Howe Sound

With nearly 16,000 miles of rugged coastline and more than 40,000 islands and islets, British Columbia’s Howe Sound features fantastic marine life and spectacular coldwater scuba adventures. Stretching 27 miles from its narrow head under lofty mountain peaks at Squamish to its wide-mouth opening into the Strait of Georgia just northwest of Vancouver, Howe Sound is North America’s southernmost fjord. This sea-to-sky corridor crafted by glaciers and perfected by time seems tailor-made for subsea exploration — reef and wreck, rec and tech.

Diving in a Time Capsule

Thunder Bay National Marine Sanctuary in Lake Huron off the northeastern coast of Michigan has nearly 100 known shipwrecks, and others are still being discovered. The oldest shipwreck there sank in 1849, but many wrecks are from the mid- and late 1800s to the early 1900s. The location, history and variety of ships — from wooden schooners to freighters — make Thunder Bay special. The wrecks are at various depths, ranging from the snorkel zone to recreational and technical diving levels.

Florida Keys History Underwater

Beneath the ocean waves, our underwater history provides evidence of events and people that have contributed to our maritime landscape. Research on submerged sites is an ever-evolving frontier where discoveries continue to happen in places previously unknown to maritime historians. Diving in the Florida Keys National Marine Sanctuary (FKNMS) is an exceptional experience that offers […]

Blue Heron Bridge

THE RELENTLESS AND POWERFUL NORTHWARD FLOW of the Gulf Stream’s clear, tropical waters provides Southeast Florida with beautiful and unique diving opportunities. Passing off the coast of Palm Beach County, the warmer, constantly flowing water nourishes and replenishes reefs and corals that support and attract an incredible diversity of marine life. The reefs offshore are […]

San Diego

WHEN I MOVED TO SAN DIEGO, CALIFORNIA, from New England in January 2007, I knew next to nothing about the area. As I made my way across the country, I considered my future — one that was hazy, although it seemed likely to involve fish tacos and a diminished need to say that I “loved the seasons.” I had an easier time envisioning the local diving: towering kelp forests and sharks everywhere.

Connecticut: From the Shoreline

BETWEEN NEW YORK AND BOSTON LIES HARTFORD, the heartbeat of Connecticut. Visitors there can tour the Mark Twain House, Harriet Beecher Stowe Center, and the Wadsworth Atheneum Museum of Art. Beyond the city, trees and hills make way for fresh and coastal waters teeming with macro life.

Florida Panhandle: Down the Emerald Coast

Following the white sand beaches and emerald waters along the Florida Panhandle leads to a diverse set of wrecks and artifacts ranging from oversized sculptures to the largest purpose-sunk wreck in the U.S. This area of Florida is known as the Emerald Coast, and the visibility in this part of the Gulf of Mexico is superior to that along the Louisiana and Texas coastlines.

Ripoff Reef

When I dive in an unfamiliar area, I tell the dive operator I want to start at their best spot — the site with everything. If I get bored with that, maybe I’ll try other sites. If you came to my home turf on the Kona Coast of Hawaiʻi Island and asked me for the site that has everything, I would send you to Ripoff Reef.
