title: NOAA/WDS Paleoclimatology - Taiwan 748 Year March-August Precipitation Reconstruction

description: From the late 1920s to the early 21st century, meteorological observations indicate a decreasing trend of precipitation in Taiwan, an island in the low latitudes of East Asia, with global warming. However, it is still unclear whether the decreasing trend of Taiwan precipitation can be physically linked to an increase in temperature. Here, we present an annually resolved precipitation reconstruction for Taiwan for 1259-2006 AD based on tree-ring width and oxygen isotope indices, which both reflect a high sensitivity to climatic changes. Over the past 748 years both, extremely dry and wet years accounted for 2.8% of all years and Taiwan precipitation can reflect the large-scale precipitation in the low latitudes of East Asia. Before the onset of global warming, the precipitation reconstruction exhibited four other significant decreasing trends during the 1380s-1440s, 1640s-1700s, 1720s-1790s and 1790s-1860s, and each decreasing trend was accompanied by an increase in Northern Hemisphere temperature. This implies that the decreasing trends in precipitation were affected by increasing temperature. We also found that large volcanic eruptions in the low latitudes of the globe played an important role in precipitation changes by influencing the El Nino/Southern Oscillation and Asian summer monsoon. Precipitation usually decreased in the second year after large tropical volcanic eruptions. Our reconstruction is the longest annual-resolution precipitation reconstruction for the low latitudes of East Asia, and it is useful not only for understanding past hydroclimate changes but also for providing basic data to project future precipitation changes through climate modeling.

title: NOAA/WDS Paleoclimatology - Hainan Island, Northern South China Sea Coral d180 and Sr/Ca, 1853-2011 CE

description: The Pacific Decadal Oscillation (PDO) has been shown to have significant climatic and environmental impacts across the Pan-Pacific Basin; however, there are no records of PDO activity from the South China Sea (SCS), the largest marginal sea in the northwest Pacific Ocean. This study suggests that a series of geochemical profiles obtained from a modern coral in the northern SCS records annual PDO activity dating back to 1853. These geochemical data are significantly correlated with the PDO index, and their patterns of variation closely match those of the PDO index over the last century. The relationship between the PDO and coral geochemistry may be related to the influence of the PDO on rainfall on Hainan Island. Rainfall patterns influence the volume of terrestrial runoff, which, in turn, is a primary determinant of δ18O and Δδ18O values in coral; however, coral δ13C values are also influenced by the 13C Suess effect. The results indicate that Sr/Ca ratios in coral are affected by a combination of sea surface temperature and terrestrial runoff.

title: NOAA/WDS Paleoclimatology - Northwestern Indian Ocean Sr/Ca and d18O Data from 1917-2007 CE

description: Corals are important marine archives for high-resolution reconstructions of low-latitude climate variability in preinstrumental and historical periods. Herein, we present monthly-resolved records of d18O and Sr/Ca for the 20th century (1917–2007) from a Porites lutea colony from the Maldives (northwestern Indian Ocean). Previous studies of annual mean extension rates of this coral revealed a distinct dependency of coral growth on variations of sea surface temperature (SST) and hydraulic energy, driven by El Niño-Southern Oscillation (ENSO) and southwestern Indian monsoon forcing. This enables the investigation of coral d18O and Sr/Ca ratios from the Maldives as archives of historical ENSO and Indian monsoon variability. Unlike other locations in the Indian Ocean, correlation of d18O and SST is weak (r  =  -0.42; p < 0.001), suggesting interferences of SST and seawater d18O at the location. These interferences probably caused significantly weaker interannual ENSO signatures in d18O as evident in # the extension rates of our coral and in geochemical proxies measured at other sites in the northwestern Indian Ocean. Sr/Ca ratios show bias by nontemperature effects, and were not used to estimate seawater d18O and salinity. Strong decadal variability (10–14 years) in d18O, indicative of a Pacific ENSO signal, is not found in instrumental SST, and could be explained by variations in salinity. Interannual and decadal monsoon variability (6–7 yrs and 18–19 yrs), found in the extension rates, was not found in d18O, suggesting, in agreement with other studies, that geochemical coral proxy records from the northwestern Indian Ocean do not capture temporal variations of the Indian monsoon strength.

title: NOAA/WDS Paleoclimatology - EPICA Dome C 801,000 Year Ice Core Ionic Chemistry Data on AICC2012 Age Scale

description: The EPICA ice core from Dome C extends 3259 m in depth, and encompasses 800 ka of datable and sequential ice. Numerous chemical species have been measured along the length of the cores. Here we concentrate on interpreting the main low-resolution patterns of major ions. We extend the published record for non-sea-salt calcium, sea-salt sodium and non-sea-salt sulfate flux to 800 ka. The non-sea-salt calcium record confirms that terrestrial dust originating from South America closely mirrored Antarctic climate, both at orbital and millennial timescales. A major cause of the main trends is most likely climate in southern South America, which could be sensitive to subtle changes in atmospheric circulation. Sea-salt sodium also follows temperature, but with a threshold at low temperature. We re-examine the use of sodium as a sea ice proxy, concluding that it is probably reflecting extent, with high salt concentrations reflecting larger ice extents. With this interpretation, the sodium flux record indicates low ice extent operating as an amplifier in warm interglacials. Non-sea-salt sulfate flux is almost constant along the core, confirming the lack of change in marine productivity (for sulfur-producing organisms) in the areas of the Southern Ocean contributing to the flux at Dome C. For the first time we also present long records of reversible species such as nitrate and chloride, and show that the pattern of post-depositional losses described for shallower ice is maintained in older ice. It appears possible to use these concentrations to constrain snow accumulation rates in interglacial ice at this site, and the results suggest a possible correction to accumulation rates in one early interglacial. Taken together the chemistry records offer a number of constraints on the way the Earth system combined to give the major climate fluctuations of the late Quaternary period.

This is an update of data previously posted (https://www.ncdc.noaa.gov/paleo/study/2489) on earlier EDC age models and at lower resolution. Current dataset has resolution of 0.55 or 1.1 metres (where data are not missing). NOTE: Data file was revised 5 January 2022 between 1081.85 m and 1084.05 m because of a processing error that had transposed the depths of two consecutive sections of 1.1 m length. This corrected file gives the corrected depths and ages.

description: The International Tree-Ring Data Bank (ITRDB) provides public access to over 3000 tree-ring data sets collected over the past century, yet 809 of these sites have end dates between AD 1950 and 1980. These data cannot be calibrated with at least the past 30-40 years of instrumental data when used in climate reconstructions. We developed new tree-ring data sets at five sites in Maine, USA, to update earlier collections. Four of the five collections were successfully updated, with environmental changes at the fifth site limiting our success. Our results highlight the limits to tree longevity in a dynamic world and the need to increase and formalize efforts toward updating chronologies. We initiate a discussion to set forth explicit guidelines that help create consistent efforts to updating chronologies and provide a guide to beginning dendrochronologists who are particularly well suited to contribute to this area of work. The research was carried out through an introductory dendrochronology course taught at the University of Wisconsin-Platteville and offers a model to help direct the increasing availability of human resources to the rapidly growing field of dendrochronology.

description: The impacts of inland flooding caused by tropical cyclones (TCs), including loss of life, infrastructure disruption, and alteration of natural landscapes, have increased over recent decades. While these impacts are well documented, changes in TC precipitation extremes—the proximate cause of such inland flooding—have been more difficult to detect. Here, we present a latewood tree-ring–based record of seasonal (June 1 through October 15) TC precipitation sums (ΣTCP) from the region in North America that receives the most ΣTCP: coastal North and South Carolina. Our 319-y-long ΣTCP reconstruction reveals that ΣTCP extremes (≥0.95 quantile) have increased by 2 to 4 mm/decade since 1700 CE, with most of the increase occurring in the last 60 y. Consistent with the hypothesis that TCs are moving slower under anthropogenic climate change, we show that seasonal ΣTCP along the US East Coast are positively related to seasonal average TC duration and TC translation speed.
