Brownsville Veterans Memorial High School science teacher, Edward Walk, is one of only two educators selected to participate in a week long offshore expedition with the Gulf of Mexico Foundation in October.  The expedition will depart from Freeport, Texas aboard the M/V Fling, a 100-foot live vessel.  The focus will be on natural and artificial reefs and their overall contribution to the ecology.  Mr. Walk will network with scientists, educators, natural resource managers and oil/gas industry representatives and bring his experiences back to share with his students.
