Resilience and Adaptation of a Coastal Ecological-Economic System in Response to Increasing Temperature
This project aims to understand how abrupt temperature changes, as well as the long-term warming trend, impact marine ecosystems and fisheries. Fisheries provide a two-way connection between changing ocean environments and local economies. As the distribution and abundance of species change, where, when, and how many fish are caught will change. Fisheries also respond to economic conditions or management policies, leading to feedbacks onto fish populations. In order to understand the impact of warming on fisheries ecosystems, it is essential to account for dynamical interactions between populations, fisheries, and markets. Our work focuses on the Gulf of Maine, a region that is warming rapidly and has experienced previous single-year warm events (e.g., 1999, 2012). These warming events have had a profound impact on the region’s oceanography, species distributions, and the valuable lobster fishery. Understanding the environmental, ecological, and economic linkages in the lobster fishery is a central goal of our project. Towards this goal, we will do significant work to evaluate spatial and temporal variability in surface and bottom temperatures and their influence on changing distributions of species that interact with lobsters (e.g., groundfish) along the Northeast Shelf. This project is funded by the National Science Foundation.
Key strategies and actions:
- Incorporate climate change into stock assessments (e.g., document new species ranges and abundance, document food web impacts)
- Monitor to detect species presence and absence correlated to changing environmental conditions
- Diversity fisheries and/or livelihoods (e.g., ecotourism, promote new fishing opportunities for non-native and invasive species)
