Sea-Floor Sunday #36: Gulf of Maine

November 30, 2008

I hope all those in the States had a nice Thanksgiving holiday. I spent the long weekend in Boston visiting some family. I am in the airport now but, unfortunately, not heading home. I will be traveling for the next six days but may be able to blog a bit here and there. Regular posting should resume next week.

In the spirit of my visit to Boston, this week’s Sea-Floor Sunday shows the Gulf of Maine offshore of southeastern Canada and New England.

Although I haven’t studied this area in any detail, my guess is that the Northeast Channel is a similar to the Laurentian Channel, a glacial outwash feature that formed during the Last Glacial Maximum lowstand in sea level during the late Pleistocene (~20,000 yrs ago), when the coastline was out at the edge of the continental shelf.

    and the georges bank does a wonderful job at keeping the warm water of the gulf stream nice an far from the Maine coast. but at least the fishing is good.

    I think that Cape Cod (and assoc. islands) and Gearge’s Bank are the submerged moraine, so that channel may be the most southerly point where the icesheet discharged directly into the ocean.
