Wave energy assessment based on reanalysis data calibrated by buoy observations in the southern South China Sea

open access: yesEnergy Reports, 2022
This study assesses wave energy by combining long-term model reanalysis data with in situ observations in a multi-island region. A buoy was deployed in the center area of the southern South China Sea (SCS) for 16 consecutive months. Neural network models

Physical processes and biological productivity in the upwelling regions of the tropical Atlantic [PDF]

open access: yesOcean Science, 2023
In this paper, we review observational and modelling results on the upwelling in the tropical Atlantic between 10∘ N and 20∘ S. We focus on the physical processes that drive the seasonal variability of surface cooling and the upward nutrient flux ...

Variation and Change of Upwelling Dynamics Detected in the World’s Eastern Boundary Upwelling Systems

open access: yesFrontiers in Marine Science, 2021
Global increases in temperature are altering land-sea temperature gradients. Bakun (1990) hypothesized that changes within these gradients will directly affect atmospheric pressure cells associated with the development of winds and will consequently ...

Dynamics of wind-driven upwelling and relaxation between Monterey Bay and Point Arena: Local-, regional-, and gyre-scale controls [PDF]

open access: yes, 2009
In north and central California, equatorward winds drive equatorward flows and the upwelling of cold dense water over the shelf during the midspring and summer upwelling season.

Faunal response to benthic and hyporheic sedimentation varies with direction of vertical hydrological exchange [PDF]

open access: yes, 2014
1. Sedimentation and clogging of benthic and hyporheic zone substrates is increasingly being recognised as one of the greatest threats to the ecological integrity of riverine ecosystems globally. This ex-situ study examined the influence of sedimentation

Variability in upwelling across the tropical tropopause and correlations with tracers in the lower stratosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Temporal variability of the upwelling near the tropical tropopause on daily to annual timescales is investigated using three different estimates computed from the ERA-Interim reanalysis.

Marine radiocarbon reservoir effect of coastal waters off Cape Verde archipelago [PDF]

open access: yes, 2011
Quantification of the marine radiocarbon reservoir effect (Delta R) is essential in order to calibrate conventional C-14 dates from marine shell samples with reliability.

The "African humid period" and the record of marine upwelling from excess ^(230)Th in Ocean Drilling Program Hole 658C [PDF]

open access: yes, 2006
Using a high-resolution ^(230)Th normalized record of sediment flux, we document the deglacial and Holocene history of North African aridity and coastal upwelling at Ocean Drilling Program Hole 658C. At both the end of the Younger Dryas and after the 8.2

Variations of the Somali upwelling since 18.5 ka BP and its relationship with southwest monsoon rainfall [PDF]

open access: yesClimate of the Past, 2018
Somali upwelling history has been reconstructed for the last 18.5 ka BP based on biogenic silica fluxes estimated from a sediment core retrieved from the western Arabian Sea.

Physiological responses of Pocillopora corals to upwelling events in the Eastern Tropical Pacific

open access: yesFrontiers in Marine Science, 2023
Upwelling events can change the sea water conditions within few hours during several months on a seasonal regimen. These events are predicted to intensify due to climate change, exposing shallow benthic organisms to hypoxia and thermal stress, among ...
