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

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.

On the structural changes in the Brewer-Dobson circulation after 2000 [PDF]

, 2010
In this paper we present evidence that the observed increase in tropical upwelling after the year 2000 may be attributed to a change in the Brewer-Dobson circulation pattern.

Controlling the Collective Transport of Large Passive Particles With Suspensions of Microorganisms

Small, EarlyView.
Directional light stimuli induce the accumulation of microalgae in suspensions of Chlamydomonas reinhardtii. This accumulation triggers large scale bioconvection rolls capable of macroscale transport. Exploiting these bioconvective flows enables to collectively transport of hundreds of large passive particles, paving the way for future applications in ...

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

Geophysical 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.

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

Ciencias 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.

Predicting plankton net community production in the Atlantic Ocean [PDF]

, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Soluble trace metals in aerosols over the tropical south-east Pacific offshore of Peru [PDF]

, 2015
Bulk aerosol samples collected during cruise M91 of FS Meteor off the coast of Peru in December 2012 were analysed for their soluble trace metal (Fe, Al, Mn, Ti, Zn, V, Ni, Cu, Co, Cd, Pb, Th) and major ion (including NO3- and NH4+) content.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Solution of a Model for the Oceanic Pycnocline Depth: Scaling of Overturning Strength and Meridional Pressure Difference

, 2004
We present an analysis of the model by Gnanadesikan [1999] for the pycnocline depth in the ocean. An analytic solution for the overturning strength as a function of the meridional pressure difference is derived and used to discuss their mutual scaling ...
