This study reveals unprecedented burning in tropical peatlands during the 20th century, mainly expressed in the Indomalayan and Australasian regions, emphasising regional variability in peatland burning and its links to modern human activities. Before this period, tropical peatland burning largely followed changes in global temperature and was ...

Seasonal Changes in Marine Archaeal Tetraether Lipid Export Depth Linked to Net Primary Productivity
Abstract Marine ammonia oxidizing archaea (AOA) produce isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) which form the basis of seawater temperature proxy TEX86. Although most studies use TEX86 for sea surface temperature (SST) reconstructions, maximum GDGT production occurs at and below the nitracline. Moreover, sedimentary GDGT‐2/GDGT‐3

Abstract The Indo‐Pacific Gateway is a narrow tropical passage connecting the Pacific and Indian Oceans, and alterations in its topographic configuration can significantly influence the volume of water exchanged between the two oceans through the Indonesian Throughflow (ITF).

Alkenone and TEX86 data for MIS 6 to 5 on the Brazilian Margin
We generated alkenone- and TEX86- based paleotemperature estimates for MIS 6-5 in core M125-55-7 (offshore Eastern Brazil) to text whether previously generated foraminiferal Mg/Ca SST are seasonaly biased.

Evaluating the Reliability of Grain‐Size Sorting for Organic Biomarker Analysis
Abstract Organic and inorganic geochemical proxies are fundamental for interpreting past climate variability. For inorganic analysis, marine sediments are often size fractionated to isolate foraminifera, while organic analysis employs subsamples of bulk sediment.

TEX86 in sinking particles in three eastern Atlantic upweling regimes
Seasonal variations in fluxes of isoprenoid glycerol dialkyl glycerol tetraethers (GDGTs) and the estimated temperatures based on TEX86 were examined in sinking particles collected using moored sediment traps in the eastern Atlantic upwelling regions. In

Hydroxylated isoprenoid GDGTs (OH‐GDGTs) have emerged as a novel tool for reconstructing sea surface temperatures. However, when using marine OH‐GDGT calibration in lacustrine settings, it leads to a significant overestimation of temperatures ...

Altered Ocean Temperature Gradients Are Key to Miocene South Asian Monsoon Evolution
Abstract Indian Ocean sea surface temperature (SST) gradients influence South Asian summer monsoon (SASM) strength. Middle Miocene proxy records show reversed Arabian Sea zonal gradients (warmer west than east) and reduced Indian Ocean meridional gradients compared to today—patterns coupled models cannot reproduce, hindering accurate SASM simulation ...
