A vegetation history of the far north of New Zealand during the Late Otira (last) glaciation
. Mixed kauri/podocarp/angiosperm forest was present at times during the late Otiran (and Araniuan) and no evidence was found for substantial loss of forest.
Geomorphological evidence for fluvial change during the Roman period in the lower Rhone valley (southern France)
The hydrological and geomorphological dynamics of the lower Rhone river are studied during the Roman period. The crossing of archaeological and radiocarbon dating methods allow to study events at a pluridecadal to centennial scale. Therefore the AA
Sea-surface temperature estimates for the tropical western Pacific during the last glaciation and their implications for the Pacific warm pool
Twenty deep-sea sediment cores from the western Pacific between 30°N and 30°S provide evidence of sea-surface temperature (SST) changes throughout the tropics and subtropics. The results indicate that a western Pacific warm pool existed during
the last glacial maximum (LGM), providing a heat and moisture source for a Walker Circulation cell similar to that of today. The AA. propose that a steeper lapse rate existed during the last glacial maximum and that this can explain at least part

Surface circulation of the Indian Ocean during the last glacial maximum, approximately 18,000 yr B. P.
A seasonal reconstruction of the Indian Ocean during the last glacial maximum (18,000 yr B. P.) reveals thats its surface circulation and sea surface temperature patterns were significantly different from the modern Indian Ocean. This reconstruction
is based on the planktonic foraminiferal biogeography and estimated sea surface temperatures in 42 Indian Ocean samples. Compared to modern conditions, the polar front was 5 to 10 latitude further north during the last glacial maximum| the Subtropical
Convergence was 2 to 5 latitude further north. The West Australian Current was more intense as part of the West Wind Drift was deflected northward along the coast of Australia. The Agulhas Current was cooler and weaker during the summer and more saline
and subtropical during the winter. In general, the low latitudes underwent little temperature change. The western Arabian Sea was warmer which implies less upwelling and a weaker Southwest Monsoon. On the average, the Indian Ocean was 1.9C cooler in February
and 1.7C cooler in August during the last glacial maximum.

Sea-surface temperatures and the history of monsoon upwelling in the Northwest Arabian Sea during the last 500,000 years
ocean, a 500,000-yr record of productivity at ODP Site 723 shows consistently stronger upwelling during interglaciations than during glaciations. The objective is to reconstruct the history of SST (Sea-Surface Temperatures) and productivity variations
The midden data suggest significant environmental and floristic changes in the White Mountain region. During the last 20,000 yr, cold conditions during the late Wisconsin glacial age gave way to a warm middle Holocene beginning ca. 8 000 yr B.P
. Conditions were probably warmer than at present during the middle Holocene, with the establishment of climates and plant communities similar to those of the present during the late Holocene.
Evidence of high sea level during isotope stage 5c in Queensland, Australia
age of 105,000 yr BP. The corals provide evidence of a sea stand near present sea level during isotope Stage 5c, which is considerably higher than previously suggested for this period. Their good condition implies that the overlying parabolic dune
is of comparable age and formed during that high stand of sea level. Also, the isotope age provides a maximum period for the development of giant podzols in the podzol chronosequences on coastal dunes in southern Queensland.

Similarities and dissimilarities between the dynamics of sand and dust during wind erosion of loamy sandy soil
The AA. examine the aeolian dynamics of sand and dust during a wind erosion event on loamy sandy soil in Northern Germany. The large percentage of dust (up to 32%) in the topsoil and the high frequency of wind erosion events make the region suitable
for studying the behaviour of both components simultaneously. The aim is to check whether differences exist in the patterns of erosion, transportation, deposition and accumulation (deposition minus erosion) during a single wind erosion event.
