Monitoring strategy description |
Main drivers for hydrographic changes are natural climate variability modified by climate change and infrastructure interventions in the coastal zone. Temperature, salinity, transparency and wave measurements strategy will be focused on selected oceanographic zones sufficient to distinguish natural climate variability from human impact. The measurements will be part of national monitoring of coastal waters. |

Gaps and plans |
During implementation phase, good environmental status is achieved. Some issues are recognised as weak points: cumulative effect of minor impact of constructions near coast and illegal human activities. The spatial-temporal resolution of the wave measurements are week and additional effort must be invested to find the most appropriate way to obtain relevant data and / or new methods to estimate them. |

Programme description |
Sea level monitoring is quite important for assessing environmental state of the Adriatic Sea, including potential changes in hydrographic conditions which are being reflected in sea level differences over the basin. Also, sea level changes are an indicator of man-mad pressures on the system, including climate change, which are predicted to be quite strong over the Adriatic and Mediterranean Seas. |
Sea currents would be measured in the following ways:
- Self-contained current meters. Current meters will be anchored at the bottom of the sea, protected in metal and concrete housing. Installation and extraction of the electricity meter will be performed every 6 months.
- Current meters installed on research ships. Marine current meters will be included during each exploration cruise and will measure the vertical current profiles along the route of research ship movement .
- high frequency radars. There will be two HF radar stations positioned so that the measurements cover the area in which the GES is monitored, and by a combination their measurements will yield continuous measurements of surface sea currents. |
In the Adriatic Sea, spatially and timely significant changes in the temperature, salinity and transparency are key parameters that determine dynamics of ecosystems.In the Adriatic Sea, the observed significant changes in temperature and salinity, and hence the change of water masses and thermohaline circulation have been caused by sudden change of climate in the northern hemisphere. These changes can have permanent effects on the ecosystem by changing the composition and relationships in the food chain. The consequences of these changes are different along the coast and on the open seas because the hydrographic conditions are different. |

Monitoring details |
Sea level will be measured continuously at tide gauges located in Stari Grad (island of Hvar), Vela Luka (island of Korčula) and Sobra (island of Mljet), with a time resolution of 1 minute. |
Along the Split - Gargano profile, current measurements using ADCP Acoustic doppler curren profiler installed on the research the ship would be performed once a month (12 times a year), or simultaneously with the measurements of temperature, salinity and transparency on the specified profile. Measurements by automatic measuring systems and instruments for measuring surface currents would be performed continuously with
with a time resolution of at least 1 hour. |
Temperatures, salinity and transparency will be measured in coastal waters four times a year, and more often if necessary, and certainly as much as predicted by Descriptor D5, along the Split - Gargano profile (Palagruža profile) measurements would be performed once a month (10 times a year) , and in the South Adriatic and on the Jabučki profile measurements would be carried out 4 times a year (seasonally). In the northern Adriatic at the eastern stations of the profile from Rovinj to the mouth of the river Po measurements should
perform at least 6 times a year, and more often if necessary, and certainly as much as provided by Descriptor D5. The amount of suspended matter will be sampled in the surface and bottom layers of the water column and at a depth of 10 m during field trips. |
