Teams of scientists dive beneath the waves to study one of the planet’s most prolific and mysterious rites of reproduction: corals spawning – a spectacular event occurring once a year after the full moon. “While scientists have learned a lot since discovering the rite decades ago, much remains unknown, especially about the exact mix of environmental factors that trigger the synchronized […]

celebrate national oceans month

NOAA's #30daysofOcean

The month of June is dedicated to spreading awareness of Earth’s oceans and coastal ecosystems. About 71 percent of the Earth’s surface is ocean and while there is only one global ocean that is geographically divided into distinct named regions. NOAA is promoting awareness of all oceans on their site with #30daysofOcean…what do you know about our oceans?

A recent international study has found that rapidly rising seasonal sea temperatures are the likely trigger for the spectacular phenomena of mass spawning. 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 […]

bubbles may protect coral reefs

New research suggests that blowing tiny bubbles through seawater may help protect coral reefs from increasingly acidic oceans by stripping dioxide (CO2) from the coastal marine environments and transferring it to the atmosphere. The technique used by Stanford scientists could provide a relatively inexpensive solution to this threat facing coral reefs today. It is estimated that 30 to 60 percent […]
