Abstract: |
Interpolated dugong GPS tracks recorded in 2012, 2013 and 2019 over the west coast of New Caledonia, South Pacific. GPS locations were filtered to remove invalid locations of uncertain QFP and unresolved QFP and locations implying unrealistically rapid movements (speed > 10 km/h). When a track was interrupted for more than 10 hours, the track was considered to be constituted by several segments, which were subsequently modeled separately. Track segments were projected in a UTM coordinate system and were interpolated hourly with a Continuous-time Correlated Random Walk (CRW) model using the "crawl" R package (version 2.2.3). Residence time was calculated along the crawl-interpolated tracks to assess movement type (higher values indicating Area Restricted Search when animals slow down and display more sinuous paths). Tidal cycle data were acquired for each hourly dugong position from in situ tide gauge measurements at the Numbo station in Nouméa, New Caledonia (REFMAR, data.shom.fr). Dial cycle was approximated by dividing days into four phases: dawn (3 a.m – 9 a.m), day (9 a.m – 3 p.m), dusk (3 p.m – 9 p.m) and night (9 p.m – 3 a.m). |
