It’s All in the Name

In 1995, when we first explored wunderpus territory, which overlies much of the Coral Triangle, the then-undescribed octopus’ fame had spread far and wide. The newly sensational creatures attained much of their acclaim for dancing like dandies across sandy seafloors on eight unimaginably limber arms — an eye-popping feat of acrobatic dexterity well worth traveling halfway around the world to see.

Air and a Spare

No matter which alternate air source you choose, learn to calculate your air consumption and regularly practice emergency procedures. There are many ways to configure each type of redundant breathing-gas supply, but make sure your setup matches your training, gear arrangement and dive objectives. If a naysayer thinks your equipment choice is unnecessary, let them know that the difference between a fatal accident and an embarrassing incident could come down to a breath or two. Any redundancy is better than none.

The Blue Desert Conundrum

Where we encounter marine megafauna, we see only a tiny slice of their habitats and lives, which rarely includes feeding. These animals may travel thousands of feet vertically or migrate a few thousand miles horizontally to meet their nutritional needs. Some of them — sperm whales, for example — must do both: descend to depths of up to a mile or more to feast on aggregations of squid and roam across large swaths of the Pacific to avoid depleting their food resources in any one area.

On a Mission

There’s a big difference between casual, submerged sightseeing — happy-snapping pictures of whatever you run across while blowing bubbles — and diving dedicated to carefully searching select sites, sometimes during […]

Celebrating Seagrass

The benefits of protecting seagrass cannot be overstated. Seagrass purifies the water, helps protect against coastal erosion, helps sustain small-scale fisheries that support communities, and increases fish populations and biodiversity. It sequesters much more carbon per area than terrestrial forests and reduces ocean acidification. Healthy seagrass means a healthier ocean.

Shore Thing

Aside from allowing me to avoid that sunrise alarm, shore diving offers other freedoms as well: the last-minute choice of a dive site, the ability to do a two-hour dive without worrying a boat crew and the liberty to add a dive to my day if conditions allow. As an added benefit, beach diving can be quite economical compared with boat diving. And some of the most incredible sites in the world are most easily dived from the beach
