A moored profiling platform to study turbulent mixing in density currents in a large lake
David Andrew Barry, Ulrich Lemmin, François Mettra, Rafael Sebastian Reiss, Valentin Kindschi, Benjamin Daniel Graf
During calm cooling periods, differential cooling can induce winter cascading which is an important process for littoral-pelagic exchange and deep water renewal in large, deep lakes (Fer et al., 2001; Peeters et al., 2003). Generated in the shallow near-sh ...
2023Density currents driven by differential cooling in lakes: occurrence, dynamics and implications for littoral-pelagic exchange
Cross-shore flows exchange water laterally in lakes, with ecological implications for the ecosystem. One example is the convective circulation induced by differential cooling, also known as the thermal siphon. This lateral flow forms when the sloping sides ...
EPFL2022Biomass burning and marine aerosol processing over the southeast Atlantic Ocean: a TEM single-particle analysis
This study characterizes single-particle aerosol composition from filters collected during the ObseRvations of Aerosols above CLouds and their intEractionS (ORACLES) and CLoud-Aerosol-Radiation Interaction and Forcing: Year 2017 (CLARIFY-2017) campaigns. I ...
COPERNICUS GESELLSCHAFT MBH2022Low‐Volatility Vapors and New Particle Formation Over the Southern Ocean During the Antarctic Circumnavigation Expedition
Julia Schmale, Andrea Baccarini, Robin Lewis Modini
During summer, the Southern Ocean is largely unaffected by anthropogenic emissions, which makes this region an ideal place to investigate marine natural aerosol sources and processes. A better understanding of natural aerosol is key to constrain the preind ...
2021Meridional and vertical variations of the water vapour isotopic composition in the marine boundary layer over the Atlantic and Southern Ocean
Julia Schmale, Sebastian Johannes Heinz-Josef Landwehr
Stable water isotopologues (SWIs) are useful tracers of moist diabatic processes in the atmospheric water cycle. They provide a framework to analyse moist processes on a range of timescales from large-scale moisture transport to cloud formation, precipitat ...
COPERNICUS GESELLSCHAFT MBH2020Photic stress on coral reefs in the Maldives: The Amphistegina bleaching index
Arthur Adams, Aurélie Angéloz, Anaël Lehmann
The Amphistegina Bleaching Index (ABI) was applied to three Maldivian reefs in the Rasdhoo and North Ari Atolls in 2018, during normal sea surface temperature conditions. This dataset was then compared with a 2015, pre-coral bleaching study. The results pr ...
ELSEVIER2020Temperature statistics in the deep ocean
The study of turbulence in geophysical flows benefits from the growing amount of data available via modern sensor technologies. It is now possible to obtain detailed statistical characterisation of turbulence from field observations. By ``statistical,'' we ...
2017Efficiency of turbulent mixing in the abyssal ocean circulation
Turbulent mixing produced by breaking of internal waves plays an important role in setting the patterns of downwelling and upwelling of deep dense waters and thereby helps sustain the global deep ocean overturning circulation. A key parameter used to chara ...
2017Transient perturbation growth in time-dependent mixing layers
Cristobal Manuel Arratia Martinez
We investigate numerically the transient linear growth of three-dimensional (3D) perturbations in a homogeneous time-evolving mixing layer in order to identify which perturbations are optimal in terms of their kinetic energy gain over a finite, predetermin ...
Cambridge University Press2013Experimental study of the impact of large-scale wind farms on land-atmosphere exchanges
Fernando Porté Agel, Wei Zhang, Corey Dean Markfort
Large-scale wind farms, covering a significant portion of the land and ocean surface, may affect the transport of momentum, heat, mass and moisture between the atmosphere and the land locally and globally. To understand the wind-farm-atmosphere interaction ...
