Early evaluation of coastal nutrient over-enrichment: New procedures and indicators

摘要: Recent studies have provided compelling evidence for an accelerated anthropogenic impact on coastal systems, resulting in intense inputs of materials and nutrients from the continent. This has led scientists policymakers to encourage implementation monitoring programmes, which resulted multiplicity datasets. However surprisingly, only a few attempts been made couple observations with statistical mathematical tools detect, as soon data become available perturbations systems. Here, we propose new procedures evaluate state system, based building relative reference indicators nutrient over-enrichment. The techniques were tested some French systems using programme SOMLIT. Applied this dataset, multivariate rapidly identified evaluated anomalies continent three sites (Wimereux, Roscoff Villefranche-sur-Mer) 1997 onwards.
