Behavior of Pumped-up Deep Seawater and Fertilization Effects: Feasibility Study of Free-drifting Buoy and a CTD/Chlorophyll Vertical Profiling Vehicle

Abstract

In order to evaluate a behavior and fertilization effects of pumped-up deep seawater into an euphotic zone, free-drifting buoy experiments on tracking a naturally-occurring upwelling and an artificially pumped-up deep seawater were reviewed. Preliminary experiments of an autonomous profiling vehicle having CTD/Chl sensors was also conducted at a shallow coastal sea.
