Coastal upwelling seen in ocean temperature data [PDF]

open access: yes, 2012
The phenomenon of wind-driven upwelling occurs when high coastal winds blow over the ocean surface, pushing warm surface waters offshore and allowing cooler, more nutrient rich water from below to rise up to the surface.

Future changes in coastal upwelling and biological production in eastern boundary upwelling systems

open access: yesNature Communications
Upwelling along oceanic eastern boundaries has attracted significant attention due to its profound effects on ocean productivity and associated biological and socioeconomic implications.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Decadal variability and trends of the Benguela upwelling system as simulated in a high-resolution ocean simulation [PDF]

open access: yesOcean Science, 2015
Detecting the atmospheric drivers of the Benguela upwelling systems is essential to understand its present variability and its past and future changes.

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.

Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

open access: yesNear Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Observations of vortex dipoles on the Benguela upwelling front [PDF]

open access: yes, 1987
Vortex dipoles are unusual phenomena in the mesoscale turbulence of the world ocean which have, for the greater part, gone unnoticed until the advent of satellite remote sensing.

Sublittoral soft bottom communities and diversity of Mejillones Bay in northern Chile (Humboldt Current upwelling system) [PDF]

open access: yes, 2006
The macrozoobenthos of Mejillones Bay (23°S; Humboldt Current) was quantitatively investigated over a 7-year period from austral summer 1995/1996 to winter 2002.

Intensity dependence of El Niño and La Niña evolution and mixed‐layer heat‐budget processes

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
El Niño–Southern Oscillation (ENSO) intensity modulates the spatial, temporal, and dynamical evolution of events strongly. El Niño SST anomalies shift westward with decreasing intensity, while La Niña anomalies remain spatially fixed. Stronger events initiate earlier and persist longer than weak events.

Diagnosing the 11‐year solar cycle's influence on the East Atlantic pattern

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A previously unidentified solar‐cycle response in the East Atlantic pattern is found in late winter at lag +3 years with larger amplitude than the NAO response. A statistically significant NAO response to the solar cycle is seen in late winter at lag 0 years.
