2010 Calanus Life History Workshop

Monday, 22 March 2010


  1. Review present capabilities, model needs in terms of model development and data needs.
  2. Compile available demographic and vital rate data for two species of Calanus in the North Atlantic, C. finmarchicus and C. helgolandicus, throughout their range. Specific information we hope to compile about each data set is the coverage in terms of:
    1. temporal extent
    2. spatial extent
    3. developmental stage determination
    4. methodologies used
    5. ancillary data collected simultaneously
  3. Identify willing participants in data analysis for large scale comparative studies of Calanus across the whole Atlantic, encompassing the entire range of both species, and using the compiled data sets.
  4. Make a tentative timetable for completion of analysis related to the compiled data sets.
  5. Make a tentative plan and timetable for data access.

Plenary Discussion Questions:

  1. Data needs for models: are we measuring what is needed?
  2. Parameterization needs and proxies for food availability
  3. Coupling biologically rich models to Eulerian circulation models
  4. Predicting future distribution shifts and cross shelf supply to coastal areas
