Overturned Eocene – Lower Pliocene alluvial stratum on the southern coast of Lake Baikal and its neotectonic significance

open access: yesГеодинамика и тектонофизика, 2021
The study is focused on a section of sediments exposed on the right bank of Mishikha River, Russia. These sediments have a wide range of ages, from the Eocene to the Lower Pliocene.

Leaching Properties of Estuarine Harbor Sediment Before and After Electrodialytic Remediation [PDF]

open access: yes, 2007
Electrodialytic remediation (EDR) can be used to extract heavy metals from a variety of different media. In this work, contaminated harbor sediments from two locations in the United States and one in Norway were subjected to EDR, and were compared with ...

Multidecadal increase in plastic particles in coastal ocean sediments

open access: yesScience Advances, 2019
Microplastics in ocean sediments increased exponentially from 1945 to 2009, serving as a geological proxy for the Anthropocene. We analyzed coastal sediments of the Santa Barbara Basin, California, for historical changes in microplastic deposition using ...

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

open access: yesGeoscientific 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

open access: yesГеодинамика 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

How do drying and rewetting events affect nutrient fluxes and bacteria dynamics in subtropical estuarine sediments? [PDF]

open access: yes, 2018
Drying and rewetting occur frequently in coastal marsh sediments due to oscillations of rising and falling tides, and episodic droughts and floods. Similarly, drying events also occur within freshwater systems due to changing precipitation patterns ...

Land reclamation using reservoir sediments in Tigray, northern Ethiopia [PDF]

open access: yes, 2012
Accelerated soil erosion leads to sedimentation in reservoirs and a decline in their life span. As many reservoirs in northern Ethiopia are dry at the end of the dry season, we were able to evaluate the potential of using reservoir sediments for land ...
