Coral
reefs represent one of earths most diverse ecosystems,
yet it is this very ecosystem that is in the most peril. Over
30 percent of the species in coral reefs are being threatened
in 2008. One of the key threats is climate-induced
coral bleaching and subsequent coral disease and mortality.
This bleaching is often caused by higher surface ocean
temperatures during the peak summer months. The
number of degree-days above normal has a large effect
on the chance of bleaching. Lowering the ambient
water temperature by as little as 1 degree for the peak
days is enough to reduce the number of degree-days substantially
and improve the probability of coral survival each
season.
Wave
driven ocean pumps can be deployed in a linear array
upstream from the target area to upwell cooler water
into the mixed layer and reduce peak temperatures of
surface waters. This cooler water advects onto the
reef, protecting the reef from the highest temperatures
that cause coral bleaching and subsequent mortality. By
deploying these pumps during the peak season each year,
it is possible to locally manage this effect of climate
change on high-value reefs, thereby preserving these
reefs during the coming decades. Making these critical
tools available to coral reef management authorities
may determine the survival of these coral reef ecosystems
in the years and decades to come, critical decades
during which the reefs will be most at risk until mankind's
greenhouse gas emissions come under control. Once
these benefits have been demonstrated through rigorous
field testing procedures, we can scale these coral
reef protection systems to cover extended reef areas
spanning hundreds of kilometers, thereby protecting
our reef ecosystems for decades to come and preserving
these jewels of the earth for future generations.
