Marine mammals are under growing pressure as anthropogenic use of the ocean increases. Ship-strikes of large whales and loud underwater sound sources including airguns for marine geophysical prospecting and naval mid-frequency sonar are criticized for their possible negative effects on marine mammals. Competent authorities regularly require the imp...
Conference Paper
Whale sharks (Rhincodon typus) are usually observed in coastal areas throughout the highly productive tropical and subtropical regions. Whale sharks are filter feeders, feeding mainly on plankton, therefore their occurrence in these regions is tightly connected to seasonal increases in productivity. The Indo-Pacific sub-population in the last 75 ye...

A new process to remove carbon dioxide (CO2) from the atmosphere, by combining commercial industrial technologies with ocean liming and CO2 storage, is presented. The process aims to overcome the limiting factors of other negative emission technologies (cost and energy requirements, potential competition for land and freshwater) while simultaneousl...
Conference Paper
The potential effects of the ocean renewable energy sector on marine organisms have been comprehensively discussed and include effects on nearshore intertidal and benthic habitats, fish, fish habitats, large marine vertebrates (sea birds, marine mammals and large fish), oceanographic and coastal processes. However, due to the novelty of wave and ti...
Article
Full-text available
The opportunity to co-locate wind and wave energy exploitation is analysed in the Italian seas grounding on the rationale that benefits are greater when un-correlated resources are combined. The study shows that, although waves and winds are generally strongly correlated, in some conditions their correlation is lower and the combined energy harvest...

Full-text available
The Pelagos Sanctuary (NW Mediterranean) is known as a crucial summer feeding ground for fin whales (Balaenoptera physalus). Although several studies investigated the species’ habitat uses, most of them refer to short-time periods and rely only on presence data, without taking behaviour into account to discriminate foraging animals. Aiming to inves...

This paper provides a summary of 25 years of research on Risso's dolphins (Grampus griseus) in the western Ligurian Sea. Seasonal variations in abundance, distribution and habitat use were observed. Photographic mark-recapture methods provided a population size estimate for the period from 1998 to 2012, of about 100 individuals (95% CI of 60?220 in...
Chapter
Cuvier's beaked whale (Ziphius cavirostris G. Cuvier, 1823) is the only beaked whale species commonly found in the Mediterranean Sea. Until recently, species presence in this area was only inferred from stranding events. Dedicated cetacean surveys have increased our knowledge of the distribution of Cuvier's beaked whales, even though many areas sti...
