Abstract The Atacama Desert has been pointed out as one of the places on earth where highest surface irradiance may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low columns ozone water vapor. Aimed at characterization solar spectrum in Desert, we carried February-March 2015 ground-based measurements spectral (from ultraviolet to near infrared) seven locations that ranged from city Antofagasta (on southern pacific coastline) Chajnantor...
Enhancement of primary and export production following dust deposition pulses is well established for High Nutrient Low Chlorophyll regions, but the effect atmospheric on biogeochemistry oligotrophic gyre regions remains unclear. Here we report concentrations measured Gran Canaria, Canary Islands, concomitantly with upper water at time series station ESTOC (European Station Time in Ocean, Islands) during a 2‐year period from winter 1997 to 1999. located eastern subtropical Atlantic about 100...
On October 10 2011 an underwater eruption gave rise to a novel shallow submarine volcano south of the island El Hierro, Canary Islands, Spain. During large quantities mantle-derived gases, solutes and heat were released into surrounding waters. In order monitor impact on marine ecosystem, periodic multidisciplinary cruises carried out. Here, we present initial report extreme physical-chemical perturbations caused by this event, comprising thermal changes, water acidification, deoxygenation...
There are very few sets of long‐term measurements aerosol concentrations over the North Atlantic Ocean, yet such data is invaluable in quantifying atmospheric dust inputs to this ocean region. We present an 8‐year record total suspended particles (TSP) collected at three stations on Gran Canaria Island, Spain (Taliarte sea level, Tafira 269 m above level (a.s.l.) and Pico de la Gorra 1930 a.s.l.). Using wet dry deposition measurements, mean flux was calculated 42.3 mg −2 d −1 . Air mass back...
The gastrointestinal contents of twelve individuals from six odontocete species that stranded between 2018 and 2019 in the Macaronesian Region (Eastern North Atlantic) were examined for presence marine debris. In addition, concentrations eleven organic persistent contaminants (nonylphenols, bisphenols, phthalates pesticides) analysed muscle samples by liquid chromatography. No particles larger than 5 mm found, except two plastic labels found on same dolphin. On contrary, all animals...

Manta nets are commonly used for microplastics sampling although a number of limitations have emerged. In this study we compare the manta net to an innovative microplastic sampler, referred as MuMi, registered utility model. The results highlight large variability that can exist in outcomes different studies due lack harmonization between methods and differing factors such mesh size, representativeness or reproducibility volumes. Control over filtered volume is issue be improved trawl...
ABSTRACT The water‐insoluble phases of phosphate fertilisers have traditionally been considered an agronomic concern because their phosphorus bioavailability. However, this chemical behaviour with respect to its solubility in soil could be advantage from the point view environmental sustainability, since these phosphates are more stable and less susceptible blockage by adsorption. Hence, plants a long‐term bioavailable form for nutrition, which may increase performance crop. phosphate‐based...
Abstract We use new observations of stable water isotopes from a research cruise in early 2017 to highlight ocean‐ice interactions occurring under Filchner‐Ronne Ice Shelf, the largest Antarctic ice shelf. In particular, we investigate properties Shelf Water with temperature lower than surface freezing point, Filchner Depression. identify two main flavors emerging beneath which originate High Salinity end members distinct characteristics. Furthermore, these interact areas shelves different...
Broad scale sampling methods for microplastic monitoring in the open ocean waters remain a challenge oceanography. A large number of samples is required to understand distribution, abundance and fate particles environment. Despite more than decade widespread study, there currently no established time series measurements research community yet establish standardised set that will allow data be collected quick, affordable interoperable way. We present technique involving connection...
A modification of the method for determination aluminium by adsorptive cathodic stripping voltammetry its 1,2-dihydroxyanthraquinone-3-sulfonic acid (DASA) complex is described. Rapid achieved using staircase modulation and high potential scan speeds (20 V s–1). Square wave was found inefficient above 2 s–1 because pulse distorted ohmic drop. The also distorted, but not disturbed faradaic currents are obtained. sensitive to turbulence solution during scan, as a short time required (several...
Las masas de aire sahariano, acompañadas habitualmente por polvo en suspensión, afectan con asiduidad a las Islas Canarias y sus manifestaciones más extremas suponen un riesgo climático primer orden. En este trabajo se expone cual es la frecuencia concreta, qué resultados muestran primeras mediciones material litogénico tendencias indican los análisis realizados mediante combinación Climatología Sinóptica estadístico para una serie 28 años.
Detecting and predicting changes in coastal open-ocean ecosystems is a significant undertaking requiring detailed often real-time monitoring of physical, geological chemical parameters. Following the guidelines general objectives established by GOOS (Global Ocean Observing System) through its module COOP (Coastal Observations Panel), this paper describes design, first development stages some derived results network named Red ACOMAR Canarias (Red de Alerta, Control y Observaci ón MARina...
