Garlmer Personnel Biographies


Otero, Ernesto
Ph.D. Student, Microbiology, (Hodson)

GARLMER Research:
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.
Other Research Interests:
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.
