Choosing Mirrorless Cameras for UW Photography

While the number of camera manufacturers with horses in the mirrorless race has now reached critical mass with the recent entrance of Canon and its EOS-M, and the earlier entrance of Nikon with the J1 and V1 cameras, the number of models available has grown even more. However, for underwater photography the choices narrow somewhat and the early entrants in the mirrorless race, Olympus, Panasonic and Sony, are very much in the lead.

The Clock — Extend dive time with physical fitness

Tick tock tick tock. Have you ever heard someone say, “There goes 15 minutes of my life I will never get back?” While there are many different philosophies and applications of time, most divers don’t want to waste it. Instead, divers carefully invest some of their precious time, energy and money planning and preparing for their ideal SCUBA experience.

Help keep an eye out for spotted eagle rays

In 2009, Mote Marine Laboratory with the National Aquarium in Baltimore initiated a conservation research program on the life history, reproduction, and population status of the elasmobranch Aetobatus narinari, commonly known as the spotted eagle ray To identify where these rays migrate, Mote has tagged animals with traditional tags and with satellite tags that allow the rays’ movements to be followed as they travel.

We don't know if the rays in the Keys come from Southwest Florida, or perhaps even Mexico or Cuba, and we don't know if rays in the Keys favor particular reefs

Apollo rocket engines recovered from the Atlantic abyss

The F-1 was a workhorse engine for the US space agency NASA as the most powerful single-chamber liquid-fuelled engine ever developed.

Because the engines' serial numbers are partially missing, it remains unclear which Apollo mission they are from - that may become clearer during restoration.

What do vampire squids eat (it's not what you think)

The vampire squid (Vampyroteuthis infernalis) is a small, deep-sea cephalopod found throughout the temperate and tropical oceans of the world. It's easy to imagine the vampire squid as a nightmarish predator. It lurks in the eternal midnight of the deep sea, has a dark red body, huge blue eyes, and a cloak-like web that stretches between its eight arms.
