Description of cabled observatories is concise in the lead paragraph and I think it could use expansion and clarification, particularly on characterizing research platforms. Further expansion should detail the functions of a typical cabled observatory, what research platforms can be used, and what innovations could be developing from this technology. The description of the cables themselves is good, and I think a section detailing recent development in the cables could be relevant. Cable design and key functions could be good to summarize and include. Also featured is a list of cabled observatories, with some entries leading to informative articles, a few leading to stubs, a few leading to articles that are inaccessible, don’t exist, or are not linked to articles.the list could perhaps include summaries of teach entry. A history of cabled observatories and recent developments made by cabled observatories would be good to find and include. Finally, pictures or visuals would help the reader quickly understand the subject. |

 | This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

A cabled observatory is an oceanographic research platform connected to land by cables that provide power and communication. Observatories are outfitted with a multitude of scientific instruments that can collect many kinds of data from the seafloor and water column.[1][2] Data from these instruments is relayed to a land station and data networks, such as Ocean Networks Canada, in real time.[1][2]
On-board sensors
[edit]Cabled observatories have the benefit of high-power cable connections that can support a variety of instrumentation at any time. Such instrumentation can include cameras and microphones that can take high-definition audio and video, standard sensors that measure pressure, temperature, oxygen content, conductivity, turbidity, and chlorophyll-a fluorescence, and custom sensors for specialized purposes.[1][2] Over 200 instruments can be installed on a cabled observatory at a time, as seen on the NEPTUNE and VENUS observatories.[3]
Comparison with other data collection methods
[edit]Cabled observatories are ideal for use in complex regions of the ocean where continuous data sampling is required for understanding the area of interest. Such areas include the complex biospheres of the temperate coasts and polar regions, which are sensitive to climate change.[2] Conventional methods for oceanographic data collection, such as by ship, are often limited by the harsh typical weather conditions and cannot sample data continuously.[2] Mooring systems have also been a common method for long-term ocean data sampling, however they require scientific cruises for scientists to receive data or to discover damage to the mooring system and carry out repairs.[2] Data collection by ship and by mooring system in complex or harsh environments has historically led to data losses and inaccurate conclusions.[2] By eliminating the need for regular ship use and bolstered with extensive sensor sets, enabled by direct power connections, cabled observatories have the capability to provide continuous and detailed data sampling for regions of the ocean that are otherwise inaccessible.[2]
Usage locations
[edit]Cabled observatories are permanently fixed in one area and cannot take measurements beyond that area, however they can support sensors and apparatuses that can travel vertically in the water column and observatory data can be combined with ship data to create a more complete understanding of the area as well.[2] An observatory can be placed as far as 300 km from shore if the conditions permit.[4] Observatories can be placed in waters as deep as 2500 meters and as shallow as 10 meters, even when the wave height is greater than the water depth.[2][4]
Operation Limitations
[edit]Many issues involving data reliability and loss have arisen and been investigated by teams running cabled observatories. Such issues include data loss, sensor failure, and data reliability issues. The sources of these issues are diverse, with common causes being improper operation, biofouling, cable connection issues, and leakages.[2] Additionally, data loss can occur from improper installation or operations of sensors and data management, which are more likely to occur if those responsibilities are taken on by research groups external to the observatory team. This issue prompted the usage of streaming of final probe data to communicate data to partner research groups for the COSYNA observatory team, and streaming is now a common method for data communication for other observatory teams.[2][4]
