Hi,
Thank you for your response. Generally, yes. The data is of whale sightings, and there are areas where the whales are seen most often (and where the highest survey effort is), so there are generally a couple pockets where the values are high, surrounded by a lot of 0's. The values are of numbers of whales accounting for the level of survey effort. So there are ares where there is at least some effort, but no whales sighted. These are most likely false 0's, meaning that those aren't necessarily areas where there are 0 whales there, but at the time of the survey, no whales were seen there. I'm also working on other models that might deal with this issue, however, my overall goal is to created an interpolated surface of whale distribution, which is why I'm trying to figure out how to make my data appropriate to use a krigging method.
Thanks for your help on this,
Brooke
