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

- 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

- 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

|
- 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

|
- Only 350 N. Atlantic right whales
- Recovery limited by mortality
- Ship strikes
- Fishing gear
- All management options depend on knowing where whales are

|
- Climatological circulation fields, initial conditions, boundary
conditions
- No interannual variability
- SST and Chlorophyll from 1998-2004
- Only source of interannual variability

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