Description:This document contains project instructions for EX-19-02. This cruise will be conducted 24 hours/day to perform shakedown operations of the deep-sea mapping and ROV systems in preparation for the 2019 field season. The expedition will commence on May 12, 2019 in Pascagoula, Mississippi (30° 20.355'N, 88° 34.499'W) and conclude on May 24, 2019 in Key West, Florida (24° 33.304'N, 81° 46.799'W). Operations are planned in the northeastern Gulf of Mexico along the edge of the west Florida escarpment and off the coast of Key West, FL.
Shakedown of ROV equipment will include a calibration of the ultra short baseline (USBL) positioning system, testing of a new suction sampler device, and three ROV engineering dives. Mapping shakedown will focus on calibrating the EM302 multibeam sonar (including backscatter calibration), calibrating the EK60/EK80 sonars, installing and testing the new Kongsberg K-Sync device, and troubleshooting the UnderwayCTD (UCTD) with the manufacturer’s representative. Some testing may also be completed on the ship’s dynamic positioning (DP) system. This expedition will be divided into 3 transit legs: May 12 - May 18, May 18 - May 22, and May 22 -May 24 (separated by small boat transfers). The first small boat transfer is needed to transfer off ROV Team members and to transfer on mission personnel needed to support EK60/EK80 calibration and Kongsberg equipment testing. The second small boat transfer is needed to drop off the Kongsberg technician and pick up a Teledyne technician.
