title: NOAA/WDS Paleoclimatology - Heyerdahl fire data from Imnaha - IMPD USIRC001

description: Our objective was to infer the controls of spatial variation in historical fire regimes. We reconstructed a multicentury history of fire frequency, size, season, and severity from fire scars and establishment dates of 1426 trees sampled on grids in four watersheds (-64 plots, over -1620 ha each) representative of the Blue Mountains, Oregon and Washington, USA. The influence of regional climate, a top-down control, was inferred from among-watershed variation in fire regimes, while the influence of local topography, a bottom-up control, was inferred from within-watershed variation. Before about 1900, fire regimes varied among and within watersheds, suggesting that both top-down and bottom-up controls were important. At the regional scale, dry forests (dominated by ponderosa pine), burned twice as frequently and earlier in the growing season in southern watersheds than in northern watersheds, consistent with longer and drier fire seasons to the south. Mesic forests (dominated by subalpine fir or grand fir) probably also burned more frequently to the south. At the local scale, fire frequency varied with different parameters of topography in watersheds with steep terrain, but not in the watershed with gentle terrain. Frequency varied with aspect in watersheds where topographic facets are separated by significant barriers to fire spread, but not in watersheds where such facets interfinger without fire barriers. Frequency varied with elevation where elevation and aspect interact to create gradients in snow-cover duration and also where steep talus interrupts fuel continuity. Frequency did not vary with slope within any watershed. The presence of both regional-scale and local-scale variation in the Blue Mountains suggests that top-down and bottom-up controls were both important and acted simultaneously to influence fire regimes in the past. However, an abrupt decline in fire frequency around 1900 was much greater than any regional or local variation in the previous several centuries and indicates that 20th-century fire regimes in these watersheds were dramatically affected by additional controls such as livestock grazing and fire suppression. Our results demonstrate the usefulness of examining spatial variation in historical fire regimes across scales as a means for inferring their controls.

title: NOAA/WDS Paleoclimatology - Morley and Heusser 1997 Orbital Forcing in East Asian Monsoon Climates Data

description: Proxy records of northeast Asian precipitation (marine pollen) and northwest Pacific sea surface temperatures (marine fauna) contain concentrations of variance (frequency peaks) coincident with those of orbital variations (eccentricity, obliquity, and precession). Time series of these monitors of various components of the east Asian monsoon system are coherent with changing solar insolation and climate boundary conditions (ice volume, snow cover, albedo) at 41- and 23-kyr frequencies. Winter sea surface temperature (WSST) maxima are in phase with global ice volume minima at all three Milankovitch frequencies (100-, 41-, and 23-kyr periods). WSST maxima are also linearly related to summer insolation at 30°N, lagging radiation maxima by ∼55° (∼3.5 kyr) across the precessional frequency band (23-kyr period). Our east Asian monsoon rainfall indicator (% Cryptomeria) reaches highest values immediately following summer insolation maxima during periods of low ice volume (interglacials). Across the eccentricity frequency band (100-kyr period), % Cryptomeria maxima are in phase with ice volume minima. At the higher frequency of orbital precession, monsoon rainfall lags both summer radiation maxima (∼125°; ∼8 kyr) and ice volume minima (∼60°; ∼3.8 kyr). Whereas much of the variation in northwest Pacific WSST can be attributed to summer radiation forcing and changes in global climate, mechanisms driving east Asian monsoon precipitation are more complex, involving other (possibly internal) factors.

title: NOAA/WDS Paleoclimatology - Ortiz et al 1999 North Atlantic Spectral Reflectance Data

description: Diffuse reflectance records from Feni Drift in the North Atlantic faithfully record sediment percent carbonate. A high-resolution, reflectance-based age model for these sediments derived from an orbitally tuned age model for western equatorial Atlantic, Ceara Rise sediments was generated by spectral frequency mapping. Power spectra of the Feni Drift record indicate statistically significant sub-Milankovitch cyclicity at 7.6–8.4 and 4.8–6.1 kyr. We infer that these ∼8 and ∼5 kyr cycles document a linkage between North and equatorial Atlantic climate given our ability to correlate these records. These climate cycles influence Atlantic basin carbonate prior to the intensification of Northern Hemisphere glaciation and thus must arise from some portion of the climate system other than the dynamics of large ice sheets. The presence of these peaks, which could be related to equatorial clipped precession, implies a possible non-linear response to Milankovitch forcing.

title: NOAA/WDS Paleoclimatology - Climate Model Output, LGM with Modern Ocean Heat Transport

description: A series of climate simulations using an atmospheric general circulation model shows that maintaining ocean heat transport at close to present-day values, but with otherwise glacial boundary conditions, leads to an enhanced cooling, particularly in the tropics. This is in agreement with recent geochemical evidence from fossil corals, ground waters, and ice. Near-modern ocean heat transport may have been sustained in all ocean basins during the Last Glacial Maximum in order to balance the formation and export of Glacial North Atlantic Intermediate Water.

title: NOAA/WDS Paleoclimatology - CCMO General Circulation Model Output Data Set

description: General circulation model experiments at 3000-year intervals for the past 18 000 years were made to estimate the magnitude, timing, and pattern of the climatic response to prescribed changes of orbital parameters (date of perihelion, axial tilt, eccentricity) and glacial-age lower boundary conditions (ice sheets, land albedo, sea ice and sea surface temperature). The experiments used the Community Climate Model (CCM) of the National Center for Atmospheric Research (NCAR). The response of monsoon circulations and tropical precipitation to the orbitally produced solar radiation changes was much larger than the response to changes of glacial-age boundary conditions. The continental interior of Eurasia was 2–4 K warmer in summer, and summer monsoon precipitation of North Africa-South Asia was increased by 10–20% between 12 000 and 6000 yr BP (before present) when perihelion occurred during northern summer (rather than in winter as now) and the earth's axial tilt was larger than now. Southern Hemisphere summer monsoons were weaker during the same period. In northern midlatitudes, glacial-age features such as the North American ice shed exerted a strong influence on the climate until 9000 yr BP. Much of the climatic change of the period 12 000 to 6000 yr BP can be described as an amplified (weakened) seasonal cycle in response to the larger (smaller) seasonal radiation extremes of the Northern (Southern) Hemisphere. Summers were warmer and winters colder in Northern Hemisphere lands, but there was little change in annual average temperature. However, because of the nonlinear relationship between saturation vapor pressure and temperature, the sensitivity of the hydrologic cycle to orbital parameter changes was larger in summer than in winter (and in the tropics rather than high latitudes); in the northern tropics, this led to a net increase in estimated annual average precipitation and precipitation minus evaporation. Many features of the results are in agreement with geologic evidence.

title: NOAA/WDS Paleoclimatology - Yamamoto et al. 2005 Northwestern Pacific 144KYr Alkenone SST Estimates

description: We have generated a high-resolution record of alkenone sea surface temperature (SST) between 10ŋ24 ka from Core MD01-2421 off central Japan, in the northwestern Pacific. The cooling by 5°C from 21 ka to 12.8 ka implies the equatorward shift of the subarctic boundary in the northwestern Pacific by ~2.8° in latitude. This shift was a result of the stronger summer Okhotsk High. The Okhotsk High was likely enhanced by the combined effects of El Niņo-like conditions in the tropical Pacific and the heating of the land surface of northeastern Siberia.

title: NOAA/WDS Paleoclimatology - South Atlantic Glacial Deep Water Cd/Ca and d13C Data

description: A depth transect of cores from 1268 to 3909 m water depth in the western South Atlantic are ideally situated to monitor the interocean exchange of deep water and variations in the relative strength of northern and southern sources of deep water production. Benthic foraminiferal Cd/Ca and δ13C data suggest that Glacial North Atlantic Intermediate Water (GNAIW) extended at least as far south as 28°S in the western South Atlantic. The core of nutrient-depleted water was situated at ∼1500 m, above and below water masses with higher nutrient concentrations. When examined in conjunction with published paired Cd/Ca and δ13C from intermediate depth cores from other basins, it appears that the extent of GNAIW influence on the intermediate waters of the world's oceans was less than suggested previously. Differentiating among possible pathways for the glacial deep ocean (>3 km) requires a better understanding of the controls on Cd/Ca and δ13C values of benthic foraminifera.
