The effect of continental shelves on tides

Deep Sea Research Part A. Oceanographic Research Papers, 1981
Abstract Coastal tides are influenced by several factors and one of the most important of these is the character of the adjacent continental shelf. A continental margin theory is derived and used to discuss several different aspects of the effect “smooth” continental shelves have on tides. The main results are as follows.

Continental Slopes and Shelves

The Geographical Journal, 1941
AROUND every continent is a relatively flat but gradually shelving sub-?~^-marine belt running out from the low tide mark. Its width varies greatly, but it is usually between 50 and 150 miles; its outer edge is arbitrarily but conveniently defined by the 100-fathom line.

Sediments of the Continental Shelves

Geological Society of America Bulletin, 1932
Introduction Many geologists have stated that marine sediments vary from coarse to fine directly as the distance from shore and the depth of water increase. Such gradation seems so reasonable in view of our knowledge of waves and currents that what is practically a geologic axiom has come into existence.

Origin of Continental Shelves

AAPG Bulletin, 1946
ABSTRACT In order to explain the common occurrence of a shelf edge at the isobath of 200 meters, a widespread subsidence of the shelf area in the order of 100 meters has to be assumed, apart from the influence of eustatic changes of sea-level.

Glaciation of the continental shelves (part II)

Polar Geography and Geology, 1984
Over the past two decades, in no small part due to the author's efforts, considerable evidence has accumulated to indicate that a significant proportion of the total mass of the Pleistocene ice sheets lay on the continental shelves rather than on the continents per se.

Characteristics of Continental Shelves and Slopes

AAPG Bulletin, 1965
ABSTRACT One of the most important and interesting geological questions awaiting solution is that of the origin of continental shelves and slopes. Just as for other geological features, more than a single origin is involved for different areas or for different times. Data on structure, composition, and topography provide the clues for

Controls on the degree of fluvial incision of continental shelves

Computers & Geosciences, 2008
During sea-level low stands continental shelves were dissected by a network of channels somewhat resembling today's coastal plain streams. The network was subsequently buried or erased by marine processes during sea-level transgression, so that only some tracts are still conserved in the geological record.

Nature of Continental Shelves: DISCUSSION

AAPG Bulletin, 1951
In connection with a discussion of petroleum reserves attributed to shelf areas on the basis of the calculated volume of sediments, concludes that continental shelves are the seaward extension of land masses and that oil possibilities in the downwarped continental margins are related to favorable structure and stratigraphy of the adjacent land area.

Glacial Troughs of the Continental Shelves

The Journal of Geology, 1931
Submarine valleys may be classified into three groups. One group resembles youthful river valleys, another fault grabens, and a third glacial troughs. There are many reasons for believing that the valleys of this last group have been shaped by glacial excavation. They are found exclusively off glaciated coasts. They contain the deep-rimmed depressions,
