The overall aim of the ECTZ, Islas Canarias, MAST Project 0031 is to improve the understanding of physical and biological phenomena in the region of the Canary Islands, which are located in a transition zone between the eutrophic upwelling waters of the African continental shelf and the oligotrophic oceanic waters of the Canary Islands. Data were collected on a cruise aboard the chartered Russian Research Vessel 'Ignat Pavlyuchkov' between 17 October and 5 November 1991. The general aim was to study the spatial and short-term temporal variability of properties characteristic of the autumn season in the area of the islands. Two large east-west transects were surveyed at the north and south of the islands, 45km spacing, sampled to 1000km depth, a fine grid sampled around Gran Canaria (20km apart) and two 24 hour fixed stations to the north and south of Gran Canaria were occupied (to 400km). Measurements were made of temperature, salinity, fluorescence, chlorophyll, oxygen, nutrients, primary production, particulate carbon and nitrogen, ETS, pigments, plankton and bacteria by means of CTD and Rosette water bottle casts (down to 1000m), Niskin water bottles and vertical and horizontal plankton tows. In addition, in situ carbon-14 studies were also carried out. This was a joint project involving UCNW, Universidad de las Palmas de Gran Canaria, Spain, Centro Oceanografico de Canarias, Spain and the Centro Comune de Ricerca, Ispara, Italy. UCNW was responsible for the data collected using the CTD (i.e. temperature, salinity and fluorometer and derived chlorophyll data). This data set comprises 117 CTD casts; 14 stations to the north of the Canary Islands; 11 station to the south of the Canaries; 41 stations on a fine grid and hourly vertical profiles at two sites.
