(Table 1) 100 m integrated temperature, chlorophyll a content and protist biomass during Leg 7 of Galathea 3 cruise (2006)
We present a study on the protozooplankton >5 µm and copepods larger than 50 µm at a series of contrasting stations across the Southern Indian Ocean (SIO). Numerically, over 80% of the copepod community across the transect was less than 650 µm in size, dominated by nauplii, and smaller copepods,...

We present a study on the protozooplankton >5 µm and copepods larger than 50 µm at a series of contrasting stations across the Southern Indian Ocean (SIO). Numerically, over 80% of the copepod community across the transect was less than 650 µm in size, dominated by nauplii, and smaller copepods, while 80% of the biomass (as mg C/m**3) was larger than 1300 µm in body length. Predation by the carnivorous copepod Corycaeus sp. was estimated to be able to remove up to 2% /d of the copepods <1000 µm in size. By the help of grazing models we estimated that primary producers were mainly grazed upon by ciliates and heterotrophic dinoflagellates (40-80% /d combined) in temperate waters but appendicularians became increasingly important in the tropical waters grazing about 40% of the biomass per day.
