| Status | Completed |
| Port of departure | Aberdeen, United Kingdom |
| Port of return | Aberdeen, United Kingdom |
| Purpose | Research |
| Objectives | 1. To make hydrographic and plankton measurements in the Firth of Forth (27 - 31 October, 17 - 21 November) and in Sullom Voe and the JONSIS line (10 - 14 November).
2. To lay and recover 4 current meter moorings in the Firth of Forth. 3. To evaluate the Inter Ocean STD system. A grid of stations were worked to collect samples for salinity, nutrient, and trace metal analysis, and for plankton analysis at the Firth of Forth. A section down the axis of the Voe was worked and an anchor station near the mouth of Orka Voe was worked using the N10 TS bridge and the direct reading current meter. Trials of the STD system were begun and were contiued in the southern Moray Firth. On reaching the Forth, calibration samples for heavy metal analysis were collected. |
