Coastal and offshore marine ecosystems of the North Pacific are impacted by increasing temperature, changing iron supply, harmful algal bloom events, invasive species, hypoxia/eutrophication and ocean acidification. These multiple pressures can act synergistically to change ecosystem structure, function and dynamics in unexpected ways that differ from single pressure responses. It is also likely that pressures and responses will vary geographically. A key objective of the FUTURE program is to identify and characterize these pressures in order to facilitate comparative studies of North Pacific ecosystem responses to multiple stressors and how these systems might change in the future.

This session has two primary objectives: 1) to identify key stressors and pressures on North Pacific marine ecosystems, and to compare how these stressors/pressures may differ in importance in different systems and how they may be changing in time; and 2) to identify ecosystem responses to these multiple stressors and pressures, including gaining an understanding of how natural and human perturbations may cascade through ecosystems, and whether there may be amplifiers or buffers which modify the effects of perturbations on marine systems. Papers using conceptual, model-based, observation-based, or experimental-based approaches are welcome, as well as papers which evaluate approaches to linking pressures to ecosystem changes, such as pathways of effects or driver-pressure-state-impact-response models. The overall goal of this session is to obtain an overview of the pressures being experienced by North Pacific marine ecosystems, how these pressures may be hanging with time, variation in these pressures (both singly and in combination) among regions, and the combined effects of pressures, both now and in the future, on the marine ecosystems of the North Pacific.
