This module provides information on: (1) the origin of the oceans; (2) sources of minerals and salt found in the sea; and (3) the role and uses of salt in various cultures (stating, for example, that the expression "salt of the earth" describes a person who is considered one of the best). (JN)

The beach and sand dunes are the first line of defense protecting the land from the sea. The effectiveness of the beach is caused by its sloping surface which dissipates the energy of waves and by the flexibility of the slope which changes as the waves change. The process and rate of accretion and erosion are dependent on the size and frequency of…

Whether in carrier flight operations, resupply at sea, antisubmarine warfare, amphibious landings, sea search and rescue, or ship routing, sea conditions, at the place and time the operation is being conducted, become vitally important. The success or failure of any operation being conducted in an ocean environment is greatly dependent upon the…

Brief descriptions and eight activities related to zooplankton, sharks, dune ecology, ocean currents, and sea products comprise this manual. Among the activities are harvesting seafood, making Japanese fish prints, and tracing marine currents with drift bottles. (WB)

This guide, designed for students in grades 3-7, answers intriguing questions about phytoplankton, tiny drifters that have shaped our world. Invisible to the naked eye, phytoplankton are the source of our atmosphere, our climate, our ocean food chain, much of our oil supply, and more. They're also food for zooplankton. Photomicroscopy serves up…

This manual, developed for use in Alaskan secondary schools, is one of a continuing series designed to provide basic information about the marine environment and Alaskan marine resources. The first part of the manual presents information about tides, focusing on: the nature of tides; cause of tides; factors related to tidal movement; types of…

This booklet contains a programmed lesson on the properties of sea water. It is designed to allow students to progress through the subject matter at their own speed. Since it is written in linear format, it is suggested that students proceed through the program from "frame" to succeeding "frame." Instructions for the students and a list of lesson…

This series of experiments seeks to provide laboratory exercises which demonstrate concepts in Earth Science, particularly oceanology. Materials used in the experiments are easily obtainable. Examples of experiments include: (1) comparison of water hardness; (2) preparation of fresh water from sea water; (3) determination of water pressure; (4)…

This secondary school unit focuses upon international disagreements regarding rights to marine resources. Students study maps of the Atlantic Ocean to describe continental shelves, ocean basins, coastal features, and areas rich in natural resources. They then participate in a simulation to learn how conflicts arise over resources of the sea.…

This manual has been produced for use in a four-week training program developed by University of Rhode Island fisheries educators for the training of United States citizens in the duties and responsibilities of observers placed on foreign fishing vessels operating in the Fisheries Conservation Zone in the Atlantic Region. The program combines…

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,…

This booklet contains a programmed lesson on oceanic circulation. It is designed to allow students to progress through the subject at their own speed. Since it is written in linear format, it is suggested that students proceed through the program from "frame" to succeeding "frame." Instructions for students on how to use the booklet are included.…

Intended primarily for the secondary level, this manual presents 35 laboratory and field activities in marine science. Also included are chapters which cover field trip logistics, marine science centers, films, and reference materials. Typical amonq the lessons are "Charting Local Current Systems,""Salinity,""Living World Within a…

This collection of student activities for grades four through twelve presents action-oriented experiences with hardy aquatic organisms as the foundation for a laboratory-oriented science program. The format is characterized by pre-lab, post-lab, and student sections. Pre-lab topics include level, concepts, facts, suggested prerequisite skills,…

This guide is intended to improve the writing and composition skills of oceanography students but it may be applied to other written scientific compositions. Discussed is the documenting of laboratory and field investigations during the activity. A suggested format for the research report is presented with discussions of each section. A segment is…
