Bathymetry

There are a couple of seamounts outside the EEZ (called Schmidt-Ott and Erica) that we should be able to reach, if of interest. Seamounts will have a bunch of stuff living on top of them and could have upwelling of deep nutrients up their sides.

In the map below, the pinkish-red shaded area shows the EEZ (200 nm from the coast) within which we cannot do any sampling.

Expected conditions

The pink points on each plot show the location of the mooring (to the west) and the expected glider pick-up (to the east). The circle around them shows approximately the maximum distance we could travel away from these points during the cruise. The white lines show the EEZ.

Reanalysis model forecasts

The following plots are forecasts for 3^rd February 2023 (biogeochemical variables) or 9^th February 2023 (physical variables), which is as far ahead as is currently available. Things will change over the subsequent days but the major features should not alter significantly.
