Processed CTD continuous observations from the Coastal Current Meter Programme on the Africana Voyage 017, March 1984

This is processed downcast Conductivity-Temperature-Depth (CTD) continuous data from the Coastal Current Meter Programme on the Africana Voyage 017 collected between 19 and 27 March 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. The objectives of this cruise were to retrieve ten moorings, eight on the shelf and two on the shelf break between Cape Columbine and Port Nolloth; to deploy three moorings in the coastal zone between Cape Columbine and Cape Town; to obtain Conductivity-Temperature-Depth (CTD) profiles and water samples on a transect bearing 270° from Cape Columbine; to profile currents, make repeated CTD casts and record atmospheric conditions in St Helena Bay as part of a vertical mixing study, participating in this work were two scientists from UCT; to calibrate the CTD temperature probe in-situ using reversing thermometers; to allow the chemical oceanography team to familiarise themselves with...

Processed CTD continuous observations from the West Coast Physical Oceanography cruise on the Africana Voyage 016, February 1984

This is processed downcast Conductivity-Temperature-Depth (CTD) continuous data from the West Coast Physical Oceanography cruise on the Africana Voyage 016 collected between 03 and 04 February 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. The objectives of this cruise were to conduct torsional vibration trials to meet the requirements of Lloyds, to retrieve and deploy two thermistor chain/current meter moorings and to conduct CTD profiling in the area of operations.

Processed CTD discrete observations from the West Coast Physical Oceanography on the Africana Voyage 025, October 1984

This is processed Conductivity-Temperature-Depth (CTD) discrete data from the West Coast Physical Oceanography on the Africana Voyage 025, collected between 25 and 31 October 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. The objectives of this cruise included studying shelf circulation in the vicinity of Port Nolloth by placing three current meter moorings across the shelf; exploring the deep circulation in the Cape Basin which is thought to be a driving mechanism for the preponderance of southward flow observed on the shelf by placing a current meter in 3000m of water; recovering one current meter in the Cape Canyon and deploying two current meter moorings and a thermistor string near Cape Columbine and obtaining Conductivity-Temperature-Depth (CTD) data at these sites; collecting chemical samples and CTD data along a line between Port Nolloth to the deep current meter site, this included 100ml samples...

Processed CTD continuous observations from the Physical-Chemical Oceanography Cruise on the Africana Voyage 077, September 1989

Here we present processed downcast Conductivity-Temperature-Depth (CTD) continuous data collected between 11 September and 22 September 1989 during Voyage 077 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of Southern Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000. There were several objectives for the Physical-Chemical Oceanography Cruise, covering Physical Environment (PE), Sedimentation and Nutrient cycling (SN), Chemical Environment (CE), Shoal Ecology (SE), Plankton studies (P) and testing of the new AIDA acoustic system with possible estimates of biomass in specific places such as in the baroclinic jets. The objectives included identifying and documenting near-surface and mid-water baroclinic jets west of Cape Columbine and Cape Town using acoustic doppler profiling and...

Processed CTD discrete observations from the Coastal Current Meter Programme on the Africana Voyage 017, March 1984

This is processed Conductivity-Temperature-Depth (CTD) discrete data from the upcast from the Coastal Current Meter Programme on the Africana Voyage 017 collected between 19 and 27 March 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. The objectives of this cruise were to retrieve ten moorings, eight on the shelf and two on the shelf break between Cape Columbine and Port Nolloth; to deploy three moorings in the coastal zone between Cape Columbine and Cape Town; to obtain Conductivity-Temperature-Depth (CTD) profiles and water samples on a transect bearing 270° from Cape Columbine; to profile currents, make repeated CTD casts and record atmospheric conditions in St Helena Bay as part of a vertical mixing study, participating in this work were two scientists from UCT; to calibrate the CTD temperature probe in-situ using reversing thermometers; to allow the chemical oceanography team to familiarise themselves...

Processed CTD discrete observations from the Physical-Chemical Oceanography Cruise on the Africana Voyage 067, September 1988

Here we present processed Conductivity-Temperature-Depth (CTD) discrete data from the upcast collected between 14 and 30 September 1988 during Voyage 067 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of Southern Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000. The Physical-Chemical Oceanography Cruise was divided into two legs with the first leg focusing on physical oceanography and the latter on chemical oceanography. The purpose of the first leg of the cruise was primarily to moor current meters and water-level recorders at various sites, mostly north of the Orange River, and to obtain a precise set of Conductivity-Temperature-Depth (CTD) data on a line running normal to the topography from a point in 4200m of water into Conception Bay. The CTD data will be used to calculate water...
