Syllabus

Welcome to the world of ‘the unseen majority’ of the ocean! A drop of seawater contains billions of cells from the three domains of life: bacteria, archaea, and eukarya, as well as viruses. This is the marine microbiome. Come meet those microbes, and you will learn that they are our essential allies in the fight against climate change.

The lectures will cover the key microbial groups in the ocean, lessons learned from their fossil records, current status in the oceans, and forecasts regarding this acclimation to the future ocean conditions. We will discuss the metabolic process occurring inside those cells, or between interacting microbes, and how they impact over vast scales of space and time.

There are no prerequisites for the course. This is a basic level course in marine microbiology- it can benefit life science and chemistry students, MSc and PhD level, providing them with a strong background in marine microbiology, which could also assist them in many other fields of study.

The lectures:

1) Marine microbes and the carbon cycle (A guest lecture by Dr. Yinon Bar-On)

2) Cyanobacteria 

3) Diatoms

4) Coccolithophores

5) Dinoflagellates

6) Heterotrophic bacteria

7) Microzooplankton

8) Marine viruses

9) Microbes at the air-sea interface (A guest lecture by Dr. Michel Flores)

10-13) Journal clubs

Learning Outcomes

During the lectures and the student’s seminars, we will explore the following questions:

  • Who are the key players in the ocean microbiome and how they interact?
  • How do small microbes impact biogeochemical cycles on an oceanic scale?
  • How do microbes sequester, transform and shuttle carbon into the ocean interior?
  • How microbes modulate food web dynamics via predation and pathogenicity, and recycle nutrients such as nitrogen, phosphorus and sulfur?
  • How do microalgae produce climatic gases which are being exchanged between seawater and the atmosphere?
  • What are the anthropogenic threats posed to marine microbes? Can we protect them?
