Celebrate the 50th anniversary of the dive to the bottom of the Marianas Trench with a commemorative copy of the next Marine Technology Society (MTS) Journal—Into the Trench: Celebrating the Golden Anniversary of Man's Deepest Dive. With remembrances by the Trieste's pilot, the master of the boat and other original participants, you'll explore the technologies that ruled the deep in those long-ago days. You'll also learn where future technologies are headed (including a paper about the latest visitor to the Challenger Deep, the hybrid ROV Nereus) and about the latest discoveries in the hadal sciences. Included in this issue are the work of two middle school science teachers who developed a new and innovative hands-on project to teach concepts of buoyancy based on bathyscaphes. Call the MTS home office at (410) 884-5330 to make sure a copy is available for your bookshelf.
