Reliability Probability that a specified software or hardware item performs a given task successfully under specified conditions for a specified length of time or number of cycles. Remotely-Operated Vehicle (ROV) A remotely operated vehicle is a tethered underwater robot. An ROV may sometimes be called a remotely operated underwater vehicle to distinguish it from remote control vehicles operating on land or in the air. ROVs are unoccupied, highly manoeuvrable and operated by a person at a distance. They are linked to the power and communications source by a tether (sometimes referred to as an umbilical cable), a group of cables that carry electrical power, video and data signals back and forth between the operator and the vehicle. Repository A facility providing permanent storage, preservation, disposition, and distribution of information about resources, particularly data and their associated metadata. Resolution (pertaining to instruments/sensors) The smallest amount of input signal change that the instrument/sensor can detect reliably. Resolution (pertaining to spatial or temporal characterization requirements) The capability to distinguish (i.e., resolve) physical, chemical, or biological features within a specified spatial or temporal interval. Resource Reference A link, pointer or bookmark that will indicate the location of a resource of interest, without having to copy it. Role Function to be fulfilled by a particular user. Roles allow granting specific functionality to a certain user or group of users. 101
Sampling (1) Physically extract a given volume of the milieu (with bottle, core, pumping,…) in the laboratory or in an in situ analyser. (2) Get a measurement from the milieu. Sampling protocol The set of rules used to describe scientific measurement, physical sampling and reporting. Scale (1) System of grouping or classifying in a series of steps or degrees according to a standard of relative size; (2) According to a hierarchy. Seafloor The interface between the bottom of the water column and the upper few meters of solid surface beneath it. The seafloor is sampled by instruments on benthic packages and seafloor packages. Seawater ground The return current ground “cathode” for a Primary Node. Seismonument A cement housing that hosts a short-period seismometer that provides coupling to the seafloor. Semantic Metadata Information characterizing the meaning of an entity (often a data set). Sensor A device that will convert a physical phenomenon into an electrical signal that can in turn be digitised through the use of an analog to digital converter. A sensor is normally housed in an instrument. Data coming from sensors is normally raw and needs to be calibrated. 102
