title: NOAA/WDS Paleoclimatology - Cook - Laya-1 - LAGR - ITRDB BT016

description: The Asian monsoon system affects more than half of humanity worldwide, yet the dynamical processes that govern its complex spatiotemporal variability are not sufficiently understood to model and predict its behavior, due in part to inadequate long-term climate observations. Here we present the Monsoon Asia Drought Atlas (MADA), a seasonally resolved gridded spatial reconstruction of Asian monsoon drought and pluvials over the past millennium, derived from a network of tree-ring chronologies. MADA provides the spatiotemporal details of known historic monsoon failures and reveals the occurrence, severity, and fingerprint of previously unknown monsoon megadroughts and their close linkages to large-scale patterns of tropical Indo-Pacific sea surface temperatures. MADA thus provides a long-term context for recent monsoon variability that is critically needed for climate modeling, prediction, and attribution.

title: NOAA/WDS Paleoclimatology - Sauchyn - Callum Creek-Whalebacks - PSME - ITRDB CANA334

description: In western Canada growing demand for water resources has increased vulnerability to hydrological drought. The near full allocation of water supplies in the Oldman and Bow River subbasins of the South Saskatchewan River Basin has resulted in a moratorium on new surface water licenses. In this region, short instrumental records limit the detection of long-term hydrological variability. To extend the historical record, we collected 14 new moisture-sensitive tree ring chronologies and reconstructed the average October through September flow of the Oldman (1618-2004) and South Saskatchewan (SSR) (1400-2004) rivers. Our SSR proxy record updates a previously published reconstruction. While the 20th century is representative of drought frequency over the long term, droughts are of greater severity and duration in the preinstrumental proxy record. A spectral analysis of the reconstructed flows revealed quasiperiodic cycles at interannual to multidecadal scales.

title: NOAA/WDS Paleoclimatology - Cook - Greater Albany Region historical oak - QUSP - ITRDB NY040

description: Six water emergencies have occurred since 1981 for the New York City region (NYC) despite: 1) its perhumid climate, 2) substantial conservation of water since 1979 and 3) meteorological data showing little severe or extreme drought since 1970. We reconstruct 472 years of moisture availability for the NYC watershed to place these emergencies in long-term hydroclimatic context. Using nested reconstruction techniques, 32 tree-ring chronologies comprised of 12 species account for up to 66.2% of the average May-August Palmer Drought Severity Index. Verification statistics indicate good statistical skill from 1531-2003. The use of multiple tree species, including rarely-used species that can sometimes occur on mesic sites like Liriodendron tulipifera, Betula lenta and Carya spp., seems to aid reconstruction skill. Importantly, the reconstruction captures pluvial events in the instrumental record nearly as well as drought events and is significantly correlated to precipitation over much of the northeastern US. While the mid-1960s drought is a severe drought in the context of the new reconstruction, the region experienced repeated droughts of similar intensity, but greater duration during the 16th and 17th centuries. The full record reveals a trend towards more pluvial conditions since ca 1800 that is accentuated by an unprecedented, 43-year pluvial event that continues through 2011. In the context of the current pluvial, decreasing water usage, but increasing extra-urban pressures, it appears that the water supply system for the greater NYC region could be severely stressed if the current water boom shifts towards hydroclimatic regimes like the 16th and 17th centuries.

title: NOAA/WDS Paleoclimatology - Copenheaver - Reynolds Homestead Forest Resources Research Center - QUAL - ITRDB VA028

description: A 280-year old white oak chronology was developed for south-central Virginia to verify the timber harvesting and construction dates of a cabin located on the Reynolds Homestead Research Center. A plaque on the cabin stated that the logs were harvested in 1814. However, the outer rings of the logs dated to 1875 and 1876. From the land-use history of the area, the cabin was most likely constructed to house tenant farmers after the Civil War. Most of the periods of below average growth identified in the 280-year chronology were related to drought events. Correlations between the radial growth of the white oak with temperature and precipitation data from a local weather station were examined. Precipitation had more influence on radial growth than temperature, and significant correlations (p = 0.05) existed between radial growth and precipitation from the previous September, the current April, and the current June.

title: NOAA/WDS Paleoclimatology - Great Barrier Reef 5000 Year Mollusc Amino Acid Racemization Calibration Data

description: Numerical ages derived from amino acid racemization (AAR) geochronology are typically based on calibration curves that relate the extent of AAR to the age of independently dated specimens. Here, we compare options for developing calibration curves and quantifying age uncertainties using AAR data from 481 late Holocene shells, and AMS 14C analyses of 36 shells of four molluscan taxa (Ethalia, Natica, Tellina, and Turbo) collected from shallow sediment cores from a back-reef lagoon of the central Great Barrier Reef. The four taxa differed substantially in the quality of their geochronogical results. Explicitly including data from specimens alive at the time of collection improves calibration curves, but weighting numerical ages based on their uncertainty has no effect. Calibration curve statistics do not adequately assess calibration uncertainty. The relation between ages inferred from different amino acids is recommended for identifying aberrant specimens and quantifying the uncertainty of inferred ages. For this study, the AAR ages based on two amino acids (aspartic acid and glutamic acid) exceed 200 yr or 20% of their mean inferred age in ~15% of the specimens. Once these were removed, the mean age error (1sigma) for individual specimens based on two amino acids analyzed in duplicate subsamples ranged from 53 to 142 yr for Tellina and Turbo, respectively, or about a 30% age error for these relatively young shells. This compares favorably with analytical errors estimated at 50 yr or 5%. The presence of notable outliers undetectable using data from single amino acids emphasizes the importance of analyzing multiple amino acids.

title: NOAA/WDS Paleoclimatology - Bohai Sea 135KYr Relative Sea Level Reconstruction

description: Future anthropogenic sea-level rise and its impact on coastal regions 
is an important issue facing human civilizations. Due to the short 
nature of the instrumental record of sea-level change, development 
of proxies for sea-level change prior to the advent of instrumental 
records is essential to reconstruct long-term background sea-level 
changes on local, regional and global scales. Here, we employ numerical 
methods to partition sediment grain size using a combined database 
of marine surface and core samples, and to quantitatively reconstruct 
sea-level variation since the late Pleistocene in the south Bohai Sea, 
China. Our sea-level reconstruction indicates that relative sea-level 
changes in the southern Bohai Sea track global sea-level variation 
for the duration of the record. The results also indicate substantial 
regression from 70 to 30 cal kyr BP, and potentially subarial exposure 
from 38 to 20 cal kyr BP. Our results document the feasibility of 
reconstructing relative sea-level change by numerical partitioning 
of sediment grain size data, demonstrating the potential for future 
applications.

title: NOAA/WDS Paleoclimatology - Sauchyn - Swan Hills-Swan River - PCGL - ITRDB CANA348

description: Ring-width data from 138 sites in the Canadian Prairie Provinces and adjacent regions are used to estimate summer drought severity during the past several hundred years. The network was divided into five regional groups based on geography, tree species, and length of record: the eastern Rockies, northern Saskatchewan, central Manitoba, southern Manitoba, and northwestern Ontario. Regional tree-ring records are primarily related to summer moisture and drought conditions, and are less responsive to droughts caused by deficits in winter precipitation. These summer-sensitive data are not linearly related to major modes of climate variability, including ENSO and the Pacific decadal oscillation (PDO), which primarily affect the climate of western Canada during winter. Extended drought records inferred from tree rings indicate that drought on the Canadian Prairies has exhibited considerable spatial heterogeneity over the last several centuries. For northern Saskatchewan and northwestern Ontario, intervals of persistently low tree growth during the twentieth century were just as long as or longer than low-growth intervals in the eighteenth or nineteenth centuries. Longer records from southern Alberta suggest that the most intense dry spell in that area during the last 500 yr occurred during the 1720s. At the eastern side of the prairies, the longest dry event is centered around 1700 and may coincide with low lake stands in Manitoba, Minnesota, and North Dakota. Although the Canadian Prairies were dry at times during the 1500s, there is no regional analog to the sixteenth-century "megadroughts" that affected much of the western United States and northern Mexico.

title: Wave 1 of the Longitudinal Workers Survey of Retrenched Automotive Workers
title: Stream 1 Longitudinal Workers Survey

description: This dataset presents the results of the Wave 1 of the Longitudinal Workers Survey of Retrenched Workers. Participants in our longitudinal workers survey had jobs which were earmarked for retrenchment leading up to the closure of assembly plants operated in Australia by General Motors Holden, Toyota Motor Company, and Ford. Participant contact information was passed on to the research team at the University of South Australia by the government partners of the project. Participants had provided consent for their details to be used for further communication as part of their engagement in retraining and transition services.

The study was developed to investigate the efficacy of private and public investments in pre-retrenchment counselling and training, by collecting data to help understand:

- Which factors affect decisions to exit or stay in the labour market;
- Which factors improve the chances of employment;
- Which factors shorten the spell of unemployment; and
- The intermittency of work careers and labour ‘branching’ processes.
