Thailand Hopes Trackers Will Boost Conservation of Endangered Leatherback Turtles

Off the shore of Thailand's resort island of Phuket, marine conservationists have released 11 baby leatherback sea turtles into the Indian Ocean, hoping they can thrive in the wild and return in two decades to reproduce.The release of the year-old turtles, each about the size of a rugby ball, follows an intense conservation effort to boost the leatherback's survival chances after the discovery in 2018 that the endangered species had returned to lay eggs in southern Thailand.The stronger turtles have successfully made their way into the ocean, while others perished after hatching, so a programme

More Than 60% of World's Coral Reefs May Have Bleached in Past Year

Nearly two-thirds of the world's coral reefs have been subjected to heat stress bad enough to trigger bleaching over the past year, the leading agency monitoring coral reefs said on Thursday.The U.S. National Oceanic and Atmospheric Administration (NOAA) announced last month that the world's coral reefs were in the throes of a fourth mass bleaching event, as climate change combined with an El Nino climate pattern has pushed ocean temperatures to record highs.Now, the agency reports some 60.5% of the world's reef area has been affected and that number is still rising."I am very worried

Sea Turtle Hormone Levels Affected by Deepwater Horizon Oil Spill -Study

New research is revealing potential impacts on the hormones of sea turtles affected by the Deepwater Horizon oil spill in the Gulf of Mexico.The 2010 spill, the largest marine oil spill in history, is estimated to have exposed hundreds of thousands of sea turtles to oil and killed up to 86,500 juvenile Kemp’s ridley turtles, a critically endangered species. In the aftermath of the oil spill, 319 live sea turtles were recovered from the ocean and taken to rehabilitation facilities for medical assessment and treatment. Responders collected blood samples to assess the health of each turtle, and a

Scientists Discover Possible Hammerhead Shark Nursery in Ecuador's Galapagos

, in the Galapagos if confirmed, the park said.The smooth hammerhead is one of nine known species of hammerhead shark. It is considered "vulnerable" on the International Union for Conservation of Nature's list of threatened species.Scientists on a Greenpeace expedition toured the Galapagos Marine Reserve several weeks ago, spotting a young female hammerhead off of Isabela Island, the Galapagos' largest island, and tagging her.Researchers will continue to monitor the shark to confirm that she was in a breeding area.The Galapagos Islands with its unique wildlife was critical to British

Wave Measurement Technology Helps Protect Vietnam’s Coastal Population

The Mekong Delta in Vietnam is home to over 20 million people and acts as a globally important agricultural area. The health and longevity of this important ecosystem is being threatened by rising sea levels and coastal erosion.Researchers rely on advanced wave measurement devices from Nortek to validate ocean models and provide accurate data for the development of coastal erosion defenses.The Mekong Delta encompasses the southern tip of Vietnam and is home to some of the world’s most fertile land. Over past decades, this area has faced increasing environmental pressure.Upstream dams and sand

Greece to Spend 780 Million Euros to Protect Marine Biodiversity

Greece is pushing ahead with 21 initiatives worth 780 million euros ($830.9 million) to protect marine biodiversity and tackle coastal pollution, Prime Minister Kyriakos Mitsotakis said on Monday ahead of an international conference.Greece, which includes thousands of islands and which has the longest Mediterranean coastline of any littoral state, said last week it plans to create two marine parks, one in the Ionian Sea and one in the Aegean Sea, as part of the initiatives."Quietly but methodically, Greece is playing a leading role in the defence against dramatic climate changes, which are proven

MBARI Names Kaya Johnson Director of Marine Operations

MBARI recently welcomed Kaya Johnson as its new director of marine operations, tasked with overseeing the institute’s seagoing assets, including three research vessels, a deep-sea cabled observatory and fleet of advanced underwater robots.Johnson comes to MBARI from Oregon State University (OSU), where he worked for the past six years. Johnson was port captain at OSU, then served as marine superintendent of ship operations. He managed operations for OSU’s fleet of three research vessels—Elakha, Oceanus (retired in November 2021) and Pacific Storm.Prior to his tenure at OSU, Johnson

Coral Reefs Suffer Fourth Global Bleaching Event

in March, tropical reefs in the Pacific and Indian oceans also began to suffer.A record-breaking number of individual reefs within the Great Barrier have suffered from heat stress in recent months, and many are now draining of color, said coral biologist Neal Cantin at the Australian Institute of Marine Sciences. Cantin noted that marine heatwaves were registering some 2.5 C (4.5 F) above the normal summertime maximum.Recent aerial surveys have shown "very high" or "extreme" levels of bleaching in nearly half of surveyed reefs in the Great Barrier Reef Marine Park area.That makes
