Two swimmers, close friends and archrivals, chase after the same Olympic gold medal. Archie Hayes is the best swimmer in the world. Talent and luck have brought him Olympic medals, fame, money and women. Doyle Wilson has reached the end of his career with dreams unfulfilled, but he has a final chance in the 400 freestyle, in which Archie owns the world record. Doyle bets that hard work will enable him to beat Archie just once. He burns all his bridges to focus on his lone goal. But Doyle can't be single-minded. Archie is not just his nemesis - they're best friends. Danger lurks around every corner for Archie, a celebrity athlete with a reckless streak. On a training trip to Hawaii, when Archie is mauled by a wave while bodysurfing, Doyle sees his duty - a purpose in life that transcends self-interest and even friendship. Archie's incomparable talent must be preserved and nurtured, and only Doyle can do it. Though Archie's demise would liquidate the main obstacle in Doyle's path to greatness, Doyle rescues him. Repeatedly. Doyle's odyssey to the Olympics teaches him about true friendship and love, the meaning of sacrifice and overcoming obstacles.

This handbook attempts to translate data on various parameters of man's capability in underwater and hyperbaric environments for those without a background in the life sciences. Accomplishing any multifaceted task requires team work, and effective team work depends on facile communication among all participants. To communicate properly, all parties must understand each other's problems and be able to speak a similar language. To this end we believe that this publication will go a long way in furthering the understanding and communication necessary for maximum achievement. The U. S. Navy has a fundamental interest in all types of activities connected with the ocean and is especially interested in the growing field of manned underwater and hyperbaric activities. Thus, the manuscript for this comprehensive book was developed under Office of Naval Research contract N00014-67-A-0214-0013 with The George Washington University. We acknowledge with appreciation the financial support and technical guidance for this undertaking by the Naval Medical Research and Develop ment Command of the Bureau of Medicine and Surgery as well as by the Engineering Psychology Program and the Physiology Program of the Office of Naval Research. JOSEPH P. POLLARD Director Biological and Medical Sciences Division Office of Naval Research vii Preface A need was felt for a book that would document the relationship of the human being to the underwater hyperbaric environment in such a way that the individual unfamiliar with the psychological or biomedical jargon could still understand and appreciate the information.

Ever played fetch with a four-eyed Grerk or made pancakes with a giant orange squurm? Nelly isn't scared of monsters. In fact she babysits for them. Every night, Nelly the monster sitter looks after a new friend, but its never easy... Nelly can't believe her luck when she finds out that the Water Greeps live in an underwater penthouse. The only problem is Water Greeps are mischievous monsters, and Nelly is going to have to get a bit wet!

While Callista Sunders recovers in a hospital room from an unexpected accident, hopelessness fills the crack in her heart and only love can repair the fissure. Love is something she never thought she would find outside of her Grandma Anne, her mother, and her twin brotheruntil she met Lord Triton. But now he is missing and Callista fears the worst. All she has is his sigil that she wears around her neck and the hope that one day they will be reunited. Callista never thought shed be spending her eighteenth birthday in the hospital, but when she receives Tritons journal as a gift, everything changes. While studying it with Grandma Anne, Callista finds a spell designed for time travel. Anne, along with her coven attempt to send Callista back in time to the island they know as Pitcairn. If it works and she survives, Callista will know Triton, but to him, she will be a complete stranger. In this continuing tale, a young woman must use her special abilities and a time travel spell to find Triton, a merman deity who needs her help, and she, his.

The subject of this volume is two-fold. First, it gathers typical polarization patterns occurring in nature. Second, it surveys the polarization-sensitive ani mals, the physiological mechanisms and biological functions of polarization sensitivity as weIl as the polarization-guided behaviour in animals. The monograph is prepared for biologists, physicists and meteorologists, espe cially for experts of atmospheric optics and animal vision, who wish to under stand and reveal the message hidden in polarization patterns of the optical environment not directly accessible to the human visual system, but measur able by polarimetry and perceived by many animals. Our volume is an attempt to build a bridge between these two physical and biological flelds. In Part I we introduce the reader to the elements of imaging polarimetry. This technique can be efflciently used, e. g. in atmospheric optics, remote sens ing and biology. In Part 11 we deal with typical polarization patterns of the natural optical environment. Sunrise/sunset, clear skies, cloudy skies, moonshine and total solar eclipses all mean quite different illumination conditions, wh ich also affect the spatial distribution and strength of celestial polarization. We pre sent the polarization patterns of the sky and its unpolarized (neutral) points under sunlit, moonlit, clear, cloudy and eclipsed conditions as a function of solar elevation. The polarization pattern of a rainbow is also shown. That part of the spectrum is derived in which perception of skylight polarization is optimal under partly cloudy skies.
