The October Ballena cruise objective was to sidescan the NMFS study area
which encompasses the proposed Calif. State fish reserve off Vandenberg
AFB. Guy Cochrane and Fred Payne (Elec. Tech.) were the USGS crew. The
NOAA crew consisted of Marcus Lebek (Capt.), Adam Petusky, and Sarah
Fangman. The Ballena was mobilized with the Klein 2000 system on Oct. 13.
Data was collected off Pt. Arguello from Oct. 16-18. and Oct. 20-21. Use
of the Vandenberg AFB pier for a night anchorage was not possible because
the sand has filled in the embayment; we anchored off Government Point. We
were able to acquire about 200 trackline km of data which will produce
about 70 square km of coverage, 60% of the data required to map benthic
habitat in the NMFS study area. There was evidence of recent oil seepage
on the sea surface in an area where pock marks were observed on the
seafloor. We were driven out of the area by high swells and had to spend
the remainder of the cruise filling in data gaps in the areas southeast of
Santa Cruz and Santa Rosa Islands, and southwest of Anacapa Island. The
data were collected with 275 m line spacing and 200 m range. The 4KHz
subbottom profiler was used throughout. The R/V Ballena was demobilized
Oct. 29. Our next mapping cruise will be off the R/V MacArthur in May/June
in conjunction with year two Sustainable Seas operations.
