Objectives of Cruise:
1. To recover and deploy subsurface and surface oceanographic instrumentation moorings in support of
2. To complete CTD casts for mooring instrument calibrations and to further identify ocean structure and water movements in this area.
Summary of Operations:
(Statistical data: Number of specific operations and samples collected from COD.)
Operations:
CTD casts 85
Mooring deployment 26 (2 surface, 24 sub-surface)
Mooring recoveries 15 (1 surface, 14 sub-surface)

Samples Collected:
CTD salinity comparison samples 82

Summary of Cruise:
The primary objective of this cruise was to recover and deploy an extensive array of oceanographic moorings. Mooring related activities were usually accomplished during hours of daylight (0700-2300). CTD casts were completed in conjunction with mooring recoveries and deployments, CTD lines were completed primarily during the night. Within this report are tables listing the times and dates each mooring was recovered or deployed and a table listing the position, time and date of each CTD cast. There is also a chart of each mooring location and one showing each CTD cast location.

We
deployed the FATE subsurface ADCP profile mooring and with some difficulty
recovered the FATE surface mooring. It
appears the surface FATE mooring was deployed with a longer then expected
mooring line causing the acoustic release to lay horizontal on the ocean
bottom. The acoustic release would not
operate correctly until we recovered enough of the surface mooring (anchor
attached) to pull the release into a vertical orientation. At that point the release responded properly,
dropped the 5000 lb anchor and we were able to recover the remainder of the
mooring. The 2002 FATE surface mooring
was then deployed without incident. A

We moved north toward Seward to the first of 13 moorings on the GLOBEC line. With the exception of GBM3, a surface mooring, the recoveries and deployments along this line were routine and successful. Please refer to the mooring table and chart of mooring locations for the dates and times these moorings were completed.
Arriving
at GBM3 we could not visually locate the 9 foot diameter mooring surface float
and due to the earlier failure of the
On
22 May we broke operations to complete a touch and go inport
in Seward
Following the personnel transfer at Seward we steamed back to the GBM3 location. A new GBM3 surface mooring was deployed along with a subsurface mooring that included the acoustic plankton counter and an iron sampler.
Completing the planned operations on the GLOBEC line we steamed west to a line of 3 subsurface moorings south of Gore Point. The recovery and deployment of GP32, 34 and 36 was routine and without incident.
Following
our operations on the Gore Point line we steamed west to the inshore
The work at CB1 marked the end of Cruise EW-02-05 and the completion of our objectives. We arrived at the Kodiak Coast Guard Base the afternoon of May 24th, approximately 14 hours ahead of our original schedule.

This
cruise marked the first time PMEL/OERD-2 attempted extensive mooring operations
aboard R/V Maurice Ewing. As can be
expected, with any new platform there was some settling in time at the start of
the cruise. Through the tireless efforts
of the Captain, mates and deck department we were able to make the adjustments
to the vessels equipment and back deck layout necessary to meet our cruise
objectives. For future considerations,
the
As expected, all members of the scientific party and the representatives from PMEL engineering branch willingly put in the long hours and the extra effort necessary to make this cruise a success. The working relationships that developed between the vessel crew and scientific party was very productive and very positive.
Note:
To keep the mooring and CTD locations discernable the scale was reduced on the
following two charts. The subsurface
