Ship name (ship code)RRS Challenger (74CH)
Cruise identifierCH66A
Cruise period1990-05-20 — 1990-05-31
StatusCompleted
Port of departureHull, United Kingdom
Port of returnHull, United Kingdom
PurposeResearch
Objectives1. To follow a set track around the southern North Sea making continuous measurements of:
(a) Sea surface temperature, conductivity and transmittance.
(b) Air/Sea fluxes
(c) Current profiles, with Challenger's acoustic doppler current profile (ADCP).
2. At 120 sites along the track:
(a) To record CTD profiles of temperature, conductivity and transmittance.
(b) To obtain water samples with a rosette sampler for calibration of the CTD conductivity and temperature sensors and to determine suspended sediment load.
3. To deploy moorings at:
(a) Sites A, B and C in the Dover Strait - a recording transmissometer and a 1 Mhz sea-bed ADCP at each site.
(b) Sites F and G - S4 current meters.
(c) Site H - thermistor chain and a 250 kHz sea-bed ADCP.
