04jan/bioacoustics -
There were several types of bioacoustic transects conducted with a towed 120 kHz
transducer (BioSonics) during the annual January cruise.
A. at ship speed 2.0 to 2.5 kts
1) Discrete acoustic transects were done at each station simultaneously with the
2-M and 1-M net tows, for the 200.*, 300.*, 400.*, 500.* and 600.* cardinal
lines, and the inshore stations.
2) Palmer nearshore transect A-E and F-J during the cruise.
B. At ship speed 4.0 to 4.5 kts
Continuous acoustic transects simultaneously with seabird observations over high
density grid 1 as established in Jan 1995.

04jan/brcensus - At-sea seabird censuses to determine abundance and distribution
in the Palmer LTER marine grid between the 600 and
200 lines during the 03-04 season. The files provide general
spatial and environmental data associated with both stationary
and moving transects, and specific data on the species encountered
(including marine mammals), their abundance, distribution and
behavior.

04jan/krillspawn - Spawning frequency and egg production experiments were conducted on
board the Laurence M. Gould (04-01) in a flow-through aquarium at ambient temperature
according to the method of Ross and Quetin (1983). These experiments yield estimates of
spawning intensity, i.e. the percent of the females in the reproductive cycle spawning per day, and
the interbrood period or interval between multiple batches of eggs. Measurements of embryo size
and the batch volume are indices of individual reproductive output during the cruise.
