The objective of cruise DY039 was to service the moorings of the RAPID 26°N project that are deployed to monitor the Atlantic Meridional Overturning Circulation. For each mooring instruments were recovered, data were downloaded and instruments were redeployed. A number of CTDs were made to calibrate the instruments from the moorings. In addition to the standard instruments used in previous years on the RAPID array, biogeochemical instruments were deployed for the ABC Fluxes project, along with some additional temperature sensors and ADCPs for the MerMeed project. During passage from Southampton to Tenerife trial CTDs were completed in international waters. After a short port call in Santa Cruz de Tenerife, departing on the 26th October work commenced on the eastern boundary sub-array comprising of moorings EBH4, EBH4L, EBH3, EBH2, EBH1, EBH1L, EBHi, EB1 and EB1L. A lander was deployed alongside EBHi to provide delayed-mode data telemetry through timed data pod release. Work on the MAR sub-array commenced on 7th November at mooring MAR3. The other moorings in this sub-array (MAR3L, MAR1, MAR1L, MAR2 and MAR0) were all completed by 12th November. The NOG mooring was also recovered and redeployed as part of the MAR sub-array servicing. Mooring WB6 was serviced on 19th November before transiting to Nassau for customs clearance. The remaining western boundary sub-array moorings (WBADCP, WBAL, WB1, WB2, WB2L, WBH2, WB4 and WB4L) were serviced between the 22nd November and the 30th November before docking in Nassau on the 1st December.

The overall objective of the cruise was to perform a systematic geophysical survey. The principal aim is to obtain complete bathymetric sea-floor coverage. There are other geophysical data obtained during the cruise, whose acquisition is compatible with the navigation requirements of the multibeam survey, such asgravity, geomagnetic and ultra-high resolution seismic data (TOPAS system).This project id the result of a cooperation between the Instituto Hidrografico de la Marina (IHM, Hydrographic Institution of the Spanish Navy) and the Real Observatorio de la Armada (ROA, Royal Observatory of the Spanish Navy), under the control of the Secretaria General Tecnica del Ministerio de Defensa (SEGENTE, General Technical Secretary of the Spanish Defense Department), whith the collaboration of several other institutions and universities.The cruise started on September 3rd at Santander and finished at La Coruña on September 27th. It was planned in order to cover two bathymetric charts (G7 and G8) to the NW of the Galicia Bank, but the good course of the works allowed to go beyond this first objective and finalize also chart G9, which was only partially covered during ZEE-2003 cruise.
