| 英文摘要 | The purpose of RRS James Cook cruise JC145 was to refurbish the RAPID 26掳N array of moorings that span the Atlantic from the Bahamas to the Canary Islands. Cruise JC145 departed from Santa Cruz de Tenerife on Tuesday 28th February 2017 and ended on Saturday 8th April at Freeport, Bahamas. There was a port call at Nassau, Bahamas on 27th March to exchange personnel and to take on board additional equipment. The moorings are part of a purposeful Atlantic wide array that monitors the Atlantic Meridional Overturning Circulation and the associated heat transport. The RAPID-MOCHA-WBTS array is a joint UK- US programme. During JC145 moorings were serviced at sites: EBH4, EBH4L, EBH3, EBH2, EBH1, EBH1L, EBHi, EB1, EB1L, MAR3, MAR3L, MAR2, MAR1, MAR1L, MAR0, WB6, WB4, WB4L, WBH2, WB2, WB2L, WB1, WBADCP and WBAL. Sites with suffix 鈥楲鈥?denote landers fitted with bottom pressure recorders. The ABC Fluxes project extends the measurements on the RAPID 26掳N array to include biological and chemical measurements. Cruise JC145 was the first recovery of these instruments and another set were deployed to continue measurement until autumn of 2018. CTD stations were conducted throughout the cruise for purposes of providing pre- and post- deployment calibrations for mooring instrumentation (including oxygen and carbonate chemistry sampling) and for testing mooring releases prior to deployment. The RAPID telemetry MkIII system was recovered from site EBHi, and 24 temperature sensors and 2 75kHz ADCPs were recovered from mooring WB1 for the MerMEED project. Shipboard underway measurements were systematically logged, processed and calibrated, including: surface meteorology, 5m depth sea temperatures and salinities, water depth, and navigation. Water velocity profiles from 15 m to approximately 800 m depth were obtained using two vessel mounted Acoustic Doppler Current Profilers (one 75 kHz and one 150 kHz). |
