The overall goal of this PICES project, funded by the Ministry of the Environment of Japan (MoE), was to assess and forecast the effects of this debris (termed Japanese Tsunami Marine Debris or JTMD), especially those related to non- indigenous species (NIS), on ecosystem structure and function, the coastlines, and communities of the Pacific coast of North America and in Hawaii, and to suggest research and management actions to mitigate any impacts. The project, referred to as ADRIFT (Assessing the Debris-Related Impact From Tsunami) focused on three main areas of research: (1) modeling movement of JTMD in the North Pacific, (2) surveillance and monitoring of JTMD landfall and accumulation, and (3) potential impacts from JTMD and associated NIS to coastal ecosystems in Pacific North America. The modeling group utilized a suite of general circulation models to simulate movement of marine debris arising from the Great Tsunami of 2011. The team developed, refined, and calibrated these models using available observational reports to forecast the distribution of JTMD and timelines of its potential arrival on the Pacific Coast of North America and in Hawaii. These results illustrated how different types of JTMD were transported – light-weight and/or floating debris are transported rapidly and may be removed from the ocean within a year following the tsunami (e.g., polystyrene), while heavy-weight and/or submerged/sunken debris can remain in the ocean considerably longer, with the potential to become entrained in the North Pacific gyre (i.e., garbage patch). Simulated particles reaching the coasts of Washington and Oregon showed a strong seasonal cycle. The models were used to calculate probable trajectories of individual JTMD items to highlight areas where debris was likely to accumulate, as well as probable oceanographic conditions (temperature, salinity, and chlorophyll) along the JTMD trajectories to facilitate NIS risk assessments. The surveillance and monitoring team characterized the temporal and spatial variability in JTMD landfall in North America and Hawaii and its relationship to the reported debris resulting from the Great Tsunami of 2011. Aerial photographic surveys were conducted for the main Hawaiian Islands and the outer coastline of British Columbia, Canada. Analysis of the monitoring data showed a sharp increase in the influx of debris items beginning in May 2012; indicator items, such as beverage containers and other consumer items, increased 10 times over records prior to the tsunami. A webcam system was installed at a site in Oregon during February 2015 to track beach-specific debris landings and removals to better understand temporal dynamics of debris on coastal beaches. The NIS team characterized the invasion potential of species associated with JTMD by 1) documenting the biodiversity allied with arriving JTMD objects, 2) formally evaluating the risk of the species and JTMD as a vector for NIS overall, and 3) conducting detection surveys in Pacific PICES/MoE ADRIFT Project iii Executive Summary North America and Hawaii. Over the course of the project, 650 JTMD items have been intercepted and sampled, from which more than 380 species of algae, invertebrates and fish have been identified. With time, fewer
