Unprecedented high-resolution data from undersea canyons off Vancouver Island’s west coast is bringing new understanding of the importance of these canyons as rapid-transit corridors for carrying carbon from the ocean surface to the deep sea.

An international study co-led by Ocean Networks Canada (ONC) staff scientist and University of Victoria biologist Fabio De Leo uses synchronized real-time data from “Wally” the deep-sea crawler and NASA’s MODIS satellite for the first time to measure carbon transport from the sea surface to the deep ocean by wintertime ocean circulation, canyon rim eddies and downwelling – the sinking of dense, cold water beneath lighter, warmer water.

With Halloween upon us, it’s worth remembering that living things take part in similar costume parties all year long, adopting weird and wonderful forms.

Though rather than a haul of candy, organisms might earn the chance to live, prosper and mate. It’s all part of evolution, the principle where the fittest individuals pass their genes onto the next generation.

After harvesting a corn or soybean crop, farmers may plant a cover crop for a variety of reasons—to reduce soil erosion and nutrient runoff, increase organic matter in the soil, and improve water quality. Now there’s another reason. University of Illinois research shows that migratory birds prefer to rest and refuel in fields with cover crops.

“The global rate of ocean warming has many consequences for life on this planet. Now we are learning that the Red Sea is warming even faster than the global average,” says KAUST PhD student of marine science, Veronica Chaidez.

Researchers have gained new insight into the formation of a group of compounds found in almost all organisms, which are reportedly shown to be a powerful antioxidant that protects cells from damage by free radicals. They found that these compounds were also essential in supporting the mitochondrial energy metabolism, which is known as sulfur respiration, and identified it for the first time in humans and other mammals.

In 1995, Adrian Piers, a veteran aquaculture consultant, imported a batch of Australian red claw crayfish to the tiny southern African monarchy of Swaziland. He began raising the attractive blue-green crustaceans — the males of which have red stripes on their claws and can weigh a little more than a pound — in ponds rented from a sugar estate, and soon found a market for them among French-style chefs in neighboring South Africa.

Recently, scientists from Florida Keys National Marine Sanctuary joined other partners from NOAA and outside organizations to conduct a rapid assessment of the Florida Coral Reef Tract, including areas in the sanctuary, following Hurricane Irma. Preliminary reports from the team found extensive shifting of sand and heavy sediment accumulation, which can smother and prevent corals from getting enough sunlight, as well as some structural damage to individual corals and the reef itself.

This effort is the first step in a longer recovery process and helps NOAA begin assessing damage and start preparing and prioritizing future restoration activities. The rapid assessment took place October 9-19.

National parks and nature reserves in South America, Africa and Asia, created to protect wildlife, heritage sites and the territory of indigenous people, are reducing carbon emissions from tropical deforestation by a third, and so are slowing the rate of global warming, a new study shows.

They account for just three per cent of the Earth’s surface but play a major role in offsetting carbon dioxide emissions – and now a team of scientists led by the universities of Southampton and Utrecht has discovered that the plants that make up peat bogs adapt exceptionally well to climate change.

Researchers at NOAA’s Alaska Fisheries Science Center are reporting a never-before-seen phenomenon in Alaska waters—an influx of strange organisms that resemble flattened, translucent sea pickles.

It may sound like déjà vu. A similar story made headlines along the West Coast last summer, but this is a new situation for Alaska.
