A simulation using the search and rescue aid tool (SARAT) run by INCOIS, Hyderabad, shows that the nurdles are likely to drift further along the coast near Sattankulam by Saturday evening, before moving southward and offshore on Sunday.
The tiny plastic pellets, used in plastic manufacturing, had already started washing ashore in Kanyakumari district on Wednesday.
"In 36 to 48 hours, the nurdles are likely to move offshore because the currents in that area are directed away from the coast.
However, due to wind patterns, a portion of the spill could drift into the Gulf of Mannar. But the majority is expected to reach Sri Lanka's west coast," said Balakrishnan Nair T M, Director, INCOIS.
The container vessel MSC Elsa-3 sank on May 25, about 38 nautical miles (about 70 km) off the Kerala coast, between the ports of Vizhinjam and Kochi.
The ship was carrying 640 containers, including 13 with hazardous materials such as calcium carbide, along with 84.44 tonnes of diesel and 367.1 tonnes of furnace oil.
On Friday, chief minister M K Stalin chaired a meeting with officials on the safety measures to be taken to remove nurdles and other hazardous waste from the Elsa-3 shipwreck.
According to a release from the state govt, Stalin inquired of environment and forest department secretary Supriya Sahu whether there was any oil spill from the ship accident and whether the marine organisms were affected.
Sahu informed him that the pollution control board officials were inspecting if there was any oil spill and that they had contacted the ship authorities to determine whether there were any hazardous substances onboard the ship.

Veterinary and fisheries department secretary N Subbian told Stalin that he directed the fisheries officials to check whether the marine organisms were affected by the shipwreck and whether nurdles have been ingested by marine organisms.
The fishermen were also advised to avoid fishing in the affected areas, Subbian told Stalin.
Stalin directed the officials to monitor the movement of nurdles according to climatic conditions and to check the possible coastal areas where nurdles might get washed away.
The district collectors of Kanyakumari, Tirunelveli, Tuticorin, and Ramanathapuram were already briefed by the state disaster response authority about the steps to be taken to remove nurdles.

Plastic nurdle spill threatens 'Malabar' upwelling region
The sinking of the Liberian-flagged MSC ELSA 3 off the Kochi coast in Kerala on May 25, has triggered an environmental crisis along the Kerala and Tamil Nadu coast because it spilled plastic nurdles—tiny pellets used in plastic manufacturing—into one of the world's richest 'Malabar' upwelling regions. Upwelling brings deep, cold water to the surface, propelled as they are by strong ocean currents and the rotation of the Earth. There are five major upwelling regions determined by seasonal ocean current upwelling systems — the Canary, Benguela, California, Peru and Malabar. The Malabar Upwelling Region (MUR) stretches from Ratnagiri in Maharashtra to Kanyakumari in Tamil Nadu. Although these regions form less than 1% of world's oceans, they contribute to more than 25% of fish catch. Each support a rich ecosystem and commercially important fisheries. These large marine ecosystems are increasingly under threat from over-exploitation, pollution and habitat modifications. The Kochi plastic nurdle spill falls bang in the middle of MUR. Carrying 640 containers, including 13 with hazardous materials, the shipwreck scattered nurdles onto beaches from Thiruvananthapuram to Kanniyakumari, threatening one of India's most biodiverse marine ecosystems. This marks the first major nurdle spill in India caused by a shipwreck, raising urgent concerns about ecological and economic repercussions. Experts say the spill occurred as the upwelling system was taking shape where monsoon-driven winds lift nutrient-rich deep waters to the surface. This process fuels plankton blooms, sustaining nearly 50% of India's marine fish landings, including small pelagic species like Indian Mackerel (accounting for 30% of marine landings, with India producing 90% of the global supply, 77% from the west coast) and oil sardines. The region's high productivity, driven by sea surface temperature, salinity, and mixed layer depth, supports a complex food web, linking plankton to larger predatory fish and providing livelihoods for lakhs of fishermen. The spill's timing during the monsoon upwelling period, when productivity peaks, heightens the risk of disrupting this delicate ecosystem.

Oil spill from sunk Liberian ship, ICG monitoring situation
Chennai, May 31 (UNI) The Indian Coast Guard (ICG) is closely monitoring the situation arising out of oil spill and plastic pellets in the sea along Tamil Nadu coasts after a Liberian ship sank off Kochi coast. A defence release here on Saturday evening said the Liberian-flagged Container Ship MSC Elsa 3 had sank off Kochi which was carrying 640 containers and #POL. "ICG had coordinated #Rescue of entire crew but numerous containers, debris, and plastic pellets (nurdles) were spilled at sea", it said. "Team #ICG East have been keeping close watch on the situation and coordinating response to these nurdles/other debris that have washed ashore along Tamil Nadu coasts at Colachel & Kanyakumari. A 40Ft Container has also washed ashore at Kodimunai Beach", it said. The ICG team were deputed to these sites for assisting the District Administration Teams towards the ongoing cleanup operations at Colachel and Kanyakumari to protect the Marine Environment, it said. Following the sinking of the ship, a total of 22 coastal villages across the Killiyoor and Kalkulam taluks in Kanniyakumari district have been affected by the debris that washed ashore, including a container. The vessel was carrying 640 containers, including 13 with hazardous cargo and 12 with calcium carbide and also had 84.44 metric tonnes of diesel and 367.1 metric tonnes of furnace oil. While the initial impact of the incident was felt along the coast of Kerala, plastic pellets, wooden logs, and cashew nuts have begun washing ashore in the villages of Kanniyakumari over the past three days. The district administration has opened a 24x7 control room to enable the public to report if any debris were found along the coast. Chief Minister M.K. Stalin also held a review meeting at the State Secretariat to discuss the steps for the removal of the debris that were washed ashore. Officials of the Revenue, Environment, Forest and Climate Change, Fisheries Departments and the Tamil Nadu Pollution Control Board took part in the meeting which discussed on the safe removal of plastic and other materials that have washed ashore and to prevent any harmful effect on the public and to assess the potential impact on marine organisms. Though no hazardous materials have washed ashore on the Tamil Nadu coast till date, the Chief Minister directed the authorities to coordinate with various departments and volunteers for the safe removal of the debris, besides conducting studies on both the short term and long term environmental impact on marine life.
