IOCCG Summer Lecture Series 2012

2 – 14 July 2012 - Villefranche-sur-Mer

The International Ocean Colour Coordinating Group (IOCCG) organized the first IOCCG Summer Lecture Series dedicated to high level training in the fundamentals of ocean optics, bio‐optics and ocean colour remote sensing. This was a 2‐week intensive course that took place from July 2nd – 14th at the Laboratoire d'Océanographie de Villefranche (LOV), Villefranche‐sur‐mer, France. A total of 13 renowned lecturers were invited to teach at the course and 17 students from 13 different countries took part in the course. More than 100 students had applied to participate in the course and the 17 remaining applicants were primarily chosen with respect to their motivation and on the basis of their academic background. The majority of them were PhD students and post‐Docs, and some were starting their careers as young researchers. The participants came from a broad range of backgrounds, but all were familiar with at least some domains of ocean colour science and had a solid understanding of ocean colour remote sensing.

  1. What are harmful algal blooms (HABs)?
    • Contrast of HABs to functional groups
    • What must be known to detect HABs
    • Environment
    • Simple physiology and ecology
    • Ecological conditions
    • “Operational” vs research considerations
    • Work exercise: A strategy to respond to reports of a HAB
  2. Methods
    • Chlorophyll
    • Change detection
    • Analytical algorithms
    • Spectral shape (MCI, FLH, CI)
    • Other algorithms (brightness, empirical, etc.)
    • Ancillary data (SST, winds)
    • Ensemble methods
    • Work exercise: Case Study (to be provided)
  3. Using satellite
    • Limitations defined by objective, method, species, environment
    • Satellite strengths and weakness
    • Algorithm failures
    • Atmospheric correction challenges
    • Work exercise: identify best method for a case study (to be provided)
  4. Validation
    • Quantitative data vs qualitative data
    • False positives and false negatives
    • Field observations (ocean color, cells, toxins, impacts)
    • Work exercise: sampling strategy
  5. Applications
    • Advisories
    • Forecasts
    • “Event response” (dead marine mammals, fish kills, bird kills, sickness)
    • Discussion of case studies
