title: NOAA/WDS Paleoclimatology - Liang Luar Geochemical Data from 90900 to 79200 Cal Yr BP

description: Dansgaard–Oeschger (D–O) cycles were the most prominent, abrupt climate events of the last glacial period whose impact was most strongly felt in the high latitudes of the North Atlantic region. The climate links between the North Atlantic, the Asian and American tropics, and Antarctica during these cycles are well documented. However, the potential role of the Indo-Pacific Warm Pool and Australasian monsoon system in propagating climate impacts across the hemispheres is still unclear. Here, we use tandem measurements of oxygen isotopes in calcite and fluid inclusions, as well as carbon-isotope ratios, from multiple stalagmites from Liang Luar Cave, Flores (southern Indonesia) to examine the monsoon response to D–O event number 21 (~87,000–84,000 years ago), the longest and warmest event recorded in Greenland ice cores. The record shows that there was a rapid decline in monsoon rainfall in Indonesia during D–O21 warming in Greenland and cooling in Antarctica. At around the same time, the East Asian monsoon was intensified, indicating that the intertropical convergence zone (ITCZ) shifted abruptly to the north during this event. Our record also shows that there was a 2–3 °C increase in local air temperature, which would have acted to increase primary productivity and promote the generation of soil carbon for methanogenesis. Therefore, our findings indicate that ITCZ positioning in tropical Australasia—through its influence on large-scale oceanic–atmospheric circulation—played a key role in transmitting the abrupt climate signal between the hemispheres, thereby facilitating the rapid rise of atmospheric CO2 and CH4 concentrations during D–O21 that ultimately led to global warming and the demise of the MIS5b stadial.

title: NOAA/WDS Paleoclimatology - Valmiki Cave Geochemical Data from 15700 to 14700 Cal Yr BP

description: A high resolution record of the Indian summer monsoon (ISM) is generated using a δ18O time series from a stalagmite collected from the Valmiki cave in southern India. This record covers a time span of ~ 1000 years from 15,700 to 14,700 yr BP (before 1950 AD) with an average sampling resolution of ~ 5 years. High amplitude δ18O variation in this record reflects abrupt changes in ISM activity during the last deglaciation and suggest an age for the onset of Termination 1a (T1a) at ~ 14,800 yr BP in the Indian sub-continent. This record shows evidence for strong changes in tropical climate during the last deglaciation. Coincident variability in VSPM4 δ18O with speleothems from southern China during Termination 1a suggests that these caves reflect fluctuations in ISM activity. The variance in δ18O amplitude reveals significant multidecadal variability in ISM activity. Our record reveals intervals of strong monsoon activity during the later phase of Heinrich event 1 (H1) and shows synchronous multidecadal variability between ISM and East Asian monsoon (EAM). Spectral analysis of δ18O time series in VSPM4 reveals solar forcing and strong ocean–atmospheric circulation control on ISM dynamics during the studied time interval.

title: NOAA/WDS Paleoclimatology - Farris fire data from Mica Mountain - IMPD US03_MCA

description: Fire scars are used widely to reconstruct historical fire regime parameters in forests around the world. Because fire scars provide incomplete records of past fire occurrence at discrete points in space, inferences must be made to reconstruct fire frequency and extent across landscapes using spatial networks of fire-scar samples. Assessing the relative accuracy of fire-scar fire history reconstructions has been hampered due to a lack of empirical comparisons with independent fire history data sources. We carried out such a comparison in a 2780-ha ponderosa pine forest on Mica Mountain in southern Arizona (USA) for the time period 1937–2000. Using documentary records of fire perimeter maps and ignition locations, we compared reconstructions of key spatial and temporal fire regime parameters developed from documentary fire maps and independently collected fire-scar data (n = 60 plots). We found that fire-scar data provided spatially representative and complete inventories of all major fire years (>100 ha) in the study area but failed to detect most small fires. There was a strong linear relationship between the percentage of samples recording fire scars in a given year (i.e., fire-scar synchrony) and total area burned for that year (y = 0.0003x + 0.0087, r2 = 0.96). There was also strong spatial coherence between cumulative fire frequency maps interpolated from fire-scar data and ground-mapped fire perimeters. Widely reported fire frequency summary statistics varied little between fire history data sets: fire-scar natural fire rotations (NFR) differed by <3 yr from documentary records (29.6 yr); mean fire return intervals (MFI) for large-fire years (i.e., ≥25% of study area burned) were identical between data sets (25.5 yr); fire-scar MFIs for all fire years differed by 1.2 yr from documentary records. The known seasonal timing of past fires based on documentary records was furthermore reconstructed accurately by observing intra-annual ring position of fire scars and using knowledge of tree-ring growth phenology in the Southwest. Our results demonstrate clearly that representative landscape-scale fire histories can be reconstructed accurately from spatially distributed fire-scar samples.

title: NOAA/WDS Paleoclimatology - Chalet Caribe Reef - Radiocarbon Data

description: Measurements of bomb-produced radiocarbon and 210Pb provide concordant estimates of the growth rate of the sclerosponge Ceratoporella nicholsoni collected from the reef slope of northern Jamaica. Radiocarbon measurements of older growth bands in the same specimen are similar to the time history of radiocarbon in coral bands from two sites in the northwestern Atlantic. Furthermore, 210Pb and stable Pb analyses reveal that the sclerosponge incorporates this element at much higher concentrations than corals.

title: NOAA/WDS Paleoclimatology - Minami Daito Island, Okinawa, Japan Isotope and Temperature Data of Cave Deposits from the Mid-Holocene

description: The impact of volcanic and solar forcings on multi-decadal climate change during the Holocene remains unclear. Here, we analysed the stable isotopes of fluid inclusions in a stalagmite to investigate hydroclimate responses to the forcings in the Northwest Pacific region. Our stalagmite data, covering the active volcanism period in the mid-Holocene, showed that the start of large volcanic eruption clusters tends to coincide with an onset or an ongoing cooling phase. The impact of one of the largest volcanic eruptions during the Holocene, likely at Kikai caldera, is recorded as an amplified multi-decadal scale variation, including a noticeable cold-wet climate anomaly. Excluding this anomalous period, the solar forcing record negatively correlated with stalagmite-derived precipitation but not with stalagmite-derived temperature. Our data suggest that clusters of volcanic activity during the mid-Holocene likely contribute to climate change at multi-decadal scale via a teleconnection between the Northwest Pacific and the North Atlantic regions.
