS PALSAR 1, Landsat 7, seasonal inundation, forest canopy, wetlands, L-band SAR

As climate change increases the severity and frequency of extreme weather events in the tropics, it is vital for the safety of local communities and the health of ecosystems to monitor seasonal inundation. Forested inundation affects the ability of forested...

Using NASA Earth Observations to Map Winter Cover Crop Conservation Performance in the Chesapeake Bay Watershed

Winter cover crops are an essential component of adaptive management practices to reduce soil erosion, nutrient loss, and nutrient leaching leading to water quality degradation. The Maryland Department of Agriculture (MDA) and Chesapeake Bay partners (US Geological Survey and USDA Agricultural Research Service) oversee...

Turbidity processed imagery using 2020 Landsat 8 OLI/TIRS data. The Chandeleur Islands located on the southeastern coast of Louisiana are displayed. Shades of yellow indicate areas with high turbidity and darker shades of blue indicate areas with low turbidity. Concentrating on areas with higher turbidity allows the coastal restoration experts to know where land erosion occurs and identify ideal areas for seagrass revegetation.  Keywords: Water Resources, Turbidity, Seagrass, Breton National Wildlife Refuge (BNWR), Chandeleur Islands, Louisiana

The barrier islands of Louisiana’s Breton National Wildlife Refuge (BNWR) are disappearing due to sea level rise, extreme hurricanes, sediment starvation, and the Deepwater Horizon oil spill. This decline in land area has damaged important bird habitat and reduced the...

Using NASA Earth Observations to Monitor Land-use Change and Map At-risk Coastal Habitats in the U.S. Virgin Islands

The United States Virgin Islands (USVI) are home to an array of diverse and stunning habitats. The beauty of the islands has continued to attract visitors and residents, which overtime has increased human development and impact. The resulting land-use change increases sediment loads and the...

Slopes of post-fire median NDVI recovery derived from post-fire annual composites between 2002 and 2019 of harmonized Landsat 5 TM, 7 ETM, and 8 OLI satellites for the historic Hayman Fire that burned more than 130,000 acres of Colorado’s Front Range forest is pictured here. NDVI in burned areas that are recovering relatively quickly, moderately and slowly are shown in dark blue, green, and yellow, respectively.   Keywords: remote sensing, Landsat 8 OLI, Landsat 7 ETM, Landsat 5 TM, wildfire, vegetation recovery, Random Forest​

Forest composition and structure in the Colorado Front Range has been altered by changing wildfire regimes. In particular, increased moderate- and high-severity fire significantly reduces forest cover following fire and often results in reduced seedling regeneration. Reduced tree canopy regrowth...
