Testing the intermittent upwelling hypothesis: upwelling, downwelling, and subsidies to the intertidal zone [PDF]

open access: yesEcological Monographs, 2017
AbstractThe Intermittent Upwelling Hypothesis (IUH) posits that subsidies of larvae and phytoplankton to intertidal communities should vary unimodally along a gradient of upwelling from persistent upwelling to persistent downwelling with most subsidies occurring where upwelling is of intermediate strength and intermittent.

Summer temperatures, autumn winds, and thermal structure under the ice in arctic lakes of varying morphometry

open access: yesLimnology and Oceanography, Volume 70, Issue 7, Page 1817-1834, July 2025.
Abstract Ice‐covered lakes differ strongly from their ice‐free counterparts in their temperatures, heat budgets, and hydrodynamics. Nevertheless, due to a lack of detailed measurements, processes under the ice and their drivers are still understudied.

Mytilus californianus transplanted as upwelling bioindicators to two areas off Baja California, Mexico

open access: yesCiencias Marinas, 2003
 To study the spatial and temporal variability of bioavailable Cd, mussels (Mytilus californianus) were transplanted from a control zone to two upwelling areas off the northwestern coast of Baja California, Mexico.

Pre‐existing phytoplankton biomass concentrations shape coastal plankton response to fire‐generated ash leachate

open access: yesLimnology and Oceanography, Volume 70, Issue 7, Page 1883-1900, July 2025.
Abstract Climate‐driven warming is projected to intensify wildfires, increasing their frequency and severity globally. Wildfires are an increasingly significant source of atmospheric deposition, delivering nutrients, organic matter, and trace metals to coastal and open ocean waters.

Physical and Biogeochemical Phenology of Coastal Upwelling in the California Current System

open access: yesGeophysical Research Letters
In the California Current System (CCS), changes in the phenology (i.e., seasonal timing) of coastal upwelling alter the functioning of this productive marine ecosystem.

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

Predictive links between microbial communities and biological oxygen utilization in the Arctic Ocean

open access: yesLimnology and Oceanography, EarlyView.
Abstract Microbial metabolism influences rates of net community production (NCP), exerting a direct biological control on marine oxygen and carbon fluxes. In the Arctic, it is increasingly important to understand and quantify this process, as ecological and oceanographic conditions shift due to changing climate.

Toward predicting Dinophysis blooms off NW Iberia: a decade of events [PDF]

open access: yes, 2016
Dinophysis acuminata and Dinophysis acuta are recurrent species off NW Iberia but their outbreaks occur under different conditions. A decade (2004-2013) of weekly data for each species at two sentinel stations located at the entrance of Rias de Aveiro-AV

How marine heatwaves are reshaping phytoplankton in the Northeast Pacific

open access: yesLimnology and Oceanography, EarlyView.
Abstract In 2015 and 2019, the Northeast Pacific has undergone significant heatwave events that strongly disrupted marine ecosystems functioning and services. Here we use the data collected by the Continuous Plankton Recorder (CPR) survey to investigate the changes in summer phytoplankton abundance and morphology and show an increase in prolate (i.e ...

Biological and physical oceanographic observations pertaining to the trawl fishery in a region of persistent coastal upwelling [PDF]

open access: yes
An upwelling episode in the Point Sal region of the central California coast is examined by using data obtained by a data buoy. The episodes was interrupted by the abrupt abatement of the strong wind which promotes coastal upwelling.
