Dead Reefs Keep Calcifying but Only by Day

by J. Oetting 24 December 2019

A new measurement technique has revealed that turf algae communities colonizing dead reefs have a dual role, adding new mineral material to the reefs during the day and taking it away at night.

New Indian Ocean Program Builds on a Scientific Legacy

by R. R. Hood, M. J. McPhaden and E. Urban 30 September 201431 May 2015

From 1957 to 1965, 46 ships under 14 flags collected data for the International Indian Ocean Expedition. Now, 50 years later, scientists are planning a fresh effort to study the Indian Ocean.
