General Chemistry II
Designed to provide a foundation for more advanced
courses in chemistry. The topics covered include the
atomic theory, the laws and theories concerning the
physical and chemical behavior of gases, liquids, solids,
and solutions. The properties of some of the more familiar
elements and their compounds are discussed. Particular
attention is given to equilibrium in solutions and to
the qualitative reactions of the common cations and
anions.

Special topics: Trace Metals in the
Aquatic Environment
This course is divided into three modules. Module 1
will start with a brief review of theory of chemical
thermodynamic (equilibrium) approaches to studying aquatic
systems as well as homogeneous and heterogenous reaction
kinetics. The biogeochemistry of metals in the atmosphere,
including photochemistry, will be covered as well as
trace metal cycling in aquatic systems (marine/estuarine
systems/sediments and in lakes/rivers and groundwater)
and their chemical speciation. The second module will
cover the practical application of thermodynamic modeling
to the acid-base and carbonate system as well as to
redox reactions and interactions with solids. The modeling
of metal binding to surfaces and to organic matter will
also be discussed. Pertinent literature on modeling
studies will be covered. The third module will discuss
the environmental interactions between metals and biota,
including bacterial methylation/demethylation and redox
transformation of metals; metal uptake into phytoplankton
and other microbes; the role of metals as essential
nutrients to phytoplankton; the uptake of metals into
invertebrates and vertebrates, as well as approaches
to modeling such interactions

Measurement and Analysis in Coastal
Ecosystems
This course provides an introduction for upper level
undergraduate students in the analytical methods and
approaches to examining the biogeochemistry and ecology
of coastal ecosystems. The methods covered included:
Winkler oxygen titrations and other oxygen measurement
techniques; measurement of productivity using the light/dark
bottle technique; estimation of gas exchange across
surfaces; nutrient methods (phosphate, nitrogen species);
CHN (carbon and nitrogen) analysis; measurement of methane
by gas chromatography; chlorophyll measurement and measurement
of plant pigments by HPLC; PCR and other methods for
quantifying bacterial abundance; remote sensing applications;
measurements of mercury and other metals in sediment
cores using ICP-MS and a solid phase mercury analyzer;
techniques for dating sediment cores; STELLA modeling
of an coastal ecosystem. In addition to exposure to
the methods, students were also introduced to the complimentary
ecological, chemical and physical aspects through field
trips and through course instruction.
