title: NOAA/WDS Paleoclimatology - Pinnacle Cave Geochemical Data from 20000 to 15600 Cal Yr BP

description: We present a new U-series dated speleothem record (PC-1) from the Great Basin that documents deglacial climate variability between ca 20.1 and 15.6 ka. Our data show an abrupt 18.6 ka cold event preceding Heinrich event 1 that is consistent with expansion of the Laurentide Ice sheet during the ‘binge’ phase of ice growth. This event coincided with dessication of pluvial Lake Mojave suggesting cold and dry conditions in the southern Great Basin at this time. PC-1 δ18O values before and during Heinrich event 1 are similar, but an increase in stalagmite growth rates suggests wetter conditions that coincided with deposition of spring deposits in southern Nevada. The time interval of our record is consistent with the timing of pluvial conditions in the Great Basin as evident from a comparison to regional wetness proxies. Our new speleothem record, recovered from the recharge area for Devils Hole, does not show a δ18O increase coincident with the abrupt increase in Devils Hole δ18O at c. 18 ka, challenging the view that the Great Basin experienced an early Termination I. This hypothesis is supported by two other southwest speleothem records that demonstrate deglaciation was synchronous with forcing from the North Atlantic Ocean. We suggest that Devils Hole speleothem δ18O values may partly reflect source water changes in the regional aquifer. Further, Devils Hole δ13C minima coincide with peak global glacial conditions and weak Asian monsoon periods, suggesting that they constrain better the timing of pluvial conditions in the Great Basin.

description: Despite efforts over recent decades, a gap persists in the global network of tree-ring chronologies in the tropical Americas and especially for low-elevation sites. This gap can be attributed to the inherent challenges in identifying tropical species well-suited for dendrochronology that form reliably annual rings. Even when seasonal growth rhythms do exist, properly distinguishing true annual boundaries from false rings and identifying any locally absent rings can make the process of visually crossdating lowland tropical species extremely challenging. Here, we combine traditional dendrochronological techniques with high-precision radiocarbon bomb-pulse dating and wood anatomical analysis to confirm annual ring formation in Cedrela odorata L and Swietenia macrophylla King (Meliaceae) in the northern Maya lowlands of Guatemala. Our findings indicate annual ring formation in both species, but the radiocarbon measurements also indicated an initial misdating due to the anatomical challenges encountered during visual and graphical crossdating. We demonstrate how the iterative use of dendrochronological, wood anatomical, and radiocarbon methods allowed us to correct, validate and assign exact calendar dates to our tree-ring series. Once the exact chronology was established, we found that tree-ring width in both species is influenced by precipitation during June, July and August, which coincides with the timing of the Midsummer Drought in the Central American precipitation regime. Successfully demonstrating annual tree growth periodicity in Cedrela odorata and Swietenia macrophylla establishes the groundwork for future tree-ring research, including climate reconstructions, as well as the potential to develop annually resolved 14C records in the lowlands of Central America.

title: NOAA/WDS Paleoclimatology - Soylegrotta Cave Geochemical Data from 4100 to -43 Cal Yr BP

description: High-precision TIMS U-series dates and continuous stable oxygen and carbon isotope profiles of a 4000 year stalagmite record from Rana, northern Norway, are presented and compared with data from two other speleothems from the same cave. The dating results yield ages from 3875±34 to 296±3 years before AD2000, with 2σ errors from 0.5 to 1%. The overall growth rate is 35 mm/ka, corresponding to a temporal resolution of 29 years/mm. The stalagmite is tested for isotopic equilibrium conditions, where all ‘Hendy’ tests, except one, indicate isotopic equilibrium or quasi equilibrium deposition. Both the stable oxygen and carbon isotope records reveal a strong and abrupt enrichment in the near-top measurements. This corresponds in time to the opening of a second cave entrance in the late 1960s, which caused changes in the cave air circulation. The stable oxygen isotope signal is enriched compared to the modern value over the last 300 years, indicating a negative response to temperature changes. Likewise, the stable carbon isotope record is enriched in this period. However, both of the stable isotope records are shown to be significantly enriched compared to the isotope ranges displayed by other stalagmites in the same cave, and this questions the reliability of the proxy records derived from the presented stalagmite. Still, a general good correspondence of large scale fluctuations is found between the three stable oxygen isotope records from this cave. The stable carbon isotope records show large variations within the cave and are believed to be governed by soil-zone conditions, percolation pathways and possibly driprates.

title: NOAA/WDS Paleoclimatology - Yonderup Cave Cave Geochemical Data from 190 to -58 Cal Yr BP

description: Speleothem records of past environmental change provide an important opportunity to explore fire frequency and intensity in the past, and the antecedent climatic conditions leading to fire events. Here, fire sensitive geochemical signals in a stalagmite from Yonderup Cave, a shallow cave in Western Australia, are compared to well-documented wildfire events that occurred in recent decades. The results are extended to identify wildfires during the growth interval of the speleothem (1760 CE–2005 CE). Principal component analysis of the stalagmite time-series revealed distinct peaks in a combination of phosphorus and metal (aluminium, zinc, copper and lead) concentrations in response to known fire events, which are interpreted to have come from ash. Varying responses in the geochemical signal in the pre- and post-European colonisation period are likely linked to changes in land management, fire frequency and fire intensities. Of note is what we infer to be a particularly intense fire event concluded to have occurred in 1897 ± 5 CE, which climate sensitive proxies (δ18O and bedrock-derived elements) indicate was preceded by a multi-decadal dry period that began in the late 1860s. The intensity of the deduced fire event is supported by a peak in P that is 6.3 times higher than elsewhere in the speleothem, accompanied by a peak in Zn. It was also inferred that changes to the surface-cave hydrology occurred as a result of this event, indicated by increased input of colloidal organic material onto the stalagmite that was interpreted to be caused by shallow karst bedrock fracturing from the heat-induced deformation that is observed after intense fires. These findings show the potential for speleothems to provide dated records of fire intensity and recurrence intervals. Further development could lead to a better understanding of the climate-fire relationship and the effects of land-management practices on wildfire frequency and intensity.

title: NOAA/WDS Paleoclimatology - Entrische Kirche Cave Geochemical Data from 126900 to 113400 Cal Yr BP

description: The transition from interglacial to glacial climate has attracted much attention in paleoclimatic research, partly because orbital forcing dictates that such a return to a new ice age is inescapable (albeit in the distant future only). The detailed series of steps that leads to glacial inceptions remains poorly understood, however, and studies of past glacial inceptions are often compromised by incomplete records, imprecise chronological control, and/or uncertainties associated with proxy-transfer functions. Here we present results from U–Th-dated speleothems from a cave in the Austrian Alps (Entrische Kirche cave) which grew continuously between ca 127 and 114 ka and intermittently also during subsequent stadials and interstadials. The alpine setting of this cave is prone to periglacial and glacial processes as well as temperature and precipitation changes which are recorded in these cave deposits. We use high-resolution stable isotope data to constrain paleoenvironmental changes associated with the demise of the Last Interglacial, unprecedented in detail for central Europe. Peak interglacial conditions are characterized by high δ18O values and high growth rates from ca 127 to 124 ka. A major drop in δ18O by 3‰ occurred at ca 118 ka, which coincided with cold event C26 in the North Atlantic. This isotopic shift, which occurred at or close to isotopic equilibrium, cannot be explained by simple uniform cooling. Modelling suggests that enhanced seasonality, dominated by significant changes in winter precipitation, are required to reconcile the isotope data with the fact that calcite deposition continued across the MIS 5e/d transition (i.e., no cave freezing). This period of enhanced seasonality lasted for several millennia during which the catchment area of the cave remained geomorphologically stable and ice free. Eventually, speleothem growth terminated at ca 114 ka, which is in line with widespread ice-rafting in the North Atlantic (cold event C24) and the onset of fully stadial conditions during MIS 5d.
