1.Coastal Waters Quality

In 2006 Dr. Briceño became Co-Principal Investigator for the SERC Water Quality Monitoring Network (, whose function is to address regional water quality concerns that exist outside the boundaries of individual political entities. Funding for the Network has come from many different sources with individual programs being added as funding became available. Field sampling occurs over different time periods due to the nature of the funding. Biscayne Bay, Florida Bay & Whitewater Bay, Ten Thousand Islands, and Marco-Pine Island Sound are sampled monthly, while the Florida Keys National Marine Sanctuary and the Southwest Florida Shelf are sampled quarterly. The data summary maps are produced on a quarterly basis by integrating the individual projects into one data file for that month sampled.

     The advantages of having this Network operated from the same facility include site continuity, consistency in analytic methodology, and ease of data integration. The product is a quasi-synoptic "big picture" as to what is happening in the South Florida coastal waters.


Since 1997, while in EIG Litos C.A, Dr. Briceño was responsible for the Geochemical and Chemostratigraphic projects for hydrocarbon exploration. Among the studies he carried on the characterization of twelve Cretaceous-Tertiary stratigraphic sections in Southwestern Venezuelan Andes, Tachira State.

Multivariate statistical analysis of inorganic (Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Nb, Mo, Ag, Cd, La, Ce, Hf, Ta, Th, U, Na2O, MgO, Al2O3, SiO2, P2O5, K2O, CaO, TiO2, Cr2O3, MnO, Fe2O3 and LOI) and organic (TOC, pyrolysis Rock-Eval, HI, OI) and development on new techniques (Chemical Accumulation Rate Diagrams, CARD) to trace changes in sedimentary environments of deposition, tectonic regime and source rock changes, for correlation and modeling purposes.
