Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RV Atlantic Explorer (33H4) cruise AE1404
Short name AE1404
Objectives and Narrative Objectives

1. Recover 5 deep-sea moorings off the eastern Bahamas along latitude 26.5N and deploy 4 new moorings along the same line.
2. Recover and redeploy one pressure-inverted echo sounder (PIES) and recover data from 6 previously deployed PIES by underwater acoustic telemetry.
3. Conduct CTD and Lowered ADCP sections across the Florida Current at 27N, Northwest Providence Channel, and along the 26.5N RAPID-MOCHA western boundary line east of Abaco, Bahamas.
4. Perform several additional deep water CTD casts to calibrate moored instrumentation
5. Deploy 10 satellite tracked surface drifters at pre-selected locations.

Narrative

After transiting through Northwest Providence Channel, a "cal-dip" CTD station was done in 4300 m depth east of Abaco to obtain in-situ calibration data for all the moored Seabird microcat instruments. The CTD obtained good temperature and salinity data on the cast but there was a problem with the dissolved oxygen channels and the altimeter data due to a system configuration error. This was fixed and another short test cast was done, which showed all sensors working well. The LADCP system in use on the cruise consists of a downward looking 150 kHz ADCP and upward looking 300 kHz ADCP, both U. Miami instruments. It was discovered during the Abaco section that the U. Miami 150 kHz ADCP developed a problem with one of its beams and gave poor results in deep water casts. It was replaced with an identical 150 kHz ADCP from NOAA, which performed well for the remainder of the cruise.
The Abaco CTD/LADCP section was completed from March 16-22. An incident occurred during CTD004 when the package got temporarily snagged on a nearby mooring. The package sustained only minor damage and was redeployed after a short delay. After CTD008 the ship had to transit to Marsh Harbor and send in a small boat to let off the Chief Engineer due to illness and pick up a replacement, causing about a 17 hour delay. Near the end of the Abaco section, the deeper stations had to be terminated before reaching bottom due to an insufficient amount of conducting cable on the winch. Mooring work commenced on March 22nd with the recovery of bottom lander WBL5 at the eastern end of the Abaco line. All planned mooring operations were successfully completed between March 22-29. Underwater communications were initially difficult, with replies from the releases being either being very faint or not detected, though they could generally be heard on the ship's Knudsen echo-sounder. After swapping out the deck unit and transducers with backup units brought by AOML, it became apparent that the Benthos model UDB-9000 deck units, when paired with their cabled transducers, were not working well with the EdgeTech acoustic releases used on the U. Miami moorings. An older EG&G deck unit with cabled transducer was then used for mooring recovery and deployment, which showed more reliable communications. Later the Benthos deck units were interfaced with the ships transducer instead of their cabled transducers, and this combination was used for all subsequent mooring operations. All mooring recoveries went relatively smoothly except for M417 (site WB5) which had a bad tangle near the mid-depth float. During breaks in the mooring work, PIES operations were conducted (one recovery and redeployment), and acoustic data telemetry at all 6 PIES sites on the Abaco line. Additional CTD casts (stations 25-27) were also conducted to provide post-deployment CTD data for PIES site A2 and post-recovery cal-dip data for the microcats retrieved from the moorings WB3 & WB5. After completing all work on the Abaco line, the ship completed the CTD/LADCP section (stations 28-32), on March 29-30. The ship stopped into West End on the morning of March 30 and then proceeded northward to the 27N line across the Straits of Florida. The final CTD/LADCP section (stations 33-41) was completed at 0300 on March 31.
