Baffin Bay (Inuktitut: Saknirutiak Imanga; Greenlandic: Avannaata Imaa; French: Baie de Baffin), located between Baffin Island and the west coast of Greenland, is a marginal sea of the North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador narrower Nares Strait connects Baffin Bay with the Arctic bay is not navigable most of the year because Average depth: m (2, ft). GEOL Geologic Structures and Interpretation of Geologic Maps Pre-lab Reading 1 Lab 8: Geologic Structures and Interpretation of Geologic Maps Purpose The purpose of this exercise is to introduce you to geologic maps and the principles of their interpretation. By the time you have completed this exercise you will be able to recognize different geologic structures from their outcrop patterns.

Unlike the deep mantle and crustal sections discussed above, which we have only been able to examine by indirect seismic methods, it has been possible to study the uppermost km of the section at Site directly because the section was drilled and continuously cored to a depth of m during Leg in order to install the borehole seismic observatory in basement below the influence of.

This textbook is designed to aid the student in geological map interpretation. The book starts with basic concepts such as dip and strike, and progresses through a variety of exercises based on folds, faults and unconformities, up to and including the interpretation of Geological Survey Maps.

In order to give a sense of reality to the text, frequent reference is made to actual examples on. The Moho-proxy maps using the two sets of depth to basement constraints (Figs 4a and b) show a relatively uniform Moho depth of 12 km in the centre of the Labrador Sea with a deeper Moho (20 km and greater) beneath the Davis Strait and for the offshore extension of the Grenville Province of southeastern Labrador.

These interpretation maps originated in the mid s when large airborne geophysical, magnetic and radiometric surveys were commonplace. Deep seismic reflection profiling has been used to outline the main features of the basement topography of the Labrador Sea. Two major sedimentary reflectors, tentatively dated as Paleocene and Eocene, are correlated throughout the survey.

Geophysical data collected from to during a systematic mapping program of the Labrador Sea have been analysed to investigate its geological history and evolution.

The data have been used to establish the location of the ridge axis, the age of the ocean floor, and the direction of movement of Greenland relative to North America.

The Geological Survey of Newfoundland and Labrador is a scientific research agency that is part of the Department of Natural Resources of the Government of Newfoundland and Labrador.

Newfoundland and Labrador is the easternmost province in Canada. It is bordered by the Atlantic Ocean, Labrador Sea, Gulf of St. Lawrence, and Quebec to the west and south. Newfoundland and Labrador consists of two parts: 1) the island of Newfoundland, and.

That is another reason why geologic maps are so interesting: each one is a customized solution to a particular set of needs, and one of those needs, in every case, is that the map be pleasing to the eye.

Thus geologic maps, especially the kind that are still printed on paper, represent a dialog between truth. Source: Journal of Geophysical Research: Oceans A set of instruments designed to measure conductivity, temperature, and depth is lowered Author: Emily Underwood.

An ocean (from Ancient Greek Ὠκεανός, transc. Okeanós) is a body of water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans.

VARNES ABSTRACT A map is a spatial classification that transmits information about features at or near the earth's surface for a defined purpose.

Transmission is effective only if map maker, map,Cited by: The Labrador shelf and slope Mesozoic sedimentary area is divided by the Okak Arch into two large basins, the Saglek Basin and the Hopedale Basin.

The Hopedale Basin is the more southerly basin and extends from the Cartwright Transfer Fault Zone (CTFZ) in the south to the Okak Arch in the North: a distance of approximately kilometres from 55° to 59° latitude North. The mineral resources of Newfoundland and Labrador are a direct product of its geological history.

It illustrates the composition, structure, and history of geologic material or a portion of the Earth’s surface. Most important, a geologic map shows how geologic parameters change spatially within the area of interest.

Two very different types of information are displayed on a geologic map.
