“…Teng et al (22), presented a theory of CO 2 -gas solubility in seawater, and in their paper they investigated the CO 2 -water binary system and CO 2 -gas solubility in seawater. They carried out a complete mathematical derivation of the CO 2 -water binary system, and CO 2 -gas solubility in seawater, and they have obtained an expression to calculate the solubility coefficient for the CO 2 -water binary system and CO 2 -gas solubility in seawater similar to that obtained by (30).…”

The two main methods of removing salt from ocean water currently in use for large scale applications are: distillation using thermal desalination and membrane reverse osmosis separation. A detailed knowledge of the CO 2 solubility in the seawater at the conditions prevailing in the system is required for the modeling of CO 2 release in the multi-stage flash distillers. The measurement of the solubility of CO 2 in pure water has been extensively studied in the literature, whereas there is a lack of saline solutions studies. Several studies have investigated the solubility of CO 2 in seawater under different temperatures and pressures without covering the conditions that prevailed in the desalination plants for example low pressures and high temperatures. The gas solubility can be theoretically estimated by considering the ionic strength and the salting-out parameter in the low-pressure regime, i.e., near atmospheric pressure. The measurements of gas solubility can be made as a function of the seawater temperature and salinity at low pressure where effect of pressure can be considered negligible. Alkaline scale formation causes fouling in the MSF plants and it is known that the rate of formation of calcium carbonate and magnesium hydroxide in seawater depends on a number of parameters such as temperature, pH, concentration of bicarbonate ions, rate of CO 2 release, concentration of Ca 2þ and Mg 2þ ions, and total dissolved solids. This review shows an overview of the carbon dioxide solubility in the high concentrated saline water, carbonate equilibriums in the seawater and the various correlations used to characterize the CO 2 -seawater system.

“…The solubility pump refers to the relationship between the solubility of CO 2 in water and temperature; in cold water CO 2 is more soluble [129]. Temperature and salinity circulation in the ocean can carry CO 2 from the surface to the depths, effectively sinking CO 2 .…”

Thanks first goes to my family and friends for their support and willingness to entertain hours of conversation about robot boats and marine methane. I especially wish to acknowledge my parents for the freedom they provided me throughout my life to explore my interests, ultimately enabling me to become the independent (and quirky) person I am today. I also sincerely thank my partner, Bill, for his enthusiasm about my work, ability to engage in thoughtful conversations about robotics, and his enduring ability to make me laugh when the going gets tough. To my advisers, Anna Michel and Nicholas Roy, I extend sincere gratitude for their mentorship and insight throughout my work. I recognize the fortune I have to work with two incredible professionals in two unique fields, and the opportunities for field work and learning this has afforded. Additionally, working with their labs, WHOI DSL Michel Lab and MIT CSAIL RRG, has been a pleasure. Being surrounded by thoughtful and creative minds everyday is a privilege; and I'm especially thankful to count these individuals among my friends. I particularly thank my research collaborators Dr.Cara Manning, Dr.David Nicholson, Dr.Yogesh Girdhar, Genevieve Flaspohler, and Kevin Manganini for their insight, patience, support, and positive attitudes throughout our work together. They have taught me so much about how to be a good scientist, engineer, and communicator. As I hit this milestone on my way towards earning a PhD, I look forward to what the future has in store. I would like to dedicate this thesis to my parents, Matthew and Elizabeth Preston, to whom I owe my intellectual curiosity, confidence, and perseverance.

“…Many scientists have published values for the solubility of CO 2 in seawater, see for instance Murray and Riley, 1971 [95], Weiss, 1974 [139], and Teng et al, 1996 [128]. As saturated seawater is cooled down, some CO 2 is precipitated from the saturated seawater as CO 2 hydrate [8].…”

“…In situations with relative stable pressure and temperature conditions, the solubilities in Equation (3.14) can be considered as fixed values. For deep sea cases without hydrate, solubilities based on the model by Teng et al, 1996 [128] (χ gs =0.0676) can be used, and for cases with hydrate the experimental value from Aya et al, 1997 [8] (χ gs h =0.0476) based on a pressure of 30 MPa and 3.1 o C can be used.…”

The main focus of this thesis is the effect of topographic features on the transport of tracers in the bottom boundary layer. The thesis covers two specific studies; transport of CO 2 which is directly introduced into the deep ocean and transport of passive food particles to cold-water corals. The study is performed using Reynolds Averaged Navier Stokes Models (RANS) on a relative small scale with horizontal grid sizes ranging from 75 meter to approximately 1 meter. A general background for the study is given in Part I, and Part II consists of the four included papers. Papers included in this thesis The following papers are included in this thesis; Paper A: Dissolution of a CO 2 lake, modeled by using an advanced vertical turbulence mixing scheme, L.
