Evenings at Whitney Public Lecture Series - April 8th, 2010 - Summary of “Ocean acidification: the other shoe for climate change. What could happen, what is likely, and what should we be doing?” Andrew Stamper, D.V.M., Dipl. A.C.Z.M., Epcot, The Seas.
When considering conservation of the ocean, one of the things we don’t often think about is the pH level in our oceans and how it affects our aquatic life.
Just as the ph of a swimming pool affects our eyes and skin, the ph in the ocean affects the creatures living in it. For those of you that have ever cared for an aquarium or a swimming pool, you may notice that even minute shifts in ph can cause marked changes in your water quality.
Can you imagine what would happen if you dropped the ph by 30% in your pool or aquarium? Water quality would drop dramatically and when this happens in the ocean, the regulating enzymes within the marine live would go up or down, which is within the physiology of most creatures but at the costs of valuable energy. The short-range changes would be adaption, and long-range successful adaptation is called evolution. Continue reading for more on this important topic.
Frogfish diving adds Nimar housings to their range
UK company Frogfish Photography has added Nimar underwater housings to its range of underwater photography brands. Nimar housings are relatively affordable and models are available to suit many different SLRs. Nimar has been around for over 20 years and has been manufacturing housings for both video and still cameras in northern Italy since the early 1980s. They have just introduced a stylish black polycarbonate housing to sit alongside their existing clear version. Frogfish Photography has a demonstration model for customers to play with and can arrange for try outs in the pool.
Frogfish Photography is having a busy year with the Visions in the Sea series of underwater photography workshop weekends planned over the summer. They also have an exhibition of their work on display in Manchester in May. Lastly, they are planning a trip to South Africa later in the year.

Sigma 8-16mm zoom lens available at the end of April
Sigma has announced the availability date of its new 8-16mm f4-5.6 DC HSM ultra wide angle zoom lens.
The new lens is designed to fit dSLR cameras with APS-C size image sensors and is the first zoom lens on the market with a minimum focal length of 8mm. The lens is equivalent to the 12-24mm on full frame with an angle of view starting at 121.2 degrees.
The lens combats color aberration using four FLD (“F” Low Dispersion) glass elements, which the company claims performs equal to fluorite glass. One hybrid aspherical lens and two glass mold elements provide distortion and astigmatism correction. The Super Multi-Layer Coating reduces flare and ghosting.
The Sigma 8-16mm f4-5.6 DC HSM incorporates HSM (Hyper Sonic Motor) and has a minimum focusing distance of 24cm throughout the entire zoom range. Its overall length is 105.7mm with a maximum diameter of 75mm. It will hit the stores at the end of April with Sigma, Canon and Nikon fit first, followed shortly by Sony and Pentax versions
Dive fest 2010
The second annual Dive Fest is to be held at Pentewan Sands Holiday Park over the weekend of 30th April to 3rd May. The idea is that divers from all over the UK get together for a huge party, complete with live music, food, events and equipment and travel stalls. The first such event took place in May 2009 and was a massive success, with more than 1,000 divers attending.
During the festival, images from the British Underwater Image Festival will be on display, and the awards ceremony for the competition will take place on Sunday. In addition, Dive Fest will host a splash in competition, with prizes for the best images taken on that day.
Other events include talks from Sea Shepherd and the Sharks Trust, live bands, curry nights, and RIB or hard boat diving throughout the weekend.

2010 NAB Show report, Las Vegas
Last week, I decided that it would be interesting to check out the NAB Show, an annual tradeshow in Las Vegas put on by the National Association of Broadcasters.
As a NAB Show newbie, I wasn’t sure what to expect; I knew that it would be different from the dive shows I typically attend, but I wasn’t prepared for just how different it ended up being. Everything was shiny, slick, and professional, and there were quite a few people wearing suits. I didn’t see any flip flops or swimsuits, and no one was serving rum from beneath fake tiki huts…
