title: NOAA/WDS Paleoclimatology - Proctor et al. 2002 Northwest Scotland Stalagmite Data to 3600 BP

description: Annual band counting on three radiometrically dated stalagmites from NW Scotland, provides a record of growth rate variations for the last 3000 years. Over the period of instrumental meteorological records we have a good historical calibration with local climate (mean annual temperature/mean annual precipitation), regional climate (North Atlantic Oscillation) and sea surface temperature (SST; strongest at 65-70°N, 15-20°W), although the correlation with the latter breaks down prior to the instrumental record. This suggests that the climatic factors that force NW Scottish climate and therefore our stalagmite growth varied through time, and include winter NAO strength, the strength of the thermohaline circulation and possibly solar output. Spectral analysis was performed on the stalagmite growth rate time series. A spectral frequency of 50-70 years is predominant in two stalagmites that were deposited from 1000 to 3000 BP; a slightly longer frequency of 72-94 years is dominant from 1000 BP to present. These are the same as that observed in ocean GCM output for the North Atlantic region SSTs. Our stalagmites provide high resolution, precisely dated evidence of a similar periodicity predominating over the last 3000 years in a climate proxy record known to be sensitive to changes in forcing functions relevant to the North Atlantic sector.
description: Dataset name: Stalagmite SU-96-7, SU-96-1 and SU-96-2. Location: Uamh an Tartair, part of the Cnoc nan Uamh cave system, 3 km east of Inchnadamph in Assynt, Northwest Scotland, UK National Grid Reference NC 276 206. 58° 09' N, 04° 59'W, 220 m a.s.l. Additional site information: Uamh an Tartair is overlain by moorland with thin peat between 0.1 and 0.6 metre thick. This area of moorland has remained undisturbed within historical times and analysis of cores from the peat has provided a dated 2000 year record of humification and vegetation from the site (Baker et al., 1999, EPSL) and a 1000 year record of climate (Proctor et al, 2000). This dataset extend that of Proctor et al.(2000) with the addition of two further stalagmites that extend the growth rate record back to 3600 BP. Data are presented as both the annual growth rate recorded from lamina thickness, as well as a decadal smoothed value. In addition, the mean of all three stalagmites is calculated. In Proctor et al (2000) we presented a historical calibration of growth rate with climate. This could be applied to the series here using the equation: Annual band width = -206 + 68200 (T/P)  (r=0.77) where Annual band width (microns), T = mean annual temperature (°C) and P = mean annual precipitation  (mm). Note: This dataset is that used by Trouet et al (2009).

title: NOAA/WDS Paleoclimatology - Ruehlemann et al. 1999 Tropical Atlantic Alkenone SST Reconstruction

description: Evidence for abrupt climate changes on millennial and shorter timescales is widespread in marine and terrestrial climate records. Rapid reorganization of ocean circulation is considered to exert some control over these changes, as are shifts in the concentrations of atmospheric greenhouse gases. The response of the climate system to these two influences is fundamentally different: slowing of thermohaline overturn in the North Atlantic Ocean is expected to decrease northward heat transport by the ocean and to induce warming of the tropical Atlantic, whereas atmospheric greenhouse forcing should cause roughly synchronous global temperature changes. So these two mechanisms of climate change should be distinguishable by the timing of surface-water temperature variations relative to changes in deep-water circulation. Here we present a high-temporal-resolution record of sea surface temperatures from the western tropical North Atlantic Ocean which spans the past 29,000 years, derived from measurements of temperature-sensitive alkenone unsaturation in sedimentary organic matter. We find significant warming is documented for Heinrich event H1 (16,900-15,400 calendar years BP) and the Younger Dryas event (12,900-11,600 cal. yr BP), which were periods of intense cooling in the northern North Atlantic. Temperature changes in the tropical and high-latitude North Atlantic are out of phase, suggesting that the thermohaline circulation was the important trigger for these rapid climate changes.

title: NOAA/WDS Paleoclimatology - Briffa et al. 1992 Western North America Gridpoint and Regional Summer Temperature Reconstructions

description: Summer half-year (April-September) mean temperatures are reconstructed across western North America between 1600 and 1982. The reconstructions, ultimately in the form of gridpoint anomaly time series, are produced using a principal-components regression technique to relate variability in a network of up to 53 high-elevation maximum latewood-density chronologies to a number of important temperature principal-component amplitude series. The reconstructions are of good quality over the area between 35° and 55°N but are subject to large uncertainty north of 55°N, particularly prior to 1750. Four regional time series, the average of between two and six gridpoint series—British Columbia and the Pacific Northwest, California, eastern Rockies and northern High Plains, and the Southwest deserts—plus one more-extensive western United States series are presented and described. Examples of individual-year and decadal-mcan anomaly maps are illustrated, and the results of preliminary spectral analyses of the regional time series are described.
description: Reconstructions of summer temperatures at each of 24 grid point locations in the western U.S. and five regional reconstructions. As the 53-site reconstructions are better than those from the 23 sites a 1600-1982 series for any region should be derived from the 23 site reconstruction for 1600-1749 and the 53 site one for 1750-1982. °C anomalies relative to the 1951-70 base period.

title: NOAA/WDS Paleoclimatology - Heimerdalsvatnet, Norway 7800 Year Multiproxy Lake Sediment Data

description: This study takes a comprehensive approach to characterizing the isolation sequence of Heimerdalsvatnet, a coastal lake in the Lofoten Islands, northern Norway. We use established methods and explore new techniques to assess changes in marine influence. Bathymetric and sub-bottom profiles were acquired to examine basin-wide sedimentation and a 5.8 m sediment core spanning the last 7800 cal yr BP was analyzed.  We measured magnetic susceptibility, bulk organic matter properties, molecular biomarkers, diatom assemblages, and elemental profiles acquired by scanning X-ray fluorescence. These characteristics of the sediment reflect detailed changes in salinity and water column conditions as the lake was progressively isolated. Three distinct litho/chemo-stratigraphic units represent a restricted marine phase (7800–6500 cal yr BP), a transitional phase characterized by intermittent marine influence (6500-4900 cal yr BP), and complete isolation and freshwater sedimentation (4900 cal yr BP to present). Although there are uncertainties in the estimate of the threshold elevation of the lake, the timing of these phases generally corresponds with previous interpretations of the local relative sea-level history. This record captures sea-level regression following the Tapes transgression and supports the interpretation of a subsequent sea-level stillstand, dated in Heimerdalsvatnet from 6500 to 4900 cal yr BP.

title: NOAA/WDS Paleoclimatology - Lake Silvaplana, Switzerland 1000 Year Chironomid Inferred Temperature

description: Fossil chironomids (non-biting midges) from varved Lake Silvaplana, Switzerland, were used to reconstruct climate (mean July air temperatures) during the last millennium. At the beginning of the record, corresponding to the last part of the "Medieval Climate Anomaly" (MCA) (here the period between ca 1032 and 1262 AD), the chironomid-inferred mean July air temperatures were 1 °C warmer (p < 0.01) than the climate reference period (1961-1990). The "Little Ice Age" seems to have been separated into three phases: significantly colder (-1.1 °C in average, p< 0.001) temperatures were inferred between ca 1262 and 1481 AD, between ca 1514 and 1718 AD (-1.2 °C in average, p< 0.001) and between ca 1734 and 1782 AD (-0.6 °C in average, p< 0.1). Although the average temperature changes inferred by chironomids were within the error of prediction (1.5 °C) of the chironomid-temperature inference model used for reconstruction, the pattern of temperature changes corresponds well with records of the past millennium in Switzerland, in Europe and in the Northern Hemisphere. The average inferred July temperatures between ca 1900 and 2001 AD were significantly warmer (p < 0.05) than the climate reference period (1961-1990) by 1 °C which is in agreement with the instrumental data. The inferred July temperatures were in the same range as the inferred temperatures during the last part of the MCA suggesting that during the 20th century, at Lake Silvaplana, the chironomid-inferred temperatures do not exceed the natural climate variability of the past millennium.

title: NOAA/WDS Paleoclimatology - Law Dome Ice Core 500 Year Lead Isotope and Barium Data

description: Lead isotopic compositions and Pb and Ba concentrations have been measured in ice cores from Law Dome, East Antarctica, covering the past 6500 years. ‘Natural’ background concentrations of Pb (∼0.4 pg/g) and Ba (∼1.3 pg/g) are observed until 1884 AD, after which increased Pb concentrations and lowered 206Pb/207Pb ratios indicate the influence of anthropogenic Pb. The isotopic composition of ‘natural’ Pb varies within the range 206Pb/207Pb=1.20–1.25 and 208Pb/207Pb=2.46–2.50, with an average rock and soil dust Pb contribution of 8–12%. A major pollution event is observed at Law Dome between 1884 and 1908 AD, elevating the Pb concentration four-fold and changing 206Pb/207Pb ratios in the ice to ∼1.12. Based on Pb isotopic systematics and Pb emission statistics, this is attributed to Pb mined at Broken Hill and smelted at Broken Hill and Port Pirie, Australia. Anthropogenic Pb inputs are at their greatest from ∼1900 to ∼1910 and from ∼1960 to ∼1980. During the 20th century, Ba concentrations are consistently higher than ‘natural’ levels and are attributed to increased dust production, suggesting the influence of climate change and/or changes in land coverage with vegetation.

title: NOAA/WDS Paleoclimatology - Kaiser - Daettnau 2 Late Glacial Subfossil - PISY - ITRDB SWIT196

description: Lateglacial and Holocene tree-ring chronologies are unique archives, which provide various information on past environments on a true annual time scale. Changes in ring-width can be related to past climate anomalies and dendrodated wood provides an ideal source for radiocarbon calibration. We present a 1051 year tree-ring chronology from the Late Glacial, built from subfossil Scots pines (Pinus sylvestris) that grew in different regions of Central and Southern Europe. Through a series of high-precision radiocarbon measurements we obtained a floating radiocarbon chronology, which allowed accurate wiggle-matching to the INTCAL98 calibration curve. The trees show a coherent pattern in ring-width variations throughout Central Europe, and extending into the Mediterranean, which indicates a strong external climatic factor, most probably temperature during the growing season. We identified major growth events, which appear synchronous with events seen in isotopic and tracer signals in the Greenland ice cores and with changes in the strength of upwelling in the Cariaco Basin.

title: BreastCancer2025_COC_JT

description: Data extracted from the hospital-based cancer registry of Cameroon Oncology Center from January 1, 2020 to March 30, 2025. The dataset is specific for breast cancer. The main findings from this dataset are summarized in two abstracts:
ABSTRACT 1
Background
Breast cancer (BC) is the most frequent cancer in sub-Saharan Africa and the leading cause of all cancer-related deaths. Late presentation at advanced stage of disease is characteristic of low- and middle-income countries (LMICs). The presence and specific sites of metastatic disease affects treatment planning, response and prognosis. Given the genetic heterogeneity of metastatic breast cancer (mBC), this study aspired to determine the prevalence, determinants and tropism in a Central African setting.
Methods
Data was extracted from a prospectively collected hospital-based cancer registry at a specialized university-affiliated oncology center. Multivariable logistic regression modeling was used to determine the predictors of tumor spread whilst the pattern of spread was illustrated using a Sankey diagram. All statistical tests were two-tailed and the threshold for significance was set at 0.05.
Results
Data was extracted from the medical records of 271 patients with breast cancer. The sex-ratio was 1:270 and median age (range) 47 (16-91) years. A total of 148/271 (54.6%) BC occurred at the left breast (p&lt;0.01). Invasive ductal carcinoma (IDC) accounted for 76.4% (204/267) of all histologic subtypes whilst triple negative breast cancer (TNBC) was the predominant molecular subtype (55.9%, 146/261). Tumor staging at baseline was as follows: stage I, 2.7% (17/271); stage II, 36.2% (98/271); stage III, 43.5% (118/271); stage IV, 14% (38/271). During follow-up there was imaging evidence of metastasis in 40.2% (109/271) of patients. mBC was independently associated to histologic (p=0.03) and molecular subtypes (p&lt;0.01), with IDC and TNBC representing 83.9% (89/106) and 72.4 % (76/105) of all cases of metastases respectively. In the multivariable modeling patient’s age &lt;42 years (aOR = 2.1, 95%CI: 1.1-4.1, p= 0.03) and TNBC (aOR = 2.4, 95%CI: 1.3- 4.5, p&lt;0.01) were associated to mBC. Right breast cancers were more likely to spread to the lungs and liver (p&lt;0.01).
Conclusion
TNBC is predominant in the study population and with young age are associated with mBC and thus poor outcomes. Strategies that improve the uptake of screening and facilitate access to quality care are likely to reduce BC disease burden in LMICs.
