CAFÉ Workshop Update
  • CAFÉ 2006, Nov. 7-8, Portland, ME
    • 24 participants from 3 countries


3
CAFÉ Workshop Update
    • Day 1: Arctic Climate Influences on NW Atlantic
      • Early & late 1990s FW anomalies
      • Good evidence early anomaly came from Arctic, likely through Canadian Archipelago
      • Late anomaly is better described in GoM/MAB, but origins are less clear
      • Contrasted GoM plankton changes with Canadian Shelf
        • Similar, but more winter-spring than fall-winter
    • Day 2: Top-down vs. Bottom-up drivers
      • Some interesting top-down linkages, but trophic cascade not supported by data
      • Cod in Newfoundland are food limited

First Impressions
  • In general, strong similarities to GoM
    • Inverse relationship between Calanus and Ctyp
    • 80’s vs. ‘90s
  • But
    • Different species have strongest response (Ctyp vs. Metridia)
    • No reversal in 2001
  • Some things to look at
    • Calanus, Calanus, Calanus
9
Summer Plans
  • Ocean Sciences session on “Arctic influences on Atlantic ecosystems”
  • Continue CPR workup
    • Hope to expand analysis to entire shelf
  • 1D modeling of freshwater anomalies and phytoplankton blooms
  • Plan for CAFÉ 2007
10
Right Whale, Wrong Time?
  • Only 350 N. Atlantic right whales
  • Recovery limited by mortality
    • Ship strikes
    • Fishing gear
  • All management options depend on knowing where whales are
11
Cetacean Informatics
12
RWPS 1.0
  • Climatological circulation fields, initial conditions, boundary conditions
    • No interannual variability
  • SST and Chlorophyll from 1998-2004
    • Only source of interannual variability

Implications for GLOBEC
  • GLOBEC models are useful!
  • Calanus abundance reflects conditions over previous months
    • Even a little data is valuable
