Study Reveals Corals’ Influence On Reef Microbes

As they grow, corals are bathed in a sea of marine microbes, such as bacteria, algae, and viruses. While these extremely abundant and tiny microorganisms influence coral communities in a variety of ways, a new study by researchers at WHOI, BIOS and UCSB reveals that corals also have an impact on the microbes in waters surrounding them.

Ocean circulation implicated in past abrupt climate changes

There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges -- at times almost stopping.

New study links global ocean processes with local coral reef chemistry

Five years of data collected on reefs and offshore in Bermuda shows that coral reef chemistry – and perhaps the future success of corals – is tied not only to the human carbon emissions causing systematic ocean acidification, but also to seasonal and decadal cycles in the open waters of the Atlantic, and the balance of biochemical processes in the coral reef community.

Monster hurricanes reached U.S. during prehistoric periods of ocean warming

New research on coastal sediments, funded in part by BIOS’s Risk Prediction Initiative, shows that prehistoric hurricanes along the northern East Coast of the United States were likely more frequent and intense than those that have hit within recorded history.
