Kilo Nalu:Physical/Biogeochemical Dynamics Above and Within Permeable Sediments
Kilo Nalu Physical/Biogeochemical Dynamics Permeable Sediments
2015/7/22
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 effect of groundwater advection on salinity in pore waters of permeable sediments
groundwater advection salinity in pore waters permeable sediments
2014/4/18
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...
Denitrification in shallow, sublittoral Gulf of Mexico permeable sediments
Denitrification in shallow sublittoral Gulf Mexico permeable sediments
2014/4/16
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...
Rates of carbonate dissolution in permeable sediments estimated from pore-water profiles: The role of sea grasses
carbonate dissolution permeable sediments estimated pore-water profiles sea grasses
2014/4/21
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...
Bioturbation and bioirrigation extend the open exchange regions in permeable sediments
Bioturbation bioirrigation extend exchange regions
2014/4/22
Large-scale experimental exclusion of lugworms (Arenicola marina) from 400 m2
intertidal fine sand revealed
significant effects of their bioturbation and bioirrigation on sediment characteristics, b...
Bioirrigation in permeable sediments: Advective pore-water transport induced by burrow ventilation
permeable sediments Advective pore-water transport induced
2014/4/23
The physical mechanism that drives bioirrigation is strongly dependent on the permeability of the sediment. We
advance two mechanisms, each described by a corresponding microenvironment model. In mud...
Oxygen dynamics in permeable sediments with wave-driven pore water exchange
Oxygen dynamics permeable sediments wave-driven pore water exchange
2014/5/14
The effects of advective pore water exchange driven by shallow water waves on the oxygen distribution in a permeable (k = 3.3 x 10-12 to 4.9 x 10-11 m2) natural sediment were studied with a planar oxy...
