seal: Data for one foraging trip by a male northern fur seal (NFS).

Description

seal$locs contains xyt locations for argos fixes on the seal's location in the "datetime", "latitude", and "longitude" columns.

seal$cov.df contains a data.frame of spatial covariate values for sea surface temperature (sst), chlorophyll A levels (chA) and net primary production (npp).

seal$sim.obj is a fitted "sim.obj" obtained using the "crawl" package in R.

Usage

data("seal")
