The samplings were taken with the WP-2 closing net and the WP-2 modified net. The type of tows was vertical. The WP-2 closing net had a mesh size 200µm and a net mouth diameter 57cm. The tow speed was 1m/s and the filtered water volume was estimated by the net mouth surface and the towing distance. The WP-2 modified net had a mesh size 45µm and a net mouth diameter of 50cm. The tow speed was 0.5m/s and the filtered water volume was estimated by the net mouth surface and the towing distance.
Egg production rates of the dominant calanoid copepods were determined by incubation of fertilised females (eggs female-1 d-1) collected in the 0-100m layer. Copepod egg production was measured for the copepods Acartia clausi, Paracalanus parvus and Centropages typicus. On board experiments for the estimation of copepod egg production were taken place. For the estimation of copepod production (mgC m-2 d-1), lengths (copepods and eggs) were converted to body carbon (Hopcroft et al., 1998) and production was estimated from biomass and weight-specific egg production rates, by assuming that those rates are representative for juvenile specific growth rates (Berggreen et al., 1988), see:
