This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water-leaving radiance (units of watts per square meter per steradian per nanometer) to downwelling irradiance (units of watts per square meter per nanometer) multiplied by π. This is also known as remote sensing reflectance (units of per steradian) multiplied by π. These data are intended for use in remote sensing of water color and differ...

Rural communities near large, protected areas like National Parks often face heightened social vulnerability and environmental risks (e.g., flooding), which are expected to worsen with climate and land-use changes. Researchers supported by this Southeast CASC project will collaborate with stakeholders and communities in the Southern Appalachians and Congaree to refine strategies for addressing these combined vulnerabilities. They will create maps and projections outlining high-risk areas that can be used by conservation managers and policymakers to prioritize management actions benefiting both the environment and human communities. People living near large, protected areas, such as National Parks, face a complex...

Epidemiological and toxicological studies have associated disinfection byproducts in drinking water with adverse public health outcomes. Disinfection byproducts can form when disinfectants such as chlorine combine with naturally occurring organic molecules dissolved in water. Anthropogenic factors that alter water quality, such as land use practices and wastewater production, can also influence disinfection byproduct occurrence. This project will assess and monitor the sources of disinfection byproduct precursors within the 6 primary drinking water source watersheds in the West-of-Hudson reservoir watersheds of New York City's drinking water supply. Through field observations, laboratory analysis, and data synthesis,...

The development of large-scale solar energy production facilities is a priority for renewable energy production in part due to the flexibility of suitable locations and wide range of compatible land types. Understanding the factors influencing carbon stocks during and after land use conversion is important because land use change can increase or decrease carbon stocks. Carbon stored in soils typically represents a significant carbon stock for ecosystems in New York State. This project estimates soil carbon stocks present within lands currently used for utility-scale (> 1 megawatt) photovoltaic solar energy production in New York State. The primary objectives are to estimate soil carbon stock changes associated with...

State and federal agencies are negotiating long-term water-supply agreements for the Colorado River basin, but current policies prioritize water supply over ecological factors due to limited knowledge about how water storage strategies impact ecosystems. Researchers supported by this Southwest CASC project will develop a tool to evaluate river ecosystem outcomes of various patterns of water consumption and reservoir operations, identifying management strategies that can help future policies balance water needs and ecological resources like native fish communities and natural flow patterns. State and federal agencies are negotiating water-supply agreements to govern the Colorado River basin’s water supply and...

This is a dataset summarizing filtering criteria and rapid risk assessments for ~25,000 species undertaken during a data-driven horizon scan of imported fish, amphibians, reptiles, birds, and mammals. The files represented in this dataset are the following: 1) 'species_filtering_metadata_table.xlsx' is the tabular summary of all intake list species names and the reason for inclusion/exclusion. 2) 'review_scores.xlsx' is the tabular summary of taxa expert risk assessment scores for species included after filtering. These data will be relayed to the U.S. Fish & Wildlife Service for further assessment and prioritization related to import regulation.

Many insect pollinator species in the southeastern US and the US Caribbean, including bees and butterflies, face increasing threats from climate change, but few have been assessed for their vulnerability to these threats. This leaves wildlife managers without crucial information for conservation planning. Researchers supported by this Southeast CASC project will work with partners to identify and evaluate the climate change vulnerabilities of at-risk pollinator species, and resulting species assessments will be provided to wildlife managers to use for conservation decision making. Many insect pollinators, including bee and butterfly species, play a vital role in ecosystems but face increasing threats form climate...

This Data Release includes information to support the characterization of surface/near-surface infiltration rates of selected landslide source area materials following Hurricane Maria across Puerto Rico, USA. The dataset includes comma-delimited measurements of field-saturated hydraulic conductivity (Kfs) collected over two field campaigns (Fall 2018 and Spring 2019) as well as laboratory-derived measurements of soil/saprolite texture. The Kfs experiments were conducted within (or in the vicinity of) landslide source areas across the three primary geologic terranes on the island (Bawiec, 1998), including intrusive, volcaniclastic, and submarine basalt/chert lithologies. Depending on site conditions and the hydrologic...

The water balance equivalence (WABE) method for reducing biases from remote sensing-derived evapotranspiration (RSET) products for large area applications is proposed and implemented across eight-digit hydrologic unit code (HUC8) basins in the conterminous United States (CONUS). These data support the findings of the WABE method that includes climatology (2002-2015 average) observed water balance ET (WBET), synthetic WBET, and bias adjustment factor (BAF) for SSEBop ET for HUC8 basins. The synthetic WBET filled the spatial gaps of observed WBET, constituting 44% of CONUS HUC8 basins, with estimations within 2% at the CONUS and between 1-12% across 18 regions in CONUS. After implementing HUC8-scale bias adjustment...
