“A Coast Beyond Compare is an amazing book: a textbook, a reference book and an art book in one. Beautifully illustrated, it honors one of the world’s most spectacular coastlines. The book covers the evolution Alaska coast from the beginning of the universe (really!) to the puts the coast in context of global plate tectonics and right down to centimeter-scale ripples.

This highly active tectonic setting is the dominant influence on the nature of the depositional systems and the sediment composition along the inlet's shoreline.

The km of shoreline of Lower Cook Inlet was subdivided into erosional (45%), neutral (38%), and depositional (17%) by: Cook Inlet (Fisher and Magoon ) and the Sea of Okhotsk (Watson and FujitaEichelberger et al. ) occur within back-arc settings in which extensional tectonics are operative.

The Gulf of Cambay occupies a rift basin that was formed in the early Mesozoic during and after the separation of India from Gondwanaland (Biswas ).

Shoreline Sedimentation within a Forearc Embayment, Lower Cook Inlet, Alaska. Miles O. Hayes, Jacqueline Michael. ABSTRACT. Lower Cook Inlet is a forearc embayment associated with the northeast extension of the Aleutian volcanic arc.

This highly active tectonic setting is the dominant influence on the nature of the depositional systems and the. Click on the book chapter title to read more. The Castle Mountain fault is a km-long, right-lateral fault that forms the northern boundary of the Cook Inlet basin and Matanuska Valley, Alaska.

Fault gouge and fault rock at six localities contain the clay minerals illite, smectite, chlorite, and interstratified illite/smectite. A regional classification of shoreline segments along the Alaskan Beaufort Sea Coast was developed as the basis for quantifying coastal morphology, lithology, and carbon and mineral sediment fluxes.

We delineated 48 mainland segments totaling 1, km, as well as 1, km of spits and islands. Mainland coasts were grouped into five broad classes: exposed Cited by:   Offshore tracts in Alaska's lower Cook Inlet are scheduled to be opened for exploratory petroleum drilling in the near future.

Because of the potential for oil spills resulting from this activity, a field study of the coastal zone was conducted in June A total of km of shoreline was classified into 3 types: erosional (45 percent), neutral (38 percent), and Cited by: Coastal morphology and sedimentation, lower Cook Inlet, Alaska, with emphasis on potential oil spill impacts: Tech.

It is bordered on the west and northwest by the Alaska Range, on the northeast by the Talkeetna Mountains, and on the southeast by the Kenai-Chugach Mountains.

Cook Inlet is an extremely dynamic, high-energy. Co-seismic subsidence occurred over an elongate region including the Kenai Peninsula and most of Cook Inlet. In greater Anchorage, the largest urban area in Alaska, co-seismic subsidence ranged from m (Plafker, ).

Augustine Volcano, a small island volcano located in Cook Inlet, Alaska has produced approximately 11 flank-failure debris-avalanches over the last 2, yrs (BP) that were large enough to reach the coast of the island and enter the sea.

Each debris avalanche conceivably could have triggered a tsunami. Ina tsunami generated by an eruption and flank-failure. Not only have the beaches eroded quickly during the past years, but erosion rates have increased significantly over time. The greatest changes have been observed along the tribal reservation, where USGS scientists and their collaborators reported in a article that erosion averaged nearly 2 ft per year between and (see Warrick and others.

In addition, Cook Inlet exhibits the largest tidal fluctuations in the United States, and as a result, the nearshore regions encounter significant flooding and drying which poses threats to a variety of activities in the coastal regions.

A coupled wind-wave-current system is developed to obtain daily forecasts of waves and circulation patterns. of lower Cook Inlet are: Kenai Peninsula, to 2, Kamishak Bay­ Shelikof Strait, to 2, and Kodiak Archipelago, to 6, The estimated sea otter population of Alaska istoCook Inlet in Alaska has been identified as a prime site in the U.S.

for potential tidal energy development, because of its enormous tidal power potential that accounts for nearly one-third of the national total. As one important step to facilitate tidal energy development, a tidal hydrodynamic model based on the unstructured-grid, finite-volume community ocean model.

The scope of this project included lower Cook Inlet, Norton Sound and the southern part of the Chukchi Sea in addition to the three shelf areas (Gulf of Alaska, S.
