Seasonal variation of peroxyacetylnitrate (PAN) in coastal Antarctica measured with a new instrument for the detection of sub-part per trillion mixing ratios of PAN
PAN coastal Antarctica
2008/12/18
An automated gas chromatograph with sample pre-concentration for the measurement of peroxyacetylnitrate (PAN) was constructed with a minimum detection limit below 1 pptv. This instrument was deployed ...
Observations of OH and HO2 radicals in coastal Antarctica
OH HO2 radicals coastal Antarctica
2008/12/17
OH and HO2 radical concentrations have been measured in the boundary layer of coastal Antarctica for a six-week period during the austral summer of 2005. The measurements were performed at the British...
Nitrogen and oxygen isotopic constraints on the origin of atmospheric nitrate in coastal Antarctica
Nitrogen oxygen isotopic constraint atmospheric nitrate coastal Antarctica
2008/12/8
Throughout the year 2001, aerosol samples were collected continuously for 10 to 15 days at the French Antarctic Station Dumont d'Urville (DDU) (66°40' S, l40°0' E, 40 m above mean sea level). The nitr...
Evidence for a CO increase in the SH during the 20th century based on firn air samples from Berkner Island, Antarctica
CO SH firn air samples Berkner Island Antarctica
2008/11/28
Trends of carbon monoxide (CO) for the past 100 years are reported as derived from Antarctic firn drilling expeditions. Only one of 3 campaigns provided high quality results. The trend was reconstruct...
Comparison of UV irradiance measurements at Summit, Greenland; Barrow, Alaska; and South Pole, Antarctica
UV irradiance measurement Greenland Barrow Alaska South Pole Antarctica
2008/11/17
An SUV-150B spectroradiometer for measuring solar ultraviolet (UV) irradiance was installed at Summit, Greenland, in August 2004. Here we compare the initial data from this new location with similar m...
Measurement and interpretation of gas phase formaldehyde concentrations obtained during the CHABLIS campaign in coastal Antarctica
formaldehyde CHABLIS coastal Antarctica
2008/11/13
Gas phase formaldehyde concentrations were measured during the 2004–2005 CHABLIS campaign at Halley research station, Antarctica. Data coverage span from May 2004 through to January 2005, thus capturi...
1-D-ice flow modelling at EPICA Dome C and Dome Fuji, East Antarctica
EPICA Dome C Dome Fuji East Antarctica
2008/11/6
One-dimensional (1-D) ice flow models are used to construct the age scales at the Dome C and Dome Fuji drilling sites (East Antarctica). The poorly constrained glaciological parameters at each site ar...
“EDML1”：a chronology for the EPICA deep ice core from Dronning Maud Land, Antarctica, over the last 150 000 years
EPICA Dronning Maud Land Antarctica
2008/11/5
A chronology called EDML1 has been developed for the EPICA ice core from Dronning Maud Land (EDML). EDML1 is closely interlinked with EDC3, the new chronology for the EPICA ice core from Dome-C (EDC) ...
A long-term comparison of wind and tide measurements in the upper mesosphere recorded with an imaging Doppler interferometer and SuperDARN radar at Halley, Antarctica
comparison tide measurements pper mesosphere imaging Doppler interferometer SuperDARN radar
2008/10/31
Data from a near co-located imaging Doppler interferometer (IDI) and SuperDARN radar recorded since 1996 have been analysed in a consistent manner to compare the derived mean winds and tides in the up...
On the vertical distribution of boundary layer halogens over coastal Antarctica: implications for O3, HOx, NOx and the Hg lifetime
vertical distribution boundary layer halogens coastal Antarctica Hg
2008/10/30
A one-dimensional chemical transport model has been developed to investigate the vertical gradients of bromine and iodine compounds in the Antarctic coastal boundary layer (BL). The model has been ap...
Trace element and isotopic evidence for temporal changes of the mantle sources in the South Shetland Islands, Antarctica
trace elements Sr-Nd-Pb isotopes subduction component heterogeneous mantle South Shetland Islands
2017/8/10
We present Sr-Nd-Pb isotope data from the Paleocene-Eocene volcanic rocks in King George Island, South Shetland Islands, West Antarctica. The initial isotopic ratios of the analyzed samples display li...
Modeling Tidal Current Profiles and Vertical Mixing beneath Filchner–Ronne Ice Shelf, Antarctica（图）
Modeling Tidal Current Vertical Mixing Filchner–Ronne Ice Shelf Antarctica
2008/5/28
One of the warmest water masses beneath Filchner–Ronne Ice Shelf (FRIS) is dense, high salinity shelf water (HSSW) that flows into the sub-ice-shelf cavity from the ice front and occupies the lower po...
