The PICES Special Publication, "Marine Ecosystems of the North Pacific", concluded that "during the past five years profound changes have occurred in the North Pacific climate system, in the composition, abundance and distribution of its living marine resources, and in the human societies that depend on the North Pacific Ocean and its resources". This symposium will build on studies of climate variability and other anthropogenic impacts in the North Pacific and its marginal seas, the latest North Pacific climate projections (whose results have been summarized in the Fourth Assessment Report of the Inter-governmental Panel for Climate Change), future scenarios for direct human forcing by population growth and fishing, and the combined impacts that these changes have already had, and can be expected to have, on North Pacific ecosystems. The symposium will address issues such as: 1) trends versus variability; 2) synergisms between climate and direct human forcing; 3) ecosystem indicators and their applicability in the future; 4) impacts arising from regional changes (e.g., less ice-cover in the Bering Sea and Sea of Okhotsk, aquatic bioinvasions); 5) the effects of terrestrial climate change (e.g., river discharge); 6) how projected global change and anthropogenic impacts may alter sustainability of the North Pacific; and 7) what the key messages should be for policy makers regarding sustainability of the North Pacific. Talks describing links with climate change in the Arctic and the International Polar Year Projects are also welcome.

This session will be the first effort by the PICES Section on Carbon and Climate (CC-S) to synthesize the current understanding on inter-relationship between the carbon cycle and climate in the Pacific. Emphasis will be placed on decadal change in carbon cycling, e.g., anthropogenic carbon, air-sea exchange of CO2, the biological pump, impacts of increasing levels of carbon dioxide on carbonate chemistry and marine biota, and possible feedbacks to atmospheric greenhouse gases. We expect that the session will enable us to update our understanding of the relationships between the carbon cycle, marine biota, and climate in the Pacific, and to identify gaps in our knowledge for future research in areas of importance for the PICES Section on Carbon and Climate.

Ecosystem-based management is becoming a focus for many fisheries and their management agencies worldwide. Much of the success of this initiative will require improvements in understanding the interactions and linkages among species at both the lower trophic level (LTL) and higher trophic level (HTL) within regional ecosystems. The recent success of modeling tools such as NEMURO.FISH in linking LTL forcing to the forecasting of fish growth for a number of pelagic forage species is encouraging. Ecosystem-based management will require the extension of this and/or similar approaches to multispecies systems. A variety of modeling tools is already in wide use to address this issue, including Ecopath/Ecosim, NEMURO, various IBM models, and others. This session will focus on contrasting different approaches to multispecies modeling and evaluating their performance as a vehicle for assessing and forecasting the effects of climate change on ecosystem function. We encourage presentations that will highlight critical ecosystem interactions relevant for fishery management, and discuss how knowledge of these interactions will move us closer to ecosystem based fishery management.

Ecosystem approach to fisheries: Improvements on traditional management for declining and depleted stocks

An ecosystem approach to fisheries (EAF), which recognizes the complexity of ecosystems and the interconnections between its component parts, has been recently advocated by many fisheries management bodies. In PICES countries, some fisheries resources are in high abundance and healthy, but others are decreasing or already depleted. Most causes of stock declines can be ascribed to climate changes and overfishing. Stocks in declining or depleted conditions require prompt, appropriate management actions, perhaps including ecosystem approaches. This session invites papers that examine: (1) major factors responsible for the status of fish stocks, particularly those that are decreasing or depleted; (2) limits to traditional fishery management measures to address causes of stock declines; (3) new perspectives on fishery management that promote sustainable fishery management from an ecosystem perspective; and (4) case studies of rebuilding plans for depleted stocks - their successes and failures. Manuscripts contributed to this session will be considered for publication in the journal Fisheries Research following peer-review. Submission deadline of manuscripts is November 30, 2007.

Ecosystem models are often employed to evaluate the effects of fishing and to distinguish natural variability from human impacts. These models typically operate at large spatial and temporal scales, which are appropriate for their goals and objectives. However, these models would benefit from better information on local-scale processes as there are likely to be bottlenecks at short time scales and small spatial scales that are critical to understanding recruitment variability. Similarly, there may be critical foraging interactions that happen at local scales, particularly for central place foragers such as marine mammals and seabirds. Small-scale effects of fishing such as "localized depletion" may have ecosystem-level consequences. More information on local-scale survival, foraging, movement, reproduction and pelagic habitat selection would allow food-web and population dynamics modelers to make better scenarios of the effects of natural variability and/or fishing on ecosystems. Papers are solicited on the following topics: (1) current ecosystem models and the assumptions that require further research; (2) techniques for assessing climate impacts on predator-prey interactions at top trophic levels; (3) techniques for assessing local-scale dynamics of survival, foraging, movement, reproduction and pelagic habitat selection; and (4) techniques for assessing prey field response to fishing.

There is increasing recognition that some harmful algal blooms (HABs) affecting coastal waters may not have local origins but are advected from offshore waters. This session will highlight recent advances in studying the processes involved in near-shore versus off-shore development and transport of harmful algal blooms in the coastal waters of the PICES region. Of particular interest are field studies where the relative importance of local versus remote development of HABs has been assessed. The session convenors are soliciting papers describing known off-shore and near-shore initiation sites, seedbeds, and the physical factors that facilitate transport of HABs to coastal sites where they may impact fisheries.

Invited speaker:
Alex David Rogers (Institute of Zoology, Zoological Society of London, UK)

Some of the fauna that are most vulnerable to physical disturbances are the long-lived, slow growing and physically fragile species (corals and sponges) that provide biogenic habitat in deep water. It is increasingly recognized world-wide that deepwater biogenic habitat has not been conserved in the past, with the result that the conservation of such habitat has become a high priority in many jurisdictions. At least in the eastern Pacific, large areas have been established to exclude bottom trawling to protect deep-water corals and sponges. Considerable effort is being expended to identify and determine their distributions and to assess their ecological role as fishery habitat. This session welcomes presentations that describe: 1) distributions of deepwater biogenic habitat in the PICES regions; 2) threats to biogenic habitat species in the area; 3) the ecological role of biogenic structures as habitat for commercial and other species; and 4) the management measures applied or developed to conserve these species and the habitat they provide.

Given the rapid development of ocean observing systems across the North Pacific, it is timely to discuss their use for scientific discovery and ecosystem research, and to describe the technical advancements in ocean sensors, observational platforms, and improvements in data management and exchange. By providing sustained interdisciplinary observations of atmospheric and oceanic processes, observing systems can capture important events influencing ocean ecosystems. Advanced sensors and platforms are creating new opportunities for deciphering ecosystem dynamics. With the increase in data return across observatories, it is critical that data management and interchange be addressed. Papers are welcome on: scientific discoveries made possible by ocean observing systems; observed climate impacts on ocean ecosystems and fisheries; advanced ocean sensors including optical, acoustic and genomic devices; autonomous platforms including underwater vehicles and vertical profilers; data management and exchange; and interoperability among ocean observatories. The intention is to have a mixture of scientific and technical talks on ocean observing systems. The session will be complemented by commercial displays around the theme of ocean observatories.

Numerical models of ocean dynamics are becoming increasingly sophisticated and are now used to forecast future ocean states. The forecasts vary in geographic scale from local embayments to the global ocean, and on temporal scales, from one day to several years. Improvements in ocean forecasting will contribute directly to forecasts of fisheries where the linkages between ocean dynamics, fish migration, and fishery ground formation are understood. Likewise, lower trophic level (LTL) ecosystem models have been coupled to numerical models of ocean circulation and tested at many sites. LTL models can now anticipate the production of planktonic prey and biomass when the state of the ocean is captured accurately by ocean circulation models. Moreover, fish growth and recruitment models are starting to be coupled to LTL ecosystem models. The growing interest in ecosystem-based management, and the need to develop a management/decision policy will no doubt rely upon forecasts from coupled physical-ecosystem models. To fully realize the potential of model-based products for ecosystem-based management, a relatively high predictability of ocean structures is essential. This session will review the current status of operational ocean prediction models, discuss the ability of physical models to forecast ecosystem state and clarify the approaches needed for future studies and improvements. Ideally, we seek papers describing operational forecasts of oceans and/or ecosystem-state and, more importantly, evaluations of their performance. Operational forecasts can be based on numerical or statistical models, and comparisons of these two approaches are welcome.

Phenology and climate change in the North Pacific: Implications of variability in the timing of zooplankton production to fish, seabirds, marine mammals and fisheries (humans)

Co-Convenors:

Ecosystems of the North Pacific Ocean are characterized by strong seasonal variability in productivity. The Inter-governmental Panel for Climate Change projections indicate that substantial changes in phenology (timing events) and the biological interactions that depend on the seasonal cycle are likely. Several mechanistic hypotheses have been set forth to explain changes in fish production in relation to phenology, including "match-mismatch" and "optimal environmental window", yet there have been few tests of these ideas. In light of climate change predictions and recent changes in phenology in some North Pacific ecosystems (e.g., late upwelling in the California Current in 2005/2006), the session will focus on the implications of changes in the timing of seasonal zooplankton production to upper trophic level organisms through changes in their trophic ecology, physiology and behavior. Physical environmental changes that influence phenology also are within the scope of this session. Papers which test hypotheses, present new theoretical treatments, and/or provide models of life history variation are encouraged. In particular, integrated, multi-trophic level, multi-disciplinary analyses are sought. We anticipate publication of the papers from this topic session in primary literature.

North Pacific ecosystems and their response to climate variability have experienced intense study through GLOBEC and similar programs over the past 10 years. The PICES Climate Change and Carrying Capacity (CCCC) Program addressed the question of "how do interannual and decadal variations in ocean conditions affect the species dominance, biomass and productivity of the key zooplankton and fish species in North Pacific ecosystems?".
Ultimately, a goal of the CCCC Program was to forecast possible consequences of climate variability on the North Pacific ecosystem. As the CCCC Program nears completion, it is worthwhile to examine the program’s successes on addressing the key elements: climate change, carrying capacity, and forecasting. This evaluation will provide useful information for moving forward with successor PICES integrative programs like FUTURE: Forecasting and Understanding Trends, Uncertainty and Responses of North Pacific Ecosystems. We invite abstracts that infer processes from patterns and link climate, ocean physics, populations and ecosystems. Provocative abstracts that retrospectively examine the successes and shortcomings of the CCCC Program are welcome, as are more traditional presentations on climate, ecosystems and forecasting.

Lessons learned during MIE-1 and MIE-2: Reconciling acoustics and trawl data

Micronekton is one of the important but largely understudied components of marine ecosystems functionally linking small zooplankton and higher trophic levels. Recent advances in acoustic devices and efforts to standardize sampling gears undertaken by both PICES and ICES communities have made the sampling of micronekton more precise. Nevertheless, the issue of inter-calibrating the growing number of micronektonic gears is still unresolved. The PICES Advisory Panel on Micronekton Sampling Inter-calibration Experiment has organized two field experiments (off Hawaii in 2004 and off Japan in 2005) to collect comparative data for several micronekton sampling gears and a wealth of acoustic information. The main objective of this workshop will be: (1) to finalize the analysis and to compare MIE-1 and MIE-2 data sets; (2) to present and discuss acoustic data sets from both cruises; (3) to compare ICES and PICES inter-calibration experiments; and finally (4) to discuss new developments in the field of micronekton quantitative techniques.

Methods for standardizing trawl surveys to ensure constant catchability

Co-Convenors:
David A. Somerton (U.S.A.), Greg Workman (Canada) and Jin Yeong Kim (Korea)

Invited speaker:
David Reid (Marine Laboratory, Fisheries Research Services, UK)

Standardization in the gear and methodology used to conduct pelagic and bottom trawl surveys is essential for a correct interpretation of catch per unit effort as a measure of relative abundance. In the United States, standardization problems stemming from inaccurate measurement of the towing warps on a NOAA survey vessel resulted in a thorough review of standardization methodology and the development of the National Bottom Trawl Survey Protocols (http://spo.nmfs.noaa.gov/tm/tm65.pdf) governing the operation of all NOAA-sponsored surveys. Subsequently, ICES formed the Study Group on Trawl Survey Standardization to examine the same issue for ICES-sponsored multinational surveys, and to formulate a similar set of standardized operating protocols expected to be published in the fall of 2007. The proposed workshop will review the various pelagic and bottom trawl surveys conducted by PICES member countries, with a focus on the operational protocols used to ensure that survey catchability remains constant over time. Topics to be discussed likely would include a consideration of various instruments to monitor trawl performance, such as acoustic trawl measurement systems, bottom contact sensors and speed through water sensors, as well as trawl design and operation procedures that allow trawl catchability to be robust to environmental variation.

Workshop 3: FIS/MEQ
Comparative analysis of frameworks to develop an ecosystem-based approach to management and research needed for implementation

Co-Convenors:

Invited speaker:
Keith Sainsbury (CSIRO, Australia)

An ecosystem-based approach to management (EBM) is an integrated approach to management of land, water, and living resources that promotes conservation and sustainable use over a broad range of human activities in an ecosystem. Implementation of an EBM for marine ecosystems in the North Pacific Ocean requires a number of steps and activities. An explicit framework that outlines the objectives, legal mandates, and institutional roles and responsibilities is essential. Data requirements and analytical tools need to be developed. This workshop invites speakers who will: 1) highlight existing national and international frameworks for implementation of an ecosystem approach to management; 2) outline the data requirements for such an approach; 3) describe the analytical tools being developed; 4) show the progress in communicating results of EBM activities; and 5) discuss outstanding research gaps for making progress. The workshop will be organized to allow time for keynote summaries of Working Groups results, invited contributions from other PICES groups, insights by other organizations involved in providing integrated ecosystem advice, talks on governance issues and difficulties, socioeconomic issues, etc. During a discussion period, participants are welcome to advise the convenors on the desirability of publishing the results of the workshop in a leading primary scientific journal.

Review of selected harmful algae in the PICES region: III. Heterosigma akashiwo and other harmful raphidophytes

This workshop is the third of an annual series in which Harmful Algal Bloom (HAB) species that impact all or most countries in the North Pacific are discussed in detail. In 2007, we will focus on one species of raphidophytes, in particular, Heterosigma akashiwo. This species is distributed throughout the PICES region and has caused serious damage to finfish aquaculture, resulting in severe economic losses in PICES member countries. The integration of information from each country will advance our understanding of this organism. Topics will include modes of toxicity, distribution, impact (differences between toxic and nontoxic strains), as well as physiology and ecology in each of the member countries. In particular, we would like to identify additional studies needed specifically to define H. akashiwo's mode of toxicity. Comparison with similar raphidophytes, namely Chattonella and Fibrocapsa, will also be included. The workshop will be preceded by a half-day laboratory demonstration on Heterosigma cell and toxin detection.

Marine net primary productivity is a key metric of ecosystem health and carbon cycling and is commonly a function of plant biomass, incident solar flux, and a scaling parameter that accounts for variations in algal physiology. Net primary productivity is defined as the amount of photosynthetically fixed carbon available to the first heterotrophic level, and is the relevant metric for addressing environmental questions ranging from trophic energy transfer to the influence of biological processes of carbon cycling. Long-term monitoring of primary productivity is a high priority for PICES nations because it is one of the essential parameters for the understanding of marine ecosystems and biogeochemistry. Recently, measurement technology of primary production has become extremely advanced through the application of fast repetition rate fluorometers, satellites, buoys, etc. However, inconsistencies between in situ measurements and satellites still exist, and there are some differences between the values obtained with C13 and C14 isotopic methodology.
This workshop will discuss the state-of-the-art primary productivity measurement technology and its application to understanding primary productivity in the North Pacific. Presentations at this workshop should: address techniques for measuring primary productivity, compare in situ and satellite measurements of primary productivity, demonstrate the utility of long time series measurements in understanding ecosystem variability, and describe the application of primary productivity studies to marine ecosystems and biogeochemistry.

Workshop 6: POC/CCCC
Climate scenarios for ecosystem modeling

Co-Convenor:
Jacquelynne R. King (Canada) and Michael G. Foreman (Canada)

This workshop will include invited papers from members of the Climate Forcing and Marine Ecosystem Task Team (CFAME) and the POC Committee Working Group on Evaluations of Climate Change Projections (WG 20) on research activities related to applying output from WG 20 regional climate models, or IPCC (Inter-governmental Panel for Climate Change) global models, to CFAME ecosystem models. CFAME is developing conceptual and empirical models of the mechanisms relating climate forcing to the population dynamics of species and to ecosystem processes. CFAME has focused on four North Pacific ecosystems that represent different dominant physical processes: (1) California Current System (boundary current with upwelling); (2) Kuroshio/Oyashio Current System (boundary currents); (3) Sea of Okhotsk (sea ice cover); and (4) Yellow Sea/East China Sea Region (freshwater input). WG 20 is developing higher resolution regional coupled atmosphere-ocean models forced by IPCC global or regional models. These regional models could provide forecasts of regional parameters (such as SST, sea ice cover, and river discharge) relevant to ecosystem processes. This workshop will facilitate discussion between CFAME and WG 20 members for future collaborative research on forecasting the impacts of climate change (as represented by IPCC projection scenarios) on regional ecosystems and species of the North Pacific.
