SLGO is the first integrated ocean observing system in Canada.
As an example, UNESCO (2010) has defined a series of quality flags for water temperature and salinity data (Global Temperature-Salinity Profile Program – GTSPP) 1. In this case, quality codes are integers between 0 and 9.
|0||No quality control has been assigned to this element|
|1||The element appears to be correct|
|2||The element appears to be probably good|
|3||The element appears doubtful|
|4||The element appears erroneous|
|5||The element has been changed|
|6 to 8||Reserved for future use|
|9||The element is missing|
Units associated with each variable should be clearly noted. As an example, the Environmental Data Management System references section on the SLGO portal provides a description of units used for a wide range of environmental variables from athmospheric pressure to dissolved oxygen concentration.2
