Location:	Latitude: , Longitude:
General location information:	Terrebonne Bay, Gulf of Mexico, Louisiana HAB Area code(s): US-17
Additional location information:	Cross-shelf research transect SSE of Terrebonne Bay, Louisiana. Transect begins at 29.0567 degrees North 90.5317 degrees West, and ends at 28.7583 degrees North 90.2345 degrees West.
Bloom event dates (yyyy/mm/dd):
Quarantine levels dates (yyyy/mm/dd):
Additional date-related information:	Species data below represent cell concentrations of HAB species from surface samples collected during routine sampling for the period January - December 2007 (sampling is monthly) and were not associated with a particular bloom event. Species are reported at 10^5 cells/liter, with the exception of Prorocentrum spp. and Dinophysis spp. which are reported at 10^3, and Alexandrium monilatum and Karenia spp. which are reported when they are detected at any concentration. Cell concentrations were averaged over the number of phytoplankton samples collected on any given date in hte transect to generate an average concentration for a single sample date. Concentration data from samples collected on day trips to service our meters at one station in the transect (C6C) are reported as is.
