Thanks. I do know the location of Les Ecoumins, but looking at a map it appeared to be on the flow path of the river. When I checked the Burgeo Bank reading:
47.28 N 57.35 W (47°16'7" N 57°21'9" W)
http://www.ndbc.noaa.gov/station_page.php?station=44255
is reporting 61F.
In other words, the river flowing from the West of LE is 75F, and water to the E of LE, salt water, is 61F.
Do you understand my confusion? There would have to be a major cold influx, that somehow doesn't affect Burgeo Bank, yet is sufficient to radically cut the very warm water temps coming down the St. Lawrence. That's why I had asked if you were there on Holiday (long weekend) this August, or if there was some odd local phenomenon, since met buoys are normally not going to be > 20 degrees erroneous and Burgeo Bank would seem to be a reasonable "bracket" location; I would expect LE temp to be between the 75 and 61, and my gut feel would be that it would be a decent number of degrees above Burgeo Bank, picking up the influence of that warm SL river water.
I'm an engineer by trade, tend to do geek things like look at buoy data. If I hear of 40F water in the middle of 75 and 61F water, I by nature ask what causes the effect. I wonder if there is a glacial river providing a feed at that location, or something similar.
(Not disagreeing to be disagreeable, but to understand what is so special about the location, to make the water much colder than surrounding temperatures)
