Effective ocean and coastal data management are needed to manage marine ecosystem health. Past systems were often very specific a particular application region, but this focused approach lacks real-time sharing/interoperating capability. The challenge for the observing community is devise standards practices that enable integration of from sensors across devices, manufacturers, users, domains new types applications services facilitate much more comprehensive understanding analyses ecosystem....
Ocean observing systems may include a wide variety of sensor and instrument types, each with its own capabilities, communication protocols, data formats. Connecting disparate devices into network typically requires specialized software drivers that translate command between the protocols individual instruments, platform on which they are installed. In addition, such platforms require extensive manual configuration to match driver other operational details port specific connected instrument....
The use of marine cabled video observatories with multiparametric environmental data collection capability is becoming relevant for ecological monitoring strategies. Their ecosystem surveying can be enforced in real time, remotely, and continuously, over consecutive days, seasons, even years. Unfortunately, as most perform such fixed cameras, the value their limited to a narrow field view, possibly not representative local habitat heterogeneity. Docked mobile robotic platforms could used...
