Description:

Abstract:

This data release comprises 3 datasets used to develop forecasts of autumn body condition for adult female Pacific walruses in the Chukchi Sea during mid and late century time periods. The activity dataset contains daily telemetry records for 218 adult female walruses tracked for periods of 7 to 104 days during 2008-2014, in the Chukchi Sea. Records include the number of hours the walrus was in the water, number of hours the walrus was foraging, study area region where the walrus was located, depths of the foraging locations, and the proportion of the region covered by sea ice. The movement dataset contains telemetry records for 94 of these walruses, giving the dates they moved from one region to another, and the date of the beginning of minimum ice period for that year. The projected-ice dataset contains daily projections of ice conditions in the study area regions derived from 7 general circulation models of future ice availability for mid-century (2045-2054) and late-century (2090-2099) time periods. The movement and activity datasets were developed to model walrus activity and movement as functions of sea ice conditions. The projected-ice dataset was developed to provide input for those models to forecast future walrus activity and movement. Forecasting autumn body condition requires linkage to bioenergetics models.

Purpose:

Develop models of walrus activity and movement as functions of sea ice conditions, forecast future walrus activity and movement as functions of projected future sea ice conditions, and link to bioenergetics models to forecast autumn body condition for adult female Pacific walruses in the Chukchi Sea during mid and late century time periods.

Process_Step:

Process_Description:

We collected Argos satellite telemetry locations from a sample of 216 female walruses between 2 June 2008 and 20 October 2014.

Process_Date: Unknown

Process_Step:

Process_Description:

We filtered Argos locations with an algorithm based on spatial redundancy, movement rates, and turning angles (Douglas et al. 2012).

Process_Date: 2016

Process_Step:

Process_Description:

For analysis, we selected one Argos location for each walrus tracking day so we could associate daily behavioral intervals with environmental covariates. We selected one walrus location each day by retaining the location record(s) closest in time to local noon. If more than one location were equally close to local noon, we selected the location with the highest Argos location quality (LQ), and if they had the same LQ, we selected the location obtained before local noon. If locations of equal LQ were acquired at the same time before local noon, then we averaged the locations.

Process_Date: 2016

Process_Step:

Process_Description:

We derived chronologies of hourly haulout and foraging states of tagged walruses from data collected by a conductivity sensor and pressure transducer on the radio-tag (Fischbach and Jay 2016). Every one or two seconds (depending on the tag model and deployment year), the conductivity sensor indicated whether the tag was in or out of salt water and the pressure transducer indicated the depth of the tag. If >= 90% of the conductivity measurements within a 1-h interval indicated the tag was out of water, the walrus was considered to be hauled out during that interval. If the majority (>50%) of the pressure measurements within a 1-h interval indicated the tag was > 10 m deep, the walrus was considered to be foraging during that interval.

Process_Date: 2016

Process_Step:

Process_Description:

We excluded behavioral intervals obtained within the first 24 hours after tag deployment to guard against the possibility that the tagging process altered behavior during this period. We only included data from walruses that provided = > 240 hours of continuous hourly records that were not missing two or more consecutive daily locations.
