HMSC Research Seminar-A Treasure Trove Revealed: Using Archived Data To Expand Our Understanding Of the California Current Ecosystem

Speaker: Beth Phillips, Interdisciplinary Research Fish Biologist, Northwest Fisheries Science

Topic: A Treasure Trove Revealed: Using Archived Data To Expand Our Understanding Of the California Current Ecosystem

Datasets that span broad temporal and spatial scales can provide important insights on ecosystem variation and inform ecosystem-based fisheries management. NOAA Fisheries Northwest Fisheries Science Center and Fisheries & Oceans Canada conduct biennial joint U.S.-Canada Integrated Ecosystem & Acoustic-Trawl surveys for Pacific hake. The survey has been conducted since 2003 and operates between Point Conception in southern California to Haida Gwaii in northern British Columbia, surveying most of the California Current during June to September. The survey collects data to support management of commercially important Pacific hake, including a vast amount of oceanographic, acoustic, and biological data that can be used for other ecological research. I will describe my efforts to use this archived data to develop a novel time series of euphausiid (krill) abundance and discuss the insights I gleaned from analyzing this dataset. The simultaneous collection of krill and hake data allows for a direct evaluation of relationships between an important prey item in the CCE and an abundant predator, and I will also share these results. Because krill are key prey items for a wide range of seabirds, marine mammals, and commercially important fish, I will also discuss additional research projects that this valuable dataset will support to expand our understanding of the California Current Ecosystem and inform ecosystem based fisheries management.
