Oceanography Learning Guide

This guide is no longer in print and is unavailable at this time.

You usually can’t see them, but things happen in and under the oceans every day that affect your life.  This non-technical guide to marine geography, earth crusts and plates, ocean chemistry, effects of weather, tides, currents, and wave formation will bring you hours of enjoyment.

USPS Guides are available to members and the public at various marine supply stores, and also directly from United States Power Squadrons Headquarters by calling 1-888-FOR-USPS between 8:30AM and 4:00PM ET Monday through Friday, or on-line via the United States Power Squadrons Ship's Store.  Visa, MasterCard, Discover, and American Express are accepted.  These guides are also available to USPS members at reduced rates through their Squadron Educational Officer.
