Investigation of hypothesized anaerobic stabilization mechanisms in biological phosphorus removal systems
… the need to quantify the clarifier OUR, the Boundary Exchange AnS determination method developed in this study afforded a major advantage over earlier methods. Non-zero AnS was shown to be a statistically significant, reproducible phenomenon. Carbon, oxygen, and sulfur were identified as the …

Do Muds Sort? Experimental Test of a Hypothesis Key to Understanding Marine Bottom Currents
Accumulations of fine sediments in deep-ocean contourites form a sedimentary record that has been hypothesized to be directly related to bottom-current behavior. This is known as the 'sortable silt' hypothesis and states that the non-cohesive, coarse silt in the 10 to 63 µm size range within a …

Marine cycling of neodymium in the South Atlantic and the Southern Oceans
… the Southern Ocean) to investigate the possible boundary processes. A suite of measurements made on seawater, porewater, and marine sediment show that boundary exchange is the prevailing process modifying porewater and bottom water by shifting their Nd isotopic ratios to more radiogenic values …
