OBIS-USA brings together marine biological occurrence data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. Waters or with U.S. funding. Coordinated by the Science Analytics and Synthesis (SAS) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biogeographic Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization) International Oceanographic Data and Information...

This part of the Oregon OCS data release presents marine mammal observations from cruise 2014-607-FA in the Floating Wind Farm survey area. The survey was conducted using 12 hour day operations out of Charleston Harbor near Coos Bay, Oregon. The cruise plan consisted of 23 days on site split between sonar mapping and video ground truth surveying. Activities parsed out to nine days of sonar mapping, three days of video surveying, eight days of no operations due to weather, and three days mobilizing and demobilizing (table 1). Typically the Snavely would transit out to the survey area in an hour at a speed of 20 knots. Marine Mammal observations were made during the multibeam sonar mapping portion of the cruise only....

Three albatross species breed at Midway Atoll: black-footed (Phoebastria nigripes), Laysan (P. immutabilis), and short-tailed (P. albatrus). This dataset contains the boundaries of survey area sectors used during the USFWS albatross censuses at Midway Atoll National Wildlife Refuge. The entire area of the atoll is divided into 61 unequal-area sectors. Sector boundaries were established by the USFWS. USGS digitzed the sector boundaries using satellite imagery and data points collected during the 2011-2012 albatross breeding season (hatch year 2012).

Approximately one-third of the global population of black-footed albatrosses (Phoebastria nigripes) nest at Midway Atoll in the Northwestern Hawaiian Islands. As part of an effort to monitor albatross at this globally important site, USFWS personnel and volunteers conduct an annual, spatially-explicit, atoll-wide albatross census during the peak nesting when albatrosses are attending an egg (December-January). During the 2011-2012 breeding season (hatch year 2012) the census was conducted December 16, 2011–January 8, 2012. Albatross nest counts during the census were divided into 61 historically established, spatially-explicit sectors of unequal area. Within a sector, surveyors walked parallel transects approximately...

This dataset provides summary statistics of multiple sage-grouse microhabitat characteristics of the Great Basin. These data support the following publication: Coates, P.S., Brussee, B.E., Ricca, M.A., Dudko, J.E., Prochazka, B.G., Espinosa, S.P., Casazza, M.L., and Delehanty, D.J., 2017, Greater sage-grouse (Centrocercus urophasianus) nesting and brood-rearing microhabitat in Nevada and California—Spatial variation in selection and survival patterns: U.S. Geological Survey Open-File Report 2017-1087, 79 p., https://doi.org/10.3133/ofr20171087.

The St. Clair River delta, part of the St. Clair-Detroit River System (SCDRS), is the most fished coastal wetland area in the Laurentian Great Lakes and provides nursery habitat for a variety of fish species; however, few large-scale surveys of early fish life stages have been performed since the 1980s. Larval fish, zooplankton, and aquatic plants were sampled at 21 sites in delta channels and backwaters of the St. Clair-Detroit River System (SCDRS; USA/CAN) from May to July in 2010 and 2011 to characterize the habitats and resources used by larval fish in the delta. Larval fish were captured using conical nets and light traps, and diets from larval white sucker (Catostomus commersonii) were collected at three sites.
