2007-08 V3 CEAMARC-CASO Bathymetry Plots Over Time During Events
The bathymetry data has been checked for accuracy. A routine was developed in R ('bathy_plots.R') to plot bathymetry data over time during individual CEAMARC events. This is so we can analyse benthic data in relation to habitat, ie. did we trawl over a slope or was the sea floor relatively...
