Offshore wind power cables can affect sensory system of sharks and rays: studies

As offshore wind farms expand rapidly in the global renewable energy transition, scientists are studying how these large marine infrastructure projects affect ecosystems beneath the waves. Research from Wageningen University & Research in the Netherlands suggests that offshore wind may bring both risks and benefits for sharks and rays, known collectively as Elasmobranchii, which are highly sensitive to electromagnetic fields (EMFs). A six-year project called β€œElasmopower” examined how EMFs from subsea power cables in offshore wind farms affect bottom-dwelling sharks and rays. These species depend on natural electric and magnetic fields for key behaviors such as navigation, prey detection, habitat use and long-distance movement, particularly in low-visibility environments. The studies conducted as part of the Elasmopower project have been published in four papers, with three additional papers currently undergoing peer review. Sharks and rays have specialized electroreceptors called ampullae of Lorenzini. The jelly-filled sensory canals around the head and snout can detect even extremely weak EMFs from prey and predators, water movement, and the Earth’s geomagnetic field, Erwin Winter, a scientist at Wageningen, told Mongabay. This system is central to hunting and orientation, making Elasmobranchii especially relevant for studying EMF exposure from offshore energy infrastructure, Winter added. Erwin Winter, a researcher with the Elasmopower project, presented findings on offshore wind, electromagnetic fields and bottom-dwelling sharks and rays at the Sharks International 2026 conference in Colombo, Sri Lanka, in May.

The race for oil: will Jamaica be the next country to drill and what does that mean for its green pledges?

With early tests suggesting the presence of crude oil, the Caribbean island has begun to debate whether it could justify becoming a producer

Jamaica is closer than ever to drilling for oil. Tests on samples from the seabed off the Caribbean island’s south coast earlier this year identified hydrocarbons, which suggest the presence of crude oil below ground.

Jamaica imports all its fuel, which costs about $1.5-2bn (Β£1.1bn-1.5bn) annually, depending on global oil prices. It is a persistent drag on an economy that generated $4.3bn from tourism, its biggest earner, in 2024.

Do kangaroos form longterm relationships?

While kangaroos are a very social species, there has until recently been no evidence that they form long-term relationships between individuals. But a new study by researchers from UNSW Sydney indicates that this...
