| Dave: Interdecadal changes in cod/haddock growth | |

| Whales |
| 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 | ||
