Description 
Summary

Twelve cruises of between 80-130 stations were undertaken to describe the distribution, mortality and drift of fish eggs and larvae. All fish eggs and larvae were identified to species where possible. Edible crab (Cancer pagurus) and Nephrops larvae were counted and staged. Densities of each species were calculated to numbers per square metre and contoured charts (hand drawn) were produced. Most of these data are on MAFFMAP (as part of the UK Digital Marine Atlas), available on floppy disk. Environmental parameters were measured as follows: continuous records of surface temperature, salinity, pH, dissolved oxygen and transparency; surface salinity is also available from bottle samples on each sampling position; nutrient samples (nitrate, nitrite, phosphate and silicate) were taken from surface water on each sampling position; continuous measurement of in-vivo chlorophyll-a fluorescence.
