Summary of Cruise:
The first leg of the cruise was accomplished with Annette Brown as the field party chief, conducting an ichthyoplankton survey between Unimak Pass and the Shumagin Islands from May 21 to May 24. The ship then proceeded to Kodiak to pick up both the Munson for small vessel work and the remaining scientists.

A pre-survey was conducted to set a threshhold for an adaptive survey of the Kodiak to Semidi Island region. The pre-survey took approximately 30 h. A Mocness series was conducted with 8 nets towed obliquely from 100m to the surface in a consecutive series to examine small-scale horizontal patchiness.

The adpative sampling grid was occupied for approximately 81 hours in coordination with sampling by the Wecoma. The grid sampling was delayed by an emergency dropoff of a scientist in Larsen Bay, the onset of a storm with high winds and waves, during which sampling was dangerous, and the rescue of a small fishing vessel floundering in the storm. These activities took about 22 hours.

During the final portion of the cruise, the bongo survey was extended through the upper portion of Shelikof Strait and small vessel (Munson) sampling in waters inaccessible to the Freeman was conducted using the 60cm bongo gear. Three tows were completed using the Munson in Wide Bay and Uyak Bay. In general, the small vessel work was successful as an intitial attempt, and some recommendations for improving the sampling capability of the Munson will be made.

The officers and crew of the Miller Freeman did an extremely good job meeting the demands of the scientific sampling required during this cruise. Particularly during the adaptive sampling and Munson sampling projects the crew needed to be flexible and make some adjustments and decisions in haste, which they accomplished admirably.
