Figure 3-6 The range of tidal and nontidal residual sea level extremes has been estimated for a global set of tide gauges. At some locations in the Pacific, high tides dictate sea level extremes (such as in the Marshall Islands), shown here as tide gauge stations with blue markers. In other locations, such as the Hawaiian Islands, a combination of high tides and nontidal factors are important, shown as green markers. In still other places, such as Guam and the Northern Mariana Islands, factors not related to tides dominate sea level extremes, represented with red markers at tide gauge stations.
