S1: Science Board Symposium (0.75 day)
Beyond the continental slope - complexity and variability in the open North Pacific Ocean

Co-Convenors: R. Ian Perry (SB), Vladimir I. Radchenko (BIO), Yukimasa Ishida (FIS), John E. Stein (MEQ), Kuh Kim (POC), Igor I. Shevchenko (TCODE), and Harold P. Batchelder and Suam Kim (CCCC)

S2: BIO Topic Session (1 day)
Mechanisms that regulate North Pacific ecosystems: Bottom up, top down, or something else?

Co-Convenors: Douglas DeMaster, George L. Hunt, Jr. (U.S.A.), Michio J. Kishi (Japan), Jeffrey M. Napp (U.S.A.) and Andrew Trites (Canada)

Within the PICES region, dramatic changes have been observed in the past 50 years in the structure and function of marine ecosystems. In an effort to understand what caused these changes, various hypotheses have been proposed as controlling mechanisms for entire ecosystems or for particular components of the ecosystems (e.g. fish stocks and apex predators). Each of the hypotheses (e.g., Trophic Cascade, Oscillating Control, Nutritional Stress and Regime Shift), has at its core, a fundamental assumption that control is the result of bottom-up, top-down, or a wasp waist trophic pyramid restriction. Is it really that simple? Are these hypotheses testable? Will they lead us to a predictive capability? This session will critically examine these hypotheses, as applied to ecosystems and important marine populations from the western and eastern North Pacific Ocean. The goal is to review, based on observations and model results, the basic assumption (source of control), and to evaluate the strength and weaknesses of the individual hypotheses. The session will also discuss how the different control mechanisms might affect the ability of managers to maintain sustainable fisheries in the region. The possibility of publishing the results in a special issue of a leading international journal will be explored.

Invited speakers:
Philippe Cury (Centre de Recherche Halieutique Méditerranéenne et Tropicale, IFREMER & Université Montpellier II, France) - Who is controlling whom in marine ecosystems and how to quantify it?
Bernard A. Megrey (Alaska Fisheries Science Center, National Marine Fisheries Servive, NOAA, U.S.A.) - Evaluating the role of top-down versus bottom-up ecosystem regulation from a modeling perspective
Yasunori Sakurai (Hokkaido University, Japan) - Why do ommastrephid squids increase in abundance during warm regimes?
