This class is designed to provide the student with a global to molecular-level perspective of organic matter cycling in the oceans and marine sediments. Topics include: Organic matter (C,N,P) composition, reactivity and budgets within, and fluxes through, major ocean reservoirs; microbial recycling pathways for organic matter; models of organic matter degradation and preservation; role of anoxia in organic matter burial; relationships between dissolved and particulate (sinking and suspended) organic matter; methods for characterization of sedimentary organic matter; and application of biological markers as tools in oceanography. Both structural and isotopic aspects are covered.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Stroke is the leading cause of death worldwide. Scientists are finding that mitochondrial abnormalities play a central role in stroke. A recent study suggests that deactivating the protein SIAH2 could help mitochondria and the brain cells they power survive stroke in mice. Oxygen deprivation, which makes stroke fatal, activates SIAH2. Once activated, SIAH2 signals the breakdown of mitochondrial and cellular proteins key to survival. Aiming to curb this damage, researchers switched off the gene controlling SIAH2 formation in mouse neurons. and observed what happened after artificially inducing stroke. They found that without SIAH2, neurons suffered low damage during stroke. preserving the machinery that keeps mitochondria alive and well. Understanding how this switch operates in humans is crucial. as it could lead to drugs that target SIAH2 and help reduce the mortality of stroke..."
