Objectives1. To continue a seasonal series of measurements of physical (light, temperature, salinity), chemical (nutrients) and biological (phytoplankton, chlorophyll and zooplankton) variables.
2. To establish winter variables for primary production and bacterial (heterotrophic) production for comparison with summer/autumn determinations.
3. To determine the vertical distribution and abundance of the wintering copepodite stages of Calanus.
4. To obtain living material for length/dry weight, gut analysis, carbon, nitrogen content, lipids and extra-cellular enzyme activity of Calanus.
