Infographic: Inside Coral Bleaching by bioGraphic

bioGraphic has posted an excellent infographic called “Inside Coral Bleaching”. The graphic was rendered from a 3D model that consisted of over 20,000 images captured primarily by scientists from the 100 Islands Challenge Team. The photogrammmetry was created using Agisoft Photoscan, Blender and Cycles with animations of fish and the coral polyps expelling their zooxanthellae algae added in post.

The reef was surveyed in November and December by Japan’s Environment ministry. The bleaching is the worst in the recorded history of the reef and is due to rising sea temperatures.

A plan to save corals in a warming ocean

Two scientists are looking at ways to save the worlds coral reefs, but in a very controversial way, by speeding up evolution. The two scientists, Ruth Gates and Madeleine van Oppen of the Australian Institute of Marine Sciences, have decided to focus on the corals that do not eject their zooxanthellae during a bleaching event in an effort to make the reefs more resilient to rising sea temperatures.
