  • Revisiting late Holocene sea-level change from the Gilbert Islands, Kiribati, west-central Pacific Ocean

    Open AccessHiroya Yamano, Hajime Kayanne et al.ARTICLEQuaternary Research2017

    New coral microatoll data allow presenting an updated late Holocene sea-level curve for the Gilbert Islands of Kiribati. Examination of build-up elevation and spatial distribution of microatolls, along with radiocarbon age data from coral samples, suggest an approximately 1 m sea-level high stand, possibly lasting from ~3500 to 1900 cal yr BP. Our sea-level curve, which is similar to the one reported from the Marshall Islands, is a baseline to re…

  • Anthropogenic impacts on water quality of the lagoonal coast of Fongafale Islet, Funafuti Atoll, Tuvalu

    Open AccessMasafumi Fujita, Jumpei Suzuki et al.ARTICLESustainability Science2013

    Water pollution, evident by negative values of redox potential in waters, occurs at the lagoonal coast located near the densely populated area of Fongafale Islet on Funafuti Atoll, Tuvalu, Central Pacific. Sediment microbial quinone analysis revealed that these coastal sediments exhibit 2.7–10.4 times more microbial biomass, significantly different microbial community structure and low microbial diversity, when compared to an undisturbed natural …

  • Intensified mid-Holocene Asian monsoon recorded in corals from Kikai Island, subtropical northwestern Pacific

    Open AccessMaki Morimoto, Hajime Kayanne et al.ARTICLEQuaternary Research2007

    Coupled records of Sr/Ca and oxygen isotope ratios (δ 18 O) of coral skeletons have been used to produce quantitative estimates of paleo-sea surface temperature (SST) and δ 18 O of surface seawater that can in some cases be converted to sea surface salinity (SSS). Two fossil corals from Kikai Island in the subtropical northwestern Pacific, a location affected by East Asian summer and winter monsoons, were analyzed to investigate differences betwe…

  • Seasonal Radiocarbon Variation of Surface Seawater Recorded in A Coral from Kikai Island, Subtropical Northwestern Pacific

    Open AccessMaki Morimoto, Hiroyuki Kitagawa et al.ARTICLERadiocarbon2004Cited by: 5References: 14

    A coral radiocarbon (Δ 14 C) investigation with a high time-resolution is crucial for reconstructing secular and seasonal Δ 14 C changes in the surface seawater which potentially reflect ocean circulations and dynamic ocean-atmosphere interactions. The Δ 14 C values of a modern coral ( Porites sp.) from Kikai Island, southern Japan, in the subtropical northwestern Pacific, were determined for the period of 1991-1998 at a monthly resolution. A cor…

  • Late Holocene Sea-Level Change on Rota and Guam, Mariana Islands, and Its Constraint on Geophysical Predictions

    Open AccessHajime Kayanne, Teruaki Ishii et al.ARTICLEQuaternary Research1993

    Holocene emergent reefs and notches are well distributed on Rota and Guam. Relative sea-level changes at these islands are reconstructed based on geomorphological observations and borings on present and emergent reefs, together with 54 radiocarbon dates. Sea level rose gradually to a maximum of 1.8 m between 6000 and 4200 yr B.P. and reached its highest level by 4200 yr B.P. on both islands. After 3200 yr B.P. abrupt uplift caused emergence of th…

  • Evidence for a Holocene High Sea-Level Stand, Vanua Levu, Fiji

    Open AccessTakao MIYATA, Yasuo Maeda et al.ARTICLEQuaternary Research1990

    Two distinct elevations of emerged notches can be recognized on the southeastern coast of Vanua Levu: the higher notch is +2.22 to +3.30 m above low-tide level and the lower +1.52 to +1.65 m above low-tide level. Many emerged Holocene corals encrust higher notch floors and benches or occur as microatolls and from these radiocarbon ages ranging from 6000 to 3400 yr B.P. were obtained. The higher notches are significantly higher than present high-t…
