A technological probe carried retired by the Centre for Marine Living Resources and Ecology (CMLRE), Ministry of Earth Sciences, has confirmed that the sinking of the instrumentality vessel MSC Elsa 3 off the Kerala seashore connected May 25, 2025 has led to important ecological disruption successful the south-eastern Arabian Sea.
The shipwreck impacted h2o quality, plankton, benthos, food eggs and larvae, and higher marine life. The persistence of lipid adjacent aft respective days, contempt prevailing turbulence and existent flows, highlighted the hazard of continued leakage. The survey underscored the urgent request for sealing of the wreck’s substance compartments and semipermanent monitoring of the impacted portion to safeguard marine ecosystems and fisheries resources, according to a communication.
The probe cruise on-board FORV Sagar Sampada was carried retired from June 2 to June 12, 2025, covering 23 sampling locations betwixt Kochi and Kanyakumari, with person observations adjacent the wreck site.
The investigation of PAH (Polyaromatic hydrocarbons) fractions revealed the beingness of compounds specified arsenic naphthalene, fluorene, anthracene, phenanthrene, fluoranthene, and pyrene. The elevated levels of naphthalene, which usually bespeak human-induced contamination, powerfully suggested leakage from the wreck’s substance compartments. In addition, higher concentrations of hint metals commonly associated with petroleum, including nickel, lead, copper, and vanadium, were detected successful some h2o and sediments adjacent the site. These findings confirmed that the wreck has go a section root of hydrocarbon and heavy-metal pollution, it said.
Impact connected marine fauna
The survey recovered that ample numbers of food eggs and larvae collected from the affected country showed signs of decay, suggesting imaginable mortality linked to lipid vulnerability during this susceptible stage. On the seafloor, benthic organisms showed wide signs of ecological stress.
Sensitive taxon declined sharply wrong days of the incident, leaving down lone pollution-tolerant worms and bivalves. This displacement indicates acute disturbance of the seabed, with imaginable semipermanent consequences for sediment wellness and fisheries habitats, according to the communication.
The probe revealed disposable impacts extending to higher marine fauna arsenic well. A Brown Noddy seabird (Anous stolidus) was observed taking prolonged structure connected the wreck, repeatedly preening its feathers, a emblematic behavioural effect to lipid contamination of plumage. Such incidents constituent towards the vulnerability of marine birds and higher organisms successful the vicinity of the spill.
