Inshore Catch Data for Capelin (Mallotus villosus) in the Gulf of Alaska, 1996-2017 Inshore Catch Data for Capelin (Mallotus villosus) in the Gulf of Alaska, 1996-2017
These data consist of larval ( 60 mm) and age-1+ (> 60 mm) Capelin CPUE (Catch per unit effort) from various catch efforts throughout the Gulf of Alaska (GOA) from 1996 – 2017. The dataset contains the following information: fishing gear type, date, time, catch location (latitude and longitude), tow distance, number of capelin caught, and CPUE for capelin greater than and less than 60...
SUPERSEDED: Data Associated with Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015–2017 SUPERSEDED: Data Associated with Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015–2017
This data release has been SUPERSEDED. No data are provided here. Data from HABs sampling data releases have been appended to U.S. Geological Survey data release: https://doi.org/10.5066/P9MLNP9H. This data set is comprised of two tables with results of algal toxin screening for saxitoxin and domoic acid. We used enzyme-linked immunosorbent assay (ELISA) and high-performance liquid...
Data from Common Murre Die-off Surveys and Necropsies Following the North Pacific Marine Heatwave, 2015-2016 Data from Common Murre Die-off Surveys and Necropsies Following the North Pacific Marine Heatwave, 2015-2016
These data are in two tables relating to a die-off of Common Murres in the north Pacific, 2015-2016. The tables provide: 1) beach survey locations, date, time, distance surveyed (kilometers), and number of Common Murre carcasses observed during surveys conducted along the coastline of Alaska to document the 2015-2016 die-off of Common Murres coincident with the North Pacific marine...
Pacific Sand Lance Energy Density, Length, and Age, Prince William Sound, Alaska, 2012-2016 Pacific Sand Lance Energy Density, Length, and Age, Prince William Sound, Alaska, 2012-2016
This data set documents the age, length, dry mass energy density, and dry mass of age-0 and age-1 Pacific sand lance (Ammodytes personatus) captured in Prince William Sound Alaska each July from 2012 to 2016.
Glacier Runoff in Gulf of Alaska Fjords, 2004-2011 Glacier Runoff in Gulf of Alaska Fjords, 2004-2011
Marine ecosystems respond to a range of habitat variability in coastal zones modified by glacial freshwater outflows, biophysical data were collected in three study regions that included four major glacial fjord systems around the Gulf of Alaska. A suite of geographic, oceanographic, nutrient and biological attributes were sampled at these three study regions during peak ice-melt season...
Marine ecology near Tufted Puffin colonies across the Aleutian Archipelago and Alaska Peninsula, 2012-2014 Marine ecology near Tufted Puffin colonies across the Aleutian Archipelago and Alaska Peninsula, 2012-2014
In the North Pacific Ocean and Bering Sea between August 2012-2014, data were collected on sea surface temperature and salinity data, marine bird and mammal surveys, hydroacoustic backscatter data, marine environment surrounding Tufted Puffin colonies, and body condition and diets of Tufted Puffin chicks.

Appendix 7: Application of joint dynamic species distribution models to at-sea survey data for seabirds in the Bering Strait and Chukchi Sea Appendix 7: Application of joint dynamic species distribution models to at-sea survey data for seabirds in the Bering Strait and Chukchi Sea
Mitigating risk to migratory birds from energy development requires information on the distribution and abundance of seabirds in offshore waters. Seabirds are highly mobile, with species-specific seasonal migrations that result in variable patterns of distribution in space and time. In remote offshore marine areas, obtaining useful and current information on resources is difficult to...

Melanism in a Common Murre Uria aalge in Kachemak Bay, Alaska Melanism in a Common Murre Uria aalge in Kachemak Bay, Alaska
In accord with melanism being uncommon in birds, we could find only six published records of completely melanistic Common Murres Uria aalge, one of the most widely and intensively studied of all seabirds. We added to the record by observing a Common Murre in completely dark, melanistic alternate plumage every summer from 2017 to 2021 at Gull Island in Kachemak Bay, Alaska, USA. In 2017...

Diet analysis using generalized linear models derived from foraging processes using R package mvtweedie Diet analysis using generalized linear models derived from foraging processes using R package mvtweedie
Diet analysis integrates a wide variety of visual, chemical, and biological identification of prey. Samples are often treated as compositional data, where each prey is analyzed as a continuous percentage of the total. However, analyzing compositional data results in analytical challenges, for example, highly parameterized models or prior transformation of data. Here, we present a novel

Another bad year for seabirds on Gull Island Another bad year for seabirds on Gull Island
The USGS monitored Black-legged Kittiwake and Common Murre populations on Gull Island from 1995-1999, and from 2016-2021, following the 2014-2016 northeast Pacific marine heatwave. USGS research, which is supported by the USGS and BOEM, includes population monitoring, and quantifying breeding success and predator disturbances. This information is preliminary or provisional and is subject...

Kittlitz’s murrelet seasonal distribution and post-breeding migration from the Gulf of Alaska to the Arctic Ocean Kittlitz’s murrelet seasonal distribution and post-breeding migration from the Gulf of Alaska to the Arctic Ocean
Kittlitz’s Murrelets (Brachyramphus brevirostris) nest during summer in glaciated or recently deglaciated (post-Wisconsin) landscapes. They forage in adjacent marine waters, especially those influenced by glacial meltwater. Little is known of their movements and distribution outside the breeding season. To identify post-breeding migrations of murrelets, we attached satellite transmitters...

Monitoring the recovery of seabirds and forage fish following a major ecosystem disruption in Lower Cook Inlet Monitoring the recovery of seabirds and forage fish following a major ecosystem disruption in Lower Cook Inlet
Following the North Pacific marine heatwave of 2014-2016 and associated extreme die-off of seabirds in the winter of 2015-2016, we repeated historical marine bird and forage fish surveys around two seabird colonies (Gull Island, Chisik Island) in lower Cook Inlet during 2016-2019 in order to document immediate and lingering impacts of the heatwave on resident fish and seabird populations...
