Location: Latitude: , Longitude:
General location information: Cross-shelf research transect W of the mouth,
HAB Area code(s): US-17
Additional location information: Transect begins at 29.2733N 91.6167W and ends at 28.6917N 91.6167W
Bloom event dates (yyyy/mm/dd):
Quarantine levels dates (yyyy/mm/dd):
Additional date-related information: The data below represent cell concentrations of HAB species at or above 10^5 cells/liter (with the exception of Prorocentrum species which were reported at or above 10^3) encountered in routine sampling in 2004, and were not associated with a particular bloom event. Cell concentrations were averaged over the four stations in the transect to generate an average concentration for a single sample date.
