Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
PurposeResearch
Objectives1 To service the three Lowestoft long-term moored current meter stations
of the ICES North Sea network.
2. To establish short-term moored current meter stations
(i) Between the stations of the existing long-term German-UK line
that stretches north-eastwards from Flamborough Head to the
German Bight;
(ii) Between the existing German station and the Danish coast;
(iii) In a line between Lowestoft and the Dutch coast.
The data from these stations will provide much greater detail in
the short-period than is normally available at the open boundaries
of the MAFF mathematical model.
3. To establish 3 moored current meter stations for at least 12.5 hours
around the AMOCO drilling platform sited near the Indefatigable
Bank. The data from these stations will be compared with that given
by instruments hanging from the platform to see if the rig structure
is seriously affecting the flow patterns found in the open sea.
4. To establish 3 moored current meter stations relatively close
inshore between Yarmouth and Southwold that will provide
complementary data for Mr Talbot's concurrent diffusion cruises on
the RVs TELLINA and NUCELLA.
5. To measure currents at 4 metre intervals throughout the water
column for at least 12.5 hours at anchored stations close to each
of the Lowestoft ICES stations.
6. To try to identify by means of a detailed temperature and salinity
survey the position of the South West Dogger Bank gyre relative to
the moored stations.
7. To begin an immersion test of part of the MAFF acoustic release.
