Sea Rover/SeaSoar basin scale traverses of the North Atlantic (1981-1991)Entry ID: BODC_NAtlantic_SeaRover
Abstract: As a major contribution to the UK World Ocean Circulation Experiment
(WOCE) Vivaldi was conceived as a series of seasonal surveys covering
the North Atlantic. In order to obtain both spatial coverage and high
resolution, a plan was developed for the Vivaldi '91 trial in which
nearly north-south SeaSoar sections (spaced 300km apart relative to
longitude 20deg W as origin) were complemented by deep ... CTD stations
every 3 degrees of latitude.
Vivaldi '91 (25 Apr - 10 Jun 1991) represented the first attempt to
carry out a systematic survey as suggested by the Vivaldi concept. The
survey was carried out in two parts, firstly a southeastern part from
Barry, UK to Ponta Delgada, Azores and then a western and northern
part from Ponta Delgada back to Barry. The area covered by the Vivaldi
'91 cruises was 39deg N to 54deg N, 12deg W to 34deg W. Thirty-three
sections of SeaSoar data were collected. The position of some of the
deep CTD casts was moved so that they would be in deeper water.
To complement these measurements, BODC has assembled the Sea Rover
data collected in the North Atlantic by the Institut fuer Meereskunde,
Kiel during the 1980s. The data coverage is as follows:
1981 5 sections and polar front box survey
1983 5 sections and polar front box survey
1984 6 sections
1985 3 sections
1986 4 sections
1987 2 sections
The sections vary in length between 500 and 1000 miles and the data
includes a number of repeated traverses between the Azores and the
Ocean Weather Ship at Station 'Charlie'.
The data originated with the Institut fuer Meereskunde, Kiel, Germany.
AVAILABILITY: Access to the data is currently restricted; contact BODC
for further details.
