Whats Inside:

Rouse Simmons
During the 19th century, believe it or not, Chicago was one of the busiest shipping ports in the world. In 1875, nearly 21,000 vessels passed through Chicago’s harbor. Great Lakes ships carried nearly every commodity needed in the bustling city, and Christmas trees were no exception.
New Cave – Old Species
Dominican Republic Cave Exploration
We were invited to the Dominican Republic by Gri Gri Divers to assist in the discovery and exploration of their local caves.  Gri Gri Divers, located in Bayahibe, manages all the dive programs for the local resorts. 
Zrmanjin Zov
On July 29th, Jean Jacques prepares for the exploration of the big cave at -120 meters, but at the lake we are disappointed to learn that visibility is down to about 50 centimeters. some six thousand smaller skerries.
Ricks Spring
In March 2007, Wendell and Richard made it in through the very tight entrance of Ricks Spring for the first time. Ricks is definitely side-mount access only. There are some very large passages, but also some restrictions that won’t allow for back-mount access.
Mystifying Leviathans of Cay Sal
As we descended further, the reef melted away to raw rock. We had reached a depth where light and the current could no longer provide for extensive life. Even here, we found lobsters taking advantage of the recesses that the walls afforded. Swimming along felt like being weightless in a great canyon.

B-24 Liberator The “DRIP”
With almost no clouds, the silver B-24’s were clearly visible in the sky, even at 7000 meters. So it didn’t take long before they were spotted by the ground flak gun crews who hurried into action, attacking the formation with grenades.
Wreck Fest 2009
Aside from the usual wreck dives like the Spiegel Grove and the Benwood, we were able to dive some of the less visited deep wrecks such as the Northern Light, Doc DeMilly, and Queen of Nassau.
Tech Video
Whether you intend to bring home the best vacation video or are thinking about making a big break into underwater television, here are a few things to think about before taking a camera on a technical dive.
Prince Rupert Expedition
