Abstract

We compare the dry deposition rates of atmospheric nitrogen to the sea in two models: a simple Gaussian puff model and a sophisticated mesoscale prognostic model, under a variety of meteorological conditions. The comparison is intended as a validation of the simple diagnostic schemes for transport and diffusion contained in the puff model. Agreement is generally shown to be good, except under low wind conditions. 1.- Introduction An environmental issue of growing concern is the impact of atmospheric loading of metals and nutrients on marine ecosystems. Over the past years such studies have been performed for the Mediterranean sea (Martin et al.,1991), the North Sea (Rendel et al,1992; Chester et al, 1993), the Kattegat
