A new model of coral reef health

"...She found that there were only a few major factors that drove variations in the health of the coral reef community. Fish biomass was primarily driven by biophysical drivers such as water temperature. In contrast, the algal cover was driven mainly by anthropogenic factors, with significantly less macroalgae in places with more terrestrial and marine protected areas..."

Do's and Don'ts / Save Owl's Head

"...Shallow marine environments have been degraded by human intervention to disastrous extents. Along the Northeastern shores of North America, about ¾ of all eelgrass is gone – as a result of degraded water quality, caused by pollution that causes eutrophication (oversupply of nutrients, leading to a decline in species diversity and a rise in opportunistic single species), overfishing, massive sedimentation and disease. But while Nova Scotia’s shores, especially our Eastern shore, are still relatively undeveloped, warming oceans also pose a threat to these ecosystems..."

Sulfur enhances carbon storage in the Black Sea

"...The researchers posit that reactions with hydrogen sulfide play an important role in stabilizing carbon compounds. "This mechanism apparently contributes to the fact that there is more than twice as much organic carbon in the waters of the Black Sea as in oxygen-rich marine areas," says Niggemann. "This provides a negative feedback in the climate system that could counteract global warming over geological periods..."

Air and water quality at the Port measured around-the-clock

"...The information gathered at PRPA’s two air monitoring stations, at Westview and Fairview Terminals, helps establish baselines for air quality, through the measurement of nitrogen oxides, sulphur dioxide, and tropospheric ozone. Similarly, PRPA helps maintain the integrity of the marine environment through water testing in several ways. Water quality is tracked in real-time at two installations on Digby Island and at Atlin Terminal..."

Clearbot ups its marine-trash-removal game with help from Razer

"...Back in January, we covered an autonomous plastic trash collector called Clearbot that was designed to remove waste from areas such as harbors, lakes and canals. Now the startup behind the project has partnered with gaming titan Razer for an updated design. It is estimated that around 11 million tons of plastic waste enters the ocean each year, and we've been following cleanup efforts by the likes of The Ocean Cleanup, the Ocean Conservancy, and others for some time..."
