Course description              

Ocean colour analysis is a proven tool for determining the health of ocean using oceanic biological activity through optical means. Phytoplankton pigment, chlorophyll, are indicators of equilibrium of CO₂ concentration between atmosphere and ocean. The oceanic colour changes due to chlorophyll a provides the level of primary productivity whereas the colour change due to CDOM can be attributed to the level of pollution and higher particulate matter. The ability of optical sensors to map the spatial and temporal patterns of ocean colour over regional and global scales has provided important insights into the fundamental bio-optical properties and bio-physical processes occurring in the aquatic media. Chlorophyll, SST and PAR can be operationally scaled up to estimate primary production and estimate the fish stocks. This training focuses on the basics of marine optics, ocean colour remote sensing, and its applications such as mapping primary productivity, phytoplankton classes and algal blooms. 

Learning outcomes

By the end of the course the participants should be able to:

• explain what Ocean Colour Remote Sensing and Marine optics are, and describe Ocean colour- sensor characteristics, data, and uncertainties.

• Perform atmospheric correction of ocean colour observations.
• Describe primary production mechanisms and P-I experiments
• Perform phytoplankton classification using ocean colour data.
• Use the SeaDAS tool for processing ocean colour data (including the software and Plug-in tools for ocean data processing).
• Use different ocean colour algorithms.
• Generate and validate ocean colour remote sensing products.
• Understand ocean colour applications like PP, HABs etc.

Pre-course Activities or Assessment

The mandatory online phase of the course takes place between 28^th November – 9^th December 2022 and this will be followed by the onsite course. The shortlisted candidates are expected to go through all the online course material and finish reading the material and the assignments before participating in the onsite course. The grades of the assignments will be added to the final grades.

Candidates must also familiarize themselves with the following:

1. Basic terminal commands (bash) in Linux (ubuntu) based system.
2. NetCDF files data structure
3. Understanding Satellite data levels (L0, L1, L2, L3)
4. Understanding basic concepts of ocean optics

Learner assessment

Assignment and tests will be conducted during the course while undergoing training. Pre-course assignments will also be counted for final grade.

Pre-requisites:

5. For dual boot systems with Linux-Windows, Original Windows OS and active antivirus subscription required for INCOIS provided internet access.

Course duration and format

The online phase of the course (~ 10 hours asynchronous, individual work) takes place between 28^th November – 9^th December 2022 and this will be followed by the onsite course (30 hours presential) between 12 – 16^th December 2022. The shortlisted candidates must go through all the online course material and finish the assignments before participating the physical course. The mandatory online phase of the course consists of reading assignments, self-assessment exercises and software installation and preparation, while the onsite course consists of lectures and practical exercises. Participants should be able to develop a mini project by the end of the course.

Application Process

A limited number of seats (30) is available. Please complete the online application form available on this LINK. The deadline to submit the application is 8 October 2022 (23:59 CET: Central European Time). There are no tuition fees.

UNESCO is committed to promote equal access principles. Applications from minority or underrepresented groups are strongly encouraged.
