title: NOAA/WDS Paleoclimatology - North fire data from Green Cr. - IMPD USGRN002

description: There have been few fire history studies of eastern Sierra Nevada forests in California, USA, where a steep elevation gradient, rain shadow conditions, and forest stand isolation may produce different fire regimes than those found on the range's western slope. We investigated historic fire regimes and potential climate influences on four forest types ranging in elevation from 1700 m to 3200 m on the Sierra Nevada's eastern slope and the White Mountains' western slope. Sample areas (approximately 15 ha to 45 ha) had mean site fire return intervals ranging from 4.8 yr to 16.9 yr across ten Jeffrey pine (Pinus jeffreyi Balf.) sites, and 13.4 yr to 45.7 yr across four high elevation lodgepole (P. contorta Douglas ex Louden), foxtail (P. balfouriana Balf.) and bristlecone (P. longaeva D.K. Bailey) pine sites. At most sites (13 of 14), >50 % of fire events occurred in late or dormant season wood. Twentieth century fire return intervals increased at some sites, while other sites continued to record frequent fire events into the 1950s. Years where two or more sites recorded fire events on two or more trees were correlated with drought conditions forecast by the Palmer Drought Severity Index (PDSI) in our sample locations at and north of Mammoth Lakes. The lower Sierra Nevada crest due west of these locations may connect weather patterns with western slope conditions more than at our southern eastside sample sites, which were not significantly correlated with PDSI. Our results suggest eastern Sierra Nevada Jeffrey pine forests have similar seasonality and fire return intervals as some western slope forests, but site fire history can be influenced by stand isolation, historical use, and local rain shadow conditions.

title: NOAA/WDS Paleoclimatology - Alaska Lake Sediment Data and Holocene Climate Reconstructions

description: Analyses of sediment cores from two lakes in the central Brooks Range provide temperature and moisture balance information for the past ~8500 cal yr at century-scale resolution. Two methods of oxygen isotope analysis are used to reconstruct past changes in the effective moisture (precipitation minus evaporation) and temperature. Effective moisture is inferred from oxygen isotope ratios in sediment cellulose from Meli Lake (area ~0.13 km2, depth 19.4 m). The lake has a low watershed-to-lake-area ratio and significant evaporation relative to input. Summer temperature shifts are based on oxygen isotope analyses of endogenic calcite from Tangled Up Lake (area ~0.25 km2, depth 3.5 m). This basin has a larger watershed-to-lake-area ratio and less evaporation relative to input. Sediment oxygen isotope analyses from the two sites indicate generally more arid conditions than present prior to ~6000 cal yr B.P. Subsequently, the region became increasingly wet. Temperature variability is recorded minimally at centennial scale resolution with values that are generally cool for the past ~6700 cal yr. The timing and direction of climate variability indicated by the oxygen isotope time series from Meli and Tangled Up lakes are consistent with previously established late Holocene glacier advances at ~5000 cal yr B.P. in the central Brooks Range, and high lake-levels at Birch Lake since ~5500 cal yr B.P. This unique use of oxygen isotopes reveals both moisture balance and temperature histories at previously undetected high-resolution temporal scales for northern Alaska during the middle to late Holocene.

title: NOAA/WDS Paleoclimatology - Dome Fuji - 338KYr Wet Extraction CO2 Data

description: A deep ice core drilled at Dome Fuji, East Antarctica was analyzed for the CO2 concentration using a wet extraction method in order to reconstruct its atmospheric variations over the past 320 kyr, which includes three full glacial—interglacial climatic cycles, with a mean time resolution of about 1.1 kyr. The CO2 concentration values derived for the past 65 kyr are very close to those obtained from other Antarctic ice cores using dry extraction methods, although the wet extraction method is generally thought to be inappropriate for the determination of the CO2 concentration. The comparison between the CO2 and Ca2× concentrations deduced from the Dome Fuji core suggests that calcium carbonate emitted from lands was mostly neutralized in the atmosphere before reaching the central part of Antarctica, or that only a small part of calcium carbonate was involved in CO2 production during the wet extraction process. The CO2 concentration for the past 320 kyr deduced from the Dome Fuji core varies between 190 and 300 ppmv, showing clear glacial—interglacial variations similar to the result of the Vostok ice core. However, for some periods, the concentration values of the Dome Fuji core are higher by up to 20 ppmv than those of the Vostok core. There is no clear indication that such differences are related to variations of chemical components of Ca2×, microparticle and acidity of the Dome Fuji core.

title: NOAA/WDS Paleoclimatology - Ziegler and Murray 2007 Central Pacific ODP1215 Cenozoic Elemental Concentration Data

description: We measured the elemental concentrations of 69 sediment samples collected at Ocean Drilling Program Site 1215 and employed a suite of statistical methods and elemental ratios to quantify the lithogenic, biogenic, and authigenic/hydrogenous/hydrothermal (AHH) components. We show that the changes in their abundance record (1) northwestward migration of the Pacific Plate, (2) changes in climatic and oceanographic processes associated with the transition from the Eocene “greenhouse” into the Oligocene “icehouse,” and (3) changes in Pacific spreading rates and plate reorganization. The distributions of three separate lithogenic end-members depend on the latitudinal positioning of the site underneath the different wind belts. Locations north of 22°N received material from Asia, which was transported to the central Pacific via the westerlies. Locations between 20° and 22°N display a silicic volcanic composition and may reflect the boundary between westerlies and northeast trade winds. Locations south of 20°N are geochemically (e.g., Cr/Ta, Sc/Th, etc.) distinct from locations north of 22°N and suggest a North American origin. Rb/Sc significantly increases from values of 2.8 g g−1 at ∼20–22 Ma to 5.7 g g−1 in the modern, recording the development of the east Asian monsoon and formation of Asian loess. During the early to mid-Eocene (53–54 Ma), when Site 1215 was located at ∼11°–13°N and was above the carbonate compensation depth, export production increased by 40–55% and was ∼25% greater than the modern value at 9°N. The AHH component dominated from late Eocene to the late Miocene and during the late Eocene may have been driven by elevated hydrothermal activity during increased seafloor spreading.

title: NOAA/WDS Paleoclimatology - EPICA Dome C - 800KYr Methane Data

description: Atmospheric methane is an important greenhouse gas and a sensitive indicator of climate change and millennial-scale temperature variability. Its concentrations over the past 650,000 years have varied between ~350 and ~800 parts per 10^9 by volume (p.p.b.v.) during glacial and interglacial periods, respectively. In comparison, present-day methane levels of ~1,770 p.p.b.v. have been reported. Insights into the external forcing factors and internal feedbacks controlling atmospheric methane are essential for predicting the methane budget in a warmer world. Here we present a detailed atmospheric methane record from the EPICA Dome C ice core that extends the history of this greenhouse gas to 800,000 yr before present. The average time resolution of the new data is ~380 yr and permits the identification of orbital and millennial-scale features. Spectral analyses indicate that the long-term variability in atmospheric methane levels is dominated by ~100,000 yr glacial–interglacial cycles up to ~400,000 yr ago with an increasing contribution of the precessional component during the four more recent climatic cycles. We suggest that changes in the strength of tropical methane sources and sinks (wetlands, atmospheric oxidation), possibly influenced by changes in monsoon systems and the position of the intertropical convergence zone, controlled the atmospheric methane budget, with an additional source input during major terminations as the retreat of the northern ice sheet allowed higher methane emissions from extending periglacial wetlands. Millennial-scale changes in methane levels identified in our record as being associated with Antarctic isotope maxima events are indicative of ubiquitous millennial-scale temperature variability during the past eight glacial cycles.

title: NOAA/WDS Paleoclimatology - Moon Lake 2,000 Year Diatom Salinity-Drought Data

description: Extreme large-scale droughts in North America, such as the 'Dust Bowl' of the 1930s, have been infrequent events within the documented history of the past few hundred years, yet this record may not be representative of long-term patterns of natural variation of drought intensity and frequency. In the Great Plains region of central North America, historical droughts have persisted longer than in any other part of the United States, but no detailed records of drought patterns in this region have hitherto been obtained that extend beyond the past 500 years. Here we present a reconstruction of drought intensity and frequency over the past 2,300 years in the Northern Great Plains, based on lake salinity fluctuations inferred from fossil diatom assemblages. This record, of sub-decadal resolution, suggests that extreme droughts of greater intensity than that of the 1930s were more frequent before AD 1200. This high frequency of extreme droughts persisted for centuries, and was most pronounced during AD 200-370, AD 700-850 and AD 1000-1200. We suggest that before AD 1200, the atmospheric circulation anomalies that produce drought today were more frequent and persistent.
