CONTENTS Winter 2018 ON THE COVER: To illustrate ocean optimism, we asked photographer David Doubilet to submit an image that shows what is right with the coral reef and what is crucial to protect. He chose this over/under image from Kimbe Bay, Papua New Guinea, because of the pristine corals and because it symbolizes mankind’s deep connection to the sea. Doubilet took the photo using a Nikon D3 camera, Nikkor 14-24mm f/2.8G ED lens at 14mm, dual Sea & Sea YS-250 strobes at full power with Ultralight arms, Seacam housing with Superdome and S10 viewfinder, with an exposure of 1/200 sec @ f/22 and ISO 400. FEATURES 68 REMOTE AND REWARDING AUSTRALIA’S FAR NORTHERN GREAT BARRIER REEF Text and photos by Stephen Frink Reports of the Great Barrier Reef’s death were greatly exaggerated. With charismatic fish and turtles, pristine branching corals and spawning invertebrates, the reefs of the far northern GBR are resilient and impressive. 76 DIVING ON SUNSHINE SUNSHINE COAST, BRITISH COLUMBIA, CANADA Text and photos by Brandon Cole British Columbia’s Sunshine Coast offers invertebrate-decorated walls, hulking shipwrecks, underwater thrill rides in tidal currents and some of the world’s best temperatewater diving. 82 OCEAN OPTIMISM By Nancy Knowlton, Ph.D. Amid reports of coral bleaching and plastic pollution, conservation successes are often overlooked. Nancy Knowlton, Ph.D., offers reasons to celebrate the marine environment and have hope for its future. 86 DIVING WITH DIABETES GUIDELINES AND THE LATEST RESEARCH By Cristian Pellegrini Although diving was once considered too risky for people with diabetes, research demonstrates that diabetics can dive safely with appropriate precautions.
