Focuses on the ocean's role in the global biogeochemical cycling of selected elements and the impact of humans on the transport of these elements. Among the topics covered are the chemical composition of seawater from the perspectives of elemental speciation and the impact of solutes on water's physical behavior; biogeochemical phenomena which control accumulation and preservation of marine sediments; marine chemistry of radioactive and stable isotopes; seawater pollution. Contains many examples as well as steady-state models to aid readers in understanding this relatively young, growing and complex science.

Dr. Susan M. Libes is professor of marine science and chemistry at Coastal Carolina University, Conway, SC.  She earned a B.A. in chemistry from Douglass College, Rutgers University and a Ph.D. in chemical oceanography from the WHOI/MIT Joint Program in Oceanography and Ocean Engineering.  She served as the chair of the marine science department chair from 1993 to 2000.   Since 1992, she has been the Program Director of CCU’s Environmental Quality Laboratory.  In 2003, she became the founding director of the Waccamaw Watershed Academy.  Her current research activities focus on eutrophication and hypoxia in fresh and marine waters.
