Marine pollution management requires identifying all sources of contaminants, yet shipping's role in marine contamination remains unexplored. To address this gap, we investigated shipping contribution to water and air pollutant loads the Northern Adriatic Sea 2018 under two future scenarios. The approach integrated (i) modelled data shipping-related emissions, (ii) load from tributaries, (iii) land-based emissions atmosphere. results showed that significantly contributes copper, zinc (from antifouling paints), nitrogen sewage food waste), phenanthrene, naphthalene scrubbers bilge water) loads. Under an increased traffic scenario by 2050, scrubber use reduces atmospheric but increases pollutants, while alternative fuels reduce contaminants emission with no significant increase pollution.

The article analyzes the development of air temperatures and precipitation on two remote islands in Adriatic Sea from 1961 to 2023, examining annual monthly time scales. Lastovo Island is located southern Adriatic, Lošinj situated 277 km north, both exhibit a sharp rise since 1998, though series show no significant trends an increase or decrease. Using New Drought Index (NDI) method, this study calculated drought intensities for period 1961–2023. analyses conducted undoubtedly indicate rising frequency intensity droughts, with severe droughts doubling extreme increasing fourfold recent (1998–2023) compared previous one (1961–1997). most pronounced occurs specifically June August. This trend likely applicable many small Mediterranean Islands, which number over 10,000 have permanent population more than 1.6 million people, numbers significantly during tourist season. increased water demand agriculture daily use, combined risk, not only exacerbates potential forest fires but also threatens social structures ecological conditions. particularly critical as combination drier conditions fire risk poses challenge, endangering natural landscapes valuable historical sites that are integral islands’ identity heritage. study’s findings dangerous persist worsen continued increases region.

In the open ocean, marine heatwaves (MHWs) have been associated to a decline of Chlorophyll-a (Chl-a) concentration in tropical and temperate areas while, at higher latitudes, they seem enhance phytoplankton productivity. Currently, uncertainties remain on outcomes MHWs primary production coastal heterogenous regions. We analyzed long-term modeled satellite-derived data sea surface temperature Chl-a Adriatic Sea (Mediterranean Sea), semi-enclosed basin where open-sea environmental conditions co-occur, explore responses MHWs. found that both low high anomalies were strictly dependent MHWs, although following direct or inverse relationships different areas, as consequence regional-scale heterogeneities nutrient availability, riverine inputs, circulation geomorphology. Along west coast shallow North Central Adriatic, frequency, duration intensity corresponded frequency peaks and/or increased anomalies, suggesting pronounced fluctuations with intense blooms alternating extremely events. Conversely, offshore deeper especially South inversely correlated indicating possible reduction biomass organic matter flow towards floor.

This study examined shipping's impact on air and water quality in the Northern Adriatic Sea using high-resolution models. Studied pollutants included cadmium, lead, benzo-a-pyrene, fluoranthene, ozone, sulphur dioxide, nitrogen oxides, particulate matter (PM2.5). Shipping emissions, estimated via Ship Traffic Emission Assessment Model (STEAM), were integrated with land-based emissions to simulate ChemicalDrift System for Integrated modeLling of Atmospheric coMposition (SILAM) contribution sediments pollution is concentrated along shipping lanes, especially early summer. contributes significantly SO2 NOx levels near harbours while O3 PM2.5 changes affect entire area.
