Sample log of debris collected from available JTMD items to assess species diversity, total abundance, density, and biomass. Information in this log includes sample identification numbers, date collected and date the sample arrived for analysis, the method of sampling (e.g., scraped or individuals were sampled), the source of the sample (e.g. boat, bumper, seawall), a description of the organisms removed from the debris, preservation method, current location of the sample, whether photographs were taken and their location, and various notes and comments.
Access to this data is temporarily RESTRICTED. Please contact the PI's for further information.

| 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.
