'''Time scales for pollution assessment''' can be considered using three commonly used methods: [[Flushing Time|flushing time]], [[residence time]] and age.  In this article the methodologies and tools to quantify each of these methods is explained as well as the applicability of each method.

Transport time scales are useful tools to quantify the importance of hydrodynamic processes in the transport and fate of [[pollutant|pollutants]] in coastal and estuarine water systems. Indeed, the water quality of a system depends crucially on the retention of [[pollutant|pollutants]] within the system and its ability to flush them out. Transport time scales are often compared with the [[pollutant]] source time scales or biogeochemical processes to evaluate the relative importance of physical and water quality processes. <ref name="Monsen">Monsen N.E., Cloern J.E. and Lucas L.V (2002).

Biodiversity in the European Seas

Lophelia pertusa Author: S. Ross et al., UNCW (www.safmc.net)
This article summarises the biodiversity in the European Seas. It is based on reports (publish date: 31 may 2002) of the ‘European Environmental Agency’ (visited 31/08/2007)(EEA), in which the marine biodiversity of each European sea is described in some detail. In the ‘EEA reports’ an overview is given of the most important physical, biological and exploitation characteristics, the main threats to biodiversity and the policies at work (nature protection and protection of marine resources by restrictions on fishing and hunting).The contents of these reports are shown together with an indication of the most relevant information.
