Primary Question: What is the efficacy of satellite Ocean Color and Sea Surface Temperature (SST) data in monitoring phytoplankton populations in the turbid, Case II waters of the Northern Gulf?
Goal: Evaluate the use of MODIS and SeaWiFS Ocean Color data and MODIS SST data for assessing phytoplankton populations in the Northern Gulf of Mexico.
Tasks:
1. Determine taxonomic composition of phytoplankton communities
2. Determine primary environmental factors controlling phytoplankton populations
3. Acquire MODIS and SeaWiFS data corresponding with in situ sampling dates
4. Apply Ocean Color algorithms5. Determine relationships of Ocean Color and SST data
products with phytoplankton population data6. Compare MODIS vs. SeaWiFS utility7. Derive conclusions regarding the efficacy of Ocean Color and
SST data as indicators of phytoplankton composition in Case II waters
8. Prepare and submit final report to NASA9. Publish results in the peer-reviewed literature
HAB species detected in MS waters
• Pseudo-nitzschia spp. (Amnesic SP)
• Karenia brevis (Neurotoxic SP)
• Karenia mikimotoi (NSP)
• Gymnodinium sanguineum (Paralytic SP)
• Dinophysis caudata (Diarrhetic SP)
