Organic matter consumption and decomposi- tion were studied in four experimental systems, having collected di erent organic substrates in the Ross Sea in December 1994. For the experimental approach selected, processes normally acting on a mixed pool of substances could be separated and the main features of each phe- nomenon could be focused...

Water samples were collected in the north-east Atlantic Ocean between the Azores and Madeira (33°N-36°N and 24°W-26°W) during the Oceanographic Cruise SEMAPHORE in June 1993. Temperature, salinity, nutrients (nitrate and phosphate) and particulate organic matter (organic carbon, organic nitrogen, carbohydrates, proteins and phytopigment) were...

The results of a study on ectoenzymatic activity (the enzyme activity bound to particles larger than 0.2 µm) and its relation to organic particle concentration are reported here. The sampling was carried out during the 1994 Antarctic spring, at a fixed station (Station 11) in the polynya of the Ross Sea, an area characterised by quick changes...

Emergy analysis was applied to three municipalities (Portofino, Santa Margherita Ligure and Rapallo) of the Liguria Region coast, where tourism and cruise tourism are thriving. The results were compared with traditional economic indices. The territorial assessment of the municipalities was analysed by comparing the environmental costs with the...

Changes imposed to nature by human activities and related impacts on all environmental matrices have become a critical issue. Gradually, humans began to perceive and face the magnitude of the impact of human economy on natural ecosystems and the implications for human well-being. From this perception, the concepts of natural capital and...

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...

Since the 17th century, the Tonnarella of Camogli, a small tuna trap, has been used to catch pelagic fish along the western coast of the Portofino Promontory (Ligurian Sea, Northwestern Mediterranean). The availability of long‐term datasets on fish yields (1950–1974 and 1996–2011), with information related to the seawater temperatures and the...
