Objectives1. To sample the zooplankton of the northern Irish Sea, to estimate the distribution and abundance of Nephrops larvae, being the first of four surveys contributing to the estimation of spawning female biomass.
2. To study the vertical distribution of Nephrops larvae using the Longhurst-Hardy Plankton recorder (if time allows). Due to the protracted passage out, there was no time to deploy the LHPR.
3. To survey the variation in the surface seawater of temperature, salinity, nitrate, phosphate and silicate.
4. To collect water samples for caesium estimation for AEPD.
5. Additional aim: to locate and recover a nearbed velocity rig off Southwold.
