“…Six major Holocene changes in vegetation have been identified by Jalut et al (2000) in a transect covering southeast France and south-west Spain. They correspond to aridification phases that took place between 10.9 9.7 cal ka BP, 8.4 7.6 cal ka BP, 5.3 4.2 cal ka BP, 4.3 3.4 cal ka BP, and 2.8 1.7 cal ka BP.…”

Sea level and clima te changes archived in various coastal environments during the last part of the last glacial and present interglacial periods are investigated by interpolating available geomorphology, sedimentology, palaeontology and geochronology data. The coastal response to these changes depended on the environment and geographic location. Changes of sea level during the rising, transgressive phase are well recorded in the sedimentary filling of the estuaries, whereas during the phase of highstand they are best recorded in beach-barrier environments. The postglacial rise of sea level took place in two phases: a rapid rise until 6500 cal BP, and a second phase of near stability with minor oscillations of metric magnitude. Regarding climate changes, there is no record of changing temperatures in the coastal zones of southern Spain, although there is in precipitation and wind intensityjvelocity. After 7-5 cal ka BP, the general climatic trend towards aridity was punctuated by several short-lived (centennial) episodes of increased aridity that occurred with a millennial cycle, often coincident with Bond cool events and, in sorne cases, with decreases of sea surface temperatures. The absence of human in ter ventio n in vegetation composition until 2000 BP suggests that most environmental coastal shifts were climatically driven,

“…The last 4000 yr of this time interval are characterized by several climatic fluctuations, the best identified among them being the Late Bronze Age-Iron Age (LBA, 3600-2600 cal yr BP; van Geel et al, 1996), the Roman Humid Period (RHP, 2600-1600 cal yr BP; Issar, 2003), the Dark Ages (DA, 1600-1150 cal yr BP; Berglund, 2003), the Medieval Climate Anomaly (MCA, 1150-650 cal yr BP;Lamb, 1965;Hughes and Diaz, 1994) and the LIA (650-150 cal yr BP; Bradley and Jones, 1993). In this work we integrated data from two different marine records from the western Algerian-Balearic Basin.…”

Abstract. Climate variability in the western Mediterranean is reconstructed for the last 4000 yr using marine sediments recovered in the west Algerian-Balearic Basin, near the Alboran Basin. Fluctuations in chemical and mineralogical sediment composition as well as grain size distribution are linked to fluvial-eolian oscillations, changes in redox conditions and paleocurrent intensity. Multivariate analyses allowed us to characterize three main groups of geochemical and mineralogical proxies determining the sedimentary record of this region. These three statistical groups were applied to reconstruct paleoclimate conditions at high resolution during the Late Holocene. An increase in riverine input (fluvial-derived elements -Rb/Al, Ba/Al, REE/Al, Si/Al, Ti/Al, Mg/Al and K/Al ratios), and a decrease in Saharan eolian input (Zr/Al ratio) depict the Roman Humid Period and the Little Ice Age, while drier environmental conditions are recognized during the Late Bronze Age-Iron Age, the Dark Ages and the Medieval Climate Anomaly. Additionally, faster bottom currents and more energetic hydrodynamic conditions for the former periods are evidenced by enhanced sortable silt (10-63 µm) and quartz content, and by better oxygenated bottom waters -as reflected by decreasing redox-sensitive elements (V/Al, Cr/Al, Ni/Al and Zn/Al ratios). In contrast, opposite paleoceanographic conditions are distinguished during the latter periods, i.e. the Late Bronze Age-Iron Age, the Dark Ages and the Medieval Climate Anomaly. Although no Ba excess was registered, other paleoproductivity indicators Correspondence to: V. Nieto-Moreno (vanesanieto@ugr.es) (total organic carbon content, Br/Al ratio, and organometallic ligands such as U and Cu) display the highest values during the Roman Humid Period, and together with increasing preservation of organic matter, this period exhibits by far the most intense productivity of the last 4000 yr. Fluctuations in detrital input into the basin as the main process managing deposition, reflected by the first eigenvector defined by the Principal Component Analyses, point to solar irradiance and the North Atlantic Oscillation variability as the main driving mechanisms behind natural climate variability over decadal to centennial time-scales for the last 4000 yr.
