ObjectivesSecond 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 recovered the moorings as well as collecting supporting underway temperature/salinity and CTD data.
