Abstract. Laboratory exercises in an academic setting can often be predictable in terms of their procedure and results. They are often conducted in a setting that does not provide many of the variables and constraints a real life setting might provide. In this presentation, students will outline a continuous 24-hour lab exercise in which they monitor fourteen (14) chemical and physical parameters in the Gulf of Mexico. Parameters such as ORP, DO, nitrate, ammonia, iron, hardness, pH, salinity, conductivity, tide height, temperature, sulfide, phosphate and TDS are measured periodically by a group of students over a twenty-four hour period. Doing this exercise at a marine lab on the shores of the Gulf of Mexico allows students to gather in-depth knowledge and a feel for the environment they are studying, something that cannot be replicated in the classroom.
