Quantification of methane fluxes and authigenic carbonate formation at cold seeps along the continental margin offshore Costa Rica: A numerical modeling approach

This thesis represent stand-alone articles which have been published or will be submitted for publication in peer-reviewed scientific journals. Each of the Chapters II, III and IV contains a separate introduction, description of methods, presentation of data, results and discussion as well as a separate reference list. Chapter II presents comprehensive results from five cold seep structures at the Costa Rican continental margin addressing the relationship between fluid advection, dissolved calcium concentrations in upward migrating fluids, and authigenic calcium carbonate precipitation. Chapter III and Chapter IV comprise the quantitative estimates of dissolved methane discharge from well-studied mud mounds and a submarine landslide at the submarine segment of the Costa Rica fore-arc margin.
