Seaview SVII
The Seaview SVII is an underwater camera designed by the Catlin Seaview Survey team, intended to photograph coral reefs to provide visual documentation of a reef's health. The camera is designed to be controlled by a diver in shallow waters, and is propelled at a constant slow speed by a propeller mounted near the rear of the camera. Only two SVIIs are currently in existence. The cameras were used by the Catlin Seaview Survey and Google to create Google Ocean, a means of displaying underwater images using Google's existing Street View platform. Purpose The SVII camera was designed as a replacement for its prototype predecessor, the SVI, to take thousands of images of the shallow waters of the Great Barrier Reef and other endangered coral reefs around the world. The imagery and data generated by the camera and its operators is intended to provide a visual record of the health of the reefs, creating a baseline record for the reefs' health to be compared to future surveys.

Catlin Seaview Survey
The Catlin Seaview Survey, later renamed the XL Catlin Seaview Survey, was a major scientific expedition which commenced in September 2012, whose aim was to document the composition and health of coral reefs worldwide. Specifically, the survey aimed to "carry out a rapid assessment of the current state of coral reef systems and to make this scientific record publicly available for scientists worldwide to use". The survey was sponsored by the Catlin Group until the survey ended when the Catlin group ended sponsorship. The original team created a film, chasing coral and a new, global initiative known as 50 reefs. History The survey started in September 2012, and was focused on sections of the Great Barrier Reef across a range of depths. Specifically, 32 reefs were sampled, which equated to approximately of reef. This produced around 105,000 images, which are currently being analysed by scientists globally, using image recognition software. In addition to imaging shallow reefs, th ...

Hanauma Bay
Hanauma (; ) is a marine embayment formed within a tuff ring and located along the southeast coast of the Island of Oahu in the Hawaii Kai neighborhood of East Honolulu, in the Hawaiian Islands. Hanauma is one of the most popular tourist destinations on the Island and has suffered somewhat from overtourism. At one time, this popular tourist destination accommodated over three million visitors per year. In 1956, dynamite was used to clear portions of the reef to make room for telephone cables linking Hawaii to the west coast of the US. Name The prefix ''hana'' means bay in the Hawaiian language (the usual addition of bay in its name is thus redundant). There are two etymological interpretations of the second part of its name. One interpretation derives it from the Hawaiian word for curve, referring to either the shape of the feature or to the shape of the indigenous canoes that were launched there. Another stems from the indigenous hand-wrestling game known as "Uma". Marine lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dive Xtras
Dive Xtras is a manufacturer of diver propulsion vehicles (DPVs) or dive scooters in Mukilteo, Washington, United States. History Established in 2003 by Ben McGeever and Andrew Georgitsis, Dive Xtras introduced their first DPV in 2005. This DPV was innovative in that it was the first to utilize a Brushless DC electric motor, brushless motor and electronic speed control. The combination of these features with Nickel-metal hydride battery, NiMh battery technology drastically reduced the weight of DPVs at the time. In 2017, Dive Xtras introduced the use of Lithium-ion battery, Li-ion power tool batteries (PTBs) for their Piranha line, which became standard for their later BlackTip and CudaX scooters. Models * Sierra Std - The Sierra standard body X-Scooter is the lightest scooter in the Dive Xtras family. * CUDA 400 - NiMh version of the CUDA Fury 1150 (aka mini CUDA). * CUDA 550 - The first "CUDA". Slightly shorter than the 650. Used a 550 watt hour battery pack. * CUDA 650 - Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
