What will be the legacy of GLOBEC NWA?

"The challenge to all prospective investigators is to demonstrate convincingly that their work leads to a new level of understanding of the links between the atmosphere, ocean physics, and population dynamics of marine organisms, in the context of climate change" (GLOBEC Report #6, p 6)

GLOBEC NWA Hypotheses

1)In situ growth rather than lateral exchange is the dominant process controlling the abundance of animals on the Bank;
2)Seasonal density stratification over the S flank causes prey aggregation in the pycnocline and thus increased survival of predator populations;
3)Temporal changes in mixing and stratification may control the abundance and spp. composition of phytoplankton which in turn may result in different rates of growth and production of herbivorous copepods in well-mixed, frontal, and stratified regions of the Bank;
4)The occurrence of large, episodic exchanges of water and organisms on/off the Bank contributes to variability in popn abundances;
5)Seasonal density stratification and the processes of turbulent mixing influence predator-prey encounter rates and thus the growth and survival of individual organisms;
6) Predation rather than starvation is the dominant source of mortality of fish larvae; predation rather than advective loss is the dominant source of mortality of copepods.

Vastly increase our understanding

1)What do you know now about Georges Bank that you didn't know 10 years ago? If you were to re-write the NWA Implementation Plan (GLOBEC Report #6) pp 6-24, what would be different?
Georges Bank book?
"State of Georges Bank" report?

2) How will changing climate/NAO affect GB processes, structure, and function?

The secondary production of ocean ecosystems in the context of a changing global climate.

Important Events

98/99 recruitment
98 copepods?
Scotian Shelf crossovers
Hydrographic interannual variability
NAO shifts

What are the dominant/controlling processes on Georges Bank?

What larger (basin-scale) processes are at work to determine popn dyn and secondary production on GB?

How would a climate signal propagate through the GB ecosystem? "links between the atmosphere, ocean physics, and population dynamics of marine organisms, in the context of climate change

Predictive capability

What can you predict? On what time/space scales? With what uncertainty? Who will use these predictions? How will these predictions be used? Management uses

What GLOBEC results are being used now in fisheries management? How has GLOBEC improved the management of living marine resources?

Where, when and how often should future measurements be taken to capture important features of Georges Bank/GoMe? (tie-in with Ocean Observations) Technology development What GLOBEC technology is routinely used in NOAA operations now?

Presentation Materials

In early GLOBEC years, Zack and Peter pounded the corridors of Congress drumming up support for the program

In past COP crises, it was argued that some action/budget cut/reorganization would be devastating to GLOBEC

Now, it's time to show how support in Congress and saving COP funding has led to tremendous success in GLOBEC
