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.

Sea Otter Aerial Survey Data from the Outer Kenai Peninsula, Alaska, 2019 Sea Otter Aerial Survey Data from the Outer Kenai Peninsula, Alaska, 2019
This dataset consists of three tables related to abundance and distribution of northern sea otters (Enhydra lutris kenyoni) near the outer Kenai Peninsula, Alaska, based on data collected during a series of population-wide aerial surveys in June 2019. The dataset consists of: (1) sea otter counts along strip transects, (2) sea otter counts in Intensive Search Unit (ISU) within the...
Sea Otter Aerial Survey Data from Western Prince William Sound, Alaska, 2017 Sea Otter Aerial Survey Data from Western Prince William Sound, Alaska, 2017
This dataset consists of three tables related to abundance and distribution of northern sea otters (Enhydra lutris kenyoni) in western Prince William Sound, Alaska, based on data collected during a series of population-wide aerial surveys in June 2017.

Seasonal Resource Selection by Pronghorn near Wind Energy Facilities in Wyoming, 2010-2012 and 2018-2020 Seasonal Resource Selection by Pronghorn near Wind Energy Facilities in Wyoming, 2010-2012 and 2018-2020
Wind energy represents an important alternative to oil and gas extraction to meet increasing energy demands, but it has the potential to disrupt wildlife populations. Because behavioral adjustments, such as altered habitat selection, are a primary way that long-lived species respond to novel disturbances, USGS scientists evaluated effects of wind energy development on pronghorn...
Continuous water-quality data for selected streams in Rocky Mountain National Park, Colorado, water years 2011-19 Continuous water-quality data for selected streams in Rocky Mountain National Park, Colorado, water years 2011-19
This data release contains water-quality and discharge data collected in Rocky Mountain National Park (RMNP), Colorado by the U.S. Geological Survey (USGS) from 10/1/2010 through 9/30/2019 using in-situ sensors and field meters. Data were collected for the purpose of quantifying exchange fluxes of dissolved carbon dioxide (CO₂) from streams. Parameters include daily mean dissolved CO₂...
Daily 30-m fractional snow covered area and summary stats for the National Elk Refuge, Wyoming from 2015 to 2020 Daily 30-m fractional snow covered area and summary stats for the National Elk Refuge, Wyoming from 2015 to 2020
This dataset contains daily fractional snow covered area (fSCA) at 30-m spatial resolution from August 1, 2015 - May 15, 2020 (five winters) for the National Elk Refuge in Wyoming, USA. The following summary statistics are also included: date of snow accumulation, date of snow melt, number of days in year with snow on ground, and percentage of "winter days" in year with snow on ground...
Accelerometer scour monitor data on the Sauk River, Washington, Water Year 2018 Accelerometer scour monitor data on the Sauk River, Washington, Water Year 2018
Accelerometer scour monitors were deployed on the Sauk River, Washington during Water Year 2018 as part of a study on the timing of streambed scour in salmon-spawning habitat. This data release contains data of the three-dimensional orientation recorded at 15-minute intervals for the accelerometer monitors. Each accelerometer scour monitor was comprised of one to two individual...
