An overview on the variation of sea surface pCO₂ in Northern South China Sea and its managementLau, Pik-ha, 劉碧霞 January 2013 (has links)
To have better understandings of the partial pressure of carbon dioxide (pCO2)in northern South China Sea(NSCS), the pCO2readings from 1999-2012 were reviewed. Both the pCO2in NSCS and in the atmosphere also showed an increasing trends and the pCO2in NSCS varied across the seasons. There are many important processes that influenced the pCO2in NSCS, which were the rise of the temperature, biological production, seasonal upwelling, Pearl River discharge, increase in the concentration of atmospheric pCO2and the rate of calcification. These six mechanisms extend different strengths on the resultant sea surface pCO2in NSCS. The impact of induced sea water acidification on the marine phytoplankton by the high pCO2in NSCS would also be discussed. The drop of pH in the seawater would change the community of phytoplankton from diatom to dinoflagellate as a resistance to the change of pH of dinoflagellate that was better than the diatom. DMS, which was one of the climatically important gases, would also affected by the high pCO2induced seawater acidification. Hong Kong (HK) was studied as a case to estimate whether NSCS also faced the same impacts upon by the marine phytoplankton. The study showed that the diatom was relatively sensitive to the drop of pH in HK waters. The DMS producing marine phytoplankton was also affected by the drop of pH in HK waters. It was concluded that the NSCS might also face the same situation with HK. Finally, three instruments were recommended to have a better management in NSCS, namely, knowledge gaps and NSCS research priorities, valuing the NSCS as well as decision making team. Firstly, filling the knowledge gaps and NSCS research priorities aim to enhance the ability of the ocean sequestration to absorb and store the largest amount of anthropogenic CO2as possible. Afterwards, valuing the NSCS aims to protect the marine organisms, such as the phytoplankton, form the negative impacts of the decrease of ocean acidity. Last but not least, a good decision making team aims to balance the conflicts between those various options to reduce the anthropogenic CO2with ocean sequestration and impacts result from the ocean sequestration. / published_or_final_version / Environmental Management / Master / Master of Science in Environmental Management

Geological evaluation of the Eocene Latrobe Group in the offshore Gippsland Basin for CO₂ geosequestration.Root, Robert January 2007 (has links)
Title page, table of contents and abstract only. The complete thesis in print form is available from the University of Adelaide Library. / This study area for this research is characterised by a regional anticline plunging to the east-south-east with large-scale internal architecture comprising transgressive, retrogradationally stacked stratigraphy that dips gently landward and is unconformably truncated by overlying sealing units. The primary reservoir/aquifer targets for CO₂ injection are palaeo-shoreline parallel nearshore sandstone bodies characterised by high porosity and permeability and good interconnectivity. The key regional sealing unit is the Lakes Entrance Formation, which consists of mudstone and marl capable of sealing large columns of CO₂. The proposed stategy for CO₂ geosequestration is to inject CO₂ outside four-way structural closure to allow up-dip fluid migration to the north then west governed by the structure of regional sealing units. Probabilistic estimates of CO₂ capacity utilising the proposed strategy indicate that 1395-2575 Mtonnes could be sequestered. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1281480 / Thesis (Ph.D.) -- University of Adelaide, Australian School of Petroleum, 2007

Carbon encounters: cognizing the calculus of climate changeBattle, Angela January 2016 (has links)
Thesis (M.A. (Anthropology))--University of the Witwatersrand, Faculty of Humanities, School of Social Sciences, 2016. / Governments, like South Africa, are implementing carbon tax and carbon credit programs to incent businesses to lower their GHG emissions. That is not to say there are not loftier motivations in the wider world, but in this study we have mostly encountered Homo Economicus. Our observations have noted that people either want to make money or save money by way of participating in the green economy. Earth’s threatening posture is yet to change our “habitus”. The changes so far are from economic coercion and not ecological conviction. And it’s primarily prompted through the scientific community, who are understandably, the first responders to a threat with slow and mostly imperceptible reverberations. The responses of those trying to make money, involve participating in the process of carbon commodification. CERs are a new form of currency available to those able to deploy labor and capital in efforts to capture carbon molecules and prevent their creation. The looming South African carbon tax has spurred organizations to lower their emissions so as not to effect bottom-line profitability. [Taken from the conclusion. No abstract provided] / MT2017
