The biodiversity of the megabenthic assemblages mesophotic zone a Tyrrhenian seamount (Vercelli Seamount) is described using Remotely Operated Vehicle (ROV) video imaging from 100 m depth to top mount around 61 depth. This pinnacle hosts rich coralligenous community characterized by three different assemblages: (i) shows dense covering kelp Laminaria rodriguezii; (ii) southern side biocoenosis mainly dominated octocorals Paramuricea clavata and Eunicella cavolinii; while (iii) northern...
During the austral summer of 2014, an oceanographic cruise was conducted in Ross Sea framework RoME (Ross Mesoscale Experiment) Project. Forty-three hydrological stations were sampled within three different areas: northern (RoME 1), Terra Nova Bay 2), and southern 3). The ecological photophysiological characteristics phytoplankton investigated (i.e., size structure, functional groups, PSII maximum quantum efficiency, photoprotective pigments), as related to hydrographic chemical features....
Abstract Recent studies highlight an increase in the frequency and intensity of marine mass mortalities several species over past 30–40 years, mainly tropical temperate areas. In Mediterranean Sea these episodes particularly affect benthic suspension feeders, such as sponges cnidarians. The main objective this work was to document loss one seascapes, Paramuricea clavata forests at Marine Protected Area Tavolara Punta Coda Cavallo, Sardinia (Italy), during summer 2008. Data regarding colony...
Abstract This study analysed the anthropogenic microparticles in stomach content of European anchovy ( Engraulis encrasicolus ) Ligurian Sea (NW Mediterranean). The results showed that 30–40% anchovies had ingested (on average, 0.34 ± 0.29 fibres ind −1 and 0.12 fragments ). were probably via filtration, significantly correlated with gut fullness. Fibres mostly dark, but presence other colours was frequent, indicating a general lack selectivity. Plastic composed polyethylene polypropylene...
Plastic floating on the ocean surface represents about 1 % of all plastic in ocean, despite buoyancy most plastics. Biofouling can help to sink debris, which could explain this discrepancy. A set laboratory experiments was conducted investigate biofilm-induced effects different debris. Ten materials densities (buoyant/non-buoyant), sizes (micro/meso/macro), and shapes (irregular/spherical/cylindrical/flat), including facemasks cotton swabs, were evaluated. Biofilm incubated these from a few...
As part of the Ross Sea Marginal Ice Zone Ecology Project (ROSSMIZE) summer organic matter flux through water column was measured at 40 m depth in Terra Nova Bay. Water samples and material from a sediment trap on sea-bottom were analysed for their biochemical composition. A close coupling between composition collected found, resulting complex interactions physical biological processes. The processes are related to break-up melting ice cover occur mainly early season, whilst play key role...
An annual survey was carried out in Rapallo Harbour (Ligurian Sea, NW Mediterranean) to study the main stressors affecting macrobenthic communities.The harbour characterised by a relevant organic enrichment (between 51.9 mg g -1 and 109.6 ), which did not affect water column oxygenation, low but detectable heavy-metal contamination (on average Cu=135.0μg V=23.8 μg ).The seasonal changes heavy metal concentrations suggested significant increase tourist activities (i.e.boat movements) during...
In Antarctic and peri-Antarctic regions, benthic communities are persistent in time show high biomass large numbers of individuals, mainly consisting suspension deposit feeders.In fact, apart from recruitment, the major factor structuring these is flow organic matter pelagic domain to bottom, representing an important energy source for organisms.The aim this paper review, compile compare data earlier investigations Terra Nova Bay (Ross Sea) Straits Magellan, order come a more general...
Interactions between meio- and macrofaunal assemblages food availability were investigated in relation to tourism pressures on three beaches of the northern Adriatic Sea. All characterised by presence artificial reefs, freshwater inputs pressures. Beach sediments displayed high organic loads low protein chlorophyll a contributions bulk matter. Consequently, matter was mostly refractory composition and, thus, scarce nutritional quality. Macrofaunal community structure biomass related quantity...
Concentration levels, potential sources and bioavailability of trace elements in marine sediments from Kongsfjorden (Svalbard Islands, Norwegian Arctic) were assessed discussed. Surface collected by a Ponar grab characterised terms mineralogical composition, grain-size distribution, total organic carbon nitrogen percentage contents, major concentrations. Anthropogenic natural inferred lead isotope ratios, while the metal was evaluated size-fractionation solid-phase speciation studies...
The Antarctic Circumpolar Current (ACC) is the major current in Southern Ocean, isolating warm stratified subtropical waters from more homogeneous cold polar waters. ACC flows west to east around Antarctica and generates an overturning circulation by fostering deep-cold water upwelling formation of new masses, thus affecting Earth's heat balance global distribution carbon. characterized several mass boundaries or fronts, known as Subtropical Front (STF), Subantarctic (SAF), Polar (PF), South...
