Intrusiones de polvo desde la península de la Guajira y sus efectos en las concentraciones de clorofila del sistema de surgencia de la Guajira.
Las intrusiones de polvo sobre los océanos representan una fuente de hierro que estimula la actividad biológica del fitoplancton causando aumentos en la Clorofila-a. En este trabajo se determinaron las emisiones de polvo ...
Environmental Drivers of Free-Living vs. Particle-Attached Bacterial Community Composition in the Mauritania Upwelling System
(Frontiers Media S.A., 2018-11-23)
Saharan dust input and seasonal upwelling along North-West Africa provide a model system for studying microbial processes related to the export and recycling of nutrients. This study offers the first molecular characterization ...
Aerosol and precipitation chemistry measurements in a remote site in Central Amazonia: the role of biogenic contribution
(Copernicus Gesellschaft Mbh, 2012-01-01)
In this analysis a 3.5 years data set of aerosol and precipitation chemistry, obtained in a remote site in Central Amazonia (Balbina, (1A degrees 55' S, 59A degrees 29' W, 174 m a.s.l.), about 200 km north of Manaus) is ...

Interactive effects of vertical mixing, nutrients and ultraviolet radiation: In situ photosynthetic responses of phytoplankton from high mountain lakes of Southern Europe.
(Copernicus Publications, 2013-02-14)
Global change, together with human activities, has resulted in increasing amounts of organic material (includ-ing nutrients) that water bodies receive. This input further attenuates the penetration of solar radiation, ...
Size distributions and temporal variations of biological aerosol particles in the Amazon rainforest characterized by microscopy and real-time UV-APS fluorescence techniques during AMAZE-08
(COPERNICUS GESELLSCHAFT MBHGOTTINGEN, 2012)
As a part of the AMAZE-08 campaign during the wet season in the rainforest of central Amazonia, an ultraviolet aerodynamic particle sizer (UV-APS) was operated for continuous measurements of fluorescent biological aerosol ...
