Net primary productivity, upwelling and coastal currents in the Gulf of Ulloa, Baja California, Mexico
(Ocean Science, 2012)
The Gulf of Ulloa, a highly productive area off the western coast of the Baja California Peninsula, is examined for five successive years (2003–2007) by using satellite data and seasonal net primary productivity (NPP) ...
Revisiting chlorophyll data along the coast in north-central Chile, considering multiscale environmental variability
(Sociedad de Biologia de Chile, 2006)
Phytoplankton abundance in the surface mixed layer of the coastal ocean responds to environmental changes at various time scales. Here the "warm", "cold" and "neutral" phases of "three environmental cycles" have been jointly ...
Heterotrophic bacterial production in the eastern South Pacific: longitudinal trends and coupling with primary production
(2008)
Spatial variation of heterotrophic bacterial production and phytoplankton primary production were investigated across the eastern South Pacific Ocean (−141° W, −8° S to −72° W, −35° S) in November–December 2004. Bacterial ...
Fluctuación temporal de la estructura de la comunidad microbiana planctónica en la zona eufótica del Canal Beagle (Tierra del Fuego, Argentina)Temporal fluctuation in the structure of the microbial planktonic community in the euphotic zone of Beagle Channel (Tierra del Fuego, Argentina)
(2018-03-22)
Los organismos planctónicos unicelulares que conforman los primeros niveles de la trama trófica marina presentan, en distintas escalas, respuestas rápidas ante las fluctuaciones ambientales y las interacciones biológicas. ...
Produção primária com ênfase na excreção de matéria orgânica dissolvida por populações fitoplanctônicas naturais do reservatório de Barra Bonita, SP
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2006-09-04)
To quantify the primary productivity in a fixed sampling station at the Barra Bonita Reservoir, monthly sampling from July/03 to August/04 were performed in three different depths in the euphotic ...

(2018-01-01)
Aim: The aim of this study was to inventory the diatom species of order Surirellales present in the surface sediments of tropical reservoirs (São Paulo State, Brazil) and to correlate their distribution with environmental ...
Satellite evidence for pervasive water eutrophication in the Doce River reservoirs following the collapse of the Fundao dam in Brazil
(Elsevier B.V., 2021-03-01)
One of the worst socio-environmental disasters to mark the history of Brazil and the world occurred in November 2015 and involved the mining sector. The collapse of the Fundao dam released approximately 43 million m(3) of ...
Coastal upwelling activity on the Pacific shelf of the Baja California Peninsula
(Journal of Oceanography, 2003)
High primary productivity on the Pacific coast of the Baja California Peninsula is usually related to coastal upwelling activity that injects nutrients into the euphotic zone in response to prevailing longshore winds (from ...
Analyzing the status of submerged aquatic vegetation using novel optical parameters
(Taylor & Francis Ltd, 2016-08-20)
The reservoirs constructed throughout Brazil for electrical power generation following its industrial and socioeconomic development now favour abundant aquatic macrophyte growth. Nova Avanhandava Reservoir is fully inhabited ...
Foraminíferos bentónicos recientes en sedimentos de fondo de la cuenca de panamá (pacífico colombiano), como indicadores de productividad y oxigenación
(Instituto de Ivestigaciones Marinas y Costeras-INVEMAR, 2003-01-01)
Thirteen deep-sea samples (core-tops) from the Panama Basin, Colombian Pacific, were analysed for benthonic foraminifera in the >150µm size fraction. Based on the microfaunal content, three zones are recognised in the ...
