Ghosts of the Pacific

Summary: "The fourth volume in the series, begins with Alfred and his crew of Seaweed the seagull and Hollie the dog undertaking a harrowing journey through the icy gauntlet of the Northwest Passage on the way to the South Pacific. Alfred wants to see those dark places of the earth where horrendous events have taken place. He sets his sights on exotic Micronesia -- a beautiful place, but home to the nuclear testing of Bikini Lagoon; the Suicide Cliffs of Saipan; the airfields of Tinian, where the Enola Gay lifted off with the atomic bomb; and the Marshall Islands, which may conceal secrets to the mystery of Amelia Earhart's final days. Yet even with these past tragedies in mind, Alfred discovers that the world is facing an even greater threat today. As they sail into the hot, hazy world of the Pacific, they encounter the ruthless killing practices of shrimp trawlers and an island of plastic the size of Texas. Along the way, Alfred, Hollie and Seaweed befriend the crew of an environmental protection ship, who help to inspire him to take on a new goal: to protect the oceans of the world." --From publisher.
