Objectives and Narrative |
JR276 was part of DIMES, "Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean", a joint UK and US project funded by the National Science Foundation in the US and NERC in the UK. The objective of DIMES was "to test and, if necessary, redefine the present paradigm of Southern Ocean mixing by obtaining the first systematic measurements of mixing processes in two contrasting regimes (the SE Pacific and the SW Atlantic) of the Antarctic Circumpolar Current (ACC)".
The methods of relevance to this cruise were: (1) the release of an inert chemical tracer, CF3SF5 (tri-fluoromethyl sulphur pentafluoride) in the SE Pacific sector west of Drake Passage and following its dispersion horizontally and laterally as it transits the SE Pacific, Drake passage and the Scotia Sea (2) The use of fine structure and microstructure measurements from Lowered ADCP, CTD and free-falling microstructure probes (3) the release of surface drifters and neutral density floats. This cruise took place about two years after the experiment was initiated by release of tracer and floats in the SE Pacific. Its specific objective was to observe the distribution of tracer and make measurements of turbulence on sections either side of Drake Passage, to quantify the mixing taking place in that region. The western section was along 78°W in the SE Pacific sector of the Southern Ocean, from 56.5°S to 64°S. It comprised 38 CTD and water bottle rosette stations, at various spacings but with those between 60° and 62° being very closely spaced, about 1/8 degree. The eastern section was along part of the CLIVAR repeat hydrography SR1 line, from 59°S 55.85W, to 55.14°S 58°W, with 14 CTD /rosette stations, about every 20 nautical miles. Vertical microstructure profiles were also measured on a total 14 of the stations, using a free-falling instrument manufactured by Rockland Scientific. Thirteen surface drifters and six subsurface RAFOS floats were released in clusters at two locations on the cruise track between the two sections, to study the evolution of Lagrangian coherent structures in the velocity field and their role in mixing Underway data (surface TSG, met, ADCP and swath bathymetry) were collected continuously once the vessel had left Chilean waters, just before the first station on the S3 line. |
