Physical Forcing of Zooplankton in the Upper Oligotrophic Ocean Off Bermuda (northwestern Atlantic) and New Caledonia (southwestern Pacific) from Acoustics and Net Measurements

Book Description
Physical forcing drives the space and time discontinuity (patchiness) of plankton in the ocean. The thesis was focused on the role of these forcing on the zooplankton, studied using both acoustic and traditional methods with net sampling. The study was based on two examples. The first one concerns the northwestern Sargasso Sea where high resolution time-series data on 0-200m macrozooplankton abundance and distribution off Bermuda was estimated from volume backscattering strength (Sv) measured with a 153-Khz ADCP. Three types of eddies were identified: a productive cyclonic eddy, the periphery of a mode water eddy, and the periphery of an anticyclonic eddy. Sv values increased during passage of theses eddies, with a more pronounced increase associated with the edge of the cyclonic and the anticyclonic eddies, suggesting a significant biological response to localized upwelling in the high velocity boundary of these eddies. In the second example, spatial and temporal distribution of zooplankton off New Caledonia was studied during two multidisciplinary cruises in 2011. Zooplankton variability was assessed using net sampling together with acoustic measurements (shipborne ADCP, scientific echosounder and TAPS). Higher amplitudes of diel vertical migration (DVM) of zooplankton were associated with higher abundance of large zooplankton and cold waters to the south of the study area, while lower DVM amplitudes in the north were associated with warmer waters and higher abundance of small organisms. These acoustic measurements clearly evidenced the role of physical forcing, particularly mesoscale features, in shaping zooplankton space and time distribution.
