Deep Sea Biology

Most of the ocean is deep, dark, and cold – conditions that at first glance appear terribly inhospitable. And yet the past century and a half of deep-ocean exploration has revealed an astonishing abundance and diversity of life, with forms and functions that, though seemingly alien, reflect exquisite adaptation to the unique challenges of surviving in such an environment. Our expanding knowledge about the deep ocean is only possible with the boundary-pushing technologies and instruments developed to delve deeper, see further, and collect more from the most remote depths. As we have learned more about the ecosystems in the deep ocean, it has also become clear that human activities are not so removed from them as we once believed. Discussions about deep ocean biology now include debates about our obligation to protect and conserve it.

In this course, we will take a tour of the variety of life that exists in the deep ocean, learn about how we observe and study it, and discuss the ways that humans interact with and affect it. Our guiding questions for the course are:

What kinds of life exist in different deep ocean ecosystems? How are deep sea organisms adapted to life in an environment of extremes? What technologies are used to study life in the deep ocean and what are their capabilities and constraints? What do we owe to life in the deep ocean in terms of conservation? What do we owe to human society in terms of deep-ocean exploration, discovery, and resource use?

We meet twice a week in class and have one afternoon lab period. Classes are a combination of lecture, discussion and activities, and labs focus on one or two elements of deep-sea biology for deeper investigation as a group. This course is open to anyone but is particularly suited for students interested in marine studies, ecology, evolutionary biology, and/or environmental ethics. Students will be assessed based on short research assignments throughout the course and a term project.
