Afficher plus [+] Moins [-]An Autonomous Visual Plankton Recorder (AVPR) was used to record colour in situ images of plankton and other marine particulates at several oligotrophic stations around the world, including a northern hemisphere subtropical open ocean, a southern hemisphere tropical marginal sea, a northern hemisphere subtropical marginal sea, and a polar open ocean. Quantitative analyses and comparisons of particle concentrations, sizes and vertical profiles were possible after identification of optimal image enhancement settings and employment of a specially-developed macro routine in the off-the-shelf image analysis software Image Pro Plus. Marine particulate profiles, their relationships to oceanographic parameters and water mass structure, and the resolution-dependent limitations of the system are introduced and discussed
