2. ADIOS motivation
Long-term monitoring in the Adriatic has been declined during recent years. The last remaining transect at the Palagruža Sill has been just partially surveyed a few times between 2013 and 2016.
There were a number of field campaigns in the Adriatic in recent years, which imho should be merged and better exploited in term of process-level studies (like DWF or other).
Assessment of regional ocean climate models has not been performed for the Adriatic – the most of validation studies has been concentrated to the Gulf of Lions and Western Mediterranean.
It is a question if present climate models have appropriate resolution, forcing, setup, ..., to reproduce highly transient and variable Adriatic phenomena such as bora wind, DWF, coastal sea-breeze circulation, coastal upwelling or other.

3. ADIOS facts
Project Title: The Adriatic decadal and interannual oscillations: observations, modelling and consequences (ADIOS)
Principal Investigator: Ivica Vilibić
Funding: Croatian Science Foundation
Budget: ,00 HRK (1/3 to ADIOS cruises, 1/3 to two-year postdoc, 1/3 to everything else)
Project Duration: 20 March 2017 – 19 March 2021
Involved researchers (formal): Ivica Janeković (IRB, HR), Samuel Somot (CNRM, FR), Manuel Bensi (OGS, IT), Vedrana Kovačević (OGS, IT), Darko Koračin (PMFST, HR), Clea Denamiel (IOF, HR), Natalija Dunić (IOF, HR), Slavko Radilović (PMFST, HR), Hrvoje Mihanović (IOF, HR), Jadranka Šepić (IOF, HR)
Involved researchers (informal): everybody is invited :) so far, interests from Tomislav Džoić, Frano Matić, Ivan Güttler, we have one SeaTech student working on the project, ...

4. ADIOS structure Five research modules:
Maintaining and assessing long-term field observations in the Adriatic
What we need: seasonal cruises
ADIOS: two/one time(s) per year

5. ADIOS structure Dense-water formation studies
Studies based on ESAW/IOF/NAdEx2015/BIOTA/E2-M3A/ARGO/glider/satellite/... data in the central and middle Adriatic and numerical modelling

6. ADIOS structure
Assessing performances of present climate ocean models in the Adriatic
Med-CORDEX and other simulations to be assessed vs. long-term observations in the Adriatic and vs. processes that drive Adriatic thermohaline circulation (DWF, BiOS, ...)
Mostly related to Natalija’s PhD research.

7. ADIOS structure
High-resolution hindcasting of the Adriatic past climate
High-resolution projections of the Adriatic future climate
How far we can go? That’s to hear in Clea’s presentation.
Once finished, these simulations will allow for significant advancing in knowledge of a number of atmospheric and ocean processes, both over transient and long-term scales: DWF, THC, bora, sea-breezes, coastal upwelling, ... high-risk high-gain game :)
