Processed CTD continuous observations from the Algoa Voyage 234, January 2017

SeaBird SBE911 plus Conductivity-Temperature-Depth (CTD) instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises from 2000. Here we present processed downcast CTD continuous data collected, between 13 January and 11 February 2017, during Voyage 234 on the RV Algoa, in the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of South Africa.

Anchovy Spawning Stock Survey on the Africana Voyage 038, November 1985

The objectives of this cruise were to assess the size of the anchovy spawning stock in Cape waters by acoustic survey and estimation of egg production; describe the distribution and behaviour of other pelagic and mesopelagic fish of commercial importance; describe anchovy spawning patterns and estimate the precision of the parameters used in assessing spawning stock size by the egg production method (sex ratio, spawning fraction, fecundity, mean weight); and to investigate relationships between the distribution of pelagic fish, eggs and water temperature.

South Coast Hake Biomass on the Africana Voyage 036, October 1985

The first objective of this cruise was to establish, by means of surveying and trawling between 200m and 500m water depths, the feasibility of extending the hake biomass surveys to the South Coast. The area 20 E to 25 E, from 75m to 200m water depths, has already been covered during biomass surveys by Japanese research vessels, accompanied on each occasion by one of the Institute's scientists. The feasibility of trawling shallower than 200m in this region, albeit with heavy gear, has thus already been established. The second objective was to investigate, by trawling, the depth distribution of squid in the area 23 30'E and 24 30'E, from as close as possible to the coast (i.e. as shallow as possible) to a depth of 500m.

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 for analysis by M.J. Orren on routine CTD casts; a line of six coastal CTD stations was to be worked in the Hondeklipbaai upwelling tongue; the surface flow over the 1000m contour was to be studied using an acoustic drifter and samples were to be taken at various CTD stations for nitrogen cycling studies.
