PurposeResearch
ObjectivesThe AMT11 cruise sailed from Grimsby in the United Kingdom on 12th September 2000, and ended in Montevideo, Uruguay on October 11th.
The long-term objectives of the AMT programme are:
1. To better understand the links between biogeochemical processes, biogenic gas exchange, air-sea interactions and the effects on and the responses of oceanic ecosystems to climate change.
2. To investigate the functional roles of biological particles, and the processes that influence ocean colour in ecosystem dynamics.
3. To develop algorithms and the validation of remotely sensed observations of ocean colour.
As previously the cruise was centred close to 20 degrees West for the southern transect in the northern hemisphere, the track then deviated to the east to carry out the BAS swath bathymetry research survey (refer to cruise report JR53), which was essentially a cruise within the AMT whose main objective was to survey an 80 km section of the Mid-Atlantic Ridge. Following this work, the cruise transect headed south-westerly past Ascension Island across the south Atlantic gyre, and on to Montevideo, Uruguay.
During AMT11 and JR53, work was undertaken to test and develop the AutoFlux air-sea interaction system amd its assocaited prototype instrumentation. The system is intended to provide real-time air-sea fluxes of momentum, sensible heat, latent heat and CO2 in addition to meteorological parameters. Work on this system continued on the subsequent cruise from 11 Oct to 17 Oct 2000 between Montevideo, Uruguay and Stanley, Falkland Islands (JR52 Leg2, JR20001013).
