Marine Geology: Exploring the New Frontiers of the Ocean by Jon Erickson

By Jon Erickson

This absolutely revised and extended version of Marine Geology heavily examines the interrelationship among water and its lifestyles varieties and geologic constructions. It seems at a number of principles for the foundation of the Earth, continents and oceans, and the way those techniques healthy into the starting place of the universe. From substantial submarine canyons to ocean volcanoes, this quantity covers the whole realm of undersea landscapes and existence varieties.

Interaction of ocean waves and wind

This can be the 1st ebook to explain intimately the two-way interplay among wind and ocean waves and indicates how ocean waves impact climate forecasting on timescales of five to ninety days. Winds generate ocean waves, yet even as airflow is changed as a result of lack of power and momentum to the waves; hence, momentum loss from the ambience to the sea is determined by the kingdom of the waves.

Marine Geology: Exploring the New Frontiers of the Ocean

This absolutely revised and increased version of Marine Geology heavily examines the interrelationship among water and its lifestyles types and geologic constructions. It appears to be like at a number of principles for the foundation of the Earth, continents and oceans, and the way those tactics healthy into the beginning of the universe. From mammoth submarine canyons to ocean volcanoes, this quantity covers the whole realm of undersea landscapes and existence types.

Deep-water contourite systems: modern drifts and ancient series, seismic and sedimentary characteristics

Contourites are a common yet poorly identified workforce of sediments associated with the motion of robust backside currents in deep water. even if we all know they're specially universal alongside continental margins and during oceanic gateways, they've been surrounded by means of the debate when you consider that they have been first famous within the early Nineteen Sixties.

About 50 million years after rifting began, the infant North Atlantic had achieved a depth of 2 miles or more. It was bisected by an active midocean ridge system that produced new oceanic crust as the plates carrying the surrounding continents separated. The entire process of opening the South Atlantic took place in a span of just 5 million years. The South Atlantic continued to widen as more than 1,500 miles of ocean separated South America and Africa. Africa moved northward, leaving Antarctica (still joined to Australia) behind, and began to close the Tethys Sea.

They revealed that instead of miles of silt and mud, the oceanic crust contained only a few thousand feet of sediment. During the height of the cold war in the late 1950s,American and Russian oceanographic vessels mapped the ocean floor to enable ballistic missile submarines to navigate in deep water without grounding on uncharted seamounts. During heightened cold war tensions, when Russian aircraft shot down a Korean civilian airliner over Sakhalin Island on August 30, 1983, killing all 269 passengers and crew, an unprecedented search for the downed aircraft was conducted using the robotic submersible Deep Drone (Fig.

27) and pulled through elaborate obstacle courses in the dark abyss. However, the instruments were damaged or lost at an alarming rate. The most sophisticated device, called Deep Tow, carried sonar, television cameras, and sensors for measuring temperature, pressure, and electricity. During operation over the East Pacific Rise off the coast of Ecuador, the camera sled “flew” into a hot plume of water. Upon further exploration, photographs taken by Angus revealed a lava field scattered with large white clams.
