Data frame with three columns: station, latitude and longitude, i.e., with the station coordinates as recorded in the deployment log.

log_crs

The crs of the coordinates in log_coords.

coast_shp

Shapefile of the coast for comparison to the station location. The resolution of the shapefile can impact the results of this test. Coarse resolution may result in false positives for overlapping with land. If NULL, must be connected to the Perennia R drive.

Value

Logical value. Returns TRUE if the log coordinates are in the ocean. Returns FALSE and a Warning if the coordinates overlap with land.
