Lower left shows an AVHRR image of a Sitka eddy (orange) shedding off of southeastern Alaska. Within the hatched box the dots show part of the track of an adult female northern elephant seal as she transects the eddy while foraging. The top right box shows krigged temperature data from a tag on the seal. The brighter section highlights the subsurface temperature structure of the eddy, as measured by the seal, compared with the surrounding waters
