Study of the effects of Ekman dynamics in the bottom boundary layer on the Black Sea continental slope

Russian Journal of Earth Sciences, 2020
A possible ventilation mechanism of the aerobic zone in the Black Sea may exist, caused by a descent of oxygen-containing water down the bottom slope in the Ekman boundary layer.

A Heuristic Framework for Next-Generation Models of Geostrophic Convective Turbulence [PDF]

, 2018
Many geophysical and astrophysical phenomena are driven by turbulent fluid dynamics, containing behaviors separated by tens of orders of magnitude in scale.

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Interplay of wind-driven processes and subsurface oscillations along the leeward coastline of a tropical reef island

Frontiers in Marine Science
The thermal structure of tropical reef systems is shaped by air-sea interactions, turbulent mixing, and subsurface-driven processes, yet their complex dynamics and interactions are not well understood.

Mesoscale and wind-driven intra-annual variability in the East Auckland Current

Scientific Reports, 2021
Intra-annual variability in the East Auckland Current (EAuC) was studied using a year-long timeseries of in situ and remotely-sensed velocity, temperature and salinity observations.

Prey DNA Detection in Lycosid Spiders Is Primarily Influenced by Time Since Feeding and Primer Choice

Entomologia Experimentalis et Applicata, EarlyView.
Gut content analysis using DNA metabarcoding has improved understanding of predator–prey interactions involving spiders. We tested how starvation before feeding, time since feeding, spider size, and the presence of egg sacs or spiderlings affect prey DNA detection in Lycosidae.

of the global combined atmosphere-ocean heat flux and so is important for the mean climate of the Atlantic sector of the Northern Hemisphere. This meridional heat flux is accomplished by both the Atlantic Meridional Overturning Circulation (AMOC) and

The Emotional Valence Paradox in Social media: A Computational Linguistic Analysis of How Sentiment, Emotion, and Content Domain Predict Social Comparisons on Rednote

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (

Determining the depth and upwelling speed of the equatorial Ekman layer from surface drifter trajectories [PDF]

Ocean Science
In this work, trajectories of more than 500 drogued surface drifters launched in the equatorial ocean since 1979 are analyzed by employing the results of a new Lagrangian theory of poleward transport from the Equator forced by the prevailing trade winds.

Biological activity in the wake of an island close to a coastal upwelling [PDF]

, 2008
Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.
