Elements cycles in the ocean : Forcings, disturbances, methods

EMBC+ MODULE 1: Understanding the structure and function of Marine Biodiversity
semester: 
3
ects: 
6

The course is organized under 3 main parts, each one composed of 2-3 boxes:
I. Forcings: What are the internal and external forcings of element biogeochemical cycles in the ocean?

  1. The microbial loop
  2. Land – Ocean interface and continental margins
  3. Bio - physical mesoscale and submesoscale coupling

II. Disrupted cycles: What are the main changes occurring?

  1. Desoxygenation & Eutrophication
  2. Acidification

III. Paleocycles and managed cycles: How were the biogeochemical cycles in the past and can we manage them in the future?

  1. Paleocycles
  2. Geo-engineering

Overarching these 3 parts and boxes, there will be a series of lab-works illustrating some of the advanced methodologies to study these themes.

In addition, there will be a 1-day workshop with scientists involved in IPCC to explain how biogeochemical cycles are integrated in global climate models.
