Coarse bathymetry for the example data (demonstration only)

Source: R/data-docs.R
sebastes_bathy.Rd

A small depth raster covering the area of the sebastes example data (0-45 degrees E, 61-83 degrees N; Barents and Norwegian Seas). It lets the examples, tests and vignette demonstrate depth extraction in make_prediction_grid() without the ~85 MB bathymetry download that ggOceanMaps::get_depth() needs on first use. It is too coarse for real analyses; use sebastes_depth() only for demonstrations.

Usage

sebastes_bathy

Format

A list with three elements:

lon

Cell-centre longitudes (ascending, decimal degrees).

lat

Cell-centre latitudes (descending, decimal degrees).

depth

Integer matrix (length(lon) x length(lat)) of depth (m, positive down). NA on land.

Details

Derived from ETOPO 2022 (60 arc-second global relief model, NOAA National Centers for Environmental Information; public domain), averaged over 3 x 3 blocks (about 11 km in latitude) and rounded to the nearest 10 m.
