The objective of this study was to investigate the production of Calanus helgolandicus off Plymouth, Western English Channel, from April to August 1998 comparing a range of different methods. The abundance of all developmental stages from NI to adult

Mesozooplankton distribution and copepod grazing were investigated in the Subtropical Atlantic Ocean near the Azores during the AZORES I (August) and II (April-May) cruises. Mesozoo- plankton biomass and abundance remained low throughout the region,

Zooplankton biomass and the carbon content of vertical migrants were measured in the NE Atlantic (36.53N, 19.23W) between 11 and 18 July 1996 as part of the Plankton Reactivity in the Marine Environment (PRIME) programme. The increase in zooplankton

To investigate possible reasons for the discrepancy between the abundance of 4-methyl components in free sterols and steryl chlorin esters (SCEs) which is commonly observed in sediments, experiments in which the copepod Calanus helgolandicus grazed o

The temporal distribution of autotrophic and heterotrophic components of the planktonic community was studied from samples collected weekly at station L4, located to the south of Plymouth, UK, from October 1992 to January 1994. Phytoplankton successi
