The spatial and temporal variability of nearshore winds in eastern boundary current systems affect the oceanic heat balance that drives sea surface temperature changes. In this study, regional atmospheric simulations are used to document such processes during an coastal jet event off central Chile. is well reproduced by model associated with migration anomalous anticyclone southeastern Pacific region October 2000. A robust feature simulation a sharp wind dropoff, which insensitive...
Abstract. Two physical mechanisms can contribute to coastal upwelling in eastern boundary current systems: offshore Ekman transport due the predominant alongshore wind stress and pumping cyclonic curl, mainly caused by abrupt decrease (drop-off) a cross-shore band of 100 km. This drop-off is thought be an ubiquitous feature systems regulate relative contribution both mechanisms. It has been poorly studied along central-northern Chile region because lack measurements shoreline relatively low...
Off Northern Chile, baleen whales use the area around Isla Chañaral as a feeding ground where they forage on euphausiids. is part of highly productive Humboldt Archipelago (∼ 28°S-29°S) within Current System (HCS). In this study, we seek to understand sub-mesoscale spatial distribution fin and blue their prey using systematic opportunistic visual sighting data acoustic backscatter zooplankton from an Acoustic Zooplankton Fish Profiler (AZFP); examine oceanographic dynamics wider with...
Abstract In Eastern Boundary Upwelling Systems (EBUS), the upwelling favorable wind speeds decrease toward coast in so‐called drop‐off coastal strip, which has been shown to be influential on dynamics, particularly terms of relative contributions Ekman drift and suction upwelling. Currently, length scale is not properly resolved by atmospheric forcing regional ocean models EBUS, featuring a smoother cross‐shore profile that results stronger near‐shore could partly explain cold bias often...
Environment imposes physiological constraints which are life-stage specific as growth-maintenance and/or growth-reproduction energetic requirements size and volume-dependent. The scallop Argopecten purpuratus , one of the most important bivalve species subjected to fishery aquaculture along Humboldt Current System, inhabits spaces affected by continuous changes in temperature, pH, oxygen, food availability driven remote local oceanographic processes. Specifically, Chile, this is mainly...
En Chile los cultivos del ostión norte Argopecten purpuratus han sido desarrollados intensivamente a partir de la captación semillas en ambiente natural y desde principios 1980 con obtenidas hatchery.Para aportar información sobre el desempeño este estudio se comparó, mediante ANCOVA, crecimiento longitud entre cohortes producidas hatchery Tongoy, Chile.Se evaluó consistencia esta comparación distintos años estaciones, comparándose parejas simultáneamente 2003 (primavera), 2005 (invierno)...
Abstract. Proxy records have long documented the existence of multicentury hydroclimate anomalies in Altiplano South America. However, causes and mechanisms these events are still largely unknown. Here we present results an innovative climate modelling experiment that explores oceanic drivers atmospheric conducive to long-term precipitation variability southern part (18–25° S). For doing so, performed 100-yr-long simulations using a regional model forced by climatological conditions resulted...
The relationship between phytoplankton abundances and wind forcing in upwelling systems involves a number of processes that make the nonlinear nature. In particular, although upwelling-favorable winds tend to provide nutrients for growth, they can also induce export both biomass open ocean through Ekman eddy-induced transport, or dilution populations vertical mixing, which negatively impacts increase biomass. These are essentially interact antagonistically synergistically on overall coastal...
The Humboldt Archipelago (HAp), located off north-central Chile (~28° - 33° S) is one of the most productive marine zones Current System (HCS). This area lies within a permanent upwelling zone, characterized by two centers, 100 km apart, that define Coquimbo Bays (CBS). resulting increase in primary productivity and larval retention are mentioned as main factors explain high biodiversity. However, how these centers interact remains unclear due to interplay various physical features such...
Planning agricultural procedures needs to take into account meteorological conditions. However, because of high associated costs, the density stations is often not enough cover all cultivated or potentially areas. In this article we present a methodology estimate seasonal maximum and minimum mean temperature in area using data registered sole few stations. The procedure based on mesoscale modeling, which allows variables be spatially distributed considering synoptic local characteristics....
