Big Environmental issues:

Here is a project that has come back to us for a second round.  Ken Calderia is a climate Scientist, and he studies the effect of atmospheric CO2 on coral reefs.

This link is to an NPR article (written and audio) about what he is doing on the Great Barrier Reef In Australia, and also about what we made for him that helps him test his theory.    The yellow inflatable you see in this picture is a light weight tank that floats in the water, and it is a place where Antacid is mixed to spread over Coral reefs.  Hear or read the story here at this link.

USGS Clear Plastic Chamber for Ocean Water Chemistry Studies
Nathan Smiley form the USGS in Florida commissioned us to build something we have never done before. To do this work we had to re think our process so we could weld unsupported vinyl film into a cataraft tube shape. The USGS be suspends this tube inflated with sea water under water for water quality analysis. We also built large clear tarps for the Sharq project. These studies will help find answers to why coral reefs are dieing world wide. This study is critical to our survival since 70% or more of our oxygen comes from healthy oceans. To learn more about the work that they do visit these web sites.
