(2013-04-29)A flux measurement setup was established at a communications tower north of downtown Houston, Texas, to measure energy and trace gas fluxes from a variety of emission sources in the urban surface layer. The first part of ...
-
(Texas A&M University. Libraries, 1976)Stable carbon isotope fractionations by seventeen species of marine phytoplankton, representing the classes of Bacillariophyceae, Chlorophyceae, Prasinophyceae, Chrysophyceae, Haptophyceae and Dinophyceae, have been ...
-
(2017-05-05)The Southern Great Plains has potential to produce bioenergy crops on a large scale. However, the potential environmental impact of large scale production of bioenergy crops on carbon, evapotranspiration (ET) and energy ...
-
(2015-08-05)Government regulations on emission standards and constantly fluctuating fuel availability and prices have led to the need of more readily usable and available models for power generating combustors. A common, versatile, ...
-
(Texas A&M University. Libraries, 1972)A general radiocarbon survey was conducted for the Gulf of Mexico and adjacent areas. A wide variety of samples was run in an effort to determine current levels of radiocarbon activity in Gulf coast rivers, the atmosphere, ...
-
(2023-04-21)The terrestrial carbon, energy, and water cycles are coupled through soil moisture (SM) and evapotranspiration (ET) control on gross primary productivity (GPP) thus controlling the biosphere, land-atmosphere interactions, ...
-
(2014-06-03)The fate of carbon in the ocean determines both the amount of CO_(2) that can be sequestered and the amount of sustainable biomass. Compartmentalization into new and regenerated production allows a first order estimate of ...
-
(2012-07-16)Nearly 550 samples of fine grained carbonates, collected every 0.5 to 1.0 m from the Bloom Member of the Snaky Canyon Formation at Gallagher Peak, Idaho, were analyzed to determine the high-resolution carbon isotope ...
-
(2010-07-14)The sustainability of the Texas agricultural and timber sectors is measured using the ratio of human appropriation of net primary productivity (HANPP) to available net primary productivity (NPP) on a county-by-county basis ...
-
(Texas A&M University. Libraries, 1976)The kinetics of formation and isotopic composition of methane generated by pyrolysis at 500°C from coal samples of different ranks, crude oil fractions and some pure organic compounds have been used to study the mechanisms ...
-
(2015-08-13)Nitrogen, phosphorous and carbon are naturally occurring nutrients that are essential for all organic life. However, the water quality of many water bodies is negatively affected by high concentrations of these nutrients. ...
-
(2020-04-14)Peatlands have been important terrestrial carbon reservoirs throughout the Holocene, yet whether these ecosystems will become stronger carbon sinks in the future remains debated. While surface peat layers have a greater ...
-
(2021-10-26)Bio-derived carbon-based-supercapacitor electrodes present an economical solution as sustainable sources for energy storage. Serious knowledge gaps exist for bio-derived carbon electrodes in terms of causes of largely ...
-
(2020-05-20)Prokaryotes make up the majority of the biomass in sediment, where they play a role in cycling organic carbon and regulate the fluctuation of organic matter. Studies of abundance, genomic composition, and ecological roles ...
