These records confirm that the CO2 concentration varied between 260 and 280 ppmv in the Holocene as measured in the Taylor Dome ice core. However, there are differences in the CO2 records most likely caused by mismatches in timescales. Matching the Taylor Dome timescale to the Dome C timescale by synchronization of CO2 indicates that the accumulation rate at Taylor Dome increased through the Holocene by a factor of two and bears little resemblance to the stable isotope record used as a proxy for temperature. This result shows that different locations experienced substantially different accumulation changes, and casts doubt on the often-used assumption that accumulation rate scales with the saturation vapor pressure as a function of temperature, at least for coastal locations. #-------------------- # Publication # Authors: Flückiger, J., E.

Little is known, however, about possible N2O variations during the more stable climate of the present interglacial (Holocene) spanning the last 11 thousand years. Here we fill this gap with a high-resolution N2O record measured along the European Project for Ice Coring in Antarctica (EPICA) Dome C Antarctic ice core. On the same ice we obtained high-resolution methane and carbon dioxide records. This provides the unique opportunity to compare variations of the three most important greenhouse gases (after water vapor) without any uncertainty in their relative timing. The CO2 and CH4 records are in good agreement with previous measurements on other ice cores. The N2O concentration started to decrease in the early Holocene and reached minimum values around 8 ka (<260 ppbv) before a slow increase to its preindustrial concentration of ~265 ppbv. #-------------------- # Publication # Authors: Monnin, E., A.

The close correlation between CO2 concentration and Antarctic temperature indicates that the Southern Ocean played an important role in causing the CO2 increase. However, the similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations. #-------------------- # Publication # Authors: Schwander, J., J.

The age of volcanic eruptions, the end of the Younger Dryas event, and the estimated depth and age of elevated 10Be, about 41 kyr ago were used to calibrate the model parameters. The uncertainty of EDC1 is estimated to ±10 yr for 0 to 700 yr BP, up to ±200 yr back to 10 kyr BP, and up to ±2 kyr back to 41 kyr BP. The age of the air in the bubbles is calculated with a firn densification model. In the Holocene the air is about 2000 yr younger than the ice and about 5500 yr during the last glacial maximum. #-------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #-------------------- # Site_Information # Site_Name: Taylor Dome # Location: Antarctica # Northernmost_Latitude: -77.78 # Southernmost_Latitude: -77.78 # Easternmost_Longitude: 158.72 # Westernmost_Longitude: 158.72 # Elevation_m: 2365 #-------------------- # Data_Collection # Collection_Name: Taylor Gas Sync Monnin2004 # Earliest_Year: 11224 # Most_Recent_Year: 94 # Time_Unit: cal yr BP # Core_Length_m: # Parameter_Keywords: age control # Notes: #-------------------- # Chronology_Information # Chronology: # #-------------------- # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/PaST-thesaurus/SKOS/past-thesaurus-v1.0.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Variables format: Short_name what,material,error,units,seasonality,data_type,detail,method,data_format,additional_information # ## depth_m depth,,,meter,,ice cores,,,N, ## gas_ageBP gas age,,,calendar year before present,,ice cores,,,N,synchronized using CO2 to EDC1 time scale from Schwander et al. 2001 # #-------------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: depth_m gas_ageBP 86 94.5 90 149.2 94 205.2 98 260.9 102 316.2 106 372 110 427.9 114 483.7 118 540.1 122 598.1 126 658.4 130 722.7 134 790.3 138 860.5 142.1 929.8 146.1 995.5 150.1 1058.1 154.1 1119.4 158.1 1180.7 162.1 1243.2 166.1 1308 170.1 1377.6 174.1 1454.7 178.1 1539.6 182.1 1633 186.1 1731.9 190.1 1835.6 194.1 1940 198.1 2045.1 202.1 2150 206.1 2254.5 210.1 2361.9 214.1 2475.5 218.1 2594.6 222.1 2715.6 226.1 2835.7 230.1 2954.2 234.1 3070.8 238.1 3188.2 242.1 3308 246.1 3429.6 250.1 3550.6 254.2 3670.1 258.2 3787.9 262.2 3905.9 266.2 4026.1 270.2 4153.3 274.2 4295.3 278.2 4454.1 282.2 4629.4 286.2 4814 290.2 4998.6 294.2 5174.8 298.2 5342.8 302.2 5507.9 306.2 5674.9 310.2 5846.8 314.2 6031.1 318.2 6242.5 322.2 6502 326.2 6830.5 330.2 7238.7 334.2 7710.2 338.2 8215.9 342.2 8735.9 346.2 9226.8 350.2 9762.8 354.2 10289.2 358.2 10720.5 362.3 11224.1
