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.

Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha) detections in Lookout Point Reservoir and downstream in the Middle Fork Willamette River, Oregon, 2023_24 Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha) detections in Lookout Point Reservoir and downstream in the Middle Fork Willamette River, Oregon, 2023_24
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 on the capture, tagging, and detection of White River Spinedace in the Flag Springs Complex, Nevada 2020-2022 Data on the capture, tagging, and detection of White River Spinedace in the Flag Springs Complex, Nevada 2020-2022
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) Infection Trials of Pacific Northwest Amphibians. Spring Viremia of Carp Virus (SVCV) Infection Trials of Pacific Northwest Amphibians.
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...
Evaluation of Lethal and Sublethal Effects of 6PPDQ on Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) (ver. 2.0, March 2025) Evaluation of Lethal and Sublethal Effects of 6PPDQ on Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) (ver. 2.0, March 2025)
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...
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.
