[Coral-List] New paper on internal waves

So that I don't have to purchase the article to read it, can you explain why
stratification is a good proxy for internal wave activity, and what do you
mean by "activity?" Do you mean energy, amplitude, or what?

Subject: [Coral-List] New paper on internal waves

Dear Coral-List,

There is growing recognition of the importance of internal waves on coral
reefs, with papers in the last few years showing that internal waves can
elevate nutrients and enhance coral heterotrophy, and more recently that
internal waves may reduce bleaching, on some coral reefs.

I want to draw your attention to our recent publication in Geophysical
Research Letters, "Climate modulates internal wave activity in the Northern
South China Sea". The take-home message of the paper is that internal wave
activity is projected to increase in this region under 21st century climate
change, with important implications for coral resilience to warming and
ocean acidification. Link to our paper here:

The South China Sea is home to possibly the world's largest internal waves,
which collide with Dongsha Atoll and influence the temperature and nutrient
environment for the corals living there. Our paper focuses on the
climatology of internal waves in this region, and their projected changes
over the next century. Given the mounting body of evidence that internal
waves not only buffer corals from thermal stress, but play key roles in
modulating the composition of source-water to reefs in some regions, a
changing internal wave climate potentially represents an important factor in
coral reef resiliency to climate change.
