About the Course
This course will help you learn about life in the ocean, how ocean ecosystems function, how scientists study the ocean, and the challenges we face in sustaining healthy oceans for the future. These topics will be explored using case studies that focus on charismatic marine megafauna species the most compelling creatures in the ocean that capture our attention and inspire us to learn more.
The course starts with an examination of the physical dimensions of the worlds ocean and how we describe ocean zones based on the ecosystems found within them. Once these basics are covered, we will work through the evolution of life in the oceans and explore how marine animals have adapted to the challenges of a cold, dark and deep ocean. Throughout the class we will highlight how scientists study the oceans and the animals that live in them, providing glimpses of new technologies that boost our understanding of marine ecology. The course will also cover some of the challenges the oceans face due to human activities - exploring issues such as bycatch and climate change - and how they are affecting ocean species and systems.
PLOS ONEThroughout the course we will connect with real marine science through the use of open access scientific articles published in the journal PLOS ONE. This means you will have to learn how to read scientific papers and extract the important bits of information from them. The articles youll be reading are all part of a new PLOS Collection focused on using open access research to teach marine science and conservation. You will also get to look at real datasets produced by scientists studying marine creatures and visualize them in freely available programs such as Google Earth.
Course Syllabus
Week 1. Getting Started
Welcome to Marine Megafauna - some basic introductions are in order!
Cracking the code: How to read a PLOS ONE journal article. Students will learn how to approach reading a PLOS ONE article.
Ocean Basics. Students will learn the basics about the ocean(s).
Origins of Marine Megafauna. Students will learn the evolutionary origins of the major groups of megafauna that live in the sea.
Week 2. Introductions to Marine Megafauna - Diversity and Taxonomy I
Introduction to Sea Turtles. Students will learn basics about sea turtle diversity, biology and ecology.
Introduction to Seabirds. Students will learn basics about seabird diversity and ecology with a focus on colonial living.
Introduction to Penguins. Students will learn basics about penguin biology and ecology.
Week 3. Introductions to Marine Megafauna - Diversity and Taxonomy II
Introduction to Marine Mammals. Students will learn basics about diversity of marine mammals.
Introduction to Large Fishes. Students will learn basics about diversity, biology and ecology of large fishes.
Introduction to Marine Mega-Invertebrates. Students will learn basics about mega-invertebrate diversity and ecology.
Oceanography and Biogeography of Marine Megafauna. Students will learn about the links between oceanographic features and marine productivity with focus on coastal upwelling.
Week 4. Adaptations to life in the ocean I
Ecophysiology of large marine animals. Students will learn about physiological challenges posed by living in the ocean: thermoregulation, pressure, osmoregualtion and more.
Functional morphology and diving physiology. Students will learn about adaptations that allow animals to move efficiently and dive.
Movements, migrations, and behaviors. Students learn about movements of animals in the ocean - vertical migrations, latitudinal trips and ontogentic descents.
Week 5. Adaptations to life in the ocean II
Foraging and Feeding in the sea. Students learn about how animals forage and feed in the ocean.
Bioenergetics and the challenges of ocean living. Students learn about energy flow in individuals and populations.
Trophic ecology/foraging theory. Students learn about trophic structures and the complexity of marine food webs.
Reproduction and life history strategies. An overview of life history and reproductive strategies of ocean animals.
Week 6. Oceanography and Deep Sea Biology - Robots and Subs
Oceanography techniques. How we study ocean currents and water properties.
Deep sea biology and ecology. An introduction to the ecology of deep sea systems.
Chemosynthetic life in the ocean. How life exists without light.
ROVs, AUVs, Ocean Gliders and manned submarines. An introduction of the use of robots and subs to study marine systems.
Week 7. Marine Conservation I
What is marine conservation biology? A description of conservation and how conservation conflicts proceed.
The role of individuals and science in conservation. An overview of how individuals shaped the terrestrial conservation movement and how science fits into the overall process of sustaining marine resources.
Marine Acoustic Ecology. Introduces students to ocean acoustics and why sound is so important to animals in the sea.
Anthropogenic noise. Provide an overview of the most pressing issues in marine bioacoustics: seismic, shipping, sonar.
Week 8. Marine Conservation II
Seals, Fisheries and coastal conflicts. Provides an overview of the classic marine predator problem in marine systems - the recovery of pinnipeds from persecution/exploitation and how that may affect coastal communities.
Bycatch. Students learn about bycatch and how it affects marine systems.
Whales and whaling conflicts. Students learn about historical commercial whaling and the current conflicts surrounding it.
Climate change. Students learn about the basics of climate change and how it affects marine species.
Recommended Background
Some familiarity with basic biological and ecological concepts as they relate to the ocean.
Suggested Readings
All readings for the course are published in the open access journal PLOS ONE. In the course of reading those articles, you will no doubt be intrigued by other papers cited within them. Find your marine passion, and see how far down the rabbit hole goes!
Course Format
The class will consist of a series of lecture videos that are between 8 and 20 minutes in length. These videos contain several integrated, ungraded quiz questions per video. Students are required to read and understand several research article per week, and the complexities of these articles will be discussed in online discussion fora. There will also be standalone homework sets, including working with datasets derived from real scientific research.
FAQ
Will I get a Statement of Accomplishment after completing this class?
Yes. Students who successfully complete the class will receive a Statement of Accomplishment signed by the instructor.
What resources will I need for this class?
Students will need to access several free programs (e.g., Google Earth) to visualize data provided throughout the course.
What is the coolest thing I'll learn if I take this class?
You will learn how penguins keep warm, how blue whales eat and how everything in the ocean - from the biggest creature to the smallest - is connected.
