Abstract:

As a result of the increasing scarcity of freshwater resources worldwide, many countries have resorted to the use of unconventional sources, of which seawater desalination is the most significant, for meeting the supply-demand gap. However, despite the recorded advances in desalination technologies of recent decades, desalination remains a very expensive operation and operators will be greatly assisted if reliable means of predicting the costs are available to aid effective decision making during planning of new plants or the operation of existing plants. To achieve this, it is important to fu

This project aimed to characterise the organic speciation of iron in various oceanic waters associated with the New Zealand marine environment, and to examine the possible production of natural organic Fe-binding ligands by the Southern Ocean phytoplankton Phaeocystis antarctica. The location of New Zealand at the edge of the Southern Ocean provides a natural laboratory for studying ocean processes in a variety of oceanic conditions.

Abstract:

The carbon dioxide (CO2) system is the primary buffer in seawater which controls oceanic pH. Changes in the marine CO2 system affect a number of processes such as metal speciation, mineral saturation states, auditory responses in fish, and primary productivity rates. Increased atmospheric concentrations of CO2 from human activities (e.g. burning of fossil fuels, deforestation, and cement production) has led to a global decrease in surface ocean pH termed anthropogenic ocean acidification. One particular concern in response to increased oceanic CO2 is a substantial decrease in the calcium carbo

Phosphorus (P) is a requirement for biological growth, but this vital nutrient is present at low or limiting concentrations across vast areas of the global surface ocean. Inorganic polyphosphate (poly-P), a linear polymer of at least three orthophosphate units, is one component of the marine P cycle that has been relatively overlooked as compared to other P species, owing in part to a lack of routine analytical techniques that cleanly evaluate it within samples.

An analysis was conducted of 316 Stainless Steel components which exhibited an unusual degree of crevice corrosion after exposure to seawater for approximately one year. After conducting research into the possible chemical and microbiological mechanisms for the corrosion, a metallurgical and microscopic examination of the components was performed. Results of these examinations indicated that the corrosion observed was probably the result of an interaction between the Gallionella aerobic iron bacteria and the anaerobic sulfate reducing bacteria Desulfovibrio and Desulfomaculum

Abstract:

Coastal aquifers are in hydraulic contact with the sea; prolonged overpumping of groundwater can lead to inland encroachment and/or vertical up-coning of the interface (transition or mixing zone) between these regimes, causing salt contamination of freshwater aquifers. In the Mediterranean area, seawater intrusion (SWI) has sometimes become a major threat to coastal area freshwater resources, mainly due to lack of appropriate groundwater resources management. Current projections of future potential climatic scenarios further complicate the overview, because the worst considered possibilities p

Abstract:

Stable isotope ratio analyses offer a unique opportunity to obtain information about ecosystem dynamics, patterns and processes. The anthropogenic contribution to the global atmospheric CO2 rise through fossil fuel combustion, deforestation and other related human activities has changed the stable carbon isotope composition (δ13C) of the atmosphere over the past 200 years. Changes in the carbon isotopic patterns of terrestrial biosphere, lithosphere and oceans are also expected. The global ocean has been acting as a net sink for CO2 emissions and although it moderates the climate, it is curren

Abstract:

Desalination is one of the proposed methods to meet the ever increasing water demands. It can be subdivided into two broad categories, thermal based desalination and electricity based desalination. Multi-effect Distillation (MED), Multi-Stage Flashing (MSF), Membrane Distillation (MD) fall under former and Reverse Osmosis (RO), Electro-Dialysis (ED) fall under later. MD offers an attractive solution for seawater as well as brackish water distillation. It shows highly pure yields, theoretically 100% pure. The overall construction of a MD unit is way simpler than any other desalination systems.

Abstract:

Populations residing on and near the world’s coasts have become increasingly dependent on coastal groundwater for their supply of freshwater. Under the conditions of predicted climate changes, the expected rise in global sea level can adversely affect the quality and quantity of freshwater resources in coastal areas as a result of saltwater intrusion. In this study, a suite of two- and three-dimensional variable-density groundwater flow models of major coastal landforms (e.g. deltas, estuaries and small islands) has been constructed to assess the effects of sea level rise (SLR), using differen

Abstract:

This thesis describes the development of an analytical technique to measure the free copper ion concentration (pCurree) in seawater. Ion-Selective Electrode (ISE) potentiometry is the only analytical technique that can directly measure pCufree without manipulating the sample matrix, or making assumptions about the thermodynamic behaviour of the metal species. Flow analysis techniques were investigated with the aim of overcoming problems inherent in batch analysis, including sluggish response at low analyte concentrations, cross contamination from one sample to another, contamination by

碩士<br>國立中山大學<br>海洋環境學系<br>84<br>8 文主要是探討港灣變形對於港灣之擴散以及自淨能力的影響,以澎湖青灣為研究對象,以有限元素法加以分析,評估其變形後之港灣自淨能力. THE RESEARCH DESCRIBED IN THIS PAPER INVOLVES THE INFLUENCE OF THE DEFORMATION OF THE BAY ON DIFFUSION AND SELF-CLEANING ABILITY. CHING-WAN IS THE EXAMPLE TO EVALUATE THE SELF-CLEANING ABILITY AFTER DEFORMATION USING THE FINITE ELEMENT METHOD TO SIMULATE.
