These stations observe ocean waves, tide levels, sea surface temperature and ocean current etc. in the Northwestern Pacific basin, as well as the Sea of Japan and the Sea of Okhotsk basin, and provide marine meteorological forecasts resulted from them, in cooperation with the Hydrographic and Oceanographic Department, Japan Coast Guard.
It is a typical Pacific Northwest headland, forming a high steep bluff above the ocean. At its highest point, Cape Perpetua rises to over 800 feet (244 m) above sea level. From its crest, an observer can see 70 miles (113 km) of Oregon coastline and as far as 37 miles (60 km) out to sea on a clear day. [1]
The tide gauge data are freely accessible by all, and consist predominantly of monthly-mean and annual-mean sea levels. The primary,"Revised Local Reference" data set has a continuous history of benchmark surveys for each gauge, ensuring that sea level is measured relative to a known land-based datum.
Storm surge could raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast in areas of onshore winds along the northern coast of Honduras and Guatemala, the ...
King tide is not a scientific term, nor is it used in a scientific context. The expression originated in Australia, New Zealand and other Pacific nations to describe especially high tides that occur a few times per year. It is now used in North America as well, [1] particularly in low-lying South Florida, where king tides can cause tidal flooding.
A storm surge will raise water levels by as much as 1 to 3 feet above normal tide levels in the British Virgin Islands. Near the coast, the surge will be accompanied by large and destructive waves.
The annual cycle of sea level height (or seasonal cycle or annual harmonic) describes the variation of sea level that occurs with a period of one year. Historically, analysis of the annual cycle has been limited by locations with tide gauge records, i.e., coastlines and some islands in the deep ocean, and by sparse records in the Southern Hemisphere.
Storm surge could also raise water levels by as much as three feet above normal tide levels along the northern coast of Honduras and the same amount above ground level near and to the north of ...
