Deuterium excess record from a small Arctic ice cap [PDF]

Journal of Geophysical Research: Atmospheres, 2008
In this paper we present a deuterium excess (d) record from an ice core drilled on a small ice cap in Svalbard in 1997. The core site is located at Lomonosovfonna at 1255 m asl, and the analyzed time series spans the period 1400–1990 A.D. The record shows pronounced multidecadal to centennial‐scale variations coherent with sea surface temperature ...

The GRIP deuterium-excess record

Quaternary Science Reviews, 2007
Abstract Ice cores from Greenland and Antarctica are ideal archives for retrieving long time series of deuterium-excess ( d = δ D — 8 * δ 18 O ), a parameter influenced by conditions prevailing in the oceanic regions which provide moisture for polar snow.

Quantifying recycled moisture fraction in precipitation of an arid region using deuterium excess [PDF]

Tellus: Series B, Chemical and Physical Meteorology, 2013
Terrestrial moisture recycling by evapotranspiration has recently been recognised as an important source of precipitation that can be characterised by its isotopic composition.

Seasonal Deuterium Excess Variations of Precipitation at Summit, Greenland, and their Climatological Significance [PDF]

Journal of Geophysical Research D: Atmospheres, 2019
Abstract The hydrogen and oxygen isotopic composition of ice cores from Summit, Greenland, has provided invaluable information about variations in past climate. However, interpretations of these isotopic data have been made despite a paucity of direct isotopic studies of Summit precipitation. We provide insight to such interpretations

Exploring the Deuterium Excess of Cretaceous Arctic Paleoprecipitation Using Stable Isotope Composition of Clay Minerals from the Prince Creek Formation (Maastrichtian) in Northern Alaska

Geosciences, 2023
We report estimated stable isotope compositions of Artic paleoprecipitation using phyllosilicates sampled from three paleosols and two bentonites in the Prince Creek Formation (Maastrichtian) in northern Alaska.

Stable Isotope Composition of Water Vapor and Weather in Typhoon Process Relationships: A Case Study of Typhoon Soudelor (1513)

Redai dili, 2022
The stable hydrogen and oxygen isotopic composition of precipitation or water vapor not only shows the response to climate change on different time scales, but also has a strong relationship with typhoon extreme weather events.

The isotopic composition of water vapour and precipitation in Ivittuut, southern Greenland [PDF]

Atmospheric Chemistry and Physics, 2014
Since September 2011, a wavelength-scanned cavity ring-down spectroscopy analyser has been remotely operated in Ivittuut, southern Greenland, providing the first record of surface water vapour isotopic composition based on continuous measurements in ...

Monitoring Characteristics of Hydrogen and Oxygen Isotopes in Precipitation of Nanjing

应用气象学报, 2022
With the climate change, extreme precipitation events become more and more frequent. It is particularly important to explore the characteristics of different precipitation types for the study of local precipitation process and water cycle.

Ice‐age variability from the Vostok deuterium and deuterium excess records [PDF]

Journal of Geophysical Research: Atmospheres, 2001
The four climatic cycles obtained from the Vostok ice core offer a unique opportunity to study the high‐frequency paleoclimatic variability, i.e., on time scales smaller than 15 kyr. We focused our study on the deuterium (δD) and deuterium excess (d) records, which are proxies for local temperature and remote evaporation source temperature and hence ...

Stable water isotopes of precipitation and firn cores from the northern Antarctic Peninsula region as a proxy for climate reconstruction [PDF]

The Cryosphere, 2012
In order to investigate the climate variability in the northern Antarctic Peninsula region, this paper focuses on the relationship between stable isotope content of precipitation and firn, and main meteorological variables (air temperature, relative ...
