“…Gross (1967, 1970) and Gross, Milliman, Tracey, and Ladd (1969) concluded that the crustose coralline algae had been the most abundant carbonate building elements in the limestone cap, a situation comparable to that reported for the Recent (Littler, 1971b). At about the same time, a series of borings of a Holocene "algal ridge" and its associated reef flat were begun at the other end of the Hawaiian Archipelago on Hanauma Reef in Oahu (Easton and Olson, 1973). This reef is at present strongly dominated by coralline algae, a condition that seems to have existed during much of the latter half of its 7000-year history.…”

“…On Oahu, Hawaii, fringing reefs are present. During the mid-to-late Holocene, vertical accretion rates of Hawaiian reefs were about 3 mm/yr (Easton and Olson, 1976). Given the model of Neumann and MacIntyre (1985), fossil reefs on Oahu may provide a fairly complete record of the Last Interglacial high sea stand.…”

“…Thus, the oldest Holocene Acropora palmata (a ''keepup'' species) on fringing reefs off Panama and St. Croix date to around 5000-7000 radiocarbon yr BP. Studies of a Holocene reef on Oahu show that reef growth also began about 7000 radiocarbon yr ago, and was characterized by its most rapid vertical accretion from about 5800-3500 radiocarbon yr ago (Easton and Olson, 1976). The period of rapid vertical accretion was followed by a period of seaward accretion (since 3000 radiocarbon yr ago).…”

The timing and duration of the Last Interglacial period have been controversial, with some studies suggesting a relatively short duration that is orbitally forced and others suggesting a long duration that is at most only partly related to orbital forcing. New, high-precison thermal ionization mass spectrometric (TIMS) U-series ages of Last Interglacial corals from Hawaii and Bermuda test these competing hypotheses. Waimanalo Formation corals from slowly uplifting Oahu, Hawaii range in age from B134 to B113 ka, with most ages between B125 and B115 ka. Combined with published U-series ages from nearby Lanai, the data suggest a long Last Interglacial period that may have occurred from B136 to at least 115 ka. The results indicate that orbital forcing may not have been the only control on ice sheet growth and decay, because sea level would have been high at times of relatively low Northern Hemisphere summer insolation. On tectonically stable Bermuda, deposits from the B200 ka (penultimate interglacial period), B120 ka (peak Last Interglacial period) and B80 ka (late Last Interglacial period) high sea stands have been newly dated. Fossil corals on Bermuda are derived from patch reefs that likely were ''catch-up'' responses to sea level rise. It is expected that U-series ages of Last-Interglacial corals on Bermuda should overlap with, but not be as old as the range of corals on Oahu. Last-Interglacial corals on Bermuda give a range of B125-113 ka, which supports this hypothesis.A large number of emergent marine deposits on Hawaii, Bermuda and along coastal North America have now been dated to the Last Interglacial period. Both Oahu and Bermuda have marine invertebrate faunas with a number of extralimital southern species of mollusks, suggesting warmer-than-present waters during the Last Interglacial period. Warmer waters are also suggested for LastInterglacial localities around most of North America, from Florida to Canada and Greenland and Baja California to Alaska. These observations are consistent with similar warm-water faunas of Last-Interglacial age reported from Japan, the Mediterranean basin and Western Australia. It is likely that significant changes in ocean currents took place during the Last Interglacial period, with a movement of relatively warm waters to higher latitudes than is the case today. r

“…Easton and Olson (1976) The above two studies suggest likely scenarios to describe coral reef accretion in low to moderate wave energy environments in the NWHI. Rates of coral colony growth reported by Siciliano (2005) indicate that the more northerly latitudes would not preclude similar results in lagoonal environments.…”

“…Even this limited growth is episodically removed by large swell and storms. In more sheltered areas however, such as Hanauma Bay and Kailua Bay, 10-15 m thick sequences of Holocene coral reef have accreted (Easton and Olson 1976;Grossman and Fletcher 2004). We suspect that accretion of corals and coralline algae on most fore reef environments in the NWHI is ephemeral and periodically removed by high wave events.…”
