AIS data prepared by Statsat AS for December 2020
<p>AIS data prepared and provided by Statsat AS (Norway) in the framework of the T-SAR project (<em>IKTPLUSS programme on reducing digital vulnerabilities, </em><strong>10 MNOK from the Research Council of Norway, Norway</strong>).</p> <p>The dataset contains AIS data (satellite + other) on a global coverage for 2020. There is one zip file and its name is the month (01 for January to 12 for December) ending with '.zip' and the zip file contains zipped Comma Separated Values (CSV) files; one per day.</p> <p> </p> <p>The CSV zipped files are named with the following convention: ais_YYYYMMDD.zip where YYYY is the year (here 2020), MM the month (01 to 12) and DD the day (01 to 31 depending on the month). For instance, ais_20200101.zip contains one single CSV file called ais_20200101.csv that corresponds to the 1st January 2020.</p> <p>The csv files have one header line:</p> <p>mmsi;lon;lat;date_time_utc;sog;cog;true_heading;nav_status;rot;message_nr;source</p> <p>where:</p> <table> <tbody> <tr> <td> <p><strong>mmii</strong></p> </td> <td> <p>integer</p> </td> <td> <p>MMSI number of the vessel (AIS identifier).

GPS fixes for foraging Southern Giant Petrels (Macronectes giganteus) breeding in Nelson Island, Maritime Antarctic Peninsula (December 2019-January 2020)
<p>In the ZIP file there are two files.</p> <p>One is a .csv with GPS fixes processed using the adehabitatLT to identify events of low speed and high turn movements categorized as foraging. Points within a 250m radius from the breeding colony were excluded, and foraging trips were estimated based on the moment the animals crossed such a radius. Each foraging point was classified as being on land, within 5kms of coastline or on pelagic waters, and on different levels of Sea Ice Cover (from Bremen Sea Ice Remote Sensing data browser https://seaice.uni-bremen.de/databrowser/, Spreen, G., L. Kaleschke, and G.Heygster (2008), Sea ice remote sensing using AMSR-E 89 GHz channels J. Geophys. Res.,vol. 113, C02S03, <a href="http://dx.doi.org/10.1029/2005JC003384">doi:10.1029/2005JC003384</a>).</p> <p>Second file is a R Script with details of the methods for processing the data.</p> <p>Two types of devices were used: Kite-M (Ecotone, NAV individuals) and Axy Trek Marine (Techno SmArt, HP individuals) configurated to collect points each 5 and 10 minutes, respectively.</p> <p>Funded by Fondecyt Iniciación (111 801 75) and Programa Áreas Marinas Protegidas del Instituto Antártico Chileno (24 03 052).</p>
