RAPID: Effect of a Very Low NAO Event on the Abundance of the Lipid-Rich Planktonic Copepod, Calanus finmarchicus, in the Gulf of Maine

RAPID: Effect of a Very Low NAO Event on the Abundance of the Lipid-Rich Planktonic Copepod, Calanus finmarchicus, in the Gulf of Maine
<p>"The copepod, <em>Calanus finmarchicus</em>, is a dominant member of the plankton in the Gulf of Maine, (GoM), despite its location at the southern edge of the species' subarctic range. Wilkinson Basin, one of the three deep basins in the GoM, harbors very high concentrations of the early developmental stages of <em>C. finmarchicus</em> in the summer through winter and serves as a source of <em>C. finmarchicus</em> to GoM coastal ledges and banks. A recent study based on <em>C. finmarchicus</em> habitat characteristics across the North Atlantic predicts that climate-driven change will force the distribution of <em>C. finmarchicus</em> northward out of the GoM over the next several decades. However, the oceanographic and life history responses of C. finmarchicus to environmental variability in the Gulf are complex and largely unknown. The research in this RAPID proposal takes advantage of a rare opportunity to test a hypothesis about the control of <em>C. finmarchicus</em> abundance in the GoM from climate change related external forcing. The hypothesis states that a distinctly lower <em>C. finmarchicus</em> abundance follows, with a two-year lag, the occurrence of a very negative North Atlantic Oscillation (NAO). The specific processes that causally connect low <em>C. finmarchicus</em> with the NAO are not known. The research here tests the prediction that <em>C. finmarchicus</em> abundance will be very low in Wilkinson Basin in 2012, two years after one of the most negative NAOs on record, dating back to the 1860?s. Field observations in the form of a time series of measurements of hydrography, food availability and <em>C. finmarchicus</em> stage abundance will be taken at a fixed station in Wilkinson Basin and in the Maine coastal region, supported by measurements taken on the Scotian Shelf. A research survey, coordinated with a scheduled cruise in the Gulf of Maine in September, 2012, will take additional collections in Wilkinson Basin and throughout the GoM. Frozen and ethanol preserved samples of <em>C. finmarchicus</em> will also be collected for population genetic studies. The abundance results will be compared with historical time series and survey data collected over the past two decades, confirming or refuting the expectation of extreme NAO influence on GoM <em>C. finmarchicus</em> populations." <em>(from the Award abstract)</em></p>
