This dataset is the register of debris items collected during the project. It includes the item's registry code number, the type of debris (dock, float, vessel, etc.), the name of the debris and boat name if available, its origin in Japan, the location collected, and the date found.
Access to this data is RESTRICTED for the duration of the project funding period (through 2014).

| Description | Japanese tsunami marine debris collection |
I. Biodiversity; Population and Food Web Analysis; Viability and Reproductive Condition; Dispersal Track and Growth History; Shellfish Pathogens/Parasites
This project seeks to document the biodiversity of Japanese species on arriving tsunami-generated debris, through morphological and genetic identification (including massively parallel DNA sequencing of whole community samples) andthrough quantitative replicate samples to determine numerical abundance, density, frequency, and biomass. In addition, species accumulation and rarefaction curves will be determinded to estimate total inbound diversity.
Focuses include:
- Population structure of selected taxa, based on size/age class distributions.
- Viability and reproductive condition of selected taxa, based on fecundity, gonadal indices, and/or spore production, upon arrival.
- Food web analyses based upon tissue stable isotope ratios (δ13C and δ15N).
- Dispersal track and growth history of selected taxa based on oxygen isotopic and elemental composition of shell calcite.
- Identity and prevalence of parasites and pathogens in oysters (Crassostrea gigas) and mussels (Mytilus galloprovincialis).
II. Biotic Attrition Over Time
Comparison of dead species assemblages on JTMD to live assemblages to assess the fate and alteration of debris communities over time.
III. Genetic Matching of Novel Invasions With JTMD Biota
Genetically characterize populations of target species so that if and when new invasions are detected, or when previously established invasions appear to be newly expanding or appearing in new locations, genetic studies can be undertaken to determine if these events are related to the JTMD phenomenon.
This is a Rapid Response Grant.
