It’s amazing that nobody has spotted it before. Superimposed on every ocean on the planet there is a striped pattern of currents. Yet what causes them is a mystery. Between 1992 and 2003, Peter Niiler of the Scripps Institution of Oceanography in San Diego, California, and colleagues collected data from more than 10,000 drifting ocean buoys, which they tracked with satellites. As expected, the buoys’ movements were influenced mainly by known global currents, which are driven by wind and by differences in the temperature and salinity of seawater. But when the team analysed the data, it emerged that something else had been subtly influencing the buoys’ paths. It turned out that there were alternating strips of water running eastward or westward, a bit like parallel moving pavements. Niiler recalls his reaction: “My God, we’ve never seen these before.”

The oceans just got a little safer for sharks. Fishermen must bring their shark catches to shore with fins still attached, the US fisheries service has decided. The new rule, put forward last week, aims to prevent fishermen from slicing fins off vulnerable species and discarding the rest at sea.

Four commonly found sunscreen ingredients can awaken dormant viruses in the symbiotic algae called zooxanthellae that live inside reef-building coral species. The chemicals cause the viruses to replicate until their algae hosts explode, spilling viruses into the surrounding seawater, where they can infect neighboring coral communities. Zooxanthellae provide coral with food energy through photosynthesis and contribute to the organisms’ vibrant color. Without them, the coral “bleaches” - turns white - and dies.

The annual mass spawning of corals on the Palau archipelago in the western Pacific has occurred right on cue. With Sunday night’s full moon, coral polyps let forth a huge swathe of sperm and egg, to seed the next generation. The event was short-lived - only about 30 minutes - but so vast in its scale that it turned the sea water pink. Scientists from Palau, Australia and the UK are studying the practicality of collecting coral larvae to help restore damaged reefs elsewhere.
