Global Reef Expedition: Mission to Tonga

the point intercept surveys. In this sampling technique, a scientific diver used a 1 m × 1 m quadrat, flipping it over a total of 10 times per transect to capture detailed photographs of a full 1 × 10 m photo transect. Analyzing photos of the underwater landscape required using computer software called Coral Point Count with Excel Extensions (CPCe), which was developed by our partners at Nova Southeastern University’s National Coral Reef Institute (NCRI). The images were imported into the software, where 50 random points were overlaid on each photograph. A scientist then defined

is no toy, the components are very well made and the ROV’s capabilities rival more well-known products which cost many times more. It is a kit and some skills are required to complete it. But if you are able to use a few simple hand tools, follow written instructions and install and configure computer software, you have all the skills required to build this kit. I would say the greatest challenges for the builder are the topside controller and dealing with the software/firmware, but even these tasks are not very difficult. And building the kit yields an additional benefit, that when it comes time

ever of its type - was carried out beneath the waves. Subsea, air and saturation divers first marked out the structure, using 3,000 magnetic, coded markers, and then some 20,000 high-definition, overlapping photographs were taken over a 70-day campaign. The photographs were then converted, using computer software, into an exact geometric 3D model, using the information from the markers, from which the K-nodes and conductor level guide could be designed. Next, inspection work, surface cleaning and preparation work had to be done, including underwater grit-blasting and measuring member wall thickness
