This chapter provides an extensive review of paleomonsoon variability on millennial-to decadal time scales in various archives other than loess, including speleothems, lake sediments, peat deposits, desert deposits, marine sediments, corals, ice cores, tree rings, pollen archives and historical documents. Case studies will be presented to introduce the major proxy indexes associated with these archives, and the reconstructed history of Asian monsoon variability. Advances in the study of monsoon variability and the peculiarity of different archives will also be introduced in this chapter.Keywords Speleothems · Lake sediments · Peat · Desert · Marine sediments · Coral · Ice cores · Tree ring · Pollen · Historical documents Overview of Various Paleoclimate ArchivesAs described in the previous chapter, the eolian loess sequence, a unique geological archive in the world, plays an important role in studying the climatic and environmental changes in China as it documents the variability of both Asian monsoon and the aridification of inland Asia. It has the advantages of being relatively continuous and long-lasting for studying the monsoon changes and inland aridifications on tectonic and orbital time scales, and even has the potential for studies of monsoon variations on millennial time scales at some sites. However, other geo-biological archives and historical records are also essential in studying the Asian monsoon changes, as they provide indispensable information for fully understanding Asian monsoon changes and its dynamic forces and environmental effects, especially on the millennial to decadal time scales. For example, taking advantage of high-precision absolute U-series dating, speleothems from karst caves, provide the ages of the abrupt events that occurred within the Asian monsoon regions and make it possible to correlate these events with global climate changes, enhancing greatly our understanding of the linkage between Asian monsoon and global climate change. With multiple proxies, lake sediments are good at providing the integrated information on hydrology, weathering processes, biomass and other aspects within the drainage systems. Coral records may indicate the changes in moisture supply from the tropical ocean, ocean circulation, sea surface temperature and other parameters linked closely with monsoon climate. Tree-ring records provide annual changes of regional temperature, precipitation and the hydrological environment, and are the basis to fully describe the present global warming and the anthropogenic contribution. As the direct index of vegetation, pollen assemblages indicate the succession of vegetation associated with monsoon changes, revealing variations in moisture availability and temperature. Therefore, studies of these various archives, as well as peatbogs, ice cores, marine and desert deposits and historical records, greatly expanded our knowledge of the variability of Asian monsoons and their driving forces.This chapter will focus on various archives used in the study of Asian mon...

Automated static image analysis and newly introduced evaluation techniques were applied in this paper to identify Saharan dust material in the unique sand-paleosol sequence of Fuerteventura (Canary Islands). Measurements of ~50,000 individual mineral particles per samples provided huge amount of granulometric data on the investigated sedimentary units. In contrast to simple grain size and shape parameters of bulk samples, (1) parametric curve-fitting allowed the separation of different sedimentary populations suggesting the presence of more than one key depositional mechanisms. Additional (2) Raman-spectroscopy of manually targeted individual particles revealed a general relationship among grain size, grayscale intensity and mineralogy. This observation was used to introduce the (3) intensity based assessment technique for identification of large number of quartz particles. The (4) cluster and (5) network analyses showed that only joint analysis of size, shape and grayscale intensity properties provided suitable results, there is no specific granulometric parameter to distinguish Saharan dust due to their irregular shape characteristics. The presented methods allowed the separation of Saharan dust-related quartz grains from local sedimentary deposits, but due to the lack of robust granulometric characterization of coarsest fractions and due to the diverse geochemical properties of North African sources, exact volumetric amount of deposited dust material and sedimentation rates could not be determined from these data.

“…The δ 18 O and δ 13 C speleothem data from Dongge Cave in southern China studied by Dykoski et al (2005) has shown periodicities of 208, 86 and 11 yrs in monsoon strength over the last 16,000 years. An analysis by Lim et al (2005) of a high-resolution sediment record from Korea revealed periodicities of 280, 210 and 137 yrs in northwesterly winter monsoonal winds over at least the last 6,500 years. Kitagawa and Matsumoto (1995) examined δ 13 C variations, which they interpreted as a temperature proxy, in Japanese cedars (Cryptomeria japonica) in southern Japan over the last two millennia and found significant temperature periodicities of approximately 187, 89, 70, 55, and 44 yrs.…”

Multispectral analysis of Northern Hemisphere temperature records over the last five millennia

Aiming to describe spatio-temporal climate variability on decadal-to-centennial time scales and longer, we analyzed a data set of 26 proxy records extending back 1000 to 5000 years; all records chosen were calibrated to yield temperatures. The seven irregularly sampled series in the data set were interpolated to a regular grid by optimized methods and then two advanced spectral methods -namely singular-spectrum analysis (SSA) and the continuous wavelet transform -were applied to individual series to separate significant oscillations from the high noise background. This univariate analysis identified several common periods across many of the 26 proxy records: a millennial trend, as well as oscillations of about 100 and 200 yr, and a broad peak in the 40-70-yr band. To study common NH oscillations, we then applied Multichannel SSA (MSSA). Temperature variations on time scales longer than 600 yr appear in our analysis as a dominant trend component, which shows climate features consistent with the Medieval Warm Period and the Little Ice Age. Statistically significant NH-wide peaks appear at 330, 250 and 110 yr, as well as in a broad 50-80-yr band. Strong variability centers in several bands are located around the North Atlantic basin and are in phase opposition between Greenland and Western Europe.
