Temporal and spatial changes in organic carbon sequestration in shelf sediments along a fl — NSF Award to Oregon State University

Rivers transport large amounts of sediment and organic carbon (OC) from land to the ocean, with much of this material deposited on the continental shelf. These shallow environments are therefore important for OC burial and storage. However, knowing the amount and long-term stability of this OC is challenging because of

AbstractRivers transport large amounts of sediment and organic carbon (OC) from land to the ocean, with much of this material deposited on the continental shelf. These shallow environments are therefore important for OC burial and storage. However, knowing the amount and long-term stability of this OC is challenging because of changing conditions in coastal systems. This project will revisit a shelf region off the Umpqua River in central Oregon that was sampled in 2009 to see whether sedimentation and O
