Abstract:
Structure of mesoplankton and distribution of dissolved ammonia in the vicinity of an isolated seamount of the Louisville Ridge in the subantarctic zone of the Pacific Ocean was studied using data obtained in January 1985 in an area 20 x 30 nm. There were areas with both high (20-25 to 139 g/m**2 in the 0-200 m layer) and low biomass values (<10 g/m**2) of mesoplankton. In the areas with high biomass, a single species Calanus tonsus was strongly dominant (>80% of biomass); its population was relatively mature in seasonal terms, with relatively high percentage of individuals containing fat inclusions. Stations with high mesoplankton biomass also had relatively high concentrations of dissolved ammonia. Presence of plankton-rich areas corre¬lated with presence of a quasi-steady-state topographic eddy. Lifetimes of these nonuniformities in the structure of mesoplankton are estimated as 10-30 days.
