Decoding Coral Reefs: Exploring Their Status, Risks and Ensuring Their Future

"...Overfishing is the most pervasive local threat to coral reefs. It can alter the ecological balance on the reef through removing herbivorous fish that control the macroalgae growing on coral. Sedimentation from land clearing also poses a major threat, as sediments within the water column can bury the corals and reduce the amount of sunlight that reaches the zooxanthellae, therefore limiting their access to nutrients from photosynthesis..."

Seaweed Is Putting Sea Turtles in a Hot Mess Hakai Magazine

"...Baby sea turtles don’t have an easy start to life. Breaking out of their eggs into a dark nest, they must dig themselves out of the sand, shuffle down to the water’s edge, and begin a dangerous odyssey through the ocean. From incubation to maturation, they face many threats, from ants, crabs, and suffocating seaweed to plastic and habitat loss..."

Space bacon, anyone? Canadian contenders tackle space food challenge

"...The rules are daunting. The winning system must help feed four astronauts on a three-year mission with no resupply, use a space about the size of a refrigerator, with strict weight and power limits, and "create a variety of palatable, nutritious, and safe foods that require little processing time. "..."

MIT's Oystamaran robot could boost the oyster-farming industry

"...Although the robot presently performs much of its work by real-time remote control, the students are working on making it fully autonomous. It will then use one forward-facing camera to initially identify and make its way over to each bag, after which it will use a downward-facing camera to align itself over the bag and perform the flip. It is hoped that once developed further – perhaps by an industry partner – the technology could help oyster farmers to increase their output, while also fostering interest in the field of aquaculture robotics..."

Special boosted coral is now reproducing on degraded areas of reef

"...If corals are going to survive on today's ecologically stressed reefs, they've gotta be tough. Scientists have therefore been developing a special "turbo-charged" coral, which has recently been found to be reproducing on the Great Barrier Reef. Corals reproduce by releasing eggs and sperm (collectively known as spawn) into the water..."

Ambitious Urban Sequoia skyscraper designed to clean the air around it

"..."This solution allows us to move beyond net zero to deliver carbon-absorbing buildings, increasing the amount of carbon removed from the atmosphere over time," says SOM. "After 60 years, the prototype would absorb up to 400 percent more carbon than it could have emitted during construction. The captured carbon can be put to use in various industrial applications, completing the carbon cycle and forming the basis of a new carbon-removal economy..."

Seaweed on Greater Victoria beaches part of largely uncharted ecosystem

"...In the ocean, seaweed is a forest-like haven for all kinds of marine life, but when it washes ashore it becomes a food source for very particular types of insects. In fact, Gibson said there are several families of flies he knows of that only feed on bull kelp and don’t exist in any other ecosystems..."

Blue-green algae bloom reported at Lower Thetis Lake in View Royal

"...Algae blooms can occur any time of year and across of variety of freshwater bodies, according to the CRD. They form when lake bed nutrients mix with surface water – a common event in shallow water bodies such as Beaver Lake, and more likely in winter for deeper lakes such as Elk Lake, following storm events or other instances of lake turnover..."
