Sea surface and air temperature records for the Gulf of St. Lawrence. Sea surface temperature averages for the Gulf of St. Lawrence from May to November, from 1 km2 resolution NOAA AVHRR imagery, are available since 1985 (blue line) and show a 2ºC warming trend between a cooler and a warmer period centered around 1993. 2010 Canadian Marine Ecosystem Status and Trends Report

Sea surface and air temperature records for the Gulf of St. Lawrence. Sea surface temperature averages for the Gulf of St. Lawrence from May to November, from 1 km2 resolution NOAA AVHRR imagery, are available since 1985 (blue line) and show a 2ºC warming trend between a cooler and a warmer period centered around 1993. The series is well correlated with the average air temperature at nine stations selected around the Gulf available since 1945 (green line), with air temperature data from Charlottetown available from three stations since 1873, and with air temperature data from Pointe-au-Père collected since 1876.
