African dust inputs have important effects on the climate and marine biogeochemistry of the subtropical North Atlantic Ocean. The impact of dust inputs on oceanic carbon uptake and climate is dependent on total dust deposition fluxes as well as the b

The variability of dust inputs in the Canary Islands Azores Gibraltar Observations (CANIGO) area is discussed for the period 1997–1998. The samples were collected daily at “Pico de la Gorra”, at the top of Gran Canaria Island (1980 m). A season

A three-year dataset of particle deposition flux measurements in Gran Canaria, Canary Islands, is presented. As part of this work, a comparison between wet and dry surrogate surfaces to estimate dry deposition fluxes was carried out over a period of

A fast adsorptive stripping voltammetric procedure for the determination of ultratrace amounts of iron in unpurged oceanic waters is reported. The method is based on that developed by van den Berg et al. [l]. It was modified to increase the sensitivi

The voltammetric determination of trace metals in seawater suffers from the interference of dissolved oxygen and engine vibrations onboard ship. It is here attempted to overcome these interferences using a high-frequency (1 to 20 kHz) staircase modul

The effects of the potential scan speed on the adsorptive cathodic stripping voltammetric determination of zinc-tetramethylenedithiocarbamate complexes in sea water were investigated. It was observed that an increase in scan speed increases the peak
