This data set contains water and air temperature data in addition to duration of time spent at temperature to provide estimates of daily activity and consequent demand for food...

The integrated modeling framework for Antarctic krill (Euphausia superba) has been extended to include estimates of krill growth consistent with survey data and to use...

An integrated, age-structured model was fitted to different combinations of survey data using two forms of selectivity (logistic or double-logistic) with time-constant or...

Data were collected from two penguin monitoring sites in the Antarctic peninsula region between 1977 and 2015 using traditional census methods. Seabirds observed in this study...

Dataset contains continuous underway measurements of ship’s position, sea surface temperature, salinity, turbidity, fluorescence, air temperature, barometric pressure, relative...

A Cape-wide census of Antarctic fur seal (Arctocephalus gazella) pups (live and dead) occurs every year once pupping is over. The census occurs in the last days of December, on...

Estimates of daily activity and consequent demand for food during winter are scarce for many polar seabirds, yet essential for assessing constraints on foraging effort, demand...

Data were collected from several penguin monitoring sites in the Antarctic peninsula region, the South Orkney Islands, and East Antarctica between 1977 and 2017 using...

At-sea distribution and density of marine mammals and seabirds. Seabird and marine mammal observations were collected from research vessels during transits between stations, to...

We aerially surveyed leopard seals of known body size and mass to test the precision and accuracy of photogrammetry from a small UAS. Flights were conducted in January and...

Zooplankton research in the US AMLR Program focuses on the link between prey production, availability, and climate variability in relation to predator and fishery demands....

Calibrated, integrated, and averaged acoustics data, including estimates of krill (Euphausia superba) biomass density, collected around Elephant Island, the South Shetland...
