Methods of sampling and analyzing physical, chemical, and biological properties of the air, water, and earth. An emphasis will be placed on research question formulation and sampling design. By the end of the course, students will be able to independently develop a field study, collect and analyze field data, and present their findings in a written report. We will focus on our local estuarine environment, although the general research process covered can be applied to any system. Prerequisites: Any two of the following: MRNE 110, BIOL 105, BIOL 106, CHEM 106, ENST 250.
