Book excerpt: Scientists and engineers embarking on their first voyage for oceanographic or meteorological research are often unprepared for the experience. Going to sea involves learning a new language – that of the seaman. This is necessary for clear communications, for the safety and well-being of the members of the scientific party and the ship’s crew. The Oceanographer’s Companion is intended to familiarize a student with the basics of navigation, seamanship, marine engineering, communications, safety-of-life-at-sea, shiphandling, knots and splices, first aid, and so much more. The book will have a very practical feel with lots of examples.
