Hypothetical ships on routes through Kattegat
Description
The ship routes and ships used in the study by Nabe-Nielsen et al. (2014). The fix points that define the routes use the UTM zone 32 projection, (EPSG:32632; see https://epsg.io/32632).
The definitions of the ships has been modified since earlier versions of DEPONS (i.e. 2.1 and erlier) in that it now includes ship length, type, and speed (in knots). These are used for calculating the sound source level (following McGilliwray)
Automatic identification system (AIS) data for three ships in Kattegat and the Western Baltic from 20 Dec 2015. The data set includes the variables id (the Maritime Mobile Service Identity number), time, speed (in knots), type, length (in meters), x and y (which provide the coordinates of the ship at a given time. The coordinates use the UTM zone 32 projection (CRS = "+proj=utm +zone=32 +units=m +no_defs +datum=WGS84"). Data were downloaded from the Danish Maritime Authority web page (https://dma.dk).
