MergedFileGDB.gdb is a geodatabase which contains the feature class MergedDynamicEffortPts10kmConstrained.  

For each 10 x 10 km cell the feature class contains the following information:

Gps_Date: date and time of the survey effort (provided by a GPS logger)

Total_Length: total of linear effort in kilometers

Depth: depth in meters

Slope: slope in degrees

Dist_Seamount: distance to nearest seamount in kilometers

Dist_Canyon: distance to nearest canyon in kilometers

VGPM_Monthly: vertically generalized primary productivity in mg C m-� day-1 with a contemporaneous monthly resolution

SST_Monthly: sea surface temperature in degrees Celsius with a contemporaneous monthly resolution

EKE_Monthly: eddy kinetic energy in cm� s-� with a contemporaneous monthly resolution

The feature class is projected to a custom Lambert Azimuthal Equal Area projection.

The covariates folder contains the following rasters of environmental covariates:

Depth_10km_mean_10km.img: depth in meters

Dist_to_canyons_costdist_10km.img: distance to nearest canyon in kilometers

Dist_to_seamounts_costdist_10km.img: distance to nearest seamount in kilometers

Slope_10km_mean_10km.img: slope in degrees

EKE_climXX.img: eddy kinetic energy in cm� s-� with a climatological monthly resolution (XX: month)

sst_climXX.img: sea surface temperature in degrees Celsius with a climatological monthly resolution (XX: month)

vgpm_climXX.img: vertically generalized primary productivity in mg C m-� day-1 with a climatological monthly resolution (XX: month)

All rasters have a 10 � 10 km spatial resolution and are projected to a custom Lambert Azimuthal Equal Area projection.
