The Earth's oceans represent the only one of the ten biomes recognized by scientists that exists beyond dry land. It also is by far the largest and most diverse of the biomes that exist in our world. Covering the vast majority of the globe, the Earth's oceans contain vast chasms that dwarf the Grand Canyon. Undersea mountains spring up from the ocean's floor and achieve hidden heights comparable to the highest peaks that mountaineers scale. Buried in the ever dark depths, fish and other life forms exist that no human being has yet seen. All in all, as Trevor Day vividly chronicles in this illustrated title in the "Biomes of the Earth" series, the oceans represent the least explored region of the world. In this book readers will encounter a well-researched and lucidly written account of keynote features of the ocean biome. Particular attention is paid to changing ecosystems, environmental threats to the world's oceans, various life forms, and the balance that must be struck between human exploitation and the welfare of the seas. This is a carefully crafted work, one that will provide valuable guidance to youngsters who peruse it.
Children's Literature - Greg M. Romaneck
Each book in this ten-volume series considers the range, geography, geology, biodiversity, history, and uses of the biome and its possible future. There is no comprehensive index for the set, which limits the connection of various topics across the entire series. The information provided is quite extensive and inclusive and is enhanced with well-chosen color photographs, maps, and charts. Three authors are individually responsible for writing different books while conforming to the series guidelines. This series is designed to encourage interest in and concern for the natural world that sustains all. Oceans looks at the salty seas that cover two-thirds of the Earth's surface and considers the geography and geology of oceans. The author also explains their chemistry and physics, atmospheric influences that affect oceans and ocean currents, ecology, biology, the history of oceanographic exploration, and the effects on today's oceans of human exploitation and carelessness. The book is, in fact, a readable and quite comprehensive introduction to the subject of marine studies and oceanography. Consider just a few of the topics touched on: food chains and webs, salinity, El Ni±o, phytoplankton, plate tectonics, the Coriolis effect, Katrina, and sea lions. It is disappointing to see, however, under a section on climate change, "The big question is, is it happening?" Because the author elsewhere discusses present and potential effects of global warming-coral bleaching, changing sea levels, greenhouse gases-it is doubly surprising to find this phrase in a current high school text. Also the last cited reference used to answer that provocative question is dated 2001, hardly acceptable in a fieldin which research is ongoing and intense. Aside from this caveat, the book has a lot to offer biology and ecology students, a number of whom dream of being marine biologists. In general though, this excellent and detailed overview of the topic will appeal especially to more advanced students. Other books in the series discuss agricultural and urban areas, deserts, grasslands, lakes and rivers, Taiga, temperate forests, tropical forests, and tundra.
Gr 9 Up -Informative, up-to-date and wide-ranging, these detailed overviews cover all aspects of their terrains, with chapters focusing on geography (providing overviews of individual hot and cold deserts, and oceans), atmosphere, geology, biology, history, exploration, and economic resources. These revisions (Copyright 2008 Reed Business Information.
Deserts , 2000; Oceans , 1999) add recent ecological discoveries and coverage of phenomena such as the December 2004 tsunami (even, to a lesser extent, in Deserts ) and global warming. Though inclusion of these topics is now standard, these books warrant purchasing as they go further. For example, Oceans explores little-known aspects of the tsunami such as its underwater effects, and, after providing an unusually specific and frightening list of the threats from climate change, outlines an equally pointed to-do list to combat the problem. Generally, the books' plain language neatly explains both complex phenomena (the Coriolis effect) and easier concepts (the Atlantic Ocean is expanding at the same rate as fingernail growth), but some of the scientific explanations in Deserts are challenging. Both books' color maps and diagrams are helpful and plentiful, but the few color photographs (though there are more in Oceans than in the previous edition) are of average quality at best. Pair Oceans with the Smithsonian Institution and National Oceanic and Atmospheric Administration's Hidden Depths (Collins, 2007), which has stunning photographs and more on coastal habitats; Deserts will complement basic earth science textbooks, which will have alternative explanations of the related scientific concepts, but lack the detailon deserts found here.- Henrietta Thornton-Verma , School Library Journal
