Coupled North Atlantic slope water forcing on Gulf of Maine temperatures over the past millennium

Abstract To investigate ocean variability during the last millennium in the Western Gulf of Maine (GOM), we collected a 142-year-old living bivalve (Arctica islandica L.) in 2004, and three fossil A. islandica shells (calibrated 14 CAMS = 1030 ± 78 AD; 1320 ± 45 AD; 1357 ± 40 AD) for stable isotope...

Description
Summary:Abstract To investigate ocean variability during the last millennium in the Western Gulf of Maine (GOM), we collected a 142-year-old living bivalve (Arctica islandica L.) in 2004, and three fossil A. islandica shells (calibrated 14 CAMS = 1030 ± 78 AD; 1320 ± 45 AD; 1357 ± 40 AD) for stable isotope and growth increment analysis. A statistically significant relationship exists between modern GOM temperature records [shell isotope-derived (30 m) (r =-0.79; P \ 0.007), Prince 5 (50 m) (r =-0.72; P \ 0.019), Boothbay Harbor SST (r =-0.76; P \ 0.011)], and Labrador Current (LC) transport data from the Eastern Newfoundland Slope during 1993–2003. In all cases, as LC transport increased, GOM water temperatures decreased the following year. Decadal trends in the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal
