Narrative Documents
Data Processing Notes
This document pertains to the wind data collected by RRS Discovery during the Upwelling 75 experiment.
Wind speed and direction have been derived from hourly vector means of the ship's acquisition system which sampled at one second intervals.
The winds were recorded as the ship was positioned for working hydrographic stations along the A and B lines. These lines were orientated at 37° and 13° respectively to the E W co-ordinate.
- Line A passed through 24° 54min N 15° 31min W and through 25° 45min N 16° 50min W.
- Line B passed through 22° 41min N 16° 36min W and through 23° 07min N 18° 17min W.
The ship worked along these lines as follows:
- 2 to 5 February line B
- 6 to 8 February line A
- 9 to 12 February line B
- 13 to 16 February line A
- 17 to 20 February in port, Santa Cruz de Tenerife
- 21 February line A
- 22 February to 3 March line B
The format of the originator's reference, when quoted by BODC, is mooring number/instrument number.
Project Information
UPWELLING 75 - AUFTRIEB 75
This project was organised jointly by the U.K. Institute of Oceanographic Sciences, the Department of Oceanography of the University of Liverpool and the Institut für Meereskunde of the University of Kiel. Scientists from the Marine Science Laboratories, Menai Bridge, the Department of Applied Mathematics and Theoretical Physics of the University of Cambridge and the Institute of Physical Oceanography of the University of Copenhagen also took part in the cruise. There was an interchange of British and German scientists between the research ships, R.R.S. Discovery and F.S. Meteor.
The aim of the project was to study the physical, biological and chemical processes involved in upwelling off the NW African coast, with particular emphasis on the measurement of onshore/offshore and longshore water movements and the relationships of phytoplankton, zooplankton and micronekton distribution to them.
Three lines of stations normal to the coast were established with current meter moorings on each. Discovery worked line A in 25° N and line B in 22° 40' N and Meteor worked line B and line C in 21° 20' N. There were ten nominal hydrographic station positions on each line. STD and water bottle surveys were made of the lines and nets were fished on two of the surveys of each line.
