An accurate analysis of the composition of stable isotopes is today an increasingly important
requirement in various fields of science (from the environmental to the medical field). Since …

Research into organic matter in speleothems has progressed recently to encompass new
analytical approaches and applications, which offer increased potential in areas such as …

Organic matter preserved in speleothems has the potential to reflect the changes of the
overlying vegetation and soil ecosystem. Here we report the first near 50-yr-resolution acid …

Abstract Cathedral Cave, Wellington, Australia, is a natural laboratory for studying water
movement and geochemical processes in the unsaturated zone by using artificial irrigation …

Speleothem stable carbon isotopes (δ 13 C carb) are used to reconstruct past environments,
but are a complex signal of karst, soil and plant processes. To help untangle these signals …

This study presents a novel method for the analysis of low molecular weight (LMW) fatty
acids in cave drip water and speleothems. The method development included optimization …

The analysis of δ 13 C in speleothem calcite is established as a palaeoenvironmental proxy,
but records can often be complex to interpret due to multiple controls on the signal. Here we …

Karst areas are widespread landforms present on all continents, formed by the dissolution of
carbonate or evaporite host rock. Little is known about the composition and nature of …

RATIONALE Dissolved organic carbon (DOC) plays an important role in carbon cycling,
making precise and routine measurement of δ13C values and DOC concentration highly …

The soil-derived organic matter incorporated in speleothems provides a proxy for the
impacts of climate and environmental changes on the surrounding catchment. These …
