Efficient anaerobic sediment processing via a novel sediment core extruder [PDF]

MethodsX, 2022
Collection, extrusion and sampling of sediment cores are common methods used to explore the biogeochemistry of marine and lake deposits. We present a novel design for a sediment-core extruder that has greatly improved our core processing efficiency and ...

Sediment core analysis using artificial intelligence [PDF]

Scientific Reports, 2023
Subsurface stratigraphic modeling is crucial for a variety of environmental, societal, and economic challenges. However, the need for specific sedimentological skills in sediment core analysis may constitute a limitation.

Coring of Antarctic Subglacial Sediments [PDF]

Journal of Marine Science and Engineering, 2019
Coring sediments in subglacial aquatic environments offers unique opportunities for research on paleo-environments and paleo-climates because it can provide data from periods even earlier than ice cores, as well as the overlying ice histories ...

Compatibility of Diatom Valve Records With Sedimentary Ancient DNA Amplicon Data: A Case Study in a Brackish, Alkaline Tibetan Lake

Frontiers in Earth Science, 2022
Lake sediments represent valuable and widely used archives for tracking environmental and biotic changes over time. Past aquatic communities are traditionally studied via morphological identification of the remains of organisms.

Depth Profiles of Microplastic in Sediment Cores in the Mangrove Area of Kuala Gula Mangrove, Malaysia

Journal of Marine Science and Engineering, 2023
Microplastics are widespread in coastal and marine environments, and sediments serve as a sink for microplastics. In this study, four sediment cores were collected from the Kuala Gula Mangrove area.

Temporal trends of organophosphate esters in a sediment core from the tidal flat of Liao River estuary, Northeast China

Frontiers in Marine Science, 2023
The historical trends and inventory of organophosphate esters (OPEs) were investigated based on depth profiles of OPEs in sediment core collected from the tidal flat of the Liao River estuary in northeastern China.
