A doctoral dissertation from the Univ. of Maine reconstructs temperatures of the Gulf of Maine during the past 1000 years and finds temperatures were about  2°C warmer than the present during the Medieval Warming Period 1000 years ago. According to the author, 

"These data indicate that the Gulf of Maine has undergone considerable changes during the last millennium, and specifically the shell-derived temperature record suggests that the Gulf of Maine has cooled by ~ 2 °C."
