This afternoon, we tested out the V-wing, an instrument that we tow behind the ship. The V-wing is built so that it dives deeper into the water column as the ship moves faster. This means we can control the depth at which the V-wing takes measurements by moving the ship faster or slower, or by changing the length of the cable that attaches the V-wing to the ship. The V-wing has an ADCP to measure current velocities, and we can also add instruments to the tow chain such as a CTD.
