Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
Turnagain is characterized by remarkably large tides of up to 40 feet (12 meters) which are the largest tides in the United States. The flood tide often begins with a tidal bore especially on large tides with a strong east wind, which has a height of 6 feet (1.8 m) at times, and runs in from the west at a speed of 5–6 miles (8.0–9.7 km) an ...
View across Cook Inlet at low tide from downtown Anchorage, Alaska (September 2005) The Cook Inlet beluga whale is a genetically distinct and geographically isolated stock. [ 26 ] The population fell to 278 in 2005 and it is listed as critically endangered in the IUCN Red List of Threatened Species. [ 27 ]
When it reached the nearest tide gauge, located 140 kilometers (87 miles) [1] to the southeast of the landslide near Yakutat, Alaska, the wave had diminished to a height of 15 centimeters (5.9 inches). [1] The Taan Fiord event bore a strong similarity to the July 1958 landslide and megatsunami in Alaska's Lituya Bay. [7]
The current sets southward during the falling tide and northward during the rising tide, which is the longer and stronger of the two. Its velocity varies, but in Unalga Pass, where it is greatest, it has been found to be 61 knots an hour during the whole of the tide, and the current turned to the opposite direction at the same velocity in ...
The Port of Alaska [4] (POA) is a deep-water port in Anchorage, Alaska, with three bulk carrier berths, two petroleum berths, and one barge berth. The name was changed from "Port of Anchorage" to the "Port of Alaska" in 2017. [4] It is an enterprise department of the Municipality of Anchorage.
It is an extensive flat of bluish yellow mud, covered with water during stormy days at flood tide; but at low tide no water is present. From Point Whitshed to the southward and eastward, there is a long line of piled ice, with dwarf trees marking the channel of Eyak River, extending out into the flats. [1]
Upper reaches of Bristol Bay experience some of the highest tides in the world. One such reach, the Nushagak Bay near Dillingham and another near Naknek in Kvichak Bay have tidal extremes in excess of 10 m (30 ft), ranking them — and the area — as eighth highest in the world. Coupled with the extreme number of shoals, sandbars, and shallows ...
