Chemical analyses of suspended particulate matter collected in the northeast Atlantic
Abstract--Analyses of uspended particulate matter have been carried out on samples from different depths between 0 and 4000 m, in the northeast Atlantic. The total mass of suspended matter, parti-culate organic arbon, silicon, iron, alttminium, phosphorus, were determined. In surface waters (0-150 m...

Summary: | Abstract--Analyses of uspended particulate matter have been carried out on samples from different depths between 0 and 4000 m, in the northeast Atlantic. The total mass of suspended matter, parti-culate organic arbon, silicon, iron, alttminium, phosphorus, were determined. In surface waters (0-150 m), the average concentration in particulate matter (mass per vol.) is 3.8 higher than between 150 and 4000 m. For carbon the ratio is 4.5 and for phosphorus 10.8. On the other hand, silicon, aluminium and iron are often as abundant in deep water as in the surface layer. R~um~-Des analyses leparticules en suspension ont 6t6 faites ~t partir d'6chantillons pr~lev~s diverses profondeurs entre 0 et 4000 m, darts l'Atlantique nord-est. Le poids de particules, les teneurs en carbone organique, silicium, fer, aluminium, phosphore ont 6t6 d6termin~s. Darts la zone super-ficielle (0-150 m), la concentration moyenne des particules (en masse par vol.) est 3,8 fois plus importante q'entre 150 et 4000 m. Pour le carbone, le rapport est 4,5 et pour le phosphore il est de 10,8. Par contre le silicium, l'aluminium etle fer sont souvent aussi abondants darts la zone profonde que dans la zone superficielle. |
