It’s much harder to track the effects of the tens of thousands of chemicals that are dumped in the ocean every day, through sewage, agricultural runoff, and industrial waste—most of which have unknown effects on wild ecosystems. What we do know is that the bodies of marine animals act like magnets for these toxics, which accumulate in their fat and are amplified up the food chain.
“With the ocean warming, we saw a shift in the ecosystem and in the feeding behavior of humpback whales that led to a greater overlap between whales and crab fishing gear,” said Jarrod Santora, a researcher in applied mathematics at UCSC’s Baskin School of Engineering and first author of the study, published January 27 in Nature Communications.
A listening station on the channel floor is able to capture whale calls as far away as 30 miles (48 kilometers), the Los Angeles Times reported Friday. That device is connected by cable to a buoy floating above that transmits data by satellite to scientists on shore.
Recently, Rep. Joe Cunningham (D-SC) blasted a Trump official with an air horn. During a House committee hearing on the environmental impact of seismic airgun testing, the official claimed the practice isn’t disruptive to marine animals. That’s when Cunningham pulled… Read More ›

“The Trump administration has declared war on whales, dolphins and turtles off the coast of California,” Todd Steiner, director of the California-based Turtle Island Restoration Network, told the LA Times.
So far, 15 additional dead humpback whales have shown up along the east coast, bringing the total to 41. The high number led the National Oceanic and Atmospheric Administration (NOAA) to open an investigation into what is now officially classified as an unusual mortality event.
Entanglements have surpassed ship strikes as a leading danger to right whales in recent years. Forty-four percent of diagnosed right whale deaths were due to ship strikes and 35 percent were due to entanglements from 1970 to 2009, the study said. From 2010 to 2015, 15 percent of diagnosed deaths were due to ship strikes and 85 percent were due to entanglements, it said.
Each year around 650,000 whales, dolphins and other marine mammals are unintentionally caught and killed in fishing gear worldwide. Under the new rule, foreign fishermen must meet the same marine mammal protection standards applied to U.S. fishermen or their fish will be banned from the lucrative American seafood market.
