Field survey, Research Cruise
Overview
Overview of the Observation Topographic survey During the cruise, bathymetry data off Fukushima, Miyagi, Iwate is obtained by SEABAT. Marine environmental information is acquired by XCTD casting and ADCP measuring. 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, and for comparing biodiversity between in and outside of the deep-sea canyon off Kamaishi Biological sampling for estimating parameters of the ecosystem model. As the candidates of functional groups of Ecopath model, ophiuroids, dahlia anemone, and other benthic animals are collected for stomach contents analysis.
