Hi all, I m not a physicist but a biological oceanographer. I would like to know how should I consider space-time variations of tiny cells in the ocean? Usually people deal with space and time separately but do not compute the data over a space-time scale (which I believe is important especially in regards to the continuous movement of the water in the ocean). Each data point of my data set correspond to a specific location sampled at a specific time, I have data for 6 locations (of a particular region) and 6 time-periods (months), and would like to know the evolution of my tiny cells over a space-time frame. What kind of formula should I apply? How would you approach this problem? Many thanks!!
