Upwelling processes driven by contributions from wind and current in the Southwest East Sea (Japan Sea)

open access: yesFrontiers in Marine Science, 2023
The occurrence of coastal upwelling is influenced by the intensity and duration of sea surface wind stress and geophysical components such as vertical stratification, bottom topography, and the entrainment of water masses.

The impact of coastal upwelling on coral reef ecosystem under anthropogenic influence: Coral reef community and its response to environmental factors

open access: yesFrontiers in Marine Science, 2022
Mass coral bleaching is a severe threat to coral reefs in the era of global warming, and upwelling areas may serve as thermal refugia for coral reefs by mitigating the effects of heating anomalies.

Influences of Extreme Upwelling on a Coastal Retention Zone

open access: yesFrontiers in Marine Science, 2021
Coastal retention zones occur in the lee of headlands and within bays of coastal upwelling environments. Because retention zones can concentrate and retain communities of coastal planktonic organisms that would otherwise be advected offshore by wind ...

Long-term shift and recent early onset of chlorophyll-a bloom and coastal upwelling along the southern coast of Java

open access: yesFrontiers in Climate, 2023
Long-term change in the timing of coastal upwelling due to climate variations alters the heat budget and biogeochemical balance in the regional ocean and is an important issue in local fisheries.

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 along the southwest coast of India – ENSO modulation [PDF]

open access: yesAnnales Geophysicae, 2008
An index of El Niño Southern Oscillation (ENSO) in the Pacific during pre monsoon season is shown to account for a significant part of the variability of coastal Sea Surface Temperature (SST) anomalies measured a few months later within the wind ...

Automated detection of coastal upwelling in the Western Indian Ocean: Towards an operational “Upwelling Watch” system

open access: yesFrontiers in Marine Science, 2022
Coastal upwelling is an oceanographic process that brings cold, nutrient-rich waters to the ocean surface from depth. These nutrient-rich waters help drive primary productivity which forms the foundation of ecological systems and the fisheries dependent ...
