This database is a compilation of marine mammal and seabird information collected along the Pacific coast of the United States and U.S. territories in the Pacific from surveys that were solicited among regional research communities and persons. Information from standardized surveys was gathered from 2015 to 2018 and includes programs and researchers who collected information regarding seabirds since 1960.

This data package contains one table with morphometric and diet information for "non-die-off" seabirds captured and collected in southcentral and southwest Alaska. Data pertains to birds captured (live) or collected (lethally) including, bird identification numbers, sampling dates, geographic locations, body measurements, diets (from either stomach contents or regurgitated prey), and sex and age of the bird when discernible. Common Murres (Uria aalge) and Black-legged Kittiwakes (Rissa tridactyla) were captured from their breeding colonies in lower Cook Inlet, Alaska, 2016-2023. Kittiwakes, murres, Glaucous-winged Gulls (Larus glaucescens) and Horned Puffins (Fratercula corniculata) were collected in Prince William Sound, Cook Inlet, and Unalaska.

This data release includes 2 child items with tracking data for Northern Fulmars, a seabird species that breeds throughout northern ocean regions and spends the winter at-sea in the northern hemisphere. Child Item 1: "Argos Satellite Tracking Data for Northern Fulmars (Fulmarus glacialis) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Northern Fulmars (Fulmarus glacialis) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

Several bureaus within the Department of Interior compiled available information from seabird observation datasets from the Atlantic Outer Continental Shelf into a single database, with the goal of conducting research and informing coastal and offshore planning activities. The cooperators were the Bureau of Ocean Energy Management's (BOEM) Environmental Studies Program (www.boem.gov/Environmental-Stewardship/Environmental-Studies/Environmental-Studies.aspx), the U.S. Fish and Wildlife Service's (USFWS) Division of Migratory Bird Management (www.fws.gov/migratorybirds/) and the U.S. Geological Survey's (USGS) Patuxent Wildlife Research Center (www.pwrc.usgs.gov). The resulting product is the Atlantic Offshore Seabird Dataset Catalog, which characterizes the survey effort and bird observations that have been collected across space and time. As of December 2013, the database contains over 70 datasets from 1906-2013 with about 300,000 records of seabird observations. The data is comprised of roughly 50 datasets from 1938-2013 with about 260,000 observation records. This archive is a subset of the main database, excluding datasets from surveys where the scientific design was not specifically designed to sample marine birds (e.g., coastal portions of National Audubon Society's Christmas Bird Counts). The full archive of scientific data contains information on individual observations as well as survey effort. Each observation record has a unique point location, date and time, species and observation count. There may also be biological information related to the sighting, such as animal age or behavior. The survey effort information (i.e., weather variables) may have been recorded for each individual observation but was more often recorded at the transect (line along which the plane or boat traveled) level. The dataset contains data primarily for seabirds, but some other observations accompanied bird data submissions and were not discarded: marine mammals, turtles, fish, and non-biological sightings such as other boats, fishing gear and trash. The data is in CSV format, with an associated file detailing the data structure in CSV format. A detailed metadata record in Federal Geographic Data Committee (FGDC) format and a final report in .pdf format is included with these data. Data use must take into account use constraints (data limitations) listed within the included metadata record, and cite the Atlantic Offshore Seabird Dataset Catalog, USGS, 2013.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted puffins (TUPU) located on Middleton Island in Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sample ("seabirdDiets_foodSample_middletonIsland.csv"). The second table is similar to the first table, however, the samples have been subdivided by individual prey species ("seabirdDiets_samplePrey_middletonIsland.csv"). The third table consists of information specific to sampled prey items, such as prey taxa identification and morphometrics ("seabirdDiets_preyItems_middletonIsland.csv"). The fourth table consists of processed diet information and indices specific to Black-legged Kittiwake and Rhinoceros Auklet prey ("seabirdDiets_RHAU_BLKI_diets_middletonIsland.csv"). The fifth table contains prey species and seabird species taxonomy information ("seabirdDiets_speciesTaxonomy_middletonIsland.csv"). All samples included in the tables of this data release were collected during the spring and summer months from 1978-2022.

This dataset describes marine bird and mammal surveys conducted in August 2012-2014 in the North Pacific Ocean and Bering Sea. Data were collected to document the at-sea distribution and abundance of marine birds and mammals, and were conducted using standard strip width transect protocols (Gould and Forsell 1989). One observer and one recorder identified and counted birds on transect at all times. Surveys were recorded using a DLOG system and exported into a .csv file. This dataset contains survey data consisting of: date, time, latitude, longitude, record number, data type, species, count, behavior, distance, observers, observer conditions, trip ID, beaufort, transect type, transect width (m), and comments.
