AMT18
This was the
eighteenth in the series of Atlantic Meridional Transect cruises
and was carried out on board the British Antarctic Survey research
vessel, the RRS James Clark Ross.
The cruise sailed from Immingham in the UK on 4 October
2008 and ended in Port Stanley, Falkland Islands, on 10 November
2008.
This was the first of the series of AMT cruises funded through
Theme 10b of the NERC Oceans 2025 science programme, which is a
scientific collaboration between the Plymouth Marine Laboratory and
the National Oceanography Centre, Southampton.
Measurements taken on the cruise included hydrographic, chemical,
ecological and optical data. Many of these measurements were
made in underway mode (either via towed instruments or those
connected to a sea water supply on board) with minimum personnel
intervention. Depth profiles of temperature and salinity were
taken daily, both pre-dawn and mid-morning usually to a maximum
depth of 300m. Boundaries between upper ocean water masses
were determined by the position of current jets and compared with
near real-time satellite images and upper ocean density
measurements.
