The renowned cave diver takes readers on “a thrill ride into unfamiliar worlds”—exploring the hidden depths of our oceans and sunken caves (Publishers Weekly). More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. In this thrilling firsthand account, Jill Heinerth blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earth’s final frontier—and the extremes of human capability. One of the world’s foremost cave divers, Heinerth’s achievements include leading a team that discovered the ancient watery remains of Mayan civilizations and becoming the first person in history to dive deep into an Antarctic iceberg. In Into the Planet, she vividly recounts everything from discovering new species and examining our finite freshwater reserves to the prejudices women face when pursuing careers underwater.

"The project whose research led to the publication of 'Cave Life of Oklahoma and Arkansas' began in the 1970s as a study of Ozark cavefish and expanded to encompass two states and involve a number of research topics and collaborators. The authors and their team donned snorkeling gear, cave suits, and climbing harnesses and descended into caves in Oklahoma and Arkansas to study, inventory, and photograph this hidden world. The result is a comprehensive checklist of the region's cave fauna, complete with descriptions of these rare animals' distribution and ecological niches. The cast of characters ranges from familiar and charismatic species, such as cave crayfish and gray bats, to rare and bizarre fauna, such as blind salamanders and cave dung beetles. More than 175 full-color illustrations include stunning, never-before-seen photographs (from the cameras of Dave Bunnel, Tim Ernst, and Danté B. Fenolio, among others) of cave animals--even some newly discovered species. The authors also address conservation of subterranean biodiversity, discussing not only threats to cave life such as invasive species, resource extraction, and habitat loss, but also current methods of preservation and protection, including legislation, land acquisition, people management, and cave gates. The book's appendices provide a comprehensive cave bibliography and checklists of subterranean animals for each cave."--Provided by publisher.

The earth's subsurface contains abundant and active microbial biomass, living in water, occupying pore space, and colonizing mineral and rock surfaces. Caves are one type of subsurface habitat, being natural, solutionally- or collapse-enlarged openings in rock. Within the past 30 years, there has been an increase in the number of microbiology studies from cave environments to understand cave ecology, cave geology, and even the origins of life. By emphasizing the microbial life of caves, and the ecological processes and geological consequences attributed to microbes, this book provides the first authoritative and comprehensive account of the microbial life of caves for students, professionals, and general readers.

"My Cave Life in Vicksburg" is a first-hand account of the deprivations suffered by the civilian population during the Union army siege of the city of Vicksburg.
