  author={Markus M. Frey and Roger C. Bales and Joseph Robert McConnell},
  journal={Journal of Geophysical Research},
Author(s): Frey, MM; Bales, RC; McConnell, JR | Abstract: We report new century-scale ice core records of hydrogen peroxide (H2O2), a major atmospheric oxidant, from 23 locations across the West Antarctic Ice Sheet (WAIS) and use the spatial variability of (multi-) annual mean H2O2 concentrations in snow and firn to investigate the sensitivity of ice core H2O2 preservation to mean annual temperature and accumulation rate. In agreement with the ice-air equilibrium partitioning, H2O2 uptake in… 

Atmospheric and Ice Core Chemistry of Hydroperoxides in West Antarctica: Links to Stratospheric Ozone and Climate Variability

Current and past records of hydroperoxides in air, snow and firn of West Antarctica were investigated over 3 field seasons covering >5000 km and 24 sites. Concentrations of methylhydroperoxide (MHP),

Factors controlling variability in the oxidative capacity of the troposphere since the Last Glacial Maximum

Abstract. The oxidative capacity of past atmospheres is highly uncertain. We present here a new climate–biosphere–chemistry modeling framework to determine oxidant levels in the present and past

Ice Core Chronologies from the Antarctic Peninsula: The Palmer, Jurassic, and Rendezvous Age-Scales

In this study, we present the age scales for three Antarctic Peninsula (AP) ice cores: Palmer, Rendezvous, and Jurassic. The three cores are all intermediate-depth cores, in the 133–141 m depth

Short-Term Meteorological and Environmental Signals Recorded in a Firn Core from a High-Accumulation Site on Plateau Laclavere, Antarctic Peninsula

High-accumulation sites are crucial for understanding the patterns and mechanisms of climate and environmental change in Antarctica since they allow gaining high-resolution proxy records from firn

Understanding the drivers for the 20th century change of hydrogen peroxide in Antarctic ice‐cores

Observations and model simulations of an Antarctic ice‐core record of hydrogen peroxide during the last ∼150 years are analyzed. The observations indicate a relative increase in hydrogen peroxide by

200-year ice core bromine reconstruction at Dome C (Antarctica): observational and modelling results

Abstract. Bromine enrichment (Brenr) has been proposed as an ice core proxy for past sea-ice reconstruction. Understanding the processes that influence bromine preservation in the ice is crucial to

A doubling in snow accumulation in the western Antarctic Peninsula since 1850

We present results from a new medium depth (136 metres) ice core drilled in a high accumulation site (73.59°S, 70.36°W) on the south‐western Antarctic Peninsula during 2007. The Gomez record reveals

Recent North Greenland temperature warming and accumulation

Abstract. In a warming climate concise knowledge of the mass balance of the Greenland ice sheet is of utter importance. Speculations that current warming will increase the snow accumulation and

Atmospheric nitric oxide and ozone at the WAIS Divide deep coring site: a discussion of local sources and transport in West Antarctica

Abstract. The first measurements of atmospheric nitric oxide (NO) along with observations of ozone (O3), hydroperoxides (H2O2 and MHP) and snow nitrate (NO3–) on the West Antarctic Ice Sheet (WAIS)

Supplementary material to "NEEM to EastGRIP Traverse – spatial variability, seasonality, extreme events and trends in common ice core proxies over the past decades"

Abstract. Greenland ice cores provide information about past climate. However, the number of firn and ice cores from Greenland are limited and thus the spatial variability of the chemical impurities



Sensitivity of hydrogen peroxide (H2O2) and formaldehyde (HCHO) preservation in snow to changing environmental conditions: Implications for ice core records

[1] Sensitivity studies with physically based numerical air–snow–firn transfer models for formaldehyde (HCHO) and hydrogen peroxide (H2O2) show that even though nonlinear processes determine the

Climate variability in West Antarctica derived from annual accumulation-rate records from ITASE firn/ice cores

Abstract Thirteen annually resolved accumulation-rate records covering the last ~200 years from the Pine Island–Thwaites and Ross drainage systems and the South Pole are used to examine climate

Atmosphere-snow transfer function for H2O2: Microphysical considerations

H2O2 analyses of polar ice cores show an increase in concentration from 200 years to the present. In order to quantitatively relate the observed trend in the ice to atmospheric levels, the

Glacio-chemical study spanning the past 2 kyr on three ice cores from Dronning Maud Land, Antarctica: 1. Annually resolved accumulation rates

For the first time, annually resolved accumulation rates have been determined in central Antarctica by means of counting seasonal signals of ammonium, calcium, and sodium. All records, obtained from

Seasonal Variations in Hydrogen Peroxide in Polar Ice Cores

Hydrogen peroxide is present in polar snow and ice in remarkably high concentrations. With values up to 300 ppb, H2O2 is one of the most concentrated impurities in polar ice. We present a continuous

Hydrogen peroxide (H2O2) contributes to the atmospheres oxidizing capacity, which determinesthe lifetime of atmospheric trace species. Measured bidirectional summertime H2O2 fluxes fromthe snowpack

Glaciochemistry of polar ice cores: A review

Human activities have already modified the chemical composition of the natural atmosphere even in very remote regions of the world. The study of chemical parameters stored in solid precipitation and

Glaciological and climatic significance of Hercules Dome, Antarctica: An optimal site for deep ice core drilling

[1] We present glaciological and climatological characteristics of Hercules Dome, Antarctica (86°S, 105°W), which demonstrate its potential as a deep ice core site. Annual layering in δD ratios from
