Abstract

Marine life is being affected by changes in ocean conditions resulting from changes in climate and chemistry triggered by combustion of fossil fuels. Shifting spatial distributions of fish species is a major observed and predicted impact of these oceanographic changes, and such shifts may modify fish community structure considerably in particular locations and regions. We projected future range shifts of pelagic marine fishes of the Northeast Pacific shelf seas by 2050 relative to the present.

Abstract

Three independent modeling methods—a nutrient-phytoplankton–zooplankton (NPZ) model (NEMURO), a food web model (Ecopath/Ecosim), and a bioenergetics model for pink salmon (Oncorhynchus gorbuscha)—were linked to examine the relationship between seasonal zooplankton dynamics and annual food web productive potential for Pacific salmon feeding and growing in the Alaskan subarctic gyre ecosystem.

Abstract

There is growing recognition that the Arctic is threatened by multiple human impacts including climate change and increased activities resulting from greater access due to retreating sea ice. Arctic sea ice cover has declined about 3% per decade over the satellite record (1979-present), with the six lowest annual sea ice minima occurring in the last 6 years (2007-12). The Alaska Arctic contains large petroleum reserves, and human activities related to energy extraction are expected to increase in the near future.

Organization Overview: 

ASAP helps build essential climate resilience for communities across the country by focusing on connecting and supporting the individuals. We provide a platform for climate adaptation leaders to interact, share what’s working, and collaborate with their colleagues.

Adaptation work: 

ASAP Members across the United States are working to prepare for the impacts of climate change and make their communities, regions, states, and the country more resilient to those changes. For each of us, the story is different but similar. ASAP Members realize that climate change is one of the most critical issues of our time and that it will affect many aspects of our jobs and our communities. We work within our own sector and across many other sectors.

Abstract

A recent NOAA study found that by 2040, Alaskan shellfish hatcheries may no longer be sustainable because of ocean acidification, unless serious mitigation efforts are put in place. We recently reported on a hatchery in Oregon that’s become a model for adapting to these different conditions. But the long term solution may actually lie in shellfish genes. Evolution and resiliency are the buzzwords for a sustainable mariculture industry in Alaska, a state that is particularly vulnerable.

Abstract

The implementation of sector management in New England’s groundfish fishery sparked dramatic changes in every aspect of the industry, forcing an unprecedented level of innovation and adjustment. The switch from the effort controls of days-at-sea to the output controls of sector allocation, prompted primarily by federal mandates, changed everything from a fisherman’s pre-trip planning to business arrangements that get fish from the vessel to the table.

Abstract

In California much work is being done at the local and state levels to mitigate the effects of climate change, and develop adaptation strategies. In particular, California recently released for public comment “Safeguarding California: Reducing Climate Risk” – an update to the 2009 California Climate Adaptation Assessment. In it, decision makers specifically highlight the need to improve understanding of climate risks to biodiversity and habitat, among other recommendations.

Abstract

What is ocean acidification? Every day, the ocean absorbs approximately one-third of the carbon dioxide we put into the atmosphere when we burn fossil fuels and clear land. When carbon dioxide dissolves in seawater, it becomes an acid. This acid is lowering the pH of ocean water. pH is an important vital sign of ocean health, and its rapid change raises a red fl ag. Scientists refer to this shift in ocean chemistry as ocean acidifi cation.

Abstract

In winter 2011-2012 the Alaska Marine Conservation Council (AMCC) sponsored community roundtable discussions on ocean acidification and Alaska fisheries in the fisheries-dependent communities of Homer, Kodiak and Dillingham in southern Alaska.
