Certain low-molecular-weight gases, such as methane, ethane, and carbon dioxide, can combine with water to form ice-like substances at high pressure or low temperature. These compounds, commonly calle...
The Kilo Nalu Nearshore Reef Observatory is a cabled physical-biogeochemical ocean observing system along the south coast of Oahu, Hawaii. Real-time observations began with the deployment of a range o...
The box corer is a relatively new tool used in the geotechnical community for collection of soft seabed sediments. Miniature full flow and model pipeline probes were developed as tools to characterize...
Laboratory incubations with river-bed sediment collected from riffles and pools were used to quantify potential pathways of dissimilatory nitrate reduction in the hyporheic zone of a groundwater-fed r...
Measurements of the upward advection and pore-water profiles of salinitywere made at three coastal settings(the Venice Lagoon, Italy; Jamaica Bay, New York; and Mattituck, New York). Coincident measur...
The intensity and pathways of mineralization of sedimentary organic matter were investigated in eutrophic Lake Zug, Switzerland. In a depth transect (25–180 m) from oxic to anoxic bottom water we reco...
We compared the burial efficiency of organic carbon (buried OC : depositedOC) in a diverse set of 27 different sediments from 11 lakes, focusing on the potential effects of organic matter source, oxyg...
We present a detailed study of the biogeochemical factors controlling mercury (Hg) distribution, methylmercury (MeHg) production, and MeHg efflux in sediments of the mid-Atlantic continental shelf an...
We employed real-time pressure recording and high temporal resolution two-dimensional oxygen imaging to characterize the porewater bioadvection related to hydraulic activities of Arenicola marina, a w...
The composition and production of carbohydrates (mannose, rhamnose, fucose, galactose, glucose, and xylose) and their transfer among sediment compartments (microphytobenthos [MPB], bacteria, and detri...
The effects of increased nitrogen loading on denitrification and dissimilatory nitrate reduction to ammonium (DNRA) in marsh sediments were studied in permanently submerged subtidal creek sediments a...
We examined nitrogen cycling over a 1-yr period in shallow, sandy sediments at two contrasting sites near a barrier island in the northeastern Gulf of Mexico, and we provide here the direct determinat...
The vertical color transition from brown to gray-green in marine sediments is linked to the Fe redox boundary and is commonly used as a proxy for biogeochemical state. We combine time-lapse sediment ...
In this study we estimate sediment carbonate dissolution rates for sandy sea grass sediments on the Bahamas Bank using an inverse pore-water advection/diffusion/reaction model constrained by field obs...
Dissolved oxygen (DO) concentrations were quantified near the sediment–water interface to evaluate DO transfer to sediments in a laboratory recirculating flume and open channel under varying fluid-flo...
