Access to Data

Below are plots of vorticity, divergence, and shear for the four regions centered on the ship (50 x 50 km, 100 x 100 km, 150 x 150 km, 200 x 200 km). Also, a plot of the actual AREA used in each calculation is given below. For example, the area for the calculation of deformation in each 100 x 100 km region should (ideally) be 10,000 sq km, but if the ship happened to be near the edge of an image then a corner of the 100 x 100 km box could be cut off, and the actual area used in the calculation would be less than 10,000 sq km.
