All of today was dedicated in preparation for our first stop. Our estimated time of arrival is early tomorrow morning at 3 am. Several things needed doing. The spare CDT cable was finished off with some heat shrink and a final coat of scotch coat sealer; and the communications between the head unit and device was checked.
I was given a tour and complete breakdown of the ships networks. The ship is a maze of network wire with terminals in every corner of the vessel. The ship has two networks, one for general use by the science and ship’s crew. The second and most important is the network for all the science equipment/computers that collect data.
All of the major pieces of equipment talk to one another through his second network. The three GPS (global positioning satellite) systems, ADCP (acoustic Doppler profiler) , CTD (conductivity, temperature, and depth), and the meteorological sensors are all tied in on this network. The data is gathered and displayed on several different screens and also recorded for later use.
Today I also completed a second draft of a maintenance manual for the Benthos acoustic pinger. The manual highlights best practices and things to know when working on maintaining the device.
