Could you put your data together in a reproducible way? It looks like
this might just be the raw contents of a text file?

If you have it in R use dput() to create the code that will regenerate
your object.

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?
