Definitions of Selected Terms, This manual contains several terms whose meanings are critical to those using the manual These terms are. included in the following table to ensure that the meanings are clearly defined. Codable Instructions Specific guidance that can be used by a software programmer to design. construct and implement a test These instructions also include examples with. sample thresholds, Data Record One or more messages that form a coherent logical and complete observation. Dissolved Nutrients A generic reference to a sensor used to measure one or more specific dissolved. DN Sensor nutrients such as NO3 NO2 NH4 PO43 SiO43 Ptot or Ntot No. single sensor is capable of measuring all dissolved nutrients for a number of. dissolved nutrients no sensors are available, Message A standalone data transmission A data record can be composed of multiple. Operator Individuals or entities responsible for collecting and providing data. Quality Assurance Processes that are employed with hardware to support the generation of high. QA quality data section 2 0 and appendix A, Quality Control Follow on steps that support the delivery of high quality data requiring both.
QC automation and human intervention section 3 0, Real Time Data are delivered without delay for immediate use time series extends only. backwards in time where the next data point is not available and sample. intervals may range from a few seconds to a few hours or even days depending. upon the variable section 1 0, Sensor A device that detects or measures a physical property and provides the result. without delay, Thresholds Limits that are defined by the operator. 1 0 Background and Introduction, The U S Integrated Ocean Observing System IOOS has a vested interest in collecting high quality data for. the 26 core variables U S IOOS 2010 measured on a national scale In response to this interest U S IOOS. continues to establish written authoritative procedures for the quality control QC of real time data through. the Quality Assurance Quality Control of Real Time Oceanographic Data QARTOD project addressing. each variable as funding permits This dissolved nutrients DN data manual is the eighth in a series of. guidance documents that address the QC of real time data for each core variable.
