On Monday, 26 August 2019, the former airliner slipped slowly below the surface, just south of Aqaba's main port, to become the latest addition to the already substantial number of artificial reefs along Jordan's stretch of Red Sea coastline.

Aqaba sinks airplane for new artificial reef

The TriStar plane is a commercial airliner that has been out of service and parked at King Hussein International Airport for several years. The Aqaba Special Economic Zone Authority (ASEZA) recently purchased the plane with the intention of sinking it, and it was transferred to the main port to prepare it for is final role. The TriStar is the second aircraft to become an artificial reef off Jordan's coastline. In November 2017, a Hercules C130 was scuttled a bit farther down the coast.

What do white sharks make of divers in cages?

In a study, which monitored the surface behaviour of white sharks during cage-diving activities around Guadalupe Island in Mexico, researchers observed a variety of behaviours as well as the role of an individual shark’s length and maturity on whether or not it caught the bait offered during these encounters. The relative size of sharks also played an important part in social interactions between individuals, with smaller sharks giving way to larger ones, even if the smaller shark arrived first on the scene.

Split spawning can give coral reefs a second chance

When investigating whether corals that split their spawning over multiple months are more successful at spreading their offspring across different reefs, researchers discovered that split spawning can indeed improve the coral reef's resilience.

The findings of the study was published in the Nature Communications journal recently.

Standing on the swim step, trying to time my entry with a gap in the dozen or more lemon sharks circling directly below me was a bit daunting the first go around. Of course, the sharks knew this routine well and skillfully avoided my clumsy splash into the water. The reward waiting beneath the surface was an assemblage of sharks that cannot be collectively encountered anywhere else in the world.

Not Just a FAD: Saving the Reefs in the Seychelles Islands

Drifting fish aggregating devices (dFADs) are threatening endangered marine species and coral reefs in the Indian Ocean. Marine conservationist Lucy Martin worked with the Island Conservation Society (ICS), a non-governmental organization in the Seychelles, on a large survey in 2015 to find out how big an issue FADs actually were.
