Gulf of Mexico -- 2010 November

In November, we flew by commercial airlines to the Gulf and brought with us two of our best volunteers from the Sea Shepherd Conservation Society.  Using the Sea Shepherd RV, boats and trucks donated by local Gulf citizens, and a very high-quality UV lamp (365-nm) suited for identifying the signature of crude oil and dispersant chemicals, we took over 50 unique samples of beach sand, coastal marsh sediment, water, and fresh-caught marine life (pogey, croaker, squid, shrimp, crab, and oyster).  Following very rigorous protocol for collecting, packaging, recording (Chain of Custody forms), and shipping, we sent these samples to very reputable laboratories on the East Coast and in Canada for analysis.  We'll share the results (some of which are ongoing) of these laboratory analyses here.
