Bull trout (Salvelinus confluentus), listed as threatened under the Endangered Species Act, are among the more thermally sensitive of coldwater species in North America. The Boise River upstream of Arrowrock Dam in southwestern Idaho (including Arrowrock Reservoir) provides habitat for one of the southernmost populations of bull trout. The presence of the species in Arrowrock Reservoir poses implications for dam and reservoir operations. From 2011 to 2014, the Bureau of Reclamation and the U.S. Geological Survey collected fish telemetry data to improve understanding of bull trout distribution and movement in Arrowrock Reservoir and in the upper Boise River tributaries. The U.S. Geological Survey compiled the telemetry...
This dataset contains tracking durations for several species of sea turtles tagged with satellite tags between 2008 and 2019. It contains information on species, turtle size, capture methods, tag type, how many days each tag transmitted, whether or not the tag was still attached upon recapture, fouling 'status' of the tag, and foraging region. This dataset thus allows estimation of tracking durations for four species of marine turtles tagged in different study sites in the Gulf of Mexico and Caribbean.
Funding for this study was provided by the Bureau of Ocean Energy Management and U.S. Geological Survey (Interagency Agreement no. M12PG00014). This study focuses on obtaining information about populations of Brown Pelican (Pelecanus occidentalis carolinensis) across the northern Gulf of Mexico. Study objectives are to (1) document dispersal, seasonal and annual movements, seasonal home range, and site fidelity of marked adult Brown Pelicans among nesting colonies from the Gulf coast, (2) compare contaminant exposure risk, contaminant levels, and health parameters in adult and nestling Brown Pelicans from various colony sites, and (3) document the relationship of local environmental, nest site characteristics and...

This dataset comprises GPS locations analyzed in Wilkinson et al. (2019): 14,478 deployed GPS locations, for 32 Eastern brown pelicans tracked during Hurricanes Irma, Florence, and Michael in autumn 2017 and 2018, respectively. Funding for this study was provided by the U.S. Geological Survey Ecosystem Missions Area, and facilitated by Mona Khalil (USGS). Among seabirds, the Eastern brown pelican (Pelecanus occidentalis carolinensis) is a large-bodied coastal species inhabiting nearshore habitats. Breeding on sea islands free of mammalian predators in subtropical and tropical North America, colonies range in size from 10 - 5000 pairs. Egg laying (clutch size of 2-3 typical) occurs primarily in April and May, with...

This dataset contains all input parameters required to perform integrated step selection analysis (iSSA) to quantify marine turtle habitat selection relative to marine protected areas throughout coastal Florida and the Gulf of Mexico. The iSSA is a flexible approach to compare the environmental attributes of observed steps (the linear segment connecting two consecutive observed positions of an animal) against a group of alternative steps taken from the same starting location. Information contained in the dataset includes original PIT (passively induced transponder, a unique identifier for each turtle), step ID, step length and log of the step length, turning angle and cosine of turning angle, start and end date...

This dataset contains cumulative threat data for several species of male sea turtles tagged with satellite tags between 2009 and 2020. It contains information on species, capture date, days during tracking spent in marine protected areas, shipping lanes, near the coast, near oil rigs, and within known fishing operations. This dataset thus allows estimation of threat levels from these anthropogenic pressures for sea turtles tagged in different study sites in the Gulf of Mexico and Caribbean.
