“…36 (Italy) (112 and 107 dB re 1 µPa at 63 Hz and 125 Hz TOB, respectively); in this case, data were collected at the extreme water depth of 2100 m. Recently, hourly 63 and 125 Hz TOB median values have been found mostly between 90 and 105 dB re 1 µPa during the winter period (November-March 2019): here37 , acoustic data were recorded at 1,000 m depth in the South-eastern Adriatic Sea, to the South of Split (MS8), approximately at 20 km west of Dubrovnik (Croatia).Monthly averaged SPLs ranged between 92 and 115 B re 1 µPa at 63 and 125 Hz TOBs in the yearly measurements in the port of Cartagena 38 (Spain) and median SPLs from 91 to 98 dB re 1 µPa at 63 Hz and 125 TOB s were recorded at the Gulf of Naples 39 along three months period (Italy), both areas being under intensive urban settlements and maritime tra c. These sound levels are comparable to the SOUNDSCAPE levels recorded in port areas as Split (MS8) and the Trieste Gulf (MS4). Continuous shorttime assessment run in the Trieste Gulf indicated also daily SPLs ranging between about 65 and 120 dB re 1 µPa at the 63 Hz and 125 Hz TOBs inside the Natural Marine Reserve of Miramare40 and average levels between 83 and 101 dB re 1 µPa at 63 Hz and 125 Hz TOBs in the Slovenian waters41 .…”

Anthropogenic underwater noise is an emergent pollutant and several monitoring programs have started worldwide. However, only few data are available so far for the Mediterranean Sea, one of the global biodiversity hotspots. To fill this knowledge gap, this study presents the results of the first continuous acoustic monitoring run at a transnational basin scale in the Mediterranean Sea between March 2020 and June 2021, including the COVID-19 lockdown, at nine stations in the Northern Adriatic Sea. Median yearly sound pressure levels (SPLs) ranged between 64 and 95 as well as 70 and 100 dB re 1µPa for 63 and 125 Hz third octave bands, respectively. Although these values are comparable with those previously found in busy shallow EU basins, higher levels are likely to be found during a business-as-usual period. Higher and more variable SPLs, mainly related to vessel traffic were found in stations close to important harbours, whereas stations inside or close to Natura 2000 sites, experienced lower SPLs, and lower values were recorded during the Covid-19 lockdown in four stations. This represent the first baseline acoustic assessment for a highly impacted and valuable area that needs to be taken into account in a new sustainable blue growth strategy.

“…The Adriatic Sea is also one of the Mediterranean areas most exposed to geoseismic surveys (Maglio et al, 2016). Such surveys have been conducted throughout the basin, including in very shallow waters, and noise emissions can be frequent and long-lasting (Carniel et al, 2012;De Santis and Caldara, 2016;Trobec et al, 2018;Brancolini et al, 2019;Giustiniani et al, 2020;Širović and Holcer, 2020), raising concern about their effects on cetaceans, particularly deep-diving species such as the Cuvier's beaked whale. Several military areas exist in the Adriatic, but risks related to the possible use of military sonars (that were linked to a mass stranding of Cuvier's beaked whales in western Greece; Frantzis, 1998) are unknown.…”

The Adriatic Sea is one of the Mediterranean areas most exposed to cumulative human stressors. This semienclosed and largely shallow basin has been subjected to intensive exploitation and destructive fishing practices for decades, resulting in biodiversity decline and poor ecosystem health. Diversity of cetaceans is lower than in other parts of the Mediterranean, and the extant dolphins and whales have been facing threats that include the combined effects of habitat loss and degradation, prey depletion, incidental mortality and injury caused by fisheries, anthropogenic noise, chemical contamination and climate change. Here, we report information for the nine cetacean species known to occur in the basin (classified as either regular, visitor or vagrant), plus three species characterized by a single record. For these species, we review evidence from field research and other studies – with a bias towards the common bottlenose dolphin Tursiops truncatus (by far the most intensively-studied cetacean in this area). We also describe and characterize the main threats to cetaceans in the Adriatic, relying on recent literature as well as historical information that helps frame the present status of cetaceans in the context of past human impacts (particularly the extensive killing campaigns conducted until the 1960s). Finally, we provide management recommendations to inform and guide the action that must be taken in compliance with extant legislation, marine conservation directives and international commitments to protect marine biodiversity.

“…SOUNDSCAPE aims to establish joint monitoring, carry out a transnational noise assessment, and implement a planning tool for noise management. Various localised MSFD monitoring studies have also been carried out in the Mediterranean, notably in Italy (Codarin and Picciulin, 2015;Viola et al, 2017;Cafaro et al, 2018;Pieretti et al, 2020), Croatia (Rako et al, 2013;Picciulin et al, 2016;Vukadin, 2016), Montenegro ( Širović and Holcer, 2020), Greece (Prospathopoulos et al, 2017), and Slovenia (Popit, 2021).…”
