****************************************************************************************

The publiction depended on versions of a dataset, all three available here.

(1) xdat.Full:
The full dataset, with highest available resolution. 
For Models 1,2,3,4,7,9.


(2) xdat.21_23:
A subset of the full dataset for Years 2021-2023, where USV sampled environmental variables are included . 
For Models 5 and 6 (ref. Carlsen et al., in rev.).


(3) xdat.Agg:
Aggregated data (2x2 km2).
For Model 8 and "aggregated" spatial prediction.

All variables are explined in Table 1 (below, but see Carlsen et al., for higher readability).

//Necessary explanation of variable abbrevations://
CMSI variables:
SO_surf = CMSI provided Salinity 
Mean_thetao_SST = CMSI provided Temperature
Chl_surf = CMSI provided surface Chlorophyll
Mean_NS_vo_Wclm = CMSI provided North-South currents
Mean_EW_uo_Wclm = CMSI provided East-West currents
Mean_current_speed = CMSI provided Current speed
Depth = CMSI provided topographic depth (i.e. depth of seabed)

X,Y = coordinates 

USV variables (only in xdat.21_23):
SB_CTCond = USV measured surface Salinity
SB_CTTemp = USV measured surface Temperature
SB_ECO3_CHL = USV measured surface Chlorophyll
