What can sharks teach us about our immune system? What can horseshoe crabs show us about eyesight? This book explores the links among physical oceanography, public health, epidemiology, marine biology, and medicine in understanding what the ocean has to offer. It examines a wide range of ocean phenomena, ranging from tsunamis to estuaries to red tides to medicines and nutritional products that come from the ocean. The book recommends ways we can implement new technologies to monitor the physics, chemistry, and biology of the ocean so that we will recognize change as it happens.
