Benthic Foraminifera of the Gulf of Mexico: Distribution, Ecology, PaleoecologyIn 1981, Woods Hole researcher C. Wylie Poag published the book Ecological Atlas of the Benthic Foraminifera of the Gulf of Mexico. In this new volume, Poag has revised and updated the atlas, incorporating three decades of extensive data collections from the open Gulf and from an additional seventeen estuarine systems to cover species of benthic foraminifera from more than eight thousand sample stations. Benthic Foraminifera of the Gulf of Mexico features 68 plates of scanning electron photomicrographs, 64 color figures, and a large color foldout map, indicating species distribution of forams. This book is designed to aid students and teachers of geology, biology, oceanography, and ecology, as well as micropaleontologists in government and industry laboratories, and other researchers and consultants who have an interest in benthic ecology or paleoecology. |
