Hydrocarbon influence on denitrification in bioturbated Mediterranean coastal sediments [PDF]

, 1997
An in situ experiment has been carried out inbioturbated Mediterranean coastal marine sediments (Gulfof Fos) in order to study the influence of hydrocarbons ondenitrification after 1, 4 and 6 months. In theabsence of hydrocarbons in the control sediments,

Influence of Chironomus riparius (Diptera, Chironomidae) and Tubifex tubifex (Annelida, Oligochaeta) on oxygen uptake by sediments. Consequences of uranium contamination [PDF]

, 2009
The diffusive oxygen uptake (DOU) of sediments inhabited by Chironomus riparius and Tubifex tubifex was investigated using a planar oxygen optode device, and complemented by measurements of bioturbation activity.

Burial and reactivity of sedimentary microalgal lipids in bioturbated Mediterranean coastal sediments [PDF]

, 2003
The fate of microalgal lipid biomarkers in marine coastal sediments when acted on by natural bioturbation processes (Carteau Bay, Gulf of Fos, Mediterranean Sea) was studied under laboratory conditions.

Coupled anoxic nitrification/manganese reduction in marine sediments [PDF]

, 1999
Pore water and solid phase distributions of oxygen, manganese, and nitrogen from hemipelagic and shelf sediments sometimes indicate a close coupling between the manganese and nitrogen redox cycles.

Analysis of orientation errors in triaxial fluxgate sensors and research on their calibration methods [PDF]

Geoscientific Instrumentation, Methods and Data Systems
Three-axis magnetic flux gate sensors are widely used in Chinese geomagnetic observatories, but due to their directional errors it is necessary to study error correction methods to improve measurement accuracy.
