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.

An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Conterminous United States (1985-2023) An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Conterminous United States (1985-2023)
Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using readily available satellite imagery for the coastal areas of the contiguous United...
Importance of seed source selection when planting big sagebrush seedlings in a post-fire context: Assessment of subspecies, climate adaptation, and eco-physiological traits on early establishment Importance of seed source selection when planting big sagebrush seedlings in a post-fire context: Assessment of subspecies, climate adaptation, and eco-physiological traits on early establishment
This dataset contains information on seedling survival, physiochemical, morphological, and eco-physiological characteristics of seedlings grown and planted from seed collected from different sagebrush populations as well as the climatic conditions of those seed source sites in relation to the common garden location in which they were planted.
Caernarvon Freshwater Diversion (BS-0008): 1998 land-water classification Caernarvon Freshwater Diversion (BS-0008): 1998 land-water classification
The Louisiana Coastal Protection and Restoration Authority develop restoration plans in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set...

Passive integrated transponder tag data from the West Brook, MA, USA Passive integrated transponder tag data from the West Brook, MA, USA
The Ecology Section at the USGS Conte Laboratory has studied fish in the West Brook since 1997. The goal is to understand the strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish population dynamics for this stream network and ultimately individual fitness (natural selection and...
Juvenile coho salmon growth differences track biennial pink salmon spawning patterns Juvenile coho salmon growth differences track biennial pink salmon spawning patterns
Spawning salmon provide marine derived resources to freshwater ecosystems that can benefit stream-dwelling fish foraging and growth. Pink salmon are widely distributed throughout watersheds along the north pacific ocean, and display distinct biennial fluctuations in spawning abundance. These data were collected from a coastal watershed in northern southeast Alaska (Montana Creek) to...
Data from two bathymetric surveys of the Sandusky River near Bradys Island, Fremont, Ohio, March 2023 and May 2024. Data from two bathymetric surveys of the Sandusky River near Bradys Island, Fremont, Ohio, March 2023 and May 2024.
As part of the Great Lakes Restoration Initiative (GLRI) project template 774-GC10 entitled, “Characterization of hydrology and sediment mobility to inform design and implementation of a seasonal barrier to disrupt invasive grass carp reproduction in the Sandusky River near Brady’s Island, Ohio”, two bathymetric surveys of the Sandusky River from the Hayes Avenue bridge to the Ohio State...
Pesticide concentrations in water samples and quality-control samples collected at surface-water sites in Hawaiʻi, 2016–19 Pesticide concentrations in water samples and quality-control samples collected at surface-water sites in Hawaiʻi, 2016–19
This dataset contains pesticide-concentration values and other information for water samples and quality-control samples collected at surface-water sites on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi between November 2016 and June 2019. The water water samples and quality-control samples were collected for a study that assessed pesticides in surface water in Hawaiʻi, as...
Pesticide, organic-contaminant, and wastewater-indicator results for passive samplers deployed in surface water and groundwater in Hawaiʻi, 2015–19 Pesticide, organic-contaminant, and wastewater-indicator results for passive samplers deployed in surface water and groundwater in Hawaiʻi, 2015–19
The U.S. Geological Survey (USGS) deployed passive samplers at surface-water and groundwater sites on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi for several weeks each during 2015–19. The passive samplers were deployed to assess the occurrence of pesticides and pesticide degradates, herein referred to as pesticides, in water at the sites. Some of the passive samplers were...
Surface-water sites in Hawaiʻi where pesticides were assessed, 2015–19 Surface-water sites in Hawaiʻi where pesticides were assessed, 2015–19
This dataset includes information for the sample sites in Hawaiʻi where pesticides in surface water were assessed during 2015–19. The sample sites were distributed on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi. The site information is provided in two formats: a comma-separated-value (CSV) file and a shapefile formatted for use in a geospatial information system. A summary...
