This scientific sampling event log was created using a very early implementation of the Rolling Deck to Repository (R2R) event log application (ELOG with cruise-specific custom configuration files). The log includes a record of all scientific sampling events from the cruise. OC467 was the first field test deployment of the R2R ELOG system.

Cruise track showing event locations
Post-cruise processing of the cruise event log was done by Cyndy Chandler (R2R and BCO-DMO). Event numbers were checked to ensure that all event numbers are unique. Text was modified in the event-type field to remove the colon character and simplify the entries. The R2R event number and original date and time in UTC have been removed from the data set.

| Description | Synoptic mapping of Alexandrium fundyense, hydrography, and velocity in the coastal current from Cape Cod to Georges Bank, Cape Cod to Bay of Fundy. OC467 is one of the GOMTOX project cruises to study the dynamics of Alexandrium fundyense distributions in the Gulf of Maine. GOMTOX is an observational and modeling study of nearshore and offshore shellfish toxicity, vertical toxin flux, and bloom dynamics in the Gulf of Maine, a complex shelf sea region.

Investigations of Alexandrium fundyense dynamics in the Gulf of Maine
Project Summary
Harmful algal blooms, commonly called "red tides" or HABs, are a serious economic and public health problem throughout the world. In the U.S., the most serious HAB problem is paralytic shellfish poisoning (PSP) , a potentially fatal neurological disorder caused by human ingestion of shellfish that accumulate toxins as they feed on dinoflagellates of the genus Alexandrium. These organisms cause human illness and death due to PSP, repeated shellfish harvest quarantines, and the mortality of fish and marine mammals. This phenomenon, which affects thousands of miles of U.S. coastline and numerous fisheries resources, has expanded dramatically in the last two decades, especially in the Gulf of Maine. ECOHAB-GOM is a project that addresses several fundamental issues regarding Alexandrium blooms in the Gulf of Maine: 1) the source of the Alexandrium cells that appear in the fresh water plumes in the western Maine coastal current (WMCC); 2) Alexandrium cell distribution and dynamics in the eastern Maine coastal current (EMCC); and 3) linkages among blooms in the WMCC, the EMCC and on Georges Bank. Utilizing a combination of numerical modeling, hydrographic, chemical, and biological measurements, moored and drifting current measurements, and satellite imagery, we are working to characterize the structure, variability and autecology of the major Alexandrium habitats in the Gulf of Maine.
