Surveiller la mer pour lutter contre les déchets marins : entretien avec Sana Ben Ismail, partenaire tunisienne du projet COMMON
On board the Amilcar-Mahdia boat, the scientific team of INTSM (Institut National des Sciences et Technologies de la Mer), partner of the COMMON project, started to monitor the sea, a fundamentalactivity to investigate the state of health of our water and analyse the presence of microplastics. Coordinating the work, Sana Ben Ismail, professor in physicaloceanography and coordinator of the Tunisian pilot areas of COMMON project.
“As a partner in COMMON project, the INSTM intends to monitor microplastics in two pilot areas of the project, Monastir and Kuriat Island. Twocampaigns are plannedeachyear: one in Spring and one after the touristseason in October to assessits impact on the pilot area. Due to the health situation of COVID-19, the pre-seasoncampaign has been postponed for October 2020. However, a preparation (test) campaignwascarried out in early August”, tells Sana Ben Ismail.
“In parallelwith the monitoring of the surface microplastics, the observation of the floating marine litteriscarried out on board in addition to the Beach Monitoring campaigns on the pilot area'sbeaches. We are also planning to monitor the microplastics in the targetedspeciessuch as the sardines Sardinellapilchardus or the bug Boopsboops”.
Professor Ben Ismail, what are the results of the first monitoring carried out in August?
“The test campaigncarried out in August wasnecessary for the project team to becomefamiliarwith the pilot areas. A meeting with the project team washeldduringwhich the sampling stations werediscussed and thenvalidatedaccording to theirrelevance in the study area. Five stations werethussampledusing a Manta net of 200 micron, whichallowed us to test the feasibility of the sampling as well as the equipment. The samples of microplasticcollectedwerestored in ethanol 70 ° and willbeprocessedlater in order to studytheir composition.
In addition, weused a (RemotelyOperatedVehicle), a submarine for the oceanstudy and alsousing to assess the situation of plastic pollution in the pilot area'sbottom.
Whyisit important to monitor at sea?
Seaobserving and monitoring are basic advancestowardstending to explicit inquiriesconcerning marine litter, includingmicroplastics. They are expected to survey the state or level of contamination and givetarget data to plan measures as well as to evaluatetheirviability to promote a management plan with a real impact. Monitoring helps to understand the type and origin of marine litter, the identification of hotspots as well as to study the impacts on biodiversity, humanhealth, seafoodsafety and tourism in order to set targets for reductionmeasures of marine litter.
Whatotheractivities are youdoingwith the INSTM within the COMMON project?
The INSTM isworking on training activities for local stakeholders to introduce marine litter management, on proposal of actions for developing public policies for an improved management of marine litter and, finally, we are involved in the creation of a coastalcities network against marine litter.
In addition, we are involved in the main awarenessactivitiesprovided by the project: the BEachCLEANcampaign withtouristoperators in Monastir region, and the 27th edition of Clean Up the Med, the biggestbeachcleaningcampaign in the Mediterraneanwhichwillbringtogether local bodies, the institutions, the NGOs and the citizensbelonging to COMMON's partner countries around the same objective: make the Mediterraneancleaner.
