Evaluating the influence of lake morphology, trophic status and diagenesis on geochemical profiles in lake sediments [PDF]

, 2010
Recent geochemical studies provide evidence that changes in vertical distributions of nutrients in lake sediments are driven by anthropogenic activities, based primarily on trends of increasing concentrations in upper sediment layers.

Modeling and interpreting element ratios in water and sediments: A sensitivity analysis of post-Chernobyl Ru : Cs ratios. [PDF]

, 1995
When elements are simultaneously added to lakes, experimentally or by accident, their ratios in the water phase and in bottom sediments can change with time due to differential partitioning between solution and suspended particles or sediments.

Diversity and abundance of diatoms (Bacillariophyceae) in sediments of the south coast of Iran [PDF]

بوم‌شناسی آبزیان, 2018
In this stud, the diversity and abundance of benthic diatoms were evaluated in 9 stations located in Persian Gulf (Sirik) and Oman Sea (Gwatar, Abshirinkon) in winter and spring of 1394 -1395.

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.

UNDERWATER CANYONS OF THE SOUTHWESTERN OUTSKIRTS OF SOUTHERN BAIKAL AS PRESUMABLE TRANSITERS OF TECHNOGENIC MATERIALS TO THE ABYSSAL SURFACE

Геодинамика и тектонофизика, 2023
Numerous publications by domestic and foreign authors deal with a significant role of underwater canyons in transit of loose material from the littoral to the abyssal surfaces of the seas. Lake Baikal fully corresponds in its hydrodynamic and bathymetric

Apparent OSL ages of modern deposits from Fåbergstølsdalen, Norway : implications for sampling glacial sediments [PDF]

, 2013
This work was funded by NERC, grant number F008589/1The application of optically stimulated luminescence (OSL) dating within glacial settings can be limited where sediments have not had their OSL signal fully reset by sunlight exposure.
