More information about the federal government's Rigs
to Reefs program is at www.bsee.gov/Exploration-and-Production/Decomissioning/Rigs-to-Reefs, with links to
state-specific programs in Texas, Alabama, Mississippi
and Louisiana (the link to California's program is currently
broken).
Other than contacting your state legislature, there are not
many ways for divers to lend verbal or financial support for
Rigs to Reefs. But the not-for-profit Coastal Conservation
Association, with chapters in 17 coastal states, campaigns
and seeks funding for the building of artificial reefs, including
rig-to-reef projects. ( www.joincca.org/about )
Two researchers at the Scripps Institution of
Oceanography started the Rigs-to-Reefs project, diving oil
platforms off the California coast and in the Gulf of Mexico
to document (with GoPro Hero 3+ cameras) the ecosystems
that grow on and around the platforms, and using the
information they gather to help the public make informed
and responsible decisions about oil rigs in the ocean. You
can see their photos and support their project at www.rig2reefexploration.org
