In remote marine areas, biogenic productivity and atmospheric particulate are coupled through dimethylsulfide (DMS) emission by phytoplankton. Once in the atmosphere, gaseous DMS is oxidized to produce H2SO4 methanesulfonic acid (MSA); both species can affect formation of cloud condensation nuclei. This study analyses eight years aerosol evolution variability at two Arctic sites: Thule (76.5° N, 68.8° W) Ny Ålesund (78.9° 11.9° E). Sea ice plays a key role determining MSA concentration polar...
Within BioAPRoS project (Biogenic Aerosol and Primary production in the Ross Sea) two research campaigns were conducted coastal area of Terra Nova Bay (TNB) front Italian Base Mario Zucchelli Station, Sea, Antarctica, spanning from 13/11/2018 to 30/01/2019 (BioAPRoS18), 01/12/2019 30/01/2020 (BioAPRoS19), an classified as Marginal Ice Zone (MIZ) during this period. The goal was study nutrient dynamics, phytoplankton biomass taxonomic composition upper mixed layer (UML), exploring...
According to recommendations of the international community phytoplankton functional type algorithm developers, a set experiments on marine algal cultures was conducted (1) investigate uncertainties and limits in group discrimination from hyperspectral light absorption properties assemblages with mixed taxonomic composition, (2) evaluate extent which modifications spectral features due variable conditions affect optical phytoplankton. Results showed that signatures multiple species can be...
The estimation of chlorophyll concentration in marine waters is fundamental for a number scientific and practical purposes. Standard ocean color algorithms applicable to moderate resolution imaging spectroradiometer (MODIS) imagery, such as OC3M MedOC3, are known overestimate ([CHL]) Mediterranean oligotrophic waters. performances these currently evaluated together with two relatively new algorithms, OC5 SAM_LT, which make use more the spectral information MODIS data. This evaluation...
Abstract. This paper presents the results of simultaneous high time-resolution measurements biogenic aerosol (methane sulfonic acid (MSA), non-sea salt sulfate nssSO42-) with its gaseous precursor dimethylsulfide (DMS), performed at Italian coastal base Mario Zucchelli Station (MZS) in Terra Nova Bay during two summer campaigns (2018–2019 and 2019–2020). Data on atmospheric DMS concentration are scarce, especially Antarctica. The maximum MZS occurs December, one month earlier than other...
Abstract 1. Pelagic mucilage aggregates are composed of phytoplankton and bacteria, whilst macro‐ micro‐phytobenthos bacteria make up the benthic ones. During summer 1991 massive aggregates, both pelagic benthic, appeared in Tyrrhenian Sea, seriously damaging fisheries, tourism biocoenoses. Only a few, loose mucilages have persisted during last decade although ones shown great resurgence autumn. 2. 14 C autoradiographies show that is photosynthesized excreted by micro‐ macroalgae it...
Ports are open systems with direct connection to the sea, therefore any potential impact on port waters may have implications for health of adjacent marine ecosystems. European WFD addressed ports in category Heavily Modified Water Bodies (HMWBs) and promoted implementation protocols monitor improve their ecological status. TRIX index, which incorporates main variables involved trophism ecosystems (Nitrogen, Phosphorus, Chlorophyll a, Dissolved Oxygen), is widely utilized coastal areas...

Analysis of chlorophyll-a primary production dynamics in north Tyrrhenian Ligurian coastal–neritic ocean waters.Properly tuned algorithms based on optical remote sensing data can provide estimates (as a proxy for phytoplankton biomass) concentration near real time, allowing the monitoring both neritic oceanic areas. The main objective this study was, through use color satellite images, to offer...
Phytoplankton absorption is mainly determined by pigment composition and packaging into the cell, in turn affected concentration cell size shape. The variations of chlorophyll-specific coefficients at two selected wavelengths (443 nm 675 nm) were analysed for offshore areas Mediterranean Sea (Alboran, Algerian, Tyrrhenian, Ionian Basins Sardinia Channel) investigated autumn 2006, 2007 2008. spatial distribution Tchl a, accessory pigments, structure taxonomic phytoplankton assemblages was...
Abstract We studied the distribution, size structure, growth, and diet of freshwater prosobranch Melanopsis etrusca in experimental natural population samples. This snail is endemic to isolated headwaters thermal springs central Italy. In recent times, several anthropogenic pressures such as water extraction stream contamination have caused declines local extinctions M. . Consequently, this species was included on IUCN Red List Threatened Species. The streams inhabited by had oligohaline...

Three algorithms based on MODIS imagery were evaluated for the estimation of Chlorophyll-a concentration ([CHL]) in Western Mediterranean Sea. The first algorithm (OC3M) is usually applied at global scale, while second (MedOC3), has been used basin. third (SAM_LT), specifically developed Ligurian and North Tyrrhenian Seas, here described applied, its updated version. three assessed through comparison with 240 sea [CHL] samples collected during 2002–2011 decade. results obtained show that...
This work presents the elemental, polysaccharide, and fatty acid compositions of benthic aggregates formed by filamentous brown alga Acinetospora crinita, which are widely spread on rocky bottoms Mediterranean Sea. The can be characterized as mineralized centers in regeneration nutrients recycling dissolved organic matter actively occur favor development an abundant phytoplankton community. Analyses stable isotopes C N display their marine origin could provide evidence processes that...
