Last week, billionaire investor and political newcomer Wilbur Ross was confirmed as Secretary of Commerce, the agency that houses NOAA. Secretary Ross made some positive comments about protecting peer-reviewed research at NOAA during his confirmation …
An evolutionary war that raged beneath the sea more than 100 million years ago created the octopus and squid, new research has shown. Cephalopods – the tentacled creatures that include octopuses, squid and cuttlefish – possess some extraordinary traits such as instantaneous colour changing, ink squirting, jet propulsion and polarised vision.
People have been exploring the Earth since ancient times—traversing deserts, climbing mountains, and trekking through forests. But there is one ecological realm that hasn’t yet been well explored: the oceans. To date, just 5 percent of Earth’s oceans have been seen by human eyes or by human-controlled robots.
The six ocean hot spots that teem with the biggest mix of species are also getting hit hardest by global warming and industrial fishing, a new study finds. An international team looked at more than 2,100 species of fish, seabirds, marine mammals and even tiny plankton to calculate Earth’s hot spots of marine biodiversity.
A new analysis of population trends among coastal sharks of the southeast U.S. shows that all but one of the seven species studied are increasing in abundance. The gains follow enactment of fishing regulations in the early 1990s after decades of declining shark numbers.
Last year’s devastating category-5 hurricane — Matthew — may be one of many past examples of a tropical storm fueled by massive rings of warm water that exist in the upper reaches of the Caribbean Sea.
Congress was in recess last week, so it was slightly quieter on Capitol Hill than in recent weeks. But it wasn’t quiet at COL, as we’ve been putting the finishing touches on our annual public …
Some ocean currents, like the Agulhas Current in the southwestern Indian Ocean, act like giant air conditioners, moderating Earth’s climate by shuttling heat from the equator toward the poles. The Agulhas is one of the largest and fastest currents in the world: Flowing southwest along the east coast of Africa, it stretches almost 1,500 kilometers and transports about 70 million cubic meters of water every second toward the South Pole at peak speeds upward of 7 kilometers per hour.
Oceans across the globe are slowly losing oxygen, which poses a major problem for every living marine animal and underscores the serious consequences of climate change, researchers say. A new Nature study published this week found that oxygen levels in worldwide oceans have dipped by more than 2% in the last half-century. While the change may seem small, scientists say even subtle shifts in gas levels can alter entire ecosystems.
Being a baleen feeder isn’t easy. When baleen whales — like the enormous blue whale — gulp up a mouthful of water to filter for food, a pouch of skin under their chins stretches to accommodate the load. This stretch should hurt, but new research finds that whale nerves are specially adapted to prevent these giant beasts from feeling pain.
