For the spatial component, I want to look at where the strandings are occurring more frequently along the coast. Thinking ahead as far as the statistical analysis, what design would you use to divide the coastline up into pieces/parts. Possibilities include line segments, island by island, and geography of the land (sounds and harbors). There is a commercial fisheries component here and I do not want to have any bias in the spatial analysis. My first thought is to create line segments of random lengths or should the lengths be equal in length? Also, shouldn't each segment be independent of the next? Any thoughts would be helpful. Thank you for your time and I will sum.
