|Austin and Pat load the DTS cable onto Atoll-1|
Today we deployed the first 1 km section of fiber optic cable on the Dongsha reef between the lagoon and our scaffolding tower. Though it presented some challenges, we all made it through in one piece (especially the cable). The next step is to deploy another 3 km of cable to stretch from the lagoon all the way towards the open ocean to the forereef. During the next weeks the 4 km of cable that lies on the reef will collect accurate temperatures within 0.01°C every meter at 30 second intervals. These measurements will allow us to track the cold water brought to the reef by internal waves (see the "Science" section). All of this is accomplished using a technology known as DTS.
Tom swims behind Atoll-1, carefully laying cable across
the reef. The scaffolding tower that will hold the solar panel
and electronics is in the background.
