In Terra Nova Bay, a coastal area of the Ross Sea (Antarctica), the dissolved organic matter (DOM) (proteinlike and humiclike) in the seawater from two sampling stations was studied using the synchronous fluorescence technique and the evaluation of the dissolved proteins during the ice-free time lag (approximately four weeks). Moreover, a...

The variations in the expression of two hydrolytic ectoenzymes (leucine aminopeptidase – LA – and β glucosidase — BG) were studied in the southern Tyrrhenian Sea during spring 2004. This area is characterised by a complex morphology and hydrodynamism, which generate significant differences between different sectors, particularly in the 0–100 m...

The activities of two hydrolytic enzymes (leucine aminopeptidase and b glucosidase), belonging to the particle-bound enzymatic fraction, were measured in open-sea surface waters. Samples were collected along a transect crossing the Indian Ocean during the early NW monsoon period (November and December 2001). The latitudinal pattern of the...
