Manta Net operations continue to run smoothly as Okeanos Explorer remains underway towards San Francisco. Tows are conducted four times a day, and have consistently collected a variety of marine life along with bits of plastic. Some samples have contained a relatively high abundance of plastic, whereas other samples hosted a relatively low abundance (perhaps due to high winds and surface mixing). Since Okeanos’ apparent entrance to the “Garbage Patch” on October 21st, manta net tows have collected plastic every day.'s crew conducts routine training and maintenance. The last manta net tow of the cruise was conducted this evening. Today's manta net results suggest Okeanos Explorer has left the Pacific "Garbage Patch". The ship completed its last of 3 time changes today, bringing it up-to-speed with the West Coast. We expect to arrive in San Francisco tomorrow morning.
