Narrative
The meeting began with Cabell Davis welcoming the group,
presenting meeting logistics and goals, and reviewing/summarizing
program interconnections.
Welcome, logistics and program overview.
Davis reviewed the meeting
agenda. The meeting began at 09:00 with introductory comments by
Davis followed by individual project talks from 09:15-12:30, including
a coffee break from 10:30-11:00. Following lunch from 12:30-13:30,
free time was allocated from 13:30-15:00 to allow for intra- and
inter-project interactions and discussions. From 15:00-17:00, the
PIs discussed the nature and potential content of a US GLOBEC Northwest
Atlantic (NWA) synthesis volume. The meeting adjourned at 17:00.
In his overview, Davis presented the meeting goals and briefly
reviewed the overall US GLOBEC NWA program goal and major findings of
the field program. He reviewed the interconnections between the
different Phase 4B projects. He gave a quick synopsis of the
program goal: "To understand the processes controlling recruitment
of cod and haddock and their dominant prey species", and showed the
stock-recruitment and biomass-at-age data for Georges Bank haddock.
He pointed out that our ultimate objective is to provide insights
into the causes of good and bad year classes. He then reviewed the
US GLOBEC broadscale station results, including the increase in copepod
abundance from 1995-1999, the low-salinity anomaly and its
association with earlier spring phytoplankton blooms, and the
enhanced growth and survival of cod and haddock larvae. The source
of the low-salinity water from the Labrador Sea and possible Arctic
origin was reviewed.
Individual Project Talks
Following this introduction and program overview, the individual
project talks began. Six talks from four projects were presented
during the morning session. (The Greene et al. project was not
represented at the meeting, but Pershing emailed a project briefing
to Davis prior to the meeting.)
Davis presented an introduction of the NPZD-copepod species
FVCOM-modeling project,
Modeling 3D Copepod Distributions on Georges Bank During 1995 and
1999.
Following this overview, Rubao Ji presented the latest results of
the copepod modeling work,
An Update on Bio-Physical Coupled Modeling Study for U.S. GLOBEC Georges
Bank Phase 4B.
Bob Beardsley presented the latest FVCOM
physical modeling results via teleconference,
Progress Report of the Gulf of maine
Integrated Model System.
Dave Townsend
presented results on nutrient analysis for the Gulf of Maine region,
Nutrient Dynamics in the
Georges Bank -- Gulf of maine Region.
Trond Kristiansen then presented larval fish modeling results for
the Werner et al. project,
Factors Determining Growth and Survival in Early Live Stages of
North Atlantic Cod: A Comparitive Study Between the NW Atlantic
and Norwegian Sea Echosystems
.
Catherine Johnson reviewed progress in the
Runge et al. Calanus diapause study,
Characteristics of Calanus finmarchicus Dormancy Patterns in the Northwest
Atlantic
.
Avijit Gangopadhyay
summarized progress on their basin-scale Calanus study,
Update on Basin-Scale Modeling and IBM
.
Copies of the PowerPoint presentations are available via the abstract pages
of this report.
Meeting Summary
The Phase 4B meeting successfully accomplished its goals. Each
group gave clear presentations of their project goals and progress.
The interactions between groups were useful including transfer of
modeling techniques and tools between the Davis et al. copepod model
and the Runge et al. diapause model. Linkages were established
between the modeling work in the Werner, Davis, and Gangopadhyay
projects. The results from these studies will contribute to a broad
understanding of the effects of local and remote forcing on
ecosystem and population dynamics of the target species. While the
focus of the phase 4B research is primarily on scientific questions,
this research is being done with consideration for transitioning
results and models to operational tools useful to management. The
discussion of the synthesis volume also was useful and it was
decided that rather than prepare a book, which will have small
readership, a special volume of a journal such as Progress in
Oceanography with electronic presence would be the best venue.
Electronic format has wide web presence and allows presentation of
animations and a better forum for outreach interactions.
