Here we present a time series of San Francisco Bay bathymetric grids created from historical hydrographic surveys collected by the National Ocean Service (NOS) and its predecessor, the United States Coast and Geodetic Survey, from the 1850s to 1980s and one additional survey of south San Francisco Bay collected in 2005 by Sea Surveyor, Inc. Using surface modeling software, the soundings...

Monosaccharide anhydrides (MAs), or anhydrosugars which include levoglucosan, mannosan, and galactosan are combustion products of cellulose and hemicellulose that are used as biomass burning tracers. These fire biomarkers are incorporated into smoke plumes, transported through the atmosphere, and return to the surface through wet and dry deposition that can be archived in ice cores. Here...

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...

Federally-threatened ago-0 spring Chinook salmon (Oncorhynchus tshawytscha) were acoustic tagged and released near Lookout Point Reservoir to estimate passage and survival during an experimental reservoir drawdown operation that was designed to facilitate downstream passage through two reservoirs and dams. The experimental operation consisted of lowering the water surface elevation of...

Data were collected at the Flag Springs Complex on the Wayne E. Kirch Wildlife Management Area in Nevada to study the seasonal movements, habitat use, and survival of White River Spinedace. The dataset comprises information on PIT tagged White River Spinedace detected passively by remote antennas, along with habitat characteristics data. Length, weight, and species data were recorded...

Spring viremia of carp virus (SVCV) is a rhabdovirus that primarily infects cyprinid finfishes and causes a disease notifiable to the World Organization for Animal Health. Amphibians, which are sympatric with cyprinids in freshwater ecosystems, are considered non-permissive hosts of rhabdoviruses. The potential host range expansion of SVCV in an atypical host species was evaluated by...

6PPD-Quinone (6PPDQ) was recently implicated in mass pre-spawn mortality events in adult coho salmon (Oncorhynchus kisutch) in the Pacific Northwest. Since then, studies have reported highly variable toxicity among fish species, including within the salmonids. This dataset explores the sensitivity of coastal cutthroat trout (Oncorhynchus clarkii clarkii) at three life stages: alevin, 5...

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...

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.

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...

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...
