Cruise period1990-06-29 — 1990-07-22
StatusCompleted
Port of departureGreat Yarmouth, United Kingdom
Port of returnAberdeen, United Kingdom
Objectives1. To observe the path of the overflow water in the Iceland Basin on the south side of the Iceland Faroes Ridge using a lowered CTD, XBTs and ship mounted ACDP (Acoustic Dropper Current Profiler)/
2. To determine the chemical properties (nutrients, dissolved oxygen and aluminium concentration) of the Overflow and Atlantic water masses.
3. To deploy an array of moored current and temperature recorders south of Iceland
4. To deploy a moored ACDP on the Iceland-Faroes Ridge in support of Charles Darwin Cr51
