Presented are various activities and projects intended to help Boy Scouts earn a merit badge in oceanography. Each project and/or activity is related to a requirement (objective) found in a list at the beginning of the booklet. Topic areas and/or related activities and projects include: (1) nature of oceanography (naming oceanography branches, describing ways man is dependent on oceans); (2) effect of oceans on weather and climate; (3) ocean waves; (4) drawing cross-section of underwater topography; (5) chemistry of the seas (listing and describing main salts, gases, and foods found in sea water, and explaining the importance of Dittmar's principle); (6) marine biology, focusing on phytoplankton, zooplankton, nekton, and benthos; (7) plankton collection (making plankton net, making models of volcanic island, making models showing inshore sediment movement, measuring water temperature, and making a wave generator); and (8) oceanographic record-keeping and reporting. Instructions and materials needed for projects and activities are provided when appropriate. Lists of books, hydrographic office publications on oceanography, and glossary of oceanographic terms are included. Activities and projects can be completed whether or not individuals live in coastal areas. (JN)
