Abstract
The Tohoku Ecosystem-Associated Marine Science (TEAMS) project
started from 2011 with the aim of revealing the impacts of the 2011 tsunami and to assess the present state of the marine ecosystem in affected
areas over time during the next decade. TEAMS collected various data
such as bathymetry, geography, oceanography, benthos, and tsunami
debris not only from our project but also from the archived data at our
respective institutes and in public databases. Integration of data and creation of habitat maps are expected to contribute to our understanding of
the effects of large tsunamis, present the status of marine biodiversity in
the area, and lead to the identifi cation of key areas for ensuring ecosystem
resilience. Here we focus on information of marine debris identifi ed from
deep-sea images and sonar data. We conducted data integration and collated information in a GIS database.
Our preliminary results suggest that the impact of the tsunami debris in
deep-sea areas (ca. 200–500 m) was not as severe as in coastal environments. Accumulations of tsunami debris were found mainly in submarine
canyons. Although different types of debris occur so far in mixed aggregations, differences in the movement and decomposition patterns of these
different materials are expected to lead to both positive and negative
effects on the environment in different ways.
