During the night we crossed the cyclonic
feature from the southeast to the northwest. No whales were heard during
our survey across the interior of the cyclone. At the northwestern side
of the cyclone, the currents were directed roughly southwestward at less
than 1 knot. Two whales were heard about 10:30 UTC and tracked for about
3 hours, but no additional animals were found. The 3-D passive acoustic
tracking array was re-deployed by 13:50 UTC. The ship then was
maneuvered past whales for 3-D depth tracking tests. During this time
additional whales were acquired by the visual team, and at about 15:00
UTC (27o11.8'N 95o41.6'W), we observed breaching.
At 15:35 UTC, we were with 7 animals, including a mother and a calf.
Rolling seas kept us from launching the small boats, so we continued to
collect 3-D tracking data throughout the day. The 38 kHz fishery echo
sounder was deployed at 19:05 UTC, and the 38 kHz ADCP was turned off.
We were with whales the entire day and into the evening, but seas were
never calm enough to allow small boat operations.Because seas are
expected to continue to prevent small boat operations tomorrow, we
decided to go to Harbor Island tomorrow to pick up materials and
additional spare parts for repairs on RHIB-1. Both hydrophone arrays and
the 38 kHz fishery echo sounder were pulled on board between 01:30 and
02:35 UTC on 13 June 2005. The 38 kHz ADCP was turned on. The third CTD
cast of the cruise was taken at 02:42 UTC on 13 June 2005 and was
located at 27 00.5924'N 95 37.5768'W. The ship was turned toward Harbor
Island immediately after the cast was completed. Our position at 03:35
UTC on 13 June 2005 is 27 01.780'N 95 38.736'W.
