Dataset includes associated positional data and sample volumes filtered of the plankton stations.

Both nets had flowmeters (General Oceanics mechanical flowmeters with standard rotor, model 2030R) mounted in the centre of the "mouth" and a min CTD (SAIV) was attached to the bridle. A rosette with a CTD was deployed prior to the ring net deployment to provide *in situ* information on the presence (and depth) or absence of the thermocline. As it was assumed that fish eggs of pelagic species float above the thermocline layers, the plankton nets were only deployed to the depth of the thermocline or, if absent, down to just above the seabed. Position, date, time seabed depth, angle of the net, sampled depth (from CTD attached to net) and flowmeter readings were recorded. Samples were transferred from the "bag ends" in to 1 lb glass jarsand preserved with 4% buffered formaldehyde. MEDIN 3.1.1
