Geologic evolution of the Gulf of Maine region

Earth-Science Reviews, 2008
Abstract In this study we reconstruct the evolution of the northern New England passive margin whose development has been influenced by Pleistocene glaciations. The morphology of the northern New England shelf is rather unique consisting of a inner lowland, the Gulf of Maine, with an average depth of 150 m and an area of 90,700 km2 and Georges Bank ...

Explosion Measurements of Crustal Structure in Maine and the Gulf of Maine

The Journal of the Acoustical Society of America, 1961
A series of 61 explosions were fired in the Gulf of Maine during June and July, 1961, by the U. S. Navy and the U. S. Coast Guard, forming a detailed line of shot points along an azimuth 129° true from Thomaston, Maine. These shots were recorded by a line of portable seismic stations 70 km long on the landward extension of the shot line.

Submarine Topography of Eastern Channel, Gulf of Maine

The Journal of Geology, 1957
Topography of Eastern Channel between Browns Bank and Georges Bank is similar to submarine glaciated valleys elsewhere, notably Cabot Trough in the Gulf of St. Lawrence. It is possible that glacial ice in these offshore regions was confined to deep embayments such as the Gulf of Maine and that it did not extend out over the continental shelf as a sheet

Dynamic oceanography of the Gulf of Maine

Eos, Transactions American Geophysical Union, 1927
Within the last few years the mathematical applications of Bjerknes' hydrodynamic theory to ocean‐currents have been so simplified by his followers, especially by Ekman, Helland‐Hansen, Sandstrom, Hesselberg and Sverdrup, and by Smith, that no oceanographer need longer fear to give dynamic consideration to the seas with which he is concerned ...

Sediments of the Gulf of Maine: ABSTRACT

AAPG Bulletin, 1965
The Gulf of Maine is a rectangular depression on the continental shelf about 180 miles long and 120 miles wide. Georges Bank, Browns Bank, and the Nova Scotian Shelf, all shallower than 100 meters, separate the Gulf from the Atlantic Ocean to the southeast. Glacial scouring has accentuated the highly irregular bottom topography, and numerous basins 200

Triassic Rift Structure in Gulf of Maine

AAPG Bulletin, 1975
Interpretation of seismic-reflection profiles across the Gulf of Maine and Georges Bank reveals that the region underwent major crustal rifting during the Triassic Period. Three rift systems are delineated: the Fundy fault system extending southwest from the Bay of Fundy to the central Gulf of Maine, the Wilkinson basin system striking north-south in ...

Vernal circulation in the Gulf of Maine

Journal of Geophysical Research: Oceans, 1985
The circulation in the Gulf of Maine has an important baroclinic component. It appears to be driven mostly by the density contrast between high‐salinity slope water which enters from the Atlantic and fresher waters which are formed in the Gulf or which enter from the Scotian shelf.

SEISMIC-REFRACTION PROFILE ACROSS THE GULF OF MAINE

Geological Society of America Bulletin, 1953
On August 11, 1949, the USS MENTOR shot one partially reversed refraction profile across the northern Gulf of Maine, from a point southeast of Portland, eastward beyond Matinicus Rock (Fig. 1, shot 13). Three portable seismographs were set up at Falmouth, near Portland, Maine, on Mt. Desert Island, Maine, and at Crowell, Nova Scotia. The Crowell

Foraminiferal Studies: Wilkinson Basin, Gulf of Maine: ABSTRACT

AAPG Bulletin, 1971
Sediment samples from a 280-m core taken in the Wilkinson basin, Gulf of Maine, have been studied for foraminiferal content. The sediments are dusky yellowish-brown silty clay and presumably represent particles carried by glacial meltwater into the Atlantic Ocean during the latest period of continental deglaciation.
