Quantifying mud settling velocity as a function of turbulence and salinity in a deltaic estuary Cont. Shelf Res. (IF 2.3) Pub Date : 2024-01-19 M. McDonell, K. Strom, J. Nittrouer, G. Mariotti
Mud settling velocity in coastal regions is controlled by flocculation, which in turn strongly depends on turbulence, chemistry, and biology of the water-sediment mixture. As a result, mud settling velocity can be poorly constrained, and vary in space and time by orders of magnitude. Here we quantified mud settling velocity in Barataria Basin, a deltaic estuary in Louisiana (USA), using three independent

Pockmarks are concave depressions on the sea bottom produced by fluid escape from subaqueous sediments which can be found worldwide in muddy and silt/clay sediments. Due to their morphological and geochemical characteristics, certain pockmarks play an important role in structuring benthic communities, and consequently, they have been proposed to be protected. The present research provides a characterisation

The effect of alongshore wind stress on a buoyancy current’s stability Cont. Shelf Res. (IF 2.3) Pub Date : 2023-12-03 K.H. Brink
Buoyancy fronts reach from the surface to the bottom over continental shelves, separating light inshore water from denser offshore water, and are known to be responsive to Ekman transport (and associated return flow at depth) driven by alongshore winds. The consequent changes in frontal structure are clearly related to changes in the gravitational Available Potential Energy (APE), so it is reasonable

Effects of tidal cycles on the variability of microbial communities in a semiclosed bay Cont. Shelf Res. (IF 2.3) Pub Date : 2023-11-19 Fahui Gong, Suixuan Huang, Wei Xie, Han Zhang, Fei Lan, Kedong Yin
Shallow sediment-water plays an important role in transforming organic matter in estuaries. As a shallow bay often flanks a large estuary, the estuarine water enters the shallow bay during flood tides and exits during ebb tides. The inundation between flood and ebb tides in the shallow bay serves as an incubation of the bay water and sediment. However, little is known about the effects of tidal cycles

River flooding is expected to increase in frequency and severity under climate change. However, the impact of extreme river flooding on the coastal carbon cycle has rarely been studied. A severe Changjiang flood occurred in the summer of 2020, which was the largest Changjiang flood in the last 20 years since 2000. This extreme flood resulted in the export of great amounts of nitrate (6.4 × 108 mol d−1)

(IF 2.3) Pub Date : 2023-09-14 C. Fontanier, B. Mamo, N. Dubosq, B. Lamarque, S. Rigaud, S. Schmidt, P. Lebleu, D. Poirier, M.-A. Cordier, A. Grémare, B. Deflandre
Living continental shelf foraminifera were studied at three stations along a shore to open ocean transect between 39 and 69 m depth in the West-Gironde Mud Patch (WGMP) (Bay of Biscay, NE Atlantic). The aim of this work was to understand how the complex temporal variability of the environmental conditions (e.g., hydrosedimentary processes, sedimentary organic matter, oxygenation levels) controls foraminiferal

Impacts of vertical mixing and ice-melt on N2O and CH4 concentrations in the Canadian Arctic Ocean Cont. Shelf Res. (IF 2.3) Pub Date : 2023-09-16 Kate H. Schuler, Philippe D. Tortell
The sources and sinks of methane (CH4) and nitrous oxide (N2O) in the Arctic Ocean are subject to significant uncertainty, due to a combination of high spatial and temporal variability, and limited observations over relevant scales. To address this, an underway ship-board system was developed to simultaneously and continuously measure surface water CH4 and N2O concentrations in the Canadian Arctic
