Figure 14. Yearly grids of CCE sea surface temperature. Bottom right plot is a climatology from all samples pooled. Bottom center panel gives variogram model and search parameter information. The comparison of interpolation methods showed that there is not a single “best” method for interpolating our oceanographic observations to produce what we judge to be reasonably realistic fields of predictor variables. We chose ordinary kriging because this method was least susceptible to bull’s eyes, edge effects, or other artifacts where data are sparse. The kriged yearly fields produced for cetacean-habitat modeling capture both mesoscale and larger scale habitat variability that might influence the distribution of cetaceans. However, it is important to remember that the yearly field is neither a snapshot nor a mean of oceanographic conditions during the three- to four-month survey. It is appropriate to use such a field in developing habitat models using cetacean data collected concurrently with the oceanographic data. When using these models for prediction, however, it might be better to use fields of oceanographic parameters derived from ocean-atmosphere models that assimilate ship, buoy, or even remotelysensed data (e.g., Carton et al. 2000). 47
