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.
