Version 3 - 2015-10-01 (unreleased)

At request of L. Garrison and K. Mullin, changed modeling period from 1992-2009 to 1994-2009, so that two sightings of "Bryde's or sei whale" in the western Gulf are not included, under the assumption that Bryde's whales no longer occupy the western Gulf. Added bivariate smooth of XY to the model, to concentrate density where sightings were reported.

Version 2.2 - 2015-05-14 (unreleased)

Updated calculation of CVs. Switched density rasters to logarithmic breaks. No changes to the model.

Version 2.1 - 2015-02-02 (unreleased)

Updated the documentation, which is still not complete. No changes to the model.

Version 2 - 2015-01-07 (unreleased)

Added four ambiguous "Balaenoptera spp." sightings to the model, following Maze-Foley and Mullin (2006).

Version 1 - 2015-01-07 (unreleased)

Initial version.
