GRSE to build ocean research vessel in collaboration with NCPOR

Defence PSU Garden Reach Shipbuilders and Engineers Limited (GRSE) signed a contract with the National Centre for Polar and Ocean Research (NCPOR) for constructing an ocean research vessel, an official said on Wednesday. The contract, worth approximately Rs 840 crore, was signed between GRSE and NCPOR officials for the construction of the vessel in 42 months, the shipyard informed the stock exchanges. The Kolkata-headquartered warship builder said it has the necessary expertise in the field of survey vessels and has been building them for the Indian Navy for nearly four decades now. The contract was signed by the officials of the shipyard and NCPOR in Goa on Tuesday, the GRSE official said in a statement. In December 2023, GRSE delivered the INS Sandhayak, the largest survey vessel to be built in the country, to the Indian Navy. Three more vessels of this class are at various stages of completion at the shipyard, he said, adding that this experience will stand GRSE in good stead wh

A yr after Titan's dive, deep-sea explorers vow to pursue ocean's mysteries

The deadly implosion of an experimental submersible en route to the deep-sea grave of the Titanic last June has not dulled the desire for further ocean exploration, despite lingering questions about the disaster. Tuesday marks one year since the Titan vanished on its way to the historic wreckage site in the North Atlantic Ocean. After a five-day search that captured attention around the world, authorities said the vessel had been destroyed and all five people on board had died. Concerns have been raised about whether the Titan was destined for disaster because of its unconventional design and its creator's refusal to submit to independent checks that are standard in the industry. The US Coast Guard quickly convened a high-level investigation into what happened, but officials said the inquiry is taking longer than the initial 12-month time frame, and a planned public hearing to discuss their findings won't happen for at least another two months. Meanwhile, deep-sea exploration ...

India to become sixth country to have deep sea mission, says Jitendra Singh

Union Earth Sciences Minister Jitendra Singh on Sunday said India is set to become the sixth country to have its own deep-sea mission. Chairing a meeting to discuss the ministry's 100-day action plan, Singh expressed pride and happiness on the progress of the deep-sea mission and India being among the very few nations to achieve this feat. He asked institutes to focus on achieving a resilient blue economy to empower people dependent on the ocean and its energy for livelihood. Singh said the deep-sea mission is not limited to mineral exploration but development of ocean sciences and exploration of flora and fauna and conservation of marine biodiversity. He lauded the National institute of Ocean Technology's (NIOT) efforts for the development of Matsyayaan 6000, which can dive 6,000 metres deep into the ocean. Taking stock of the progress, he directed officials to complete the first stage of the vessel's harbour trial by September and finish the subsequent ones by 2026. Singh ...

Sea water recedes more than usual in Alappuzha leaving seabed exposed

A stretch of the coast near Alappuzha witnessed an unusual phenomenon on Tuesday, where the sea receded from its usual shoreline, leaving a portion of the seabed exposed. The sea receded approximately 50 metres along a half-kilometre stretch from Purakkad to Ayyankovil near Ambalappuzha, raising concerns among the fishing community. The affected area, now filled with sludge, has hindered their ability to embark on fishing ventures. Local MLA H Salam, along with other public representatives, visited the site to assess the situation. Official sources said district revenue officials visited the area and attributed this occurrence to the "chakara," a distinctive marine phenomenon characterised by the congregation of numerous fish and prawns during specific seasons, often coinciding with mud bank formations.

India's Samudrayaan set to explore ocean bed by 2025 end: Kiren Rijiju

India should be able to send its scientists to study the deep ocean 6 km under the sea surface in its own Samudrayaan by the end of next year, Earth Sciences Minister Kiren Rijiju has said. In a video interview to PTI, Rijiju said India's deep-ocean submersible Matsya6000, which will take humans up to a depth of 6,000 meters under the sea, was "well on course" and could be tested by the "end of this year". "When you talk about Samudrayaan, you are now talking about our mission to go up to around 6,000 meters, 6 km deep inside the ocean, where even light cannot reach. I can say that as far as our Matsaya, the machine which will take human beings inside, (is concerned), it's well on course," Rijiju said. The minister said he had reviewed the project and scientists should be able to carry out the first shallow water testing by the end of this year. "But broadly I feel confident that by the end of 2025, that means next year, we should be able to send our human crew to the deep ocean, m

CSIR-NIO launches advance underwater vehicle to monitor coral reefs

The Goa-based CSIR-National Institute of Oceanography (NIO) has launched an autonomous underwater vehicle called C-bot, a robot with advanced features for increased surveillance over the coral reefs. Council for Scientific and Industrial Research (CSIR) Director General Dr N Kalaiselvi launched the C-bot on Sunday and said the vehicle can travel to a depth of 200 metres underwater. This robot is the first step to building a capable underwater vehicle that can scan the depth of the Indian Ocean, she told reporters on the CSIR-NIO campus on Monday. Kalaiselvi said they plan to develop this vehicle further which will be able to travel thousands of metres in the sea. CSIR-NIO Director Sunil Kumar Singh said the C-bot will help in maintaining surveillance over the coral reefs in the ocean. He said that coral bleaching is taking place because of the climate change. "With different sensors, different cameras, the robot measures what the parameters are, and might help explain why the cor

Science packed 2024: Human spaceflight tests, deep ocean exploration

After the momentous landing on the moon's south pole, India has now set its sights on more challenging missions -- sending humans to space and getting samples from the lunar surface back to earth. Test flights for both the projects are scheduled in the new year. For Indian scientists it is just not about the moon and beyond. Furthering deep ocean exploration, the country is scheduled to send aquanauts on board the "Samudrayaan", first to a depth of 500 metres in March, and later, achieve its targeted depth of up to 6,000 metres. The Indian Space Research Organisation (ISRO) is set to begin the new year with the launch of XPoSat.? The X-Ray Polarimeter Satellite (XPoSat)? will seek to unravel the mysteries of the sources of X-Rays and study the enigmatic world of black holes. The satellite is set for launch on January 1 on board the Polar Satellite Launch Vehicle (PSLV) from Sriharikota. This would be followed by the insertion of the Aditya L-1 satellite at the Lagrange Point-1 on .

High ocean temperatures harming Florida coral reef, crews race to help

Steps away from the warming waters of Florida Bay, marine biologist Emily Becker removed covers from the dozens of water-filled tanks under her watchful eye. Nestled in seawater carefully maintained at about 85 degrees Fahrenheit (29 degrees Celsius) lay hundreds of pieces of coral some a sickly white from the bleaching that threatens to kill them, others recovered to a healthy bright iodine in colour. As Becker looked over the coral, crews of reef rescue groups arrived in trucks carrying more brought up by divers in a massive effort aimed at saving the coral from an ocean that is cooking it alive. People jumped into action really quickly, as best as they could, Becker said, wiping sweat from her brow. Up and down the chain of islands that form the Florida Keys, coral rescue groups and government and academic institutions have mobilized to save the coral from a historic bleaching event that experts say threatens the viability of the third-largest reef tract in the world. They've

Cargo ship carrying nearly 3,000 cars catches fire in north sea, 1 dead

A fire on a freight ship carrying nearly 3,000 cars was burning out of control Wednesday in the North Sea, and the Dutch coast guard said one crew member had died, others were hurt and it was working to save the vessel from sinking. Boats and helicopters were used to get the 23 crew members off the ship after they tried unsuccessfully to put out the blaze, the coast guard said in a statement. Currently there are a lot of vessels on scene to monitor the situation and to see how to get the fire under control," Coast Guard spokeswoman Lea Versteeg told The Associated Press in a telephone interview. "But it's all depending on weather and the damage to the vessel. So we're currently working out to see how we can make sure that ... the least bad situation is going to happen. Asked if it was possible the ship could sink, Versteeg said: It's a scenario we're taking into account and we're preparing for all scenarios.

Ocean currents regulating climate could collapse mid-century: Study

Collapse of ocean currents, that redistribute temperatures and precipitation between the tropics and the North Atlantic, is predicted to happen around mid-century if current greenhouse gas emissions persist, new research has found. Shutting down these currents could have serious consequences for the Earth's climate, such as a colder future for Europe, increased warming in the tropics and increased storminess in the North Atlantic region, the research published in Nature Communications journal said. The currents, called the Atlantic Meridional Overturning Circulation (AMOC), is estimated with high certainty to collapse in this century and most likely to occur in 2057, the analysis from the University of Copenhagen, Denmark, found using advanced statistical tools on ocean temperature data from the last 150 years. "Our result underscores the importance of reducing global greenhouse gas emissions as soon as possible," said Peter Ditlevsen, co-corresponding author of the study. The AMOC

US rejects plea to release radioactive water from nuclear plan into sea

Massachusetts environmental regulators have denied a request by the company dismantling a shuttered nuclear power plant to release more than 1 million gallons (3.8 million litres) of radioactive wastewater into Cape Cod Bay. The state Department of Environmental Protection's draft decision issued Monday said it denied Holtec's request for a permit modification because the discharge from Pilgrim Nuclear Power Station in Plymouth would violate a state law that designates the bay as an ocean sanctuary. The draft will not be finalised until after a public comment period that ends Aug. 25. Environmentalists and politicians praised the decision. Release of the treated wastewater would pose a threat to the bay's environment, human health, the fishing and shellfishing industries, and the economy of the region, Andrew Gottlieb, executive director of the Association to Preserve Cape Cod, said in a statement. Holtec sought to profit at the expense of the people, the environment and economy o
