Jahnke, R A

Goals of this project are to develop an understanding of the processes responsible for the recycling of biogenic debris in the surface sediments of Santa Monica Basin and to quantitatively determine the rate at which dissolved chemicals exchange across the sediment-bottom water boundary. This information will provide fundamental information about organic matter decomposition and oxidation at the seafloor as well as provide a quantitative minimum estimate of the lateral input of organic matter to the deep basin from the adjacent continental shelf. We developed a preliminary organic carbon budget for the seafloor based on pore water and in situ benthic chamber flux measurements. The latter were performed with the MANOP Bottom Lander free-vehicle which was developed during the NSF sponsored Manganese Nodule Program.
