It’s mid-morning on a sunny day and Yvette Yaa Konadu Tetteh’s arms and legs barely make a splash as she powers along the blue-green waters of the River Volta in Ghana. This is the last leg of a journey that has seen Tetteh cover 450km (280 miles) in 40 days to become the first person known to swim the length of the waterway.

It’s an epic mission but with a purpose: to find out whatis in the water and raise awareness of pollution in Ghana…

We Traced the Forever Chemicals Getting Into Ocean Ecosystems – the Conversation

PFAS, the “forever chemicals” that have been raising health concerns across the country, are not just a problem in drinking water. As these chemicals leach out of failing septic systems and landfills and wash off airport runways and farm fields, they can end up in streams that ultimately discharge into ocean ecosystems where fish, dolphins, manatees, sharks and other marine species live…

The World Is Running Out of Male Sea Turtles – Science Alert

Green sea turtles are already an endangered species, mainly due to humans hunting them, harvesting their eggs, degrading their habitats, or entangling them in garbage of some kind. But they also face another, more insidious threat from people: the loss of male hatchlings from the species…that this is partly caused by rising temperatures due to climate change – but a new study has now unveiled another human-caused problem driving this trend. Certain pollutants may promote feminization in sea turtles, explains lead author Arthur Barraza, a toxicologist with the Australian Rivers Institute at Griffith University…

Skimming vessels are working to contain and recover oil from a spill in the Gulf of Mexico off the Louisiana coast, which the U.S. Coast Guard on Tuesday estimated to be at least 1.1 million gallons. The spill was discovered Thursday near a 67-mile pipeline operated by the Main Pass Oil Gathering Co., owned by Houston-based Third Coast Infrastructure, and the Coast Guard said it was still reviewing whether that pipeline was the source of the contamination…

Research Confirms Link Between Snow Crab Decline and Marine Heatwave – NOAA Fisheries

“During the marine heatwave, snow crabs faced a triple threat,” said lead author and Alaska Fisheries Science Center stock assessment scientist Cody Szuwalski. “Their metabolism increased, so they needed more food; their habitat was reduced so there was less area to forage; and crabs caught in our survey weighed less than usual. These conditions likely set them up for the dramatic decline we saw in 2021…”
