methods for estimating the age of the universe and the corresponding
uncertainties are comparatively studied in the present paper.We are...
Rapid reorganization in ocean biogeochemistry off Peru towards the end of the Little Ice Age
Rapid reorganization ocean biogeochemistry Peru Little Ice Age
2010/1/20
Climate and ocean ecosystem variability has been well recognized during the twentieth century but it is unclear if modern ocean biogeochemistry is susceptible to the large, abrupt shifts that characte...
Effect of Season and Age on the Ovarian Size and Activity of One-Humped Camel (Camelus dromedarius)
Ovarian Size Activity Season Age Female Camel
2016/5/3
In this project, ovarian size and activity during the peak (November-April) and the low (May-October) breeding seasons in young and adult camels were studied. Ovaries of 92 camels (Camelus dromedarius...
Age, Growth, and Gonadosomatic Index (GSI) of Mediterranean Horse Mackerel (Trachurus mediterraneus Steindachner, 1868) in the Eastern Black Sea
Mediterranean horse mackerel T. mediterraneus Eastern Black Sea age growth gonadosomatic index (GSI)
2010/3/25
The aim of this study was to calculate the basic population parameters of Trachurus mediterraneus off the coast of the Eastern Black Sea. Average total length was estimated as 13.52 ± 1.884 cm for the...
Comparison of Rainfall-Runoff Characteristics in Forested Catchments Underlain by Granitic and Sedimentary Rock with Various Forest Age
rainfall-runoff Granitic Sedimentary Rock Various Forest Age
2009/4/13
This study examines rainfall-runoff characteristics of catchments underlain by granitic and sedimentary rock. Differences in bedrock geology and forest age for sedimentary rock catchments were conside...
Assessing the Relationship between Air Mass Age and Summer Ozone Episodes Based on Photochemical Indices
Ozone Aerosol Aging Backward trajectory Conversion ratio Photochemical index
2016/3/25
Although pollutant sources are usually in urban and industrialized areas, poor air quality is
frequently encountered in downwind rural areas. This study utilized a tethered balloon to measure the
po...
THE BRONZE-AGE ASTRONOMICAL FINDS IN THE TERRITORY OF SERBIA
BRONZE-AGE ASTRONOMICAL TERRITORY OF SERBIA calendar records
2009/3/13
In the present paper it is shown that among the archeological
finds at Vatin, some 50 km north-east of Belgrade, there are primeval astronomical
instruments: gnomon, metron along with the calendar r...
Transport mechanisms for synoptic, seasonal and interannual SF6 variations and“age”of air in troposphere
Transport mechanisms synoptic seasonal interannual SF6 variations troposphere
2009/3/13
We use an atmospheric general circulation model (AGCM) driven chemistry-transport model (ACTM) to simulate the evolution of sulfur hexafluoride (SF6) in the troposphere. The model results are compared...

Wind Shifts May Stir CO2 From Antarctic Depths--Releases May Have Speeded End of Last Ice Age—And Could Act Again(图)
Wind Shifts CO2 Antarctic Depths Last Ice Age
2009/12/10
Natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age--and could be repeated as manmade warming pr...
Model calculations of the age of firn air across the Antarctic continent
Model calculations firn air Antarctic continent
2009/3/4
The age of firn air in Antarctica at pore close-off depth is only known for a few specific sites where firn air has been sampled for analyses. We present a model that calculates the age of firn air at...
Stratospheric age of air computed with trajectories based on various 3D-Var and 4D-Var data sets
Stratospheric age trajectories 3D-Var 4D-Var
2009/1/23
The age of stratospheric air is computed with a trajectory model, using ECMWF ERA-40 3D-Var and operational 4D-Var winds. Analysis as well as forecast data are used. In the latter case successive fore...
The Age of Water and Ventilation Timescales in a Global Ocean Model
Ventilation Timescales Global Ocean Model North Atlantic Deep Water
2008/12/12
The age of water in the World Ocean is studied using a passive age tracer introduced into a global ocean model. Additional information is derived from a transient “dye” tracer that tracks the time-dep...

New constraints on the gas age-ice age difference along the EPICA ice cores, 0–50 kyr
age-ice EPICA ice cores
2008/11/5
Gas is trapped in polar ice sheets at ~50–120 m below the surface and is therefore younger than the surrounding ice. Firn densification models are used to evaluate this ice age-gas age difference (Δag...
