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. [1]

Purpose

The SVII camera was designed as a replacement for its prototype predecessor, the SVI, [2] 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. Additionally, the images will be made available by Google using the Google Maps Street View platform, to increase public awareness of the risks faced by coral reefs. [3]

The SVII is based upon its prototype, the SVI. Both cameras are self-propelling underwater housings for a set of three Canon 5D cameras using wide-angle lenses. [4] With a top speed underwater of about 3–4 kilometres per hour (1.9–2.5 mph), the cameras record an image every 3–6 seconds and associate them with a geolocation coordinate. [3] The images are then stitched together to create a 360-degree panorama of the area, in a format which can be uploaded online for public viewing.

The SVII is controlled by a Samsung Galaxy Tab tablet to permit the user to change settings, and download or view images. [1] The improved design also allows users to recharge the camera more easily and quickly than with the SVI. While intended for more widespread use, there are currently four SVIIs in existence.

The SVII was invented and developed by Underwater Earth, in collaboration with Panedia and manufactured by ClaroWorks, the product development side of Dive Xtras. The SVII uses some technology developed by Dive Xtras / ClaroWorks; such as the underwater tablet housing and vehicle.

Great Barrier Reef Coral reef system located in the Coral Sea in Australia

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 100 miles wide in places and over 200 feet deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006.

The island is situated on the leeward (western) side of Heron Reef, a fringing platform reef of significant biodiversity, supporting around 900 of the 1,500 fish species and 72% of the coral species found on the Great Barrier Reef. During the summer months Heron Island is also home to over 200,000 birds including Noddy Terns and Mutton Birds.

Coral reef protection Modifying human activities to reduce impact on coral reefs.

Coral reef protection is the process of modifying human activities to avoid damage to healthy coral reefs and to help damaged reefs recover. The key strategies used in reef protection include defining measurable goals and introducing active management and community involvement to reduce stressors that damage reef health. One management technique is to create Marine Protected Areas (MPAs) that directly limit human activities such as fishing.

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.
