Cruise period1977-03-14 — 1977-03-26
StatusCompleted
Port of departureBarry, United Kingdom
Port of returnLiverpool, United Kingdom
ObjectivesFirst in a 2-cruise experiment to determine the residual current field in the Eastern Irish Sea using an array of moored current meters, deployed together with an array of bottom-mounted tide-gauge/current meters to determine tidal friction. This cruise deployed the moorings as well as collecting supporting underway temperature/salinity and CTD data.
