Meet the Team:

Jeff Webster, Production Jeff was born in San Diego, but grew up on the islands of Oahu and Hawaii. After attending Konawaena High School in Kona, Hawaii, Jeff served for four years in the U.S. Army as an infantryman and helicopter mechanic. During his tour of duty, he was stationed in Hawaii and Kentucky. Jeff joined the DeepSea production team in 2004. In addition to expertly building DeepSea products, Jeff operates the manufacturing pressure test facility, verifying the integrity of products before they ship. In his off hours, Jeff enjoys art, especially the use of color pencils and watercolors. The images that emerge from his hand often portray an idyllic Pacific island life in a variety of intriguing styles. You can see samples of Jeff's artistic work at http://www.deepsea.com/Jeffsart.html ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Dimming Option Now Available for Low-voltage LED Multi-SeaLite® Matrix and LED Mini-SeaLite® The new LED Multi-SeaLite® Matrix is available with either a high voltage AC/DC driver or a low voltage DC driver. The LED Mini-SeaLite® is available with only a low voltage DC driver. Either light's low voltage DC driver is now available with a smooth flicker-free constant current dimming control using a 0-5vdc analog control line.

SeaBattery(TM)Awarded ABS Type Approval

This is good news. Thanks to the encouragement of Bill Crowley, Cal Dive, (New Iberia, Louisiana), and months of effort between DeepSea and ABS, offshore projects that require ABS Type Approved underwater batteries can now be handled with one phone call. DeepSea Power & Light®'s SeaBattery® is now ABS Type Approved for use at sea on projects requiring ABS certification. They are the only pressure compensated battery with the ABS Type Approval designation. In addition to the new ABS applications, SeaBattery has shown its capacity for daring exploit by freefalling to the bottom of the Tonga Trench, more than 35,000-ft, as part of an autonomous ocean trench research vehicle, then free ascending on a return trip to the surface. The OceanLab Hadal Lander is operated by the University of Aberdeen OceanLab (Newburgh, Scotland), directed by Dr. Alan Jamieson, Research Fellow. The Hadal Lander is powered by a single 12-volt, 28-Ah SeaBattery that provides 12 hours of autonomous operation. Further information on the Hadal Lander is found in the story, "Imaging Deep-Sea Life Beyond the Abyssal Zone," which appeared in Sea Technology, March 2009, pp 41-46.

Undersea Voyager Project Dives Lake Tahoe

Lands in USA Today Scott Cassell, Founder and Chief Submersible Pilot of the Undersea Voyager Project (UVP), led a team of submarine explorers to Lake Tahoe to study lake pollution, survey earthquake faults, and hunt for ancient submerged trees that grew as long as 3000 years ago during a period of great drought. Though the submersible was limited to 150-ft of Tahoe's 1,645-ft depth, it transited a combined 100 miles of bottom landscape during its many dives. Scott says "I used DSP&L lights and camera for several live sub-to-surface broadcasts including to a local news station, Good Day Sacramento and FOX news. The live feed concept from the UVP mission is a success and will be an integral part of what is to come. And what is coming is going to be BIG!"

17-inch glass sphere tested in DeepSea's 20-inch Pressure Chamber

A team of deep ocean biologists from Scripps Institution of Oceanography/UCSD directed by Dr. Douglas Bartlett, recently tested a 17-inch Vitrovex 9km-rated sphere with multiple feedthroughs in DeepSea Power & Light's 20-inch pressure chamber. The sphere was being qualified for operation in the Puerto Rico Trench, where depths can reach 8400m. The sphere was successfully taken to 12,750-psi, equivalent to 8750m. The sphere is part of a free vehicle that gathers 60-liter water samples from the benthic boundary layer 2m above the trench floor. A secondary module can collect surface sediments for further microbial studies. "The test was particularly useful in confirming the integrity of the sphere which experienced some minor spalling during its deployment to 8400m last year," said the researchers. "DeepSea was very helpful in getting our project in on short notice, and built the frame to hold the sphere in the chamber. One of our team was present to witness the test. The chamber operator followed our requested pressurization and depressurization schedule quite closely."

Nice Comments about DSPL 1. DSPL's article "Ocean Engineering 101-Anodizing"

(Ocean News & Technology, April/May 2009), prompted Scott Bentley, President, VideoRay, to forward it to all members of his management and engineering teams with the comment, "This is an excellent article - please consider it mandatory reading and reference material." See a reprint of the story on-line at DeepSea's website under "Technical Library." 2. DSPL supported the 10th International Sub Races (ISR) with underwater video cameras and cables. Carderock Test Basin's Peter Congedo, who helped ISR event organizers, said "Thank you for the underwater cameras you provided. The images they are collecting are being streamed live to DOD sites around the world. The race closes today, new world records were set, and this race was a complete success thanks in large part to you folks. Attendees included many students, engineers, two shuttle astronauts, and various local and national networks. The DeepSea banner was displayed next to the press booth. Thanks again. You run one very classy company." 3. Customer Support: Rodger Martin, a PE at Portsmouth Naval Shipyard was reviewing their in-house procedures for handling SeaBatteries. A few questions came up, and Kevin Hardy and Pedram Pebdani jumped in to sort them out. Rodger wrote back, saying in part, "Kevin/Pedram, thanks again ... You two have been very helpful. Pictures definitely did the trick!!! I'm talking with another fellow in San Diego. ... <He> has also spoken with a few folks at DeepSea and has been very pleased with the assistance you guys have provided. Great to experience this and to hear our folks in San Diego are experiencing the same!!! Talk to you soon. Thanks again for the pictures."

Polaris Sailing Club

DSPL's Kevin Hardy was invited to speak by Ms. Alva Shaefer, Program Chair for San Diego's Polaris Sailing and Power Boat Club. The presentation, titled "Underwater Lights: From Titanic to Friday Evening," illustrated the wide variety of underwater lights made by DeepSea Power & Light, from manned submersibles to small boat thru-hull lights. Kevin pointed out the same care and attention to detail is put into every light made at DeepSea. The PowerPoint presentation opened the audience's eyes to the possibilities of Thru-Hull SeaLites®, and the light demonstrations had them squinting. Interesting questions were asked, including appropriate models of Thru-Hull SeaLites® for sail boats, which have to contend with compound curves. The audience was very engaged, and invited Kevin to return for a second presentation.
