Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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.

Coastal Upwellings In The Sea of Marmara

open access: yesInternational Journal of Environment and Geoinformatics, 2023
Based on in situ measurements between 2017 and 2022 in the Sea of Marmara, three "warm and saline" upwelling events were observed during autumn and winter scientific expeditions. These observations were crucial and worth mentioning since the surface salinity value increased and even reached the lower layer value, which is ~38 psu, during the ...

Effects of upwelling duration and phytoplankton growth regime on dissolved-oxygen levels in an idealized Iberian Peninsula upwelling system [PDF]

open access: yesNonlinear Processes in Geophysics, 2020
We apply a coupled modelling system composed of a state-of-the-art hydrodynamical model and a low-complexity biogeochemical model to an idealized Iberian Peninsula upwelling system to identify the main drivers of dissolved-oxygen variability and to study

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.

The influence of coastal upwelling on the biodiversity of sandy beaches in South Africa [PDF]

open access: yes, 2015
Sandy beaches are often highly allochthonous, depending on external subsidies of carbon and nutrients. Despite this, sandy beach macrofaunal assemblages have received little attention regarding their response to enhanced primary productivity generated ...
