Up to about 8, years ago, the Gulf of Maine was a huge inland basin called the DeGeer Sea, with only a narrow opening to the Atlantic. When the estuaries, flats, barrier beaches, and salt marshes were flooded, the coastal zone became unproductive.

To assess the reliability of elemental fingerprinting for identifying mussel source locations in the Gulf of Maine, we collected mussels at 7 sites between northern Maine and Cape Cod, Massachusetts, USA (Fig. 1).All sites supported mussel populations inhabiting coastal, intertidal, hard-bottom habitats that were on or adjacent to rocky headlands, with the exception of Cited by:

National Oceanic and. Introduction. The Gulf of Maine (GOM) is a mid-latitude marginal sea that is bounded by the coastlines of New England and Atlantic Canada.

Like other northern-hemisphere marginal seas, the general circulation of the GOM is cyclonic (Bigelow, ).The principal cyclonic circulation cell is centered in the eastern GOM and has accordingly sometimes been referred to as the Jordan Basin Gyre (e Cited by: Deep seismic reflection and magnetic data suggest that the Gulf of Maine is underlain by four crustal blocks of differing reflection and magnetic character.

Two of these blocks, the Gulf of Maine. 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 by: 4.

Crustal structure of the Gulf of Maine Pre-Triassic terranes. Deep seismic reflection and magnetic data indicate that the basement of the Gulf of Maine region was formed as a consequence of the closure of the proto-Atlantic at the end of the by: The Gulf of Maine has its own oceanographic characteristics, distinct from those of the open Atlantic (1).

The Gulf of Maine has a rich history. We can trace the formation of the modern day Gulf of Maine by beginning in the Cenozoic Era (Fig. The Cenozoic, our present era, is divided into two geologic periods: Tertiary and Quaternary.

Introduction [2] The Gulf of Maine (GOM) is a continental shelf sea on the east coast of North America, situated between Cape Cod, Massachusetts, and Nova Scotia, Canada [Townsend et al., ].Here as in many areas of the northwest Atlantic, it is believed that the stabilization of the water column and the initiation of a phytoplankton bloom are linked [Ji et al., ].Cited by: 5.

Fig Small Point, Maine, cropped to the center of the Small Point Crater off Maine & Mass.

USGS Image. The Small Point Investigation is on a structure off the coast of Maine. There is evidence implying a large impact crater in the Gulf of Maine. Its most probable age is K-T boundary, but it lacks definitive ages from impact materials.

A Brief Overview of the Physical Oceanography of the Gulf of Maine by David A. Brooks Department of Oceanography Texas A&M University ound and Setting The Gulf of Maine is a marginal sea that is nearly cut off from the Atlantic Ocean by Georges and Browns Banks.

The gulf is well known for its anomalously cold waters, a fact that is. Maine region has fewer, smaller salt marshes than the southeastern U.S. coast because glaciers scoured the bedrock of the Gulf of Maine watershed.

Plant species are. The Gulf of Maine Council on the Marine Environment, an alliance between the states and provinces, was established in November by the governors and premiers within the Gulf of Maine, and has recognized the problem of increasing pressure on the ecosystem's health.

One of the Council's major goals has been the development of a land-based. Alexandrium fundyense blooms.

Time: Students will need the equivalent of at least two class periods of out-of-class.Deep seismic reflection and magnetic data suggest that the Gulf of Maine is underlain by four crustal blocks of differing reflection and magnetic character.

Two of these blocks, the Gulf of Maine fault zone and adjacent central plutonic zone, can be correlated with Avalonian rocks in southern New England and New Brunswick. The boundary between them, the Fundy fault, projects onshore near the.
