Marine giants make migrations across the ocean to give birth where predators are scarce, congregating annually along the same stretches of coastline. A study suggests that 200 million years before whales evolved, school bus-sized marine reptiles called ichthyosaurs may have made similar migrations.
Chemical fingerprints could land the biggest catch: seafood fraudsters
New technology developed by South Australian scientists is tracking the origins of seafood in a bid to combat fraudulent labelling and improve sustainability. Chemical fingerprints found in the bones and shells of marine life is key to knowing which ocean they come from.
Data from elephant seals reveal new features of marine heatwave ‘the Blob’
The North Pacific Blob, was the largest and longest-lasting marine heatwave on record. A new study using data collected by elephant seals reveals that in addition to the well documented surface warming, deeper warm-water anomalies associated with the Blob were much more extensive than previously reported.
High CO2 to slow tropical fish move to cooler waters
Under increasing global warming, tropical fish are escaping warmer seas by extending their habitat ranges towards more temperate waters. But a new study shows that the ocean acidification predicted under continuing high CO2 emissions may make cooler, temperate waters less welcoming.
Nuclear War Could Trigger Big El Niño and Decrease Seafood
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy – at least in the equatorial Pacific.
Fish sex organs boosted under high-CO2
Research from the University of Adelaide has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future.
Researchers Identify Which West Coast Regions Hold Greatest Wave Energy Potential
Washington and Oregon coastlines hold most promising areas to pull power from West Coast waves, according to a recent study on wave energy.
Marine food webs under increasing stress
Scientists at the University of Adelaide have found growing evidence that marine ecosystems will not cope well with rising sea temperatures caused by climate change.
RIGS TO REEFS
Oil platforms along the coast of California are being taken offline. Research conducted by CSU faculty and students brings to light the value of these artificial reefs.
Climate Change Could Threaten Sea Snails in Mid-Atlantic Waters
Climate change could threaten the survival and development of common whelk – a type of sea snail – in the mid-Atlantic region, according to a study led by scientists at Rutgers University–New Brunswick. The common, or waved, whelk (Buccinum undatum) is an important commercial species that has been harvested for decades in Europe and Canada for bait and human consumption. Its habitat within the mid-Atlantic region is one of the Earth’s fastest warming marine areas and annual fluctuations in the bottom temperature are among the most extreme on the planet due to unique oceanographic conditions.
