Some of the longest and most comprehensive marine ecosystem monitoring programs were established in the Gulf of Alaska following the environmental disaster of the Exxon Valdez oil spill over 30 years ago. These monitoring programs have been successful in assessing recovery from oil spill impacts, and their continuation decades later has now provided an unparalleled assessment of ecosystem responses to another newly emerging global threat, marine heatwaves. The 2014–2016 northeast Pacific marine heatwave (PMH) in the Gulf of Alaska was the longest lasting heatwave globally over the past decade, with some cooling, but also continued warm conditions through 2019. Our analysis of 187 time series from primary production to commercial fisheries and nearshore intertidal to offshore oceanic domains demonstrate abrupt changes across trophic levels, with many responses persisting up to at least 5 years after the onset of the heatwave. Furthermore, our suite of metrics showed novel community-level groupings relative to at least a decade prior to the heatwave. Given anticipated increases in marine heatwaves under current climate projections, it remains uncertain when or if the Gulf of Alaska ecosystem will return to a pre-PMH state.

2019.Development of social-ecological conceptual models as the basis for an integrated ecosystem assessment framework in Southeast Alaska. Ecology and Society 24(3):30. https://doi.ABSTRACT. Integrated ecosystem assessment (IEA) is a framework that organizes and summarizes science to aid in the transition from a traditional single sector toward a holistic management approach known as ecosystem-based management (EBM). An essential step of the IEA framework is the development of conceptual models. These models allow the integration of intrinsically linked social, environmental, and biological components of marine ecosystems that is pivotal to address unsolved questions in fisheries management. We constructed social-ecological conceptual models of relevant commercial and subsistence fisheries for Sitka, a fisheries-based community in Southeast Alaska, by collecting and synthesizing available scientific information, local ecological knowledge (LEK), and qualitative information. We conducted focus groups with key informants in Sitka who had in-depth knowledge of their community's interactions with local fisheries and the structure and function of the surrounding ecosystem. The resulting conceptual models coproduced by scientists and Sitka stakeholders, illustrate the main biological and environmental factors driving the abundance of Pacific halibut (Hippoglossus stenolepis) and Pacific herring (Clupea pallasii) in Southeast Alaska. Furthermore, these coproduced models elucidate how the interaction between Sitka residents and these fisheries affect community well-being. Our models will serve as the basis to assess EBM objectives for Sitka as part of an IEA place-based framework. This study also highlights the importance of integrating LEK into science and potentially into the broader Alaska fisheries management structure.

Although numerous IFQ programs include active participation measures intended to retain or transition fishing privileges to active fishermen, there has been limited research on the efficacy of these measures. This study addresses this gap by examining the impacts of active participation measures in the Alaska halibut and sablefish IFQ program, which were intended to provide for an ultimate transition of the catcher vessel fleets in these fisheries to becoming fully individual-owned and owner-operated. This paper shows that the effectiveness of these measures has been mixed and constrained by apparently strong incentives for many initial recipients of quota shares to effectively lease their annual IFQ allocations (through the use of hired skippers) rather than to sell their quota shares. Perhaps most problematic is the emergence of a class of wholly absentee quota shareholders, who hold only nominal interest in the vessel upon which their IFQ is fished, do not share in the risk of fishing, and continue to profit from the fishery while residing far away from the actual fishing grounds. There is also anecdotal evidence of differing cultural contexts for hired skipper use and second-generation entry between the Seattle and Alaska-based fleets in the Alaska halibut and sablefish fisheries. Wherein acting as a hired skipper may be analogous to an apprenticeship that facilitates quota share acquisition in the Seattle fleet, Alaskan hired skippers may be more analogous to strict lessees, who ultimately compete for quota shares in a market that includes initial recipients and second-generation shareholders both of whom were gifted quota shares.

Over the last three decades, fishing families in the Gulf of Alaska have adapted to numerous multifaceted conditions in response to near constant flux in stocks, markets, governance regimes, and broader sociocultural and environmental changes. Based on an analysis of seven focus groups held across Gulf of Alaska fishing communities, this study explores the variety of strategies that families across the Gulf have employed to adapt to changing conditions from the 1980s to the present day. Furthermore, the study examines how those strategies have evolved over time to accommodate cumulative effects and synergisms. While families continue to employ long-standing adaptation strategies of fisheries portfolio diversification and increasing effort, they are also integrating new adaptations into their framework as changing management systems, demographics, and technologies shift how choices about adaptations are made. This study also demonstrates how adaptations have implicit intra- and inter-personal well-being tradeoffs within families that, while potentially allowing for sustained livelihoods, may undermine other values that individuals and families derive from fishing.
