Dynamic coupling of volcanic CO2 flow and wind at the Horseshoe Lake tree kill, Mammoth Mountain, California

[1] We investigate spatio-temporal relationships between soil CO2 flux (FCO2), meteorological variables, and topography over a ten-day period (09/12/2006 to 09/21/ 2006) at the Horseshoe Lake tree kill, Mammoth Mountain, CA. Total CO2 discharge varied from 16 to 52 t d !1, suggesting a decline in CO2 emissions over decadal timescales. We observed systematic changes in FCO2 in space and time in ...

Response of Lodgepole Pine Growth to Co2 Degassing at Mammoth Mountain, California

We conducted dendroclimatic and stable isotope analyses of lodgepole pines (Pinus contorta) located in high-mortality sites at Mammoth Mountain (California, USA) to test for tree responses to magmatic degassing. Existing climatic and tree-ring data from nearby Yellowstone National Park were used for comparison. Sampled trees were scarcely sensitive to climate, and their growth showed an overall...

Six-week time series of eddy covariance CO2 flux at Mammoth Mountain, California: Performance evaluation and role of meteorological forcing

CO2 and heat fluxes were measured over a six-week period (09/08/2006 to 10/24/2006) by the eddy covariance (EC) technique at the Horseshoe Lake tree kill (HLTK), Mammoth Mountain, CA, a site with complex terrain and high, spatially heterogeneous CO2 emission rates. EC CO2 fluxes ranged from 218 to 3500 g m −2 d (mean=1346 g m d). Using footprint modeling, EC CO2 fluxes were compared to CO2 flux...

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
