title: NOAA/WDS Paleoclimatology - Bay of Plenty Foraminiferal Data and SST Reconstruction from 16KyrBP to Present

description: We present sea surface temperature (SST) records with centennial-scale resolution from the Bay of Plenty, north of New Zealand. Foraminiferal assemblage-based paleo-SST estimates provide a deglacial record of SST since 16.5 14C ka. Average Holocene SSTs are 15.6°C for winter and 20.3°C for summer, whereas average glacial values were 14.2°C for winter and 19.5°C for summer. Compared to modern time, cooling of SSTs at the Last Glacial Maximum (LGM) was ~0.9°C in winter and ~1.5°C in summer. The shift from glacial to Holocene temperatures began at 14.25 14C ka, warming by ~2°C until 12.85 14C ka when temperatures dipped back to glacial values at 11.65 14C ka. The timing of this return to glacial-like SST correlates well with the Antarctic Cold Reversal (ACR) rather than the Younger Dryas and documents that the influence of the ACR extended into the subtropics of the Southern Hemisphere, at least in this region of the southwest Pacific. By 10.55 14C ka an SST maximum in summer SSTs of up to 3°C warmer than modern occurred (~24°C), after which SST dropped, remaining at present-day temperatures since 9.3 14C ka. This early Holocene climatic optimum has been widely noted in the Southern Ocean, and this record indicates that this phenomenon also extended into the subtropics to the north of New Zealand.

title: NOAA/WDS Paleoclimatology - GISP2 Ice Core 1000 Year Ar-N2 Isotope Temperature Reconstruction

description: Future Greenland temperature evolution will affect melting of the ice sheet and associated global sea-level change. Therefore, understanding Greenland temperature variability and its relation to global trends is critical. Here, we reconstruct the last 1,000 years of central Greenland surface temperature from isotopes of N2 and Ar in air bubbles in an ice core. This technique provides constraints on decadal to centennial temperature fluctuations. We found that northern hemisphere temperature and Greenland temperature changed synchronously at periods of ~20 years and 40-100 years. This quasi-periodic multi-decadal temperature fluctuation persisted throughout the last millennium, and is likely to continue into the future.
description: Nitrogen and Argon isotope data from air bubbles in the GISP2 
ice core, and 1000 year temperature reconstruction based on 
the gas isotope data.  Nitrogen (15N/14N) and argon (40Ar/36Ar) 
isotopic ratios were measured, and a firn air separation model 
was used to reconstruct decadally averaged surface temperature. 
The thickness of the firn layer and the temperature gradient 
between the top and bottom of the firn layer causes known amounts 
of isotopic separation by gravitational and thermal fractionation, 
respectively (Severinghaus et al. 1998).  Measurements of two 
isotopic ratios with differing sensitivity (d15N and d40Ar) allow 
separation of the two effects, providing the past firn thickness 
and temperature gradient DT (Kobashi et al. 2007, 2008a, b; 
Severinghaus and Brook 1999). Surface temperature can be calculated 
from the DT and accumulation rate data (Kobashi et al. 2008a), 
combined with a firn-densification/heat diffusion model.

title: NOAA/WDS Paleoclimatology - Tripati et al. 2005 Eocene Greenhouse-Icehouse Transition Carbon Cycle Data

description: The transition from the extreme global warmth of the early Eocene ‘greenhouse’ climate ∼55 million years ago to the present glaciated state is one of the most prominent changes in Earth's climatic evolution. It is widely accepted that large ice sheets first appeared on Antarctica ∼34 million years ago, coincident with decreasing atmospheric carbon dioxide concentrations and a deepening of the calcite compensation depth in the world's oceans, and that glaciation in the Northern Hemisphere began much later, between 10 and 6 million years ago. Here we present records of sediment and foraminiferal geochemistry covering the greenhouse–icehouse climate transition. We report evidence for synchronous deepening and subsequent oscillations in the calcite compensation depth in the tropical Pacific and South Atlantic oceans from ∼42 million years ago, with a permanent deepening 34 million years ago. The most prominent variations in the calcite compensation depth coincide with changes in seawater oxygen isotope ratios of up to 1.5 per mil, suggesting a lowering of global sea level through significant storage of ice in both hemispheres by at least 100 to 125 metres. Variations in benthic carbon isotope ratios of up to ∼1.4 per mil occurred at the same time, indicating large changes in carbon cycling. We suggest that the greenhouse–icehouse transition was closely coupled to the evolution of atmospheric carbon dioxide, and that negative carbon cycle feedbacks may have prevented the permanent establishment of large ice sheets earlier than 34 million years ago.

title: NOAA/WDS Paleoclimatology - Lake Qinghai Surface Sediment Isotope and Geochemical Data

description: Multi-proxy indices on annual/decadal scales during the past 600 years were developed from the surface sediments of Lake Qinghai based on 210Pb and 137Cs geochronology. The d13Ccarb, d18Ocarb, and total carbonate content are consistent with one another in trends and their variations have been mainly ascribed to regional temperature. It is suggested that the strong evaporation contributes in modifying d18O of lake water and d13C of the dissolved inorganic carbon of the surface water, and appears to be responsible for the covariance between d13Ccarb and d18Ocarb. Photosynthesis of the aquatic plants appears to have played a significant role in determining d15N of organic matter.  The discrimination of 14N and 15N during photosynthesis may have triggered a positive linkage between temperatures and d15Norg (after removal of the stratigraphic trend).Variations of total organic carbon (TOC), C/N ratio, and d13Corg have been ascribed to local precipitation. TOC (after removal of the stratigraphic trend) is positively correlated with the C/N ratio (r = 0.45, a < 0.01), and negatively correlated with d13C of organic matter (d13Corg) (r = - 0.55, a < 0.01); while d13Corg is negatively correlated with the C/N ratio (r = - 0.48, a < 0.01). The climatic significance of these multi-proxy indices has been verified by comparing with the meteorological records and the climates inferred from tree rings in adjacent regions.
description: Stable isotope and geochemical data from near-surface sediments (upper 30 cm., ~600 yrBP) from Lake Qinghai, central China.  The indices from surface sediments of Lake Qinghai can be generally divided into two groups. One is dominated by precipitation (TOC, C/N, d13Corg); the other is dominated by 
temperature (d13Ccarb, d18Ocarb, total carbonate content).
