Reliability of coral isotope records from Pacific warm pool: A comparison using age-optimized records

چکیده
Stable isotope analysis of two separate corals from Nauru Island in the warm pool of the western tropical Pacific confum that coral oxygen isotopes are a robust recorder of environmental variables.Coral 0180faithfully records interannual variability even when strongly influenced by kinetic effects. Interannual to decadal variability of coral oDe remains enigmatic; only one of the two corals exhibits the expected light-oDCresponse in the interannual band. Coral 0180from this region has a great similarityto global instrumental temperature records reflecting the impact of the Pacific warm pool and variations of the Indonesian Low in concert with EI Nino-Southern Oscillation on global climate. Since 1896,coral 0180has exhibiteda cumulativedecrease of 0.7%0,which reflects a combination of warming and more frequent EI Nino events (precipitation) affecting the surface waters of this region.

متن کاملCoupled model simulations of mid-Holocene ENSO and comparisons with coral oxygen isotope records
The sensitivity of El Niño-Southern Oscillation (ENSO) to changes in mean climate is investigated for simulations of pre-industrial and mid-Holocene (6000 years before present) climate using the Hadley Centre coupled atmosphere-ocean model, HadCM3. Orbitally-forced changes in insolation in the mid-Holocene produce changes in seasonality which may alter ENSO amplitude and frequency. The model si...
متن کاملInterdecadal-Decadal Climate Variability from Multi-Coral Oxygen Isotope Records in the South Pacific Convergence Zone Region Since 1650AD
[1] In the South Pacific, interdecadal-decadal oceanic and atmospheric variability, referred to as the Interdecadal Pacific Oscillation (IPO), is most pronounced in the South Pacific Convergence Zone (SPCZ) salinity front region. Here we have used annual average oxygen isotope (dO) time series from five coral cores collected from Fiji and Tonga in this region to construct a Fiji-Tonga Interdeca...
متن کاملA 170-year Sr/Ca and Ba/Ca coral record from the western Pacific warm pool: 2. A window into variability of the New Ireland Coastal Undercurrent
[1] A Porites coral from New Ireland (2.5 S, 150.5 E), at the heart of the Pacific warm pool, records variations of Ba/Ca back to the early 1820s. The New Ireland Coastal Undercurrent, which flows along the north coast and transports high-nutrient thermocline waters, is thought to be the main source of the Ba enrichment observed in the coral during El Niño. Between the 1850s and the 1960s, freq...
متن کاملNorthern Hemisphere Glaciation during the Globally Warm Early Late Pliocene
The early Late Pliocene (3.6 to ∼3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO2 concentrations were comparable to today's and global climate was warmer. Yet a severe global glaciation during marine isotope stage (MIS) M2 interrupted this phase of global warmth ∼3.30 million years ago, and is seen as a premature attempt of the climate system to estab...
