RV Cirolana CIR5/76
Cruise summary report
|Ship name (ship code)||RV Cirolana (74CZ)|
|Cruise period||1976-04-21 — 1976-05-14|
|Port of departure||Grimsby, United Kingdom|
|Port of return||Grimsby, United Kingdom|
1. To service the North East Coast (NE 1-4) and JONSIS (J1-2) moored current meter stations (JONSDAP 76 stations 33, 34, 28, 29, 30 and 31 respectively.
2. To recover:
a) the Lowestoft-Denmark moored current meter stations laid during CIROLANA 3/76 (JONSDAP 76 stations 35-45);
b) the DAFS Aberdeen moored current meter stations laid in early March (JONSDAP 76 stations 46-521).
3. To re-launch the current meters supplied by Denmark at a station inside the FLEX square.
4. To put in hand during passage between current meter stations but especially during hours of darkness one or more of the following operations:
(a) Continuous surface temperature and chlorophyll-A measurements with particular reference to a run between the Farne Islands and the coast of Northumberland.
(b) Particle-size counting.
© A series of runs at 5 knots during which chlorophyll-A, temperature and particle size will be monitored.
(d) Grab sampling for superficial benthos.
(This work forms part of the North East Coast project which, at
this time of the year, is a sub-set of the FLEX phase of JONSDAP 76.)
(i) To sample conditions between Aberdeen arid the FLEX box with the continuous plankton recorder (CPR) .
(ii) To steam round the FLEX box grid at 5 knots:
(a) monitoring conditions with the High Speed Loch Ewe (HSLE)
plankton sampler during the period 7-10 May;
(b) a little way behind RV EXPLORER for as long as possible in the period 11-15 May comparing measurements of near-surface chlorophyll-A, temperature, salinity and nitrate;
(c) to sample several stations on the grid for a variety of hydrographic and biological parameters.
