Northern elephant seal tracking and diving – processed data

Northern elephant seals (Mirounga angustirostris) have been integral to the development and progress of biologging technology and movement data analysis. Adult female elephant seals at Año Nuevo State Park and other colonies along the west coast of North America were tracked annually from 2004 to 2020 for a total of 653 instrument deployments and 561 recoveries. These high-resolution diving and location data have been compiled, curated, and processed. This repository has netCDF files containing the raw tracking and diving data. The raw data are available in a second repository (https://doi.org/10.7291/D10D61)., These data were collected from biotelemetry devices attached to adult female northern elephant seals (Mirounga angustirostris) from 2004 to 2020. The instruments collected locations (Argos and/or GPS) and continuously recorded depth throughout the animals' trips. Data were processed in MATLAB and R using custom code, the IKNOS package for dive data processing, and the aniMotum package for track processing. The details of data collection and processing are documented in the data descriptor paper associated with this dataset. In addition, all code used to process the data are available on GitHub and Zenodo.

Northern elephant seals (*Mirounga angustirostris*) have been integral to the development and progress of biologging technology and movement data analysis, which in turn continue to improve our understanding of this and other species. Adult female elephant seals at Ao Nuevo Reserve and other colonies along the west coast of North America were tracked annually from 2004 to 2020 for a total of 653 instrument deployments and 561 recoveries. Here, we describe the compilation and curation of these high-resolution diving and location data, which are now publicly available through two Dryad repositories. All the processing code and workflow are also publicly available through GitHub and Zenodo. This data set represents 3,942,130 dives and 610,372 locations collected from 475 individual seals with 178 repeat samplings over 17 years.
