How Have Group A and Group B Traveled in 2013?

In the beginning of 2013 Group A and B were split.  The J16s were seem with Group B on every encounter in January, making them Group B+ for the sightings in January, 2013.

As the year moved on Group A and Group B traveled together the majority of the season.  In fact there seemed to be more mixing of the Groups when observing J pod, especially during the last part of the season.
Group A and Group B whales may have ended their split...time will tell. 

There were other unusual splits throughout 2013, that included some K pod whales as well, but nothing that would lend itself to attaching a 'shortcut' name to them.
