Dear Marmam subscribers, I've asked around for information on sei whale dive depths and durations, but have only been able to turn up some basic information on respiration rates published in Schilling et al 1992's paper in Fishery Bulletin and in the Gambell chapter in the Handbook of Marine Mammals (that notes durations of up to 15 mins, but with no supporting source for that information). I've contacted various folks at NMFS and other locations, but haven't been able to turn up much. I know that there has been some recent sei whale tagging work off the Azores, though I haven't seen any dive information published yet. If someone out there has information that could help me, I would very much appreciate it if you would contact me directly.
