Ocean Drilling Program Leg 155 Site 942 on the Amazon Fan is an ideal location for monitoring palaeoclimatic changes within a significant proportion of the Amazon Basin. We present n‐ alkane δ 13 C and taraxerol and laevoglucosan concentration records from this site covering the last 38 ka. The entire n ‐alkane δ 13 C record is constrained between −31‰ and −34‰, which is well within the isotopic range occupied by C 3 vegetatio...

The occurrence of a millennial‐scale bipolar climate seesaw has been documented in detail for the last glacial period and Termination. There is, however, debate whether it occurs during interglacials and if it does what influence it could have on future climate. We present here new evidence from a North East Atlantic Ocean deep‐sea core which supports the hypothesis for a Holocene bipolar climate seesaw. BENGAL Site 13078#16,...

Previous work has suggested that a species effect may be present in diatom oxygen isotope ratios ( δ 18 O diatom ). While predominantly attributed to be a size‐related species effect, currently the precise mechanism remains unknown. Here, two size fractions of diatoms (38–75 µm and >100 µm) covering the last 200 ka are analysed for δ 18 O from ODP Site 882 in the North‐West Pacific Ocean. Synchronous variations of up to 13‰ oc...

The paleoenvironmental context of plant and animal species evolution (including glacial migrations and population separations) is based on a very patchy and incomplete paleo‐phytogeographic record. It was our objective, therefore, to provide an additional source for paleovegetation comparison by presenting simulations from a state‐of‐the‐art fully coupled earth system model (HadCM3LC). We simulated potential paleovegetation di...
