Prof Kerry Sieh in the field with students.

NTU honours former EOS director Kerry Sieh with Emeritus Professorship

Our warmest congratulations to Professor Kerry Sieh, who has been awarded Professor Emeritus status! In a Professor Installation Ceremony that took place before the NTU President’s State of the University Address on 15 September, four retired NTU Professors, of which two are from the CoS, were conferred this honour. Professor Kerry Sieh retired after ten years as director of the Earth Observatory of Singapore (EOS) in January this year. Read more

Lights out for muddy water coral reefs as global sea level rises?

Lights out for muddy water coral reefs as global sea level rises?

Although the impacts of climate-related coral bleaching are well documented, knowledge of how sea level rise will influence reefs is limited. Global sea level rise (SLR) will present a major threat to turbid coral reefs, located in shallow coastal waters, by increasing the depth of water covering them, and reducing the amount of sunlight available on the seafloor. This will change the amount of habitat available for certain corals to grow, shows a new study led by ASE Presidential Postdoctoral Fellow and AXA Research Fellow Dr Kyle Morgan published last week in Proceedings of the Royal Society B.

Accelerating sea level rise could drown mangroves 30 years from now unless carbon emissions are cut

Accelerating sea level rise could drown mangroves 30 years from now unless carbon emissions are cut

A recent publication in Science, co-authored by ASE chair/EOS PI Prof Benjamin Horton, shows that  vast areas of mangroves are under threat from sea level rise, which may cause the mangroves to drown by 2050 unless we curb climate change by cutting carbon emissions. The study surveyed 78 sites in the tropics and subtropics around the globe, using paleorecords of mangrove growth and sea level rise to predict the future of these ecologically and economically important ecosystems.

Volcanic crystals reveal time scale of volcanic plumbing system processes

Volcanic crystals reveal time scale of volcanic plumbing system processes

Time scales of volcanic processes leading up to a volcanic eruption is a key part of the puzzle to predict volcanic eruptions, and this is the special interest of ASE Assoc Prof and EOS Interim Director Fidel Costa. In a recent article in Nature Reviews Earth and Environment, he outlines the technique of diffusion chronometry, where volcanic crystals are used as time capsules that, for those who know how to read them, can reveal the time scale of underground magmatic processes of a volcano.
