extreme coral close-ups now possible

Two researchers from the University of California San Diego have developed an underwater microscope called the Benthic Underwater Microscope, or BUM, that allows divers to zoom in on wild corals and capture unprecedented features and behaviors. This new microscope is comprised of a lens, camera, and six bright LEDs that act as a flash contained within cylinder and controlled by an underwater computer. One behavior documented […]

This month-to-month increase in sea surface temperature can now help them to predict when mass spawning will occur. Mass coral spawning happens when dozens of coral species release eggs and sperm into the sea, on a few nights each […]
