Meteoritics &Planetary Science, EarlyView.Abstract Eight anhydrous interplanetary dust particles (IDPs) were analyzed for their oxygen isotopic compositions and mineralogy. They show oxygen isotopic compositions from 16O‐rich to 16O‐poor, due to mixing of different reservoirs inherited from the protosolar molecular cloud and the early solar nebula.

Stable water isotopes of snow during MOSAiC expedition
, 2022 Snow samples were collected from several locations on the main MOSAiC ice floe on weekly basis. Snow samples for measurement of stable water isotopes (δ18O, δD,) were collected in three different layers (top, middle, bottom) using a metal density cutter.

Rapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.ABSTRACT Rationale Populations of North American caribou and Eurasian reindeer (Rangifer tarandus sspp.), essential for Arctic ecosystems and human communities, are experiencing unprecedented declines due to climate change and anthropogenic pressures. While understanding their historical resilience and demographic dynamics is critical for conservation,

Paleoceanography and Paleoclimatology, Volume 41, Issue 11, November 2026.Abstract Future changes in South Asian climate are expected to amplify flooding and drought, yet the spatial and temporal variability of the South Asian monsoon (SAM) under different climate regimes remains poorly constrained. Here, we present a new marine pollen record from the Bay of Bengal (BoB), informing on the vegetation of the Ganges‐Brahmaputra

Stable isotopes in water from Lake Locknesjön, Sweden collected between 2013 and 2018
, 2022 This dataset presents measurements of stable isotopes in water (δD and δ18O) from Lake Locknesjön, Sweden. Water samples were collected between 2013 and 2018 and were taken from different depths down to 20 m in the lake, as well as from the lake's main ...
