Book Description
Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.

Book Description
Oceans have had a mysterious allure for centuries, inspiring fears, myths, and poetic imaginations. By the early twentieth century, however, scientists began to see oceans as physical phenomena that could be understood through mathematical geophysics. The Fluid Envelope of Our Planet explores the scientific developments from the early middle ages to the twentieth century that illuminated the once murky depths of oceanography. Tracing the transition from descriptive to mathematical analyses of the oceans, Eric Mills examines sailors' and explorers' observations of the oceans, the influence of Scandinavian techniques on German-speaking geographers, and the eventual development of shared quantitative practices and ideas. A detailed and beautifully written account of the history of oceanography, The Fluid Envelope of Our Planet is also an engaging account of the emergence of a scientific discipline.
