1. NARRATIVE

The vessel left Aden on 11 February, at 1600 hrs and steamed to Djibouti for refueling of diesel oil. After departure from djibouti the survey work started on the western part of the South Yemen coast, on 14 February. Eastward along the coast the shelf waters were surveyed with 10-15 nautical miles (18-28 km) between the transects. Near the shore the survey area was normally limited by the 15 or 20 m depth contour and seawards the transects stretched some nautical miles beyond the shelf edge into deep waters. The work was completed in the vicinity of the South Yemen/ Oman border on 22 February. A hydrographic section was worked along the route across the Gulf of Aden, between Ras Fartak and Socotra.

On 24 February the vessel called at Bosaso, where two scientists from Somalia embarked. The waters around Socotra were then surveyed, first the very narrow shelf along the northern coast and the work on the somewhat wider shelf south of Socotra was completed on 28 February.

A total of 51 trawl hauls were worked along the South Yemen coast and in the waters around Socotra. Of these, 45 were bottom trawl hauls and 6 were operated in mid-water with pelagic trawl.

Hydrographic observations were collected in two sections and 14 hydrographic stations were worked.

The work in Somali waters started on 28 February and the north eastern coast south to Ras Mabber, at 9°30' N, was surveyed. In addition, echo sounder observations were made along the northern coast of Somalia, on route to and from Bosaso. The survey work in Somali waters was completed on 4 March 1984.

A total of 24 trawl hauls were operated on the Somali shelf, 18 5 of which were bottom trawl hauls and 6 were worked in mid-water with pelagic trawl. Hydrographic observations were collected in two sections and a total of 9 hydrographic stations were worked.

On 4 March the vessel started steaming for Berbera to disembark the Somali scientists on 6 March. Due to illness, the scientist, Mr. Abdi Ismail Abdi, had to disembark at Bandar Beila on 2 March.

The scientists from South Yemen disembarked at Djibouti where the vessel called on 7 March. Due to break-down in an electric alternator, departure from djibouti was delayed till 10 March, 1600 hrs.

The vessel was cleared at Assab, Ethiopia, on 11 March and a naval security officer embarked together with the scientific staff. The work in Ethiopian waters started on 11 March. On 18 March the vessel was cleared at Massawa for work in the northern area and in the Massawa Channel. The Ethiopian personnel disembarked at Assab on 20 March.

The observations in the Ethiopian waters included 10 hydrographic stations and 25 trawl stations, all worked with bottom trawl.
