Fluorescence imaging techniques involving chemical sensors are essential tools in many
fields of science and technology because they enable the visualization of parameters which …

Advective flows rapidly transport water, solutes, and particles into and out of permeable
sand beds and significantly affects the biogeochemistry of coastal environments. In this …

Aquatic eddy covariance (AEC) is increasingly being used to study benthic oxygen (O2) flux
dynamics, organic carbon cycling, and ecosystem health in marine and freshwater …

Benthic O2 availability regulates many important biogeochemical processes and has crucial
implications for the biology and ecology of benthic communities. Further, the benthic O2 …

The sandy sediments that blanket the inner shelf are situated in a zone where nutrient input
from land and strong mixing produce maximum primary production and tight coupling …

The microbial community composition and biogeochemical dynamics of coastal permeable
(sand) sediments differs from cohesive (mud) sediments. Tide-and wave-driven …

The hyporheic zone is an ecotone connecting the stream and groundwater ecosystem that
plays a significant role for stream biogeochemistry. Water exchange across the stream …

The increasing appreciation of the small-scale (sub-mm) heterogeneity of biogeochemical
processes in sediments, wetlands and soils has led to the development of several methods …

A simple, high resolution colormetric planar optode imaging approach is presented. The
approach is simple and inexpensive yet versatile, and can be used to study the two …

The oxygen dynamics in the rhizosphere of Zostera marina was studied by use of planar
optodes. Oxygen leakage to the rhizosphere was restricted to the root tip and extended only …
