Research Information

Period and Interval
2017/02/11 - 2017/02/27
Research Area
Off Sanriku
Category
Field survey, Research Cruise
Overview
Overview of the Observation Topographic survey During the cruise, bathymetry and SBP data off Fukushima are obtained by SEABAT and TOPAS PS 18 System. Quantitative observation of benthic animals and debris using the bottom observation camera system The quantitative biomass of benthic animals and mass of marine debris are observed by the main HDTV and the bottom observation camera systems loaded on the rear of the Hyper-Dolphin for establishing the habitat models. Biomass estimation of scavengers and predators Three types of baited cameras are deployed off Sanriku for estimating biomass of scavengers and predators attracted to the bait, contributing to establishing the ecosystem models.
