oceanography

Examines the world's major oceans and how they were formed. Also discusses the continual changes taking place on the ocean floor and along the coastlines and their implications for the future.

Discusses the unique creatures that live in the deepest parts of the ocean, the submersibles that let scientists explore the dark and dangerous waters, and some of the shipwrecks that have been found, with photographs.

Provides information on the history of deep sea exploration, from how explorers reach new depths to what they find there.

Color illustrations and text show five different ocean environments based on ocean depth and the animals that live in each.

" ... In Marine ecosystems, students will explore saltwater environments -- from shorelines to coral reefs -- and learn about the fish, plants, mammals, and insects that depend on each other for survival in this aquatic biome. Examine concepts such as salinity and currents, and find out about the three major life zones found in ocean waters. A fun, hands-on experiment allows students to discover how brine shrimp have adapted to changes in salt concentration, while a visit with a marine biologist on the Chesapeake Bay examines the fascinating life cycle of the blue crab.

Explores the science of oceanography, including ocean currents, the ocean's salt content, and what makes the ocean move. Features an interactive question-and-answer format and hands-on activities.

"From tsunamis and sea turtles to riptides and reefs, learn all about the creatures, science, and ecology of our oceans, which cover more of the planet than all the continents and are just as important! Travel through all parts of the ocean to learn how it affects our world, including storms and climate. Amazing facts, photos, illustrations, and diagrams are found throughout this book, along with conservation tips, weird-but-true facts, and a mini ocean atlas. Challenges to the health of our ocean and its creatures are also presented along with what people are doing to keep it pristine for generations to come.

Reveals the animal life that lives in the deepest oceans and examines the technology that allows scientists to conduct research in areas characterized by trenches, vents, and seeps.

Discusses dolphins and sharks, their ocean habitats, and general information about oceans and oceanography.
