|Cruise period||1997-04-04 — 1997-04-10|
|Port of departure||Belfast, United Kingdom|
|Port of return||Belfast, United Kingdom|
|Objectives||The two objectives of this cruise were to study the coupling between primary and secondary production at the start of the spring phytoplankton bloom and quantify the flux of particulate organic carbon to the benthos. Detailed objectives were to:
1. Quantify phytoplankton production in two size fractions (whole and <5.0 um).
2. Quantify the impact of zooplankton grazing on the phytoplankton community.
3. Collect samples of phytoplankton and zooplankton for later identification and enumeration.
4. Collect sediment samples for the determination of sediment pigment concentration.
5. Collect water samples for the determination of particulate aluminium and dissolved inorganic nutrients.
6. Service the DANI moorings.
