"What could happen is you will have fewer scientists doing science," said Andrea Grottoli, head of the division of Water, Climate, and the Environment at Ohio State University. "There may be a whole lot less being done."
Grottoli and her team of doctoral students are examining the lethal effects of increasing acidic tropical oceans on coral reefs, a documented outcome of a warming planet.
"My two Ph.D. students were devastated because it affects their career options," Grottoli said. "Traditionally, the U.S. has been the best place to get science jobs."...
As the Earth Enters Its Third Mass Bleaching Event, Will Corals Survive?
Huffington Post online
2016-11-23
The world is experiencing its third mass coral bleaching event. Due to elevated temperatures at tropical locations over the whole planet, large populations of corals are starting to turn white. This is bad, as bleaching can lead to large-scale decreases in coral health and ultimately their death. Coral reefs provide shorelines with protection from storms, are foundational to tropical tourism and provide critical habitat to thousands of species. Large-scale coral death following mass bleaching leads to reef erosion, loss of shoreline protection, loss of tourism income and the livelihoods that depend on them, and loss of critical habitat.
Can corals keep up with ocean acidification?

"It also could explain why the calcification rates of many species of corals are not affected by ocean acidification," said co-author Andréa Grottoli at Ohio State University.

Fat makes coral fit to cope with climate change
The Ohio State University2015-11-17
Andréa Grottoli, professor in the School of Earth Sciences at Ohio State and principal investigator of the study, said that repeated bleaching will ultimately lead to less diversity in coral reefs, where all the different sizes and shapes of coral provide specialized habitats for fish and other creatures.
“Bleaching will significantly change the future of coral reefs, with heat-sensitive coral unable to recover,” Grottoli said. Interactions among coral hosts and their endosymbiontic algae, as well as predators and prey would then change in a domino effect...
For Corals Adapting to Climate Change, It’s Survival of the Fattest—and Most Flexible

“We found that some coral are able to acclimatize to annual bleaching, while others actually become more susceptible to it over time,” said Andréa Grottoli, professor in the School of Earth Sciences at Ohio State. “We concluded that annual coral bleaching could cause a decline in coral diversity, and an overall decline of coral reefs worldwide.”...
Coral Records Show Ocean Thermocline Rise With Global Warming

Williams and Andrea Grottoli, an associate professor of earth sciences at Ohio State and Williams’ former advisor, turned to a prolific form of soft coral, the Gorgonians, growing on a reef off the island nation of Palau.
“These corals ‘sway’ with the current underwater,” Grottoli explained, “like trees in the wind. Since they aren’t restricted to shallow and warmer surface waters like other tropical corals, they provide an opportunity to reconstruct a picture of subsurface ocean circulation in a region.”...
Tiny Polyps Need Two Kinds Of Carbon To Survive Coral Bleaching

If the rain forests were dying off at this rate, we would all be panicking, explained Andrea Grottoli, an assistant professor of geological sciences at Ohio State and lead author of the study.
The problem is that now, with the planet's climate warming, coral are living closer and closer to their thermal threshold, so it takes less of a warming event than it did before to cause a catastrophe.
Coral are symbiontic organisms that host one-celled algae within their bodies for mutual benefit. The coral polyp, a relative of jellyfish and anemones, provides a safe home within its cells for the algae while the algae convert sunlight into energy for the polyp...
