Ocean Colour Remote Sensing - Data, Processing and Analysis [blended course]

14 - 25

Résumé

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.
  • Understand Ocean colour Algorithms, Chlorophyll, shallow water remote sensing, algal blooms
  • 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.
