This report summarizes the data generated from sediment porewater toxicity tests and dissolved organic carbon analyses of sediment pore water by the Marine Ecotoxicology Research Station (MERS) in support of a sediment quality triad (Triad) assessment at the Calcasieu estuary in Louisiana. The Triad approach is used to quantify risk associated with contaminated sediments by integrating information on sediment toxicity, sediment chemistry, and benthic community structure in a weight-of-evidence approach. Data summaries presented in the current report include: (1) porewater fertilization and embryological development tests with the sea urchin, Arbacia punctulata, (2) porewater toxicity tests with redfish, Sciaenops ocellatus, embryos, (3) porewater zoospore germination test with the macroalga, Ulva fasciata, and (4) dissolved organic carbon (DOC) analysis of porewater samples.
