From one of the world’s most renowned cave divers, a firsthand account of exploring the earth’s final frontier: the hidden depths of our oceans and the sunken caves inside our planet 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. From one of the top cave divers working today—and one of the very few women in her field—Into the Planet blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earth’s remaining unknowns and the extremes of human capability. Jill Heinerth—the first person in history to dive deep into an Antarctic iceberg and leader of a team that discovered the ancient watery remains of Mayan civilizations—has descended farther into the inner depths of our planet than any other woman. She takes us into the harrowing split-second decisions that determine whether a diver makes it back to safety, the prejudices that prevent women from pursuing careers underwater, and her endeavor to recover a fallen friend’s body from the confines of a cave. But there’s beauty beyond the danger of diving, and while Heinerth swims beneath our feet in the lifeblood of our planet, she works with biologists discovering new species, physicists tracking climate change, and hydrogeologists examining our finite freshwater reserves. Written with hair-raising intensity, Into the Planet is the first book to deliver an intimate account of cave diving, transporting readers deep into inner space, where fear must be reconciled and a mission’s success balances between knowing one’s limits and pushing the envelope of human endurance.

The Ocean - Our Most Unexplored Frontier! Just as in outer space, there is a whole environment, or ecosystem, under the waters that cover 75% of our planet, with 70% of our planet being ocean waters.Beneath those waters there really is an entirely new world - a world full of beauty and mystery that few humans have the opportunity to experience. But the lucky few who do have the opportunity to experience this vast under water world are able to do so because they are scuba divers. Obviously, human beings cannot breathe underwater, so instead, they rely on a portable respiratory system that is self contained. In fact, that is what the word Scuba means: Self Contained Underwater Breathing Apparatus. This apparatus allows human beings to dive to depths that were once unthinkable, and to stay under the water for long periods of time, depending on how full the air tank is. Different mixtures of gasses are used in the air tank, depending on the length and depth of the planned dive. WHY KEEP A LOGBOOK?
