I obviously fluked (blame it on a Monday Morning) by writing “May 22-14,
2015” when I should have had “May 22-24, 2016” below:
Thanks, Carole,
I want to encourage everyone’s participation in our Mollusks in Peril forum,
on May 22-24, 2016, where all these relevant issues will be discussed by
researchers who have been devoting the last decade or more to the subject.
For more details, Check the event’s web site at www.mollusksinperil.org .
Have a great and productive Monday!

Dear Dave,
The Bailey-Mathews Shell Museum is having a 3 day symposium devoted to that
subject in May of 2016. It is a long way from Hawaii, but perhaps Jose can
give you better insight. I know ocean acidification is deadly to our little
pteropods, food for millions of sea creatures. Carole Marshall

Conch-L Community,
The article left me wanting more. So, what exactly is the pH trend in
this area? The article talks a lot about acidification without actually
mentioning any pH values. What studies have been done on the effects of
ocean acidification resulting from “natural” causes, like volcanic
eruptions, which, I imagine, can produce much more drastic reduction in pH
in a localized area than slow infusion of dilute CO2 concentrations from the
atmosphere. Also, it’s hard to imagine that anthropogenic CO2 has already
overwhelmed the buffering effects of all of the calcium carbonate that has
been produced over the course of billions of years. Maybe it has, but it is
very hard to imagine. We haven’t run out of oil yet and it will be a long
time before we will. How can a resource like calcium carbonate, which has
as its source many of the same life forms that eventually decomposed to form
oil deposits, be exhausted in its ability to counter a weak acid, like
carbonic acid? Also, what have temperatures been like in the area in
question , and has anyone looked at its contribution to the problems
encountered by the scallops. Calcium carbonate has a very unusual property
in that it becomes more soluble with drops in temperature. Are the
temperatures in the area dropping, resulting in poorer shell formation in
the scallop population? Science should always involve looking at things
from multiple angles. The whole ocean acidification topic should be treated
the same.
Aloha,
Dave
