Studies of the utilization of naturally
occuring substrates by the bacterial communities in Altamaha and
Satilla river estuaries. My studies are based on stable isotope
analyses of bacterial DNA and particulate and dissolved organic
constituents of estuarine water. Analyses conducted are those
of chlorophyll, dissolved organic carbon, total organic carbon
and humic matter concentration in relation to their stable
isotope signatures and characterization of terrestrially derived
material based on profiles of lignin oxidation products and
their delta 13C.
Sulfate reduction in tropical coastal and reef
environments; remote sensing of suspended particulate matter and
chlorophyllous pigments in coastal tropical waters; trace element composition
of mangrove dominated areas; marine pollution monitoring.
