Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Diet Data from Fecal DNA Metabarcoding and Video Camera Collars from the Porcupine Caribou Herd, Alaska and Yukon Diet Data from Fecal DNA Metabarcoding and Video Camera Collars from the Porcupine Caribou Herd, Alaska and Yukon
These diet data were collected from the Porcupine caribou herd in northern Alaska and Yukon in summer 2021 during 4 periods: calving (occasion 1), post-calving (occasion 2), mosquito harassment (occasion 3), and mid-summer (occasion 4). Diet data was determined by two distinct techniques: DNA metabarcoding data from fecal pellets and video data from camera collars deployed on adult...
Streamgage Attributes, Basin Characteristics, Subsidies from Glacier Mass Loss, and Streamflow Statistics, Selected Streamgages in Alaska, 2000-2019 Streamgage Attributes, Basin Characteristics, Subsidies from Glacier Mass Loss, and Streamflow Statistics, Selected Streamgages in Alaska, 2000-2019
This data package contains 3 tables presenting site selection information, basin characteristics, subsidy to streamflow from glacier mass loss data, and other streamflow statistics for selected streamgages in Alaska that were used to evaluate the influence of glacier mass loss on streamflow in Alaska and conterminous basins in Canada. The first ("site_selection_outcomes.csv") contains...
Wetland transformations for three relative sea-level rise scenarios along the middle and upper Texas Coast, wetland current condition map and wetland transformation maps by decade, sea-level rise scenario, and coastal wetland drowning threshold (ver. 2.0, Wetland transformations for three relative sea-level rise scenarios along the middle and upper Texas Coast, wetland current condition map and wetland transformation maps by decade, sea-level rise scenario, and coastal wetland drowning threshold (ver. 2.0,
As sea levels rise, wetlands exposed to oceanic water can adapt to changing conditions through vertical development (i.e., soil surface elevation gains via biophysical feedbacks) and horizontal migration into upslope areas. Elevation-based models of wetland transformation from sea-level rise are often hampered from a variety of sources of uncertainty, including contemporary elevation and...
Multisource Discrete Chlorophyll Data in the Illinois River Basin, 1976–2023 Multisource Discrete Chlorophyll Data in the Illinois River Basin, 1976–2023
This data release contains discrete chlorophyll data, specifically corrected chlorophyll a, uncorrected chlorophyll a, and pheophytin pigments, from inland waters in the Illinois River Basin for 1981–2023. These data are discrete samples (collected in the field and analyzed in the laboratory) of plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, canals...
Long-term change on barrier islands and barrier shorelines from extreme storms and restoration along the north central Gulf of Mexico coast Long-term change on barrier islands and barrier shorelines from extreme storms and restoration along the north central Gulf of Mexico coast
These data utilize existing land cover products and elevation information to provide information on changes on barrier islands and barrier shorelines along the north central Gulf of Mexico coast. Specifically, this data release includes information on changes in subaerial land, habitat types, and high-tide flooding for barrier islands and barrier shorelines along the north central Gulf...
Species of Greatest Conservation Need National Database 2005-2022 Species of Greatest Conservation Need National Database 2005-2022
The Species of Greatest Conservation Need National Database is an aggregation of lists from State Wildlife Action Plans. Species of Greatest Conservation Need (SGCN) are wildlife species that need conservation attention as listed in action plans. In this database, we have validated scientific names from original documents against taxonomic authorities to increase consistency among names...
