This paper provides an overview of stable isotope analysis (H, C, N, O, Si) of the macro-and
microscopic remains from aquatic organisms found in lake sediment records and their …

Measurements of diatom oxygen isotopes (δ18Odiatom) hold the potential to provide an
important additional source of palaeoceanographic information in regions depleted in …

The development of a rapid and non-destructive method to assess purity levels in samples
of biogenic silica prior to geochemical/isotope analysis remains a key objective in improving …

Several techniques have been introduced in the last decades for the dehydration and
release of O2 from biogenic silica (opal-A) for oxygen-isotope analysis. However, only one …

There is increasing interest in the use of biogenic silica O and Si isotope ratios to
understand climate and environmental processes. Virtually all of the fairly substantial body …

An empirical calibration for the oxygen isotope fractionation between biogenic silica and
water was determined for diatom frustules sampled from living diatom communities in the …

Few high‐latitude terrestrial records document the timing and nature of the Cenozoic
“Greenhouse” to “Icehouse” transition. Here we exploit the bulk geochemistry of marine …

Silicon isotope geochemistry is a relatively new branch of environmental change research.
Here we review the recent developments in the preparation of materials, analytical methods …

This study provides a continuous lateglacial and Holocene record of diatom silica oxygen
isotope changes (δ18ODIAT) in a subalpine lake sediment sequence obtained from the …

We present a new palaeoenvironmental record of hydrological variability in Lake Baikal,
based on re‐modelled δ18Odiatom values of diatom silica (δ18Omodelled), where the …
