Topics for Research

 

 

Nutrient inputs, cycling, and microalgal taxonomy.

 Dr William Burnett (Florida State University) and student: trace groundwater discharge using Ra and Rn radioisotopes

Dr Bezhad Mortazavi (University of Alabama) and student: measure benthic fluxes

Dr Hugh MacIntyre (Dauphin Island Sea Lab), Justin Liefer & Lucie Novoveska
(University of South Alabama), LLPS: continued monitoring of nutrients
and microalgal community composition. 

 

  

  

 

 

 

 

 

 

 

 

Nutrient Source

Dr Ruth Carmichael (Dauphin Island Sea Lab): measure 15N/14N (d15N) signatures of particulate and dissolved nitrogen to assess likelihood of fertilizer vs other origin.

 

 

 

 

 

 

 

 

 

 

 

 

 

   

 

 

 

Pseudo-nitzschia spp toxicity

Justin Liefer and Dr Alison Roberston (FDA Gulf Seafood Lab): conduct bio-assays for triggers of toxicity and exposure experiments for transport of toxin into food-chain. 

 

 

 

    

 

 

 

 

 

 

 

 

 

  

 

 

 

 

 

  

Microbial Source Tracking

Dr Alice Ortmann (University of South Alabama): assay species-specific ribosomal RNA sequences to determine most probable origin of fecal coliforms.

 

 

 

 

 

 

 

 

 

  

   

 

Circulation and flushing.

Dr Kyeong Park (University of South Alabama): mass balance box model of lagoon to estimate residence time and conduct scenario runs

Dr Hugh MacIntyre & Justin Liefer (DISL): couple algal growth model to circulation/flushing model.
