This dataset consists of raster geotiff outputs from modeling vertical accretion and carbon accumulation in the Nisqually River Delta, Washington, USA. These rasters represent projections of future habitat type, change in surface elevation above Mean Sea Level, and total sediment carbon accumulation since 2011 in coastal wetland habitats. Projections were generated in 20-year increments for 100 years for five amounts of sea-level rise, three amounts of suspended sediment concentrations, and two alternative configurations of the U.S. Interstate-5 causeway as it crosses the Nisqually River to either prevent or allow inland habitat migration (a total of 30 scenarios). The full methods and results are described in detail...
In response to the rapidly evolving conditions at the Salton Sea with the emergence of both newly formed wetland habitat and increasing hazards to wildlife, the U.S. Bureau of Reclamation and U.S. Geological Survey have funded a re-evaluation of data gaps regarding selenium concentrations in biota the region. As part of this work, selenium concentrations in biological tissue samples were compiled from published reports, public databases, and unpublished archives into a tabulated spreadsheet. Since the California Department of Water Resources summarized selenium biological data in 2005, our compilation efforts focused on the 2005 through 2020 range. The resulting dataset encompasses all records available to us from...

This datasets summarizes small mammal trapping efforts that USGS San Francisco Bay Estuary Field Station has led, co-led, or supervised, to detect and monitor the endangered salt marsh harvest mouse (Reithrodontomys raviventris) in the northern reaches of San Francisco Bay from 1998-2014. As the salt marsh harvest mouse is listed as endangered under the Endangered Species Act, sensitive location information can be made available upon request by contacting the dataset point of contact. These data support the following publication: Marcot, B.G., Woo, I., Thorne, K.M., Freeman, C.M., and Guntenspergen, G.R., 2020. Habitat of the endangered salt marsh harvest mouse (Reithrodontomys raviventris) in San Francisco Bay....

This dataset consists of carbon, nitrogen, and sulfur stable isotope data from primary producers, invertebrates, and fish from the Nisqually River Delta, Washington from 2011, 2012, and 2015. Data were collected to determine food web structure in different habitat zones within the entire river delta. Data collection for primary producers and invertebrates were led by U.S. Geological Survey, while all fish capture studies were led by the Nisqually Indian Tribe. These data support the following publication: Davis, M.J., Woo, I., De La Cruz, S.E.W., Ellings, C.S., Hodgson, S., and Nakai, G., 2024. Allochthonous marsh subsidies enhances food web productivity in an estuary and its surrounding ecosystem mosaic. PLOS...

This dataset provides terrestrial, aquatic, and benthic macroinvertebrate data at four sites within Willapa National Wildlife Refuge.

Methylmercury concentrations and stable isotope ratios were measured from back feathers of California black rails (Laterallus jamaicensis coturniculus) and six taxa of their invertebrate prey (Amphipoda, Arachnida, Coleoptera, Diptera, Gastropoda, and Hemiptera). Samples were collected from three wetlands in the spring and summer of 2005 and 2006.
This research focuses on assessing large scale tidal marsh restoration for the carbon co-benefits of foodweb support and carbon sequestration potential. By assessing wildlife co-benefits with carbon accounting, this project will link traditional objectives of protecting, restoring, and managing diverse wetlands to support habitats and species with carbon dynamics and sequestration. This study addresses interconnected C processes and dynamics including: * Identify carbon sources that support Chinook foodwebs * Compare to the carbon sources that are stored in peat * Determining Net Ecosystem Carbon Balance within in a reference and restored marsh * Evaluate land use and vegetation change over time * Assessing...

The ongoing restoration of more than 200 hectares of estuarine habitat at Willapa National Wildlife Refuge, southwestern Washington, is expected to benefit a variety of species, including salmonids that use estuarine and tidal marshes as rearing and feeding areas as well as migratory waterbirds. During March through June 2014 and 2015, this study was initiated to assess aquatic prey resources. We collected data on environmental variables and invertebrate community structure, and the taskforce provided salmonid diet data at restored (Lewis Stream and Porter Point) and reference (Greenhead Slough and Ellsworth Creek) sites. We analyzed these data to determine the functional capacity of the estuary for supporting invertebrate...
Primary and secondary consumers are important links in the trophic transfer of methylmercury, and their methylmercury concentrations are often measured to assess the potential risk of toxicity to higher trophic level consumers, including humans. A better understanding of the link between methylmercury production in sediments and methylmercury bioaccumulation in tidal marsh primary and secondary consumers will improve the design of contaminant monitoring, remediation, and restoration efforts, thereby protecting human and wildlife health. To advance this goal, we characterized spatial variation in sediment biogeochemistry and methylmercury concentrations of sediments, water, and consumer tissues at a meso-scale among...
This data release includes 9 GeoTIFF rasters that represent percent cover of intertidal microbial biofilm on the mudflats of South San Francisco Bay, CA between June 2020, and June 2022. Rasters follow the naming scheme biofilmPC_YYYYMMDD_10m.tif, where “biofilmPC” describes the dataset, YYYYMMDD is the date of the image, and 10m is the spatial resolution of the raster. Raster data products were derived from 10m Sentinel-2 Muti-Spectral Imager (MSI) imagery, collected and maintained by the European Space Agency (ESA) and published for public access on Copernicus Data Hub (https://scihub.copernicus.eu/dhus/#/home). The area of interest includes the Eden Landing Ecological Reserve and all tidally exposed mudflats...
Macroinvertebrate and environmental data were collected annually in July-August in the year before dike removal (2009) and the first three years after dike removal (2010-2012) at the Nisqually River Delta, Washington, U.S.A. Data were collected along a gradient extending from the inner marsh edge to the delta front and spanning different types of habitat including marsh restored to tidal inundation by dike removal, previously restored marsh, undisturbed reference marsh, and tidal flats. Biological data comprised benthic macroinvertebrate species composition, abundance, and biomass. Environmental correlates included bed elevation; sediment grain size, organic content, and pH; and water column temperature, salinity,...
