“…Estimates using coral terraces and other indicators certainly suggest that sea level was higher than today in MIS 5e [ Kopp et al , ; Dutton and Lambeck , ]. Some less direct evidence suggests the same for MIS 11 [ Raymo and Mitrovica , ], although there continues to be more debate about sea level in this earlier interglacial [e.g., Hearty et al , ; Olson and Hearty , ; Bowen , ; Raymo and Mitrovica , ]. One way to explain particularly low ice volume/high sea level during interglacials would be through melting of all or part of the Greenland ice sheet.…”

Interglacials, including the present (Holocene) period, are warm, low land ice extent (high sea level), end-members of glacial cycles. Based on a sea level definition, we identify eleven interglacials in the last 800,000 years, a result that is robust to alternative definitions. Data compilations suggest that despite spatial heterogeneity, Marine Isotope Stages (MIS) 5e (last interglacial) and 11c (~400 ka ago) were globally strong (warm), while MIS 13a (~500 ka ago) was cool at many locations. A step change in strength of interglacials at 450 ka is apparent only in atmospheric CO 2 and in Antarctic and deep ocean temperature. The onset of an interglacial (glacial termination) seems to require a reducing precession parameter (increasing Northern Hemisphere summer insolation), but this condition alone is insufficient. Terminations involve rapid, nonlinear, reactions of ice volume, CO 2 , and temperature to external astronomical forcing. The precise timing of events may be modulated by millennial-scale climate change that can lead to a contrasting timing of maximum interglacial intensity in each hemisphere. A variety of temporal trends is observed, such that maxima in the main records are observed either early or late in different interglacials. The end of an interglacial (glacial inception) is a slower process involving a global sequence of changes. Interglacials have been typically 10-30 ka long. The combination of minimal reduction in northern summer insolation over the next few orbital cycles, owing to low eccentricity, and high atmospheric greenhouse gas concentrations implies that the next glacial inception is many tens of millennia in the future. Introduction-Interglacials of the Last 800 kaEarth's climate of the last 800 ka (1 ka = 1000 years) is the latest stage in a slow cooling that has been in progress for the last~50 Ma (1 Ma = 1 million years) [Zachos et al., 2008]. During this cooling, ice sheets formed on the Antarctic continent~40 Ma ago, while the first signs of Northern Hemisphere (NH) glaciation appeared much more recently. Only at the start of the Quaternary Period and the Pleistocene Epoch,~2.6 Ma ago, did alternations between cold glacial periods with ice on the NH continents, and warmer intervals with little or no NH continental ice, first appear, reflected in the appearance of ice-rafted debris Kleiven et al., 2002] and in enhanced amplitude of cyclicity in benthic oxygen isotopes in marine sediment records (Figure 1) [Lisiecki and Raymo, 2005].Somewhere between 1.2 and 0.6 Ma ago, weaker cycles with a period of~40 ka gave way to stronger (greater isotopic amplitude) cycles with a recurrence period closer to 100 ka. This change is known as the Mid-Pleistocene Transition or Revolution. Its exact date is debated, and it is likely that different aspects of climate shifted into their new mode of operation at different times [Mudelsee and Schulz, 1997;Rutherford and D'Hondt, 2000;Clark et al., 2006;Elderfield et al., 2012]. By 800 ka ago, the change in amplitude was complete in most re...

“…MIS 11 is in fact considered the first strong interglacial through the MB. It also represents the longest-lasting warm period of the last 1.0 Ma (McManus et al, 1999;Hodell et al, 2000;Jouzel et al, 2007;Rodrigues et al, 2011;Milker et al, 2013), during which the sea level has been suggested to be up to 20 m above the current level (Hearty et al, 1999;Kindler and Hearty, 2000) or close to the Holocene high-stand (Rohling et al, 2009;Bowen, 2010). MIS 11 follows the largest amplitude transition (Termination V) of the last 500 kyr (Oppo et al, 1998;Rodrigues et al, 2011), at the end of MIS 12 known to be the strongest glacial of the last 800 kyr (Lang and Wolff, 2011).…”

“…Morphologic evidence of late Cenozoic sea-level changes mostly documents Middle and Upper Pleistocene times (Guilcher, 1969;Johnson and Libbey, 1997;Siddal et al, 2006;Bowen, 2010;Pedoja et al, 2011Pedoja et al, , 2014Murray-Wallace and Woodroffe, 2014;Rovere et al, 2016). In fact, little is known about interglacials older than Marine Isotopic Stage 11 (MIS 11,360e420 ka); their timing, duration and number of high-stands would have remained unknown if isotope records were not partly alleviating our lack of knowledge (Emiliani, 1955;Shackleton, 1987;Waelbroeck et al, 2002;Lisiecki and Raymo, 2005;Bintanja and Van de Wal, 2008;Zachos et al, 2008;Rohling et al, 2009).…”

Many islands of the eastern Indonesian Archipelago exhibit Late Cenozoic sequences of coral reef terraces. In SE Sulawesi, on the Tukang Besi and Buton archipelagos, we identified 23 islands bearing such sequences. Remote sensing imagery and field mapping combined to U/Th and 14 C dating enable to establish a chronologic framework of the reef terrace sequences from Wangi-Wangi, Buton as well as on the neighbouring, smaller islands of Ular, Siumpu and Kadatua. We identified the terraces from the last interglacial maximum (MIS 5e) at elevations lower than 20 m except on W Kadatua where it is raised at 34 ± 5 m. Such elevations yield low to moderate Upper Pleistocene uplift rates (<0.3 mm yr À1). On SE Buton Island, a sequence culminates at 650 m and includes at least 40 undated strandlines. Next to this exceptional sequence, on the Sampolawa Peninsula, 18 strandlines culminate at 430 m. Dated samples at the base of this sequence (<40 m) yield mean Middle Pleistocene uplift rates of 0.14 ± 0.09 mm yr À1. Extrapolation of these uplift rates compared to the geological setting suggests that the sequences of the Sampolawa Peninsula provide a record of sea-level high-stands for the last 3.8 ± 0.6 Ma. The sequences on SE Buton Island therefore constitute the best preserved long-lasting geomorphic record of Plio-Quaternary sea-level stands worldwide.
