The intensified trend of coastal upwelling in the South China Sea during 1982-2020

open access: yesFrontiers in Marine Science, 2023
Using sea surface temperature (SST) data from satellite observations and reanalysis, we revealed the long-term trend of coastal upwelling in the South China Sea (SCS) during 1982–2020.

What drives the spatial variability of primary productivity and matter fluxes in the north-west African upwelling system? A modelling approach [PDF]

open access: yesBiogeosciences, 2016
A comparative box analysis based on a multi-decadal physical–biogeochemical hindcast simulation (1980–2009) was conducted to characterize the drivers of the spatial distribution of phytoplankton biomass and production in the north-west (NW) African ...

Upwelling characteristics in the Gulf of Finland (Baltic Sea) as revealed by Ferrybox measurements in 2007–2013 [PDF]

open access: yesOcean Science, 2016
Ferrybox measurements have been carried out between Tallinn and Helsinki in the Gulf of Finland (Baltic Sea) on a regular basis since 1997. The system measures autonomously water temperature, salinity, chlorophyll a fluorescence and turbidity and takes ...

Wind variability across the North Humboldt Upwelling System

open access: yesFrontiers in Marine Science, 2023
Surface wind is taken as the primary driver of upwelling in the eastern boundary upwelling systems. The fluctuation of momentum flux associated with the variation in wind regulates the nutrient supply to the euphotic surface layer via changing the ...

Coastal Upwelling on a β-Plane [PDF]

open access: yesJournal of Physical Oceanography, 1973
Abstract The β effect is found to produce a poleward undercurrent in a wind-driven model of an eastern ocean circulation. The model is on an x, z plane and longshore derivatives of the velocity field are neglected. The nonlinear two-layer model is time-dependent and is solved numerically.

Coastal Upwelling Limitation by Onshore Geostrophic Flow in the Gulf of Guinea Around the Niger River Plume

open access: yesFrontiers in Marine Science, 2021
Wind-driven coastal upwelling can be compensated by onshore geostrophic flow, and river plumes are associated with such flow. We investigate possible limitation of the northeast Gulf of Guinea upwelling by the Niger River plume, using regional ocean ...

The common origin and degenerative evolution of flagella in Actinobacteria

open access: yesmBio, 2023
Species of the phylum Actinobacteria have long time been thought mostly non-motile and non-flagellated, in spite of their extraordinary diversity in morphology, physiology, and ecology.
