Overview of the Curriculum

The Semester in Environmental Science is a 15-week program offered each fall semester that is devoted to the study of ecological systems. It is open to students enrolled at colleges participating in the MBL Consortium in Environmental Science.

There is no better way to find out about ecosystems than to interact with the scientists actively carrying out research; there is no better way to find out about research than to actually do it. The SES program emphasizes learning by doing -- students spend over 20 hours each week in the lab and field investigating forests, ponds and estuaries on Cape Cod. Virtually all ecosystems have been impacted by human activity, and so this is also a curriculum about how human-caused changes in the environment are affecting the globe.

Core Courses

The core course lectures cover both aquatic and terrestrial ecosystems from the point of view of biogeochemistry and important ecological processes. In the field and laboratory we will start out in the first eight weeks of the core courses with an intensive study focused mainly on local ecosystems -- ponds and estuaries within the Waquoit Bay watershed adjacent to Vineyard Sound, West Falmouth Harbor on Buzzards Bay, and the town forest at the municipal sewage treatment plant. Parts of the forest are sprayed with effluent from the plant, and so provide us with a large scale "experimental" manipulation of inputs of nutrients and water to a terrestrial ecosystem.

These ecosystems provide us with superb natural classrooms in which to learn the basic principles and techniques of ecosystems science. Each of the field and lab exercises in the core courses build upon one another. We start by measuring the biomass of primary producers in both the forest and water, then spend weeks 2-3 estimating the rates of primary production. Weeks 4-6 are devoted to examining the fates of organic matter produced by plants and algae. During week 4, students study the trophic structure – abundance and distribution of secondary producers as well as primary producers – in Waquoit Bay and Johns Pond, collecting samples for later analysis of food web structure. During weeks 5-6 students examine the rates of mineralization and respiration in both soils and sediments providing a basic introduction to nutrient cycling and stoichiometry of ecosystems. During weeks 7-8, students make additional measurements of the flows of nutrients and water through ecosystems to construct nitrogen and water budgets for these ecosystems. An important aspect of these labs is their interconnectedness. Data and information collected during each lab will be needed to further develop an understanding of the ecosystems.

Electives

In addition to the Core Courses, SES students take one elective which meets twice a week. The elective is intended to deepen understanding in a specific sub-discipline of ecosystems science.

Projects

The structured laboratory experiences and techniques of the core courses and electives set the stage for the most rewarding part of the SES program, the projects. During the last five weeks of the course, students will be able to devote full time to a project of their choosing. While the structure of a project is very flexible, we do ask that student work in teams with collaborators that they select. An ideal model for an independent project would be, for example, a collaborative study of the effect of fire on an ecosystem that included independent but complimentary work on soil chemistry, trees, and microbes.

Distinguished Scientist Seminar Series

A number of distinguished scientists are invited to give lectures and meet with SES students each year. It is an opportunity for students to hear from some of the country's top practitioners and to find out about their research and current concerns. During the visit of each of these scientists, the SES students are able to question them closely about everything from basic science to environmental problems to the availability of graduate programs.

Science Writing Seminar

SES students all take part in a seminar that introduces the art of science writing. This is taught by our writer-in-residence and several professional science journalists with the goal of illustrating how the results of scientific investigations can be transmitted to the larger reading audience in ways that catch their interest and educate. Students will write a profile of one of the distinguished scientists based on an interview. With this and other programs at the Marine Biological Laboratory, we hope to begin training a new generation of writers conversant in science who can communicate about critical environmental issues with the public.


We want to make SES a rewarding and fun educational experience for you. Please don’t hesitate to contact us information or help.
