Using in-situ temperature measurements to estimate saturated soil thermal properties by solving a sequence of optimization problems
in-situ temperature measurements saturated soil thermal properties optimization problems
2010/2/4
We describe an approach to find an initial approximation to the thermal properties of soil horizons. This technique approximates thermal conductivity, porosity, unfrozen water content curves in horizo...
Physiological constraints on the global distribution of Trichodesmium – effect of temperature on diazotrophy
Physiological constraints global distribution Trichodesmium diazotrophy
2010/1/14
The cyanobacterium Trichodesmium is an important link in the global nitrogen cycle due to its significant input of atmospheric nitrogen to the ocean. Attempts to incorporate Trichodesmium in ocean bio...
Temperature,pressure,and electrochemical constraints on protein speciation:Group additivity calculation of the standard molal thermodynamic properties of ionized unfolded proteins
Temperature pressure electrochemical constraints protein speciation Group additivity calculation
2010/1/13
Thermodynamic calculations can be used to quantify environmental constraints on the speciation of proteins, such as the pH and temperature dependence of ionization state, and the relative chemical sta...
The effect of temperature,salinity and growth rate on the stable hydrogen isotopic composition of long chain alkenones produced by Emiliania huxleyi and Gephyrocapsa oceanica
temperature salinity growth rate stable hydrogen isotopic composition long chain alkenones
2010/1/13
Two haptophyte algae, Emiliania huxleyi and Gephyrocapsa oceanica, were cultured at different temperatures and salinities to investigate the impact of these factors on the hydrogen isotopic compositio...
Is resistant soil organic matter more sensitive to temperature than the labile organic matter?
resistant soil organic temperature labile organic matter
2010/1/13
A recent paper by Knorr et al. (2005a) suggested that the decomposition of resistant soil organic matter is more temperature sensitive than labile organic matter. In Knorr et al.'s (2005a) model, the ...
Sea level height, sea surface temperature, and tuna yields in the Panama bight during El Niño
Sea level height sea surface temperature tuna yields the Panama bight El Niñ o
2010/1/25
Between 1988 and 1998, annual tuna landings at Buenaventura (Colombian Pacific) are correlated with the sea surface temperature in the central Equatorial Pacific (r=0.78, p<0.05) and the sea level hei...
Temperature sensitivity of decomposition in relation to soil organic matter pools:critique and outlook
Temperature sensitivity decomposition soil organic matter pools critique outlook
2010/1/12
Knorr et al. (2005) concluded that soil organic carbon pools with longer turnover times are more sensitive to temperature. We show that this conclusion is equivocal, largely dependent on their specifi...
