|Seston||Quantity: sample litres = 69200000|
Description: Litres of seawater sampled for plankton from all of the MlK net and Gulf III stations
|Seston||Quantity: number of hauls = 38|
Description: GULF III samples taken for plankton during daylight hours. Plankton samples were fixed in 4% buffered formaldehyde and stored.
|Eggs and larvae||Quantity: number of hauls = 19|
Description: Fish and Nephrops larvae were removed from the MIK net samples and fixed in 4% buffered formaldehyde
