3. Best practice manual for national decade committeesstrokovna monografija Povzetek: 2023 marks the beginning of the third year of the UN Decade of Ocean Science for Sustainable Development, and we are now at a moment in time where we can start taking stock of the Ocean Decade’s early achievements. The critical role that National Decade Committees are playing at the junction of the global momentum of the Ocean Decade and the national transformation of ocean science is clear and extremely encouraging. I warmly congratulate those Member States that have led by example and created the first cohort of National Decade Committees. This Best Practice Manual for National Decade Committees is an opportunity to celebrate their dynamism, share their vision and successes, and encourage the establishment of new Committees across all 150 IOC/UNESCO Member States. The ambition of the Ocean Decade is to transform ocean science for the decades to come, thereby creating a step change in the relationship of all citizens to the ocean, and in the way that a healthy ocean contributes to sustainable development. National Decade Committees are essential to catalyse the transformation of ocean science by boosting national capacity to offer solutions to pressing challenges and working across the science-policy-society interface to inform decision makers and society at large. By bringing together diverse stakeholders and breaking down silos, National Decade Committees create a tangible and visible difference on the ground. Beyond their role to coordinate existing initiatives and catalyse new Decade Actions, National Decade Committees embody the core principles of the Ocean Decade including equity, inclusivity, and diversity, and the recognition of the importance of Indigenous and local knowledge systems. They have a particularly significant role in giving a seat at the table to Early Career Ocean Professionals, who will be the torch bearers of the legacy of the Ocean Decade post-2030.I hope that the diverse and rich experiences shared in this Manual will inspire many other Member States to actively participate in the Ocean Decade by setting up their own National Decade Committees. The existing cohort of National Decade Committees and the IOC/UNESCO stand ready to facilitate the involvement of new partners, while supporting the pioneers to go even further, and thus together achieve a key goal of the Ocean Decade to make sure no one is left behind in the endeavour to create the ocean we want by 2030.

4. A transdisciplinary co-conceptualisation of marine identityP. M. Buchan, L. D. Glithero, E. McKinley, M. Strand, G. Champion, Vesna Flander-Putrle, 2024, izvirni znanstveni članek Povzetek: 1. Challenge 10 of the United Nations Decade of Ocean Science for Sustainable Development (2021–2030) calls for the restoration of society's relationship with the ocean. Research suggests that the relationship people have with marine environments can influence their depth of engagement in marine citizenship action, and the important role for ‘marine identity’ in driving that action. Although identity is well-researched, marine identity is a concept novel to academia and a baseline understanding is required, both to grasp the scope of the concept, and to support research into its role in transforming the human-ocean relationship.
2. Here, a transdisciplinary study, endorsed as a UN Ocean Decade Activity and by the EU Mission Ocean & Waters, brought together a multinational community of marine researchers and practitioners to co-produce a baseline conceptualisation of marine identity, drawing on photovoice and deliberative methodology. This paper presents the findings of the co-production process and offers a first introduction in the literature of the multiple variations and formations of marine identity.
3. We find marine identity to be a complex and multidimensional concept, suffused with individual experiences and understandings of the marine environment, based on social and cultural understandings of the ocean, contemporarily and historically. We present real-world examples of marine identity to illustrate key themes that were developed through co-production.
4. Policy implications: We propose marine identity as a catalyst for understanding existing multifaceted and caring relationships with the ocean, as well as the restoration of society's relationship with the ocean. Marine identity research should, therefore, be prioritised in research seeking to contribute to the UN Ocean Decade Challenge 10, as this will support integration of non-material values of the ocean into marine planning processes and policy making, enabling effective responses to Challenge 10's emphasis on integrating traditional/cultural ways of knowing and valuing the marine environment, through diverse marine identities. We welcome research efforts that will further develop the marine identity concept and empirically investigate the relationships between marine identity, marine citizenship, and people's relationships with the ocean.

5. Določanje dobrega okoljskega stanja. Poročilo za člen 9 Okvirne direktive o morski strategiji : zaključno poročilo 2012Martina Orlando-Bonaca, Lovrenc Lipej, Alenka Malej, Janja Francé, Branko Čermelj, Oliver Bajt, Nives Kovač, Borut Mavrič, Valentina Turk, Patricija Mozetič, Andreja Ramšak, Tjaša Kogovšek, Milijan Šiško, Vesna Flander-Putrle, Mateja Grego, Tinkara Tinta, Boris Petelin, Martin Vodopivec, Maja Jeromel, Urška Martinčič, Vlado Malačič, končno poročilo o rezultatih raziskav Povzetek: Deskriptor 1: Biotska raznovrstnost se ohranja. Kakovost in prisotnost habitatov ter razporeditev in številčnost vrst so v skladu s prevladujočimi fiziografskimi, geografskimi in podnebnimi pogoji.
»Presojo je treba opraviti na več ekoloških ravneh: na ravni ekosistemov, habitatov (vključno z njimi povezanimi združbami na nivoju biotopov) in vrst, ki so upoštevane v strukturi tega dela ob upoštevanju točke 2 dela A. Za nekatere vidike tega deskriptorja je potrebna dodatna znanstvena in tehnična podpora. Pri obravnavi širšega obsega deskriptorja je treba ob upoštevanju Priloge III k Direktivi 2008/56/ES določiti prioritete med elementi biotske raznovrstnosti (vrste, habitati in ekosistemi). To omogoča prepoznavanje tistih elementov in območij, kjer vplivi in grožnje nastajajo, poleg tega pa podpira opredelitev ustreznih kazalcev med izbranimi merili, primernimi za zadevna območja in elemente biotske raznovrstnosti. Obveznost regionalnega sodelovanja iz členov 5 in 6 Direktive 2008/56/ES je neposredno povezana z izbiro elementov biotske raznovrstnosti znotraj regij, podregij in pododdelkov, kjer je mogoče, pa tudi z vzpostavitvijo referenčnih razmer v skladu s Prilogo IV k Direktivi 2008/56/ES. Modeliranje z uporabo platforme geografskega informacijskega sistema je lahko uporabna podlaga za določanje območja razširjenosti elementov biotske raznovrstnosti ter človekovih dejavnosti in pritiskov zaradi teh dejavnosti, ob upoštevanju, da se vse mogoče zajete napake ustrezno ocenijo in opišejo ob uporabi rezultatov. Ti podatki so pogoj za ekosistemsko upravljanje človekovih dejavnosti in za razvoj s tem povezanih prostorskih orodij.«

7. Nevarnosti v morju, ki večinoma to nisoVesna Flander-Putrle, Alenka Malej, Manja Rogelja, 2020, druge monografije in druga zaključena dela Povzetek: Morske trave niso alge, temveč spadajo med cvetnice. Od okoli 60 vrst, ki obstajajo na svetu, samo 4 izvorno uspevajo v Evropi – in vse najdemo tudi v slovenskem morju. To so: prava morska trava (Zostera marina), mala morska trava (Zostera noltii), kolenčasta cimodoceja (Cymodocea nodosa) in pozejdonka (Posidonia oceanica). Za vse so značilni tanki, ozki in dolgi listi. Pri nas tvori največje in najgloblje travnike kolenčasta cimodoceja (Cymodocea nodosa). Prisotnost morske trave je pokazatelj dobre kakovosti obalnega morja, travniki pa so pomemben habitat za številne organizme.

8. Signatures of pigments and processes in the south Adriatic Pit - project MEDUZAMira Morović, Vesna Flander-Putrle, Davor Lučić, Branka Grbec, Barbara Gangai, Alenka Malej, Frano Matić, 2012, izvirni znanstveni članek Povzetek: During two cruises of the MEDUZA experiment conducted in July 2003 and May 2005 various data were obtained over the deepest part of the southern Adriatic Pit. Temperature, salinity, light transmission and fluorescence were measured in July 2003. During May 2005, except CTD measure- ments the samples were taken for laboratory determination of phytoplankton pigments with HPLC technique. During both cruises irradiance and radiance were measured at 14 wavelengths in the range 340-715 nm with optical probe to about 100 m depth. Bad weather conditions during both cruises caused interruption of measurements that continued after 24 to 48 hours. Stormy conditions have resulted in a slightly different structure of the water column. In the periods of measurements recorded were diurnal rhythms in a series of parameters, caused by solar radiation cycles in the surface layers as well as fluctuations in the deeper layers under the influence of the internal tide. Meteorological conditions and changes in sea level are also described. The analysis included the principal component and correlation analysis between the measured and derived parameters in order to establish a link between the in-situ pigments and multispectral data. During both cruises diurnal vertical oscillations were observed in biotic and abiotic parameters. Chlorophyll pigments prevailed over other pigments preventing other pigments to be distinguished spectrally. Regression models for chlorophyll a were established from radiance and reflectance ratios.

9. Mixtures of Chemical Pollutants at European Legislation Safety Concentrations: How Safe are They?Raquel Negrão Carvalho, Augustine Aruqwe, Selim Ait-Aissa, Anne Bado-Nilles, Stefania Balzamo, Anders Baun, Shimshon Belkin, Ludek Blaha, Francois Brion, Daniela Conti, Vesna Flander-Putrle, Valentina Turk, 2014, izvirni znanstveni članek Povzetek: The risk posed by complex chemical mixtures in the environment to wildlife and humans is increasingly debated, but has been rarely tested under environmentally relevant scenarios. To address this issue, two mixtures of 14 or 19 substances of concern (pesticides, pharmaceuticals, heavy metals, polyaromatic hydrocarbons, a surfactant, and a plasticizer), each present at its safety limit concentration imposed by the European legislation, were prepared and tested for their toxic effects. The effects of the mixtures were assessed in 35 bioassays, based on 11 organisms representing different trophic levels. A consortium of 16 laboratories was involved in performing the bioassays. The mixtures elicited quantifiable toxic effects on some of the test systems employed, including i) changes in marine microbial composition, ii) microalgae toxicity, iii) immobilization in the crustacean Daphnia magna, iv) fish embryo toxicity, v) impaired frog embryo development, and vi) increased expression on oxidative stress-linked reporter genes. Estrogenic activity close to regulatory safety limit concentrations was uncovered by receptor-binding assays. The results highlight the need of precautionary actions on the assessment of chemical mixtures even in cases where individual toxicants are present at seemingly harmless concentrations.

10. Comparison of in-situ chlorophyll-a time series and sentinel-3 ocean and land color instrument data in Slovenian national waters (Gulf of Trieste, Adriatic Sea)El Khalil Cherif, Patricija Mozetič, Janja Francé, Vesna Flander-Putrle, Jana Faganeli Pucer, Martin Vodopivec, 2021, izvirni znanstveni članek Povzetek: While satellite remote sensing of ocean color is a viable tool for estimating large-scale patterns of chlorophyll-a (Chl-a) and global ocean primary production, its application in coastal waters is limited by the complex optical properties. An exploratory study was conducted in the Gulf of Trieste (Adriatic Sea) to assess the usefulness of Sentinel-3 satellite data in the Slovenian national waters. OLCI (Ocean and Land Colour Instrument) Chl-a level 2 products (OC4Me and NN) were compared to monthly Chl-a in-situ measurements at fixed sites from 2017 to 2019. In addition, eight other methods for estimating Chl-a concentration based on reflectance in different spectral bands were tested (OC3M, OC4E, MedOC4, ADOC4, AD4, 3B-OLCI, 2B-OLCI and G2B). For some of these methods, calibration was performed on in-situ data to achieve a better agreement. Finally, L1-regularized regression and random forest were trained on the available dataset to test the capabilities of the machine learning approach. The results show rather poor performance of the two originally available products. The same is true for the other eight methods and the fits to the measured values also show only marginal improvement. The best results are obtained with the blue-green methods (OC3, OC4 and AD4), especially the AD4SI (a designated fit of AD4) with R = 0.56 and RMSE = 0.4 mg/m³, while the near infrared (NIR) methods show underwhelming performance. The machine learning approach can only explain 30% of the variability and the RMSE is of the same order as for the blue-green methods. We conclude that due to the low Chl-a concentration and the moderate turbidity of the seawater, the reflectance provided by the Sentinel-3 OLCI spectrometer carries little information about Chl-a in the Slovenian national waters within the Gulf of Trieste and is therefore of limited use for our purposes. This requires that we continue to improve satellite products for use in those marine waters that have not yet proven suitable. In this way, satellite data could be effectively integrated into a comprehensive network that would allow a reliable assessment of ecological status, taking into account environmental regulations.
