Hello All,

My data are counts of seabirds and marine mammals at a spatial scale of 20 Km i.e I had recorded the position of the ship at the beginning of every 20 Km transect. Now I want to split each 20km transect in to 3km segments to check for spatial autocorrelation among the observations and relate it to the oceanographic features. I had tried with packages sp and rgdal but was not arrive at the r code. Could anyone suggest me how to proceed with this problem?

My data looks like this:
