Low confidence in multi-decadal trends of wind-driven upwelling across the Benguela Upwelling System [PDF]

open access: yesEarth System Dynamics, 2023
Like other eastern boundary upwelling systems, in the Benguela Upwelling System, the upwelling along the coastline is primarily alongshore-wind-driven. In contrast, it is mainly driven by the wind stress curl farther offshore.

Reviews and syntheses: Physical and biogeochemical processes associated with upwelling in the Indian Ocean [PDF]

open access: yesBiogeosciences, 2021
The Indian Ocean presents two distinct climate regimes. The north Indian Ocean is dominated by the monsoons, whereas the seasonal reversal is less pronounced in the south.

A novel approach to quantify metrics of upwelling intensity, frequency, and duration.

open access: yesPLoS ONE, 2021
The importance of coastal upwelling systems is widely recognized. However, several aspects of the current and future behaviors of these systems remain uncertain.

Nitrogen supply in the upwelling of mid-west region of the South China Sea: The case of mesopelagic fishes

open access: yesEcological Indicators, 2023
Coastal upwelling zone hosts most fishing grounds worldwide and nitrogen dynamics in those systems mainly have been addressed through the nutrients replenished the ecosystem.

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.

Using TPI to Map Spatial and Temporal Variations of Significant Coastal Upwelling in the Northern South China Sea

open access: yesRemote Sensing, 2021
Based on Himawari-8 Sea Surface Temperature (SST) data and the semi-automatic Topographic Position Index (TPI)-based mapping method, this study maps the significant coastal upwelling in the northern South China Sea (NSCS).

Mapping the Coastal Upwelling East of Taiwan Using Geostationary Satellite Data

open access: yesRemote Sensing, 2021
Coastal upwelling is important for coastal ecosystems and the blue economy because of its large productivity and large potential for catching fish. However, coastal upwelling along the Taiwan east coast has received little attention from the research ...

A New Upwelling Index for the Moroccan Atlantic Coast for the Period between 1982–2021

open access: yesRemote Sensing, 2023
Being a component of the Eastern Boundary Upwelling (EBU) ecosystem, Morocco’s Atlantic coast presents high biological production throughout the year, with seasonal variations in upwelling dynamics.

Representative Diatom and Coccolithophore Species Exhibit Divergent Responses throughout Simulated Upwelling Cycles

open access: yesmSystems, 2021
Wind-driven upwelling followed by relaxation results in cycles of cold nutrient-rich water fueling intense phytoplankton blooms followed by nutrient depletion, bloom decline, and sinking of cells.

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 ...
