Towards a greater understanding of pattern, scale and process in marine benthic systems: a picture is worth a thousand worms (2003, background): “These techniques have shown that the horizontal and vertical oxygen concentration in marine sediments and microbial mats varies at a mm and Am scale, respectively, with O2 micro-niches and ‘hot spots’ of intense production and consumption relating to infaunal activity and microphytobenthic photosynt”
Biogeochemical responses to mass coral spawning at the Great Barrier Reef: Effects on respiration and primary production (2008, methodology): “Microsensor studies have revealed that respiration in light-exposed benthic phototrophic communities exceed nighttime respiration by a factor of at least 1.4–1.8 (Fenchel and Glud 2000 and references therein).”
Small‐scale spatial and temporal variability in coastal benthic O2 dynamics: Effects of fauna activity (2004, background): “Light stimulated respiration in benthic communities is a well-documented fact (e.g., Epping and Jørgensen 1996), and measurements performed at the same site as the present study documented a light-enhanced respiration of at most 60% in diatom covered sediment patches (Fenchel and Glud 2000).”
Impacts of longline mussel farming on oxygen and nitrogen dynamics and biological communities of coastal sediments (2003, background): “Additionally, photosynthesis changes oxygen conditions and influences mineralization processes within the sediments (Rysgaard et al., 1994; Fenchel and Glud, 2000).”
Virus and bacteria dynamics of a coastal sediment: Implication for benthic carbon cycling (2004, background): “…perturbate the sediment, resuspension events redistribute material, sedimentation of carbon-enriched aggregates creates short-lived hotspots, and benthic primary production locally changes the redox conditions and the nutrient concentration (e.g., Fenchel and Glud 2000; Wenzhöfer and Glud 2004).”
Temperature effects on respiration and photosynthesis in three diatom-dominated benthic communities (2004, background): “…of intact benthic microbial communities is complicated by the simultaneous impact on physical and chemical controls, and by the fact that benthic microbial communities host a complex phototrophic and heterotrophic diversity (Revsbech et al. 1981, Epping & Jørgensen 1996, Fenchel & Glud 2000).”
Oxic microzones and radial oxygen loss from roots of Zostera marina (2005, background): “…oxygen production of 8 to 13.5 mmol O2 m–2 h–1, and causes an effective transport of oxygen down into the deeper sediment of 2.8 to 4.7 mmol O2 m–2 h–1 (Fenchel & Glud 2000) indicating that oxygen leakage from Z. marina roots makes but a minor contribution to the total oxygen content of the…”
Benthic biogeochemistry: state of the art technologies and guidelines for the future of in situ survey (2003, background): “The recent introduction of planar optodes to the study of aquatic biology allows for two-dimensional quantification of the distribution and exchange of oxygen in marine sediments (Glud et al., 1996a,b, 1999b; Fenchel and Glud, 2000).”
