Normalized Difference Water Index-processed imagery using 2017 Landsat 8 OLI data with modified true color bands. Black represents open water, light blue represents inundated vegetation, and pink represent upland areas. This image was taken of Selawik, AK, and can aid in identifying wetland inundation and extent. title=

Alaska’s wetlands make up over a third of the state’s land cover and provide numerous ecosystem services, such as water filtration and storage, nutrient retention, and habitat to a diverse range of plant and animal species. Temporal variations in wetland...

Spatial Modeling of the Fragmentation of Local Species Habitat from Increasing Urbanization in North Alabama

Alabama is one of the four most biodiverse states in the United States, and has greatest diversity of aquatic species of any state in the U.S. This biodiversity is at risk as urbanization increases in Alabama. The Land Trust of North Alabama works to preserve...

Synthesizing Temperature, Reflectance, and Land Change to Provide Spatial and Temporal Temperature Analyses in Richmond, Virginia

Cities around the world are adopting adaptation and mitigation strategies for extreme heat events, which are projected to increase in upcoming years. As Richmond, Virginia continues to grow, its residents are more likely to experience more extreme temperatures resulting from the urban heat island effect...

Synthesizing Trends in Water Quality Parameters Affecting Oyster Reef Health in the Mississippi Sound Using NASA Earth Observations

Commercially-harvested oysters are a significant ecological and economic driver in multiple coastal regions throughout the world. In the last decade, the Mississippi Sound has seen a rapid decline in oyster reef production, especially in the years following large ecological disturbances such as Hurricane Katrina...

Understanding Fuel Loading in Lassen Volcanic National Park Through Earth Observation to Manage Wildland Fire Risk

Nearly three quarters of Lassen Volcanic National Park (LVNP) is designated as Wilderness under the Wilderness Act of 1964, meaning it is to be managed "to preserve its natural conditions… with the imprint of man's work substantially unnoticeable." This prevents land managers from clearing excess...

DNBR-processed Sentinel-2 MSI image from 2020 with a June 2nd, 2020 and Landsat 8 OLI true color band combination (4,3,2), draped over a Shuttle Radar Topography Mission DEM. The northeast portion of the Cameron Peak Fire in Colorado is displayed. Green indicates areas with low burn severity and orange and red indicate moderate/high burn severity. DNBR maps can be used by stakeholders to identify areas of concern for future restoration and management efforts.  Keywords: Burn Severity, Forest Treatment, Forest Management, Wildfire

Along the Colorado Front Range, the importance of forest management has gained significant attention due to uncharacteristically intense fires that burned late in 2020. The Cameron Peak Fire, the largest in Colorado’s recorded history, and the CalWood Fire collectively burned an estimated...

Modified Normalized Difference Water Index (MNDWI)-processed imagery of Jobos Bay, Puerto Rico, using Landsat 8 OLI data from 2020. In order to detect shoreline change over time, MNDWI was used with thresholding techniques to classify water and land in the area from 1997 to 2020. Dark purple areas show water and yellow represents land. Classifying water and land over the study period allows partners to quantify change and potential impacts of sea level rise.  Keywords: Landsat, MNDWI

Jobos Bay is located on the southern coast of Puerto Rico, which is known for intense hurricane seasons and increased seasonal storm surge. Scientists at Jobos Bay National Estuarine Research Reserve (JBNERR) are concerned that sea level rise will exacerbate...

Blended image of a DEM from NASA’s SRTM, slope processed from the DEM, NLCD 2016 data, and a 2018 Soil Survey Geographic Database from the Natural Resources Conservation Service over the state of South Dakota, showing a section of the Rosebud Sioux Reservation Land. The dominant layer of DEM shows higher elevation in dark red and lower elevation in lighter red to yellow; all these layers help highlight the risk of flooding in this landscape.  Keywords: SRTM, DEM, NLCD, Soil Survey, South Dakota, Indigenous Peoples, Flood Mapping, Flood Risk

In 2019, the Great Plains experienced unprecedented catastrophic flooding. Large flood events are predicted to increase in frequency and severity, posing risks to communities in this region, particularly Tribal Nations. We used Sentinel-1 C-band Synthetic Aperture Radar (C-SAR), imagery from...

(1) Change in vegetation regrowth post-Silver Fire (2013) in Gila National Forest Watershed from 2013-2019 using NBR, calculated from Landsat-8 OLI imagery. Fire area delineated with warm-color scale, yellow and pink represent high and low vegetation regrowth respectively.  (2) NDWI calculated from 2019 Landsat-8 OLI image, emphasizing stream visualization underneath stream vector where dark blue represents high water content. This helps forest managers understand vegetation recovery and how burned areas interact with hydrology of the watershed.  Keywords: Gila National Forest, wildfire, watershed, hydrology, vegetation recovery, NBR, Landsat

Wildfires have the potential to cause devastating and long-lasting impacts on ecological systems. In the Gila National Forest (Gila NF), wildfire events have occurred with increasing frequency and severity over recent years. These disturbances, such as the historic Whitewater Baldy...
