The Marine Carbon Cycle and Ocean Carbon Inventories

摘要: Abstract Carbon is a fundamental component of all life and its gaseous form, carbon dioxide (CO 2 ), an important atmospheric regulator Earth’s climate. Over societally relevant timescales, diverse physical, biological, chemical processes in the global ocean have very role controlling exchanges CO with atmosphere climate, given that contains roughly 60 times more than atmosphere. The complex dynamic marine cycle thus part on Earth, requiring monitoring variability understanding feedbacks to climate system. This particularly emissions human produced (anthropogenic) through fossil fuel land use changes led significant perturbations cycle. A large fraction emitted anthropogenic ( C ant ) has been will be absorbed by oceans implications for seawater chemistry, pH levels, biological communities contained within. During last few decades, quantification sink temporal evolution driver biogeochemical research. Scientific expeditions such as World Ocean Circulation Experiment/Joint Global Flux Study surveys conducted during 1990s provided data first estimates uptake oceanic . More recently, completion second survey (from 2000 2013) sufficient assess rate storage within interior ocean. From this effort, it become clear there substantial regional those physico-biogeochemical influence Here we review carbonate sampling strategies, networks required observe flux between but central focus, synthesizing summarizing available inventories chapter aimed at wider audience oceanographic community points rich literature
