Level 1 Level 0 + time-referenced, georeferenced

Level 2 Level 1 + derived geophysical variables

Level 3Level 2 + gridded to uniform space-time grid scales

Level 4 Level 3 + model output or results from analyses

Extension ActivitiesAccess ocean topography image, same data –

compareUse same technique to predict different fish

caught from different portDevise a plan to “ground-truth” the satellite-

based SSTFind & process a MODIS image for SST Devise a plan for determining in which

season coastal eddy currents and upwelling are most common

Explore linear relationship between SST and pixel brightness value in Level 3 data
