title: NOAA/WDS Paleoclimatology - Shopov et al. 1996 Cold Water Cave, Iowa Speleothem Luminescence Data

description: Calcite speleothems luminescence (Shopov 1987, Shopov et al. 1994) depends exponentially upon soil temperatures that are determined primarily by solar infrared radiation in the case when that cave is covered only by  grass or upon air temperatures in case that cave is covered by forest or bush.  In the first case, microzonality of luminescence of speleothems can be used as an indirect Solar Insolation (SI) index, but in the second - as an paleotemperature proxy. So, in dependence on the cave site we may speak about ""solar sensitive"" and ""temperature sensitive"" luminescent speleothem records like in treering records, but in our case record may depend either only on temperature or on solar irradiation: - In case of Cold Water Cave (CWC), Iowa, US we obtained high correlation coefficient of 0.9 between the luminescence record and Solar Luminosity Sunspot index (Fig.1) and reconstructed sunspot numbers since 1000 AD with precision within the experimental error of their measurements; - in case of Rats Nest cave (RNC), Alberta, Canada we measured correlation coefficient of 0.67 between luminescence intensity and air temperatures record for the last 100 years (Fig.2) and reconstructed annual air temperatures for last 1500 years at the cave site with estimated error of 0.35 C, while the error of the direct measurements is 0.1 C.  Intensity of luminescence was not dependent on actual precipitations and sunspot numbers (zero correlation).  Speleothem growth rate variations represent mainly rainfall variations. Speleothem luminescence visualizes annual microbanding we used to derive proxy records of annual precipitations or the cave site.  In case of RNC we reconstructed annual precipitations for last 280 years at the cave site with estimated error of 80  mm/year.  By comparison of luminescent records with other solar proxy records we obtained a reconstruction of growth rates and precipitations in Bosnek karst region near Duhlata cave (DC), Bulgaria for the last 50000 years, and for the last 6400 years (with averaged time step of 41 years) for Iowa, near CWC. Achieved time step of 6 hours (Fig.3) in speleothem luminescence records allows resolution of several days in some best speleothem samples. Annual luminescence microbanding was used very successfully for relative and absolute dating of speleothems by Autocalibradion dating (Shopov et al. 1991). This dating method appear to be more precise than TAMS 14C and AMS U/Th dating for relative dating of short time intervals and only dating method for speleothems with little uranium, younger than 2000 years.  It is demonstrated, that speleothems can be used as natural climatic stations with annual resolution for purposes of climatology and agrometeorology for a time span far exceeding all historic records.

title: NOAA/WDS Paleoclimatology - Glacial Lake Hitchcock Varve Thickness Data

description: A glacial varve chronology from New England spanning the 4000-year period from 17,500 to 13,500 calendar years before the present was analyzed for evidence of climate variability during the late Pleistocene. The chronology shows a distinct interannual (3 to 5 years) band of enhanced variability suggestive of El Niņo-Southern Oscillation (ENSO) teleconnections into North America during the late Pleistocene, when the Laurentide ice sheet was near its maximum extent and climatic boundary conditions were different than those of today. This interannual variability largely disappears by the young end of the 4000-year chronology, with only the highest frequency components (roughly 3-year period) persisting. This record provides evidence of ENSO-like climate variability during near-peak glacial conditions.
description: The 4022 year continuous annual chronology is roughly dated between 17.5 and 13.5 kyr before present, in calibrated radiocarbon years.

title: NOAA/WDS Paleoclimatology - Tasmanian Gateway ODP Leg 189 Sediment Data and SST Reconstructions

description: The Tasmanian Gateway, focus of ODP Leg 189, is a key oceanographic area within the Southern Ocean.  Our investigations concentrate on the last ~500,000 years of sedimentation at Sites 1168 (western Tasmanian margin), 1170 and 1171 (Tasman Rise), and 1172 (East Tasman Plateau).  A suite of geochemical proxy reflecting paleo-export production, terrigenous flux, and sea surface temperature, constrain temporal and spatial variations in surface water masses and oceanographic frontal systems over these sites.  Interglacial periods were commonly of low productivity and less affected by terrigenous matter supply, suggesting that the position of the Subtropical Convergence remained south of Tasman Rise.  Only during MIS11and MIS9 over the southern Tasman Rise, and during MIS7 over the northern Tasman Rise, did enhanced marine productivity, combined with an enhanced terrigenous flux, indicate waxing influence of subantarctic waters.  During glacial MIS2, marine productivity and terrigenous flux increased significantly at sites 1168, 1170, and 1171 implying that the Subtropical Convergence moved northward to ~42S west of Tasmania.  East of Tasmania, the presence of the East Australian Current caused the Subtropical Convergence to remain south of East Tasman Plateau.  Glacial MIS6 appears to have been different from MIS2.  The Subtropical Convergence stayed north of East Tasman Plateau, but clearly south of Site 1168 on the western Tasmanian margin.  Strongly enhanced marine productivity and terrigenous flux during MIS10 and MIS12 at Sites 1168, 1170, and 1172 suggest the dominant influence of subantarctic waters and the position of the Subtropical Convergence north of the East Tasman Plateau.  At South Tasman Rise, in contrast, the reduced terrigenous flux implies that Site 1171 moved outside the belt of westerly winds.  Marine productivity ceased at that time mainly due to iron limitation.

title: NOAA/WDS Paleoclimatology - Northeastern Fennoscandia 2,000 Year Pollen Data and Inferred Summer Temperature

description: Quantitative reconstructions of mean July temperatures (T (jul)) based on new and previously published pollen-stratigraphical data covering the last 2000 years from 11 lakes in northern Fennoscandia and the Kola Peninsula are presented. T (jul) values are based on a previously published pollen-climate transfer function for the region with a root-mean-square error of prediction (RMSEP) of 0.99A degrees C. The most obvious trend in the inferred temperatures from all sites is the general decrease in T (jul) during the last 2000 years. Pollen-inferred T (jul) values on average 0.18 +/- 0.56 degrees C (n = 91) higher than present (where "present" refers to the last three decades based on pollen-inferred T (jul) in core-top samples) are indicated between 0 and 1100 AD (2000-850 cal year BP), and temperatures -0.2 +/- 0.47 degrees C (n = 78) below present are inferred between 1100 and 1900 AD (850-50 cal year BP). No consistent temperature peak is observed during the 'Medieval Warm Period', ca. 900-1200 AD (1100-750 cal year BP), but the cooler period between 1100 and 1900 AD (850-50 cal year BP) corresponds in general with the 'Little Ice Age' (LIA). Consistently with independent stable isotopic data, the composite pollen-based record suggests that the coldest periods of the LIA date to 1500-1600 AD (450-350 cal year BP) and 1800-1850 AD (150-100 cal year BP). An abrupt warming occurred at about 1900 AD and the twentieth century is the warmest century since about 1000 AD (950 cal year BP).

title: NOAA/WDS Paleoclimatology - Wertz - Riverside Park - QUMA - ITRDB ND008

description: Estimates of future flood risks are based on the observations of past floods, but instrumental records of basin hydrology are often too short to assess potential changes in the frequency or magnitude of extreme floods over time. In this study, we show that bur oak (Quercus macrocarpa Michx.) growing along the Red River of the North in North Dakota and Minnesota preserve evidence of past floods within their annual growth rings. Rings formed during major floods often displayed (i) marked reductions in the size of their earlywood vessels or (ii) a more diffuse distribution of vessels throughout the increment. Because of the correspondence between major floods and widespread anatomical anomalies within riparian oaks, we suggest that these features can be described as "flood rings." The frequency of flood-ring formation varied substantially along the river, which implies that this evidence can only provide an accurate estimate of flood history when it is obtained from many trees sampled across a dense network of sites. The rate of flood-ring formation is primarily influenced by flood magnitude but is also controlled by the timing and duration of inundation relative to the period of cambial growth. Although flood-affected oaks are imperfect recorders of past floods, this approach offers significant potential as a means to estimate the preinstrumental flood history of the Red River within the United States.

title: NOAA/WDS Paleoclimatology - Eastern Indian Ocean ODP762 Eocene Calcareous Nannofossil Data

description: A relatively complete section of Eocene (~33.9-55.8 Ma) pelagic chalk from offshore northwestern Australia was used to analyze range and abundance data of ~250 Eocene species to test the efficacy of the existing CP (Okada and Bukry 1980) and NP (Martini 1971) biostratigraphic zonation schemes. Changes in nannofossil diversity, abundance, and community structure were monitored through several Eocene paleoenvironmental events, as identified by changes in d13C and d18O data, to examine variations in surface water conditions. Major changes in nannofossil assemblages, as indicated by dominance crossovers, correspond to paleoenvironmental shifts such as the PETM (Paleocene-Eocene thermal maximum) and the EECO (Early Eocene climatic optimum). This research also provides systematic paleontology and range data for one new genus (Hexadelus) and eight new species or variants (Calcidiscus ellipticus, Cruciplacolithus nebulosus, Cruciplacolithus opacus, Cyclicargolithus parvus, Hexadelus archus, Hayella situliformis var. ovata, Markalius latus, Pedinocyclus annulus) and addresses several taxonomic issues in other Eocene species.
description: Raw Eocene calcareous nannofossil abundance data from ODP Leg 122, 
Site 762, Eastern Indian Ocean. Data are raw nannofossil counts from 
184.49-422.00 msbf (Core 3-4-49cm to 29-1-50cm). Assemblage data 
was collected by first identifying 500 specimens to species level, 
except members of Pontosphaeraceae and Syracosphaeraceae, 
which were rare and sporadic through the section. Additionally, 
two long traverses were examined to identify rare specimens, 
which were given a value of 1 and added to the total. 
This data was used to convert all species and genera to percent 
abundance for further analysis. 

Detailed site information can be found in Shamrock and Watkins (2012), 
or from Leg 122 Initial Reports (Haq et al. 1990) and Scientific Results 
(Rad et al. 1992). The vast majority of original taxonomic references 
can be found in Perch-Nielsen (1985) and Bown (1998). 
Samples were supplied by the International Ocean Drilling Program (IODP).

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
