Organic Carbon and Organic Matter Levels in Sediments of the Strait of Hormoz, the Persian Gulf
Total organic carbon has a major influence on both the chemical and biological processesthat take place in sediments. Algal bloom is one of the organic carbon levels in aquatic ecosystems. In 2009 algal bloom occurred in the Hormozgan province and prolonged for months, which finally setteled down in 2010. In this study the variations of total organic carbon (TOC), organic matter (TOM) and tot...
متن کاملEnhanced chemical weathering and organic carbon burial as environmental recovery factors of the OAE2; a case study in the Koppeh-Dagh Basin (NE Iran)
A late Cenomanian-early Turonian interval (Hamam-ghaleh section) adjusted with the transition of Aitamir and Abderaz formations has been investigated in the east of Koppeh-Dagh Basin to examine environmental perturbations related to the oceanic anoxic event 2. The dark shale of the upper Aitamir Formation indicate higher organic matter concentrations especially in the two intervals at the end o...
متن کاملExperimental Evidence for Abiotic Sulfurization of Marine Dissolved Organic Matter
Dissolved organic sulfur (DOS) is the largest pool of organic sulfur in the oceans, and as such it is an important component of the global sulfur cycle. DOS in the ocean is resistant against microbial degradation and turns over on a millennium time scale. However, sources and mechanisms behind its stability are largely unknown. Here, we hypothesize that in sulfate-reducing sediments sulfur is a...
