Hardhats at Work

Engineering assistant Matthew Adams prepares “hardhat” floats for use in an upcoming project in the Lofoten Basin between Iceland and Norway in the far northern Atlantic. WHOI physical oceanographer Fiamma Straneo plans to study circulation and heat loss to the atmosphere in the basin by means of drifting RAFOS floats and an anchored profiling mooring. Each hardhat contains a hollow glass ball to provide flotation. Clusters of the floats will be attached to the mooring line to help support it while deployed and to help recover the instruments if the line becomes damaged.
