Field update from our Nov/Dec 2006 Hawai'i project

Collection of survey and sighting data for examination of habitat use
Collecting dead cephalopods for trophic ecology studies
To date (November 25, 2006) we've made progress with all of these goals. We've collected fecal samples from a dwarf sperm whale, short-finned pilot whale and pantropical spotted dolphin. We have deployed two (and recovered one) time-depth recorders on Blainville's beaked whales (the recovered tag stayed on 18 hours and 38 minutes, deployed on a sub-adult male). We've also deployed two "medium-term" satellite tags on Blainville's beaked whales and one satellite tag and a VHF tag on short-finned pilot whales, and all four tags are still working 3-5 days after deployment, despite regular deep (>700 m) dives by both species. We've collected genetic/stable isotope samples from Blainville's beaked whales (sloughed skin collected after tagging attempts), false killer whales (a biopsy), pygmy killer whales (two biopsies), rough-toothed dolphins, and bottlenose dolphins (three biopsies), and have obtained photo-IDs from four groups of Cuvier's beaked whales, three groups of Blainville's beaked whales, one group of very cooperative dwarf sperm whales, two groups of false killer whales, several groups of short-finned pilot whales, one group of pygmy killer whales, rough-toothed dolphins, and two groups of bottlenose dolphins. We've also collected one large squid, found dead floating at the surface, and parts of one small squid, recovered from behind foraging pilot whales. So far, so good.
