Eighty years of food-web response to interannual variation in discharge recorded in river diatom frustules from an ocean sediment core. [PDF]

, 2017
Little is known about the importance of food-web processes as controls of river primary production due to the paucity of both long-term studies and of depositional environments which would allow retrospective fossil analysis.

Seabed corrugations beneath an Antarctic ice shelf revealed by autonomous underwater vehicle survey: Origin and implications for the history of Pine Island Glacier [PDF]

, 2013
Ice shelves are critical features in the debate about West Antarctic ice sheet change and sea level rise, both because they limit ice discharge and because they are sensitive to change in the surrounding ocean.

Tip-Bed Velocity and Scour Depth of Horizontal-Axis Tidal Turbine with Consideration of Tip Clearance

Energies, 2019
The scouring by a tidal turbine is investigated by using a joint theoretical and experimental approach in this work. The existence of a turbine obstructs a tidal flow to divert the flow passing through the narrow channel in between the blades and seabed.

An experimental study of the engineering properties and erosion resistance of guar gum-reinforced loess

Shuiwen dizhi gongcheng dizhi, 2022
To reduce the erosion of the loess slope under the condition of rainstorms, the loess cured by guar gum is used to protect the slope surface. The engineering properties and erosion resistance of the guar gum-reinforced loess are studied by conducting the

Three-dimensional numerical simulation of wave-induced scour around a pile on a sloping beach

, 2021
A fully-coupled (hydrodynamic and morphologic) numerical model based on the open-source CFD package OpenFOAM is presented and utilized to simulate breaking wave induced scour around a pile on a sloping beach.

Reducing Open‐Circuit Voltage Losses in Wide‐Bandgap FAPbBr3 Perovskite Solar Cells for Continuous Unassisted Light‐Driven Water Splitting

Advanced Functional Materials, EarlyView.
The combination of formamidinium thiocyanate and 1,3‐propane diammonium iodide for bulk and top‐surface passivation, and a ternary fullerene blend to improve energy band alignment, suppresses energy losses in wide‐bandgap FAPbBr3 perovskite solar cells.

Scour Characteristics and Bearing Capacity Response of MGB Hybrid Foundations in Offshore Wind Applications

Journal of Marine Science and Engineering
Scour at offshore wind turbine foundations compromises their structural stability. This study investigates scour characteristics and their impact on the ultimate bearing capacity of a novel Monopile-Gravity-Bucket (MGB) hybrid foundation.
