Book excerpt: Excerpt from Alaska Coast Pilot Notes on the Fox Islands Passes, Unalaska Bay, Bering Sea, and Arctic Ocean Tide tables for the Pacific Coast of the United States, including British Columbia and Alaska, are published annually by the Coast and Geodetic Survey, predicting the times and heights of tides for every day in the year. On the coast of Alaska, including Bering Sea and the Arctic Ocean, there are usually two unequal high waters and two unequal low waters during the lunar day, the irregularity varying principally with the declination of the moon. When the moon is near the equator the tides are generally nearly equal and have the least diurnal range. When the moon is near its greatest declination (farthest north or south) the tides are very unequal, and are called tropic tides. At such times the difference between the higher high and lower low water is the great tropic range, which is usually the greatest range for the month. In Norton Sound the tides are chiefly diurnal, from the fact that the inequality in the tides when the moon is near its greatest declination is increased to such an extent that the minor tides of the day (lower high water and higher low water) disappear, and but one high water and one low water occur during the lunar day. When the moon is near the equator, however, there are generally two high waters and two low waters, more or less unequal, during the lunar day, but the range of the tides is comparatively small.
