QA of data is performed following manufacturer guidelines for calibration and servicing of each sensor. QC'd datasets that have undergone additional manual inspection by researchers is provided in a 3 month lagging interval. Following the publication of human QC'd data, automated QC'd data from the previous 3 month window will be removed. See the 'Buoy Telemetry: Manually Quality Controlled' dataset for the full quality controlled dataset.The Automated QC of measurements collected from buoy platforms is performed following guidelines established by the Ocean Observatories Initiative (https://oceanobservatories.org/quality-control/) and implemented in R.\n        Spike Test: To identify spikes within collected measurements, data points are assessed for deviation against a 'reference' window of measurement generated in a sliding window (k=7) . If a data point exceeds the deviation threshold (N=2), the spike is replaced with the 'reference' data point, which is determined using  a median smoothing approach in the R package 'oce'.  Despiked data is then written into the instrument table as 'Measurement_Despike'.\n        Global Range Test: Data points are checked against the maximum and minimum measurements using a dataset of global measurements provided by IOOC (https://github.com/oceanobservatories/qc-lookup). QC Flags from global range tests are stored in the instrument table as 'Measurement_Global_Range_QC'. QC Flags: Measurement within global threshold= 0, Below minimum global threshold =1, Above maximum global threshold =2.\n        Local Range Test: Data point values are checked against historical seasonal ranges for each parameter, using data provided by URI GSO's Narragansett Bay Long-Term Plankton Time Series (https://web.uri.edu/gso/research/plankton/). QC Flags from local range tests are stored in the instrument table as 'Measurement_Local_Range_QC'.  Local Range QC Flags: Measurement within local seasonal threshold= 0, Below minimum local seasonal threshold =1, Above maximum local seasonal threshold =2.\n        Stuck Value Test: To identify potential stuck values from a sensor, each data point is compared to subsequent values using sliding 3 and 5 frame windows. QC Flags from stuck value  tests are stored in the instrument table as 'Measurement_Stuck_Value_QC' QC Flags: No stuck value detected= 0, Suspect Stuck Sensor (3 consecutive identical values) =1, Stuck Sensor (5 consecutive identical values) =2.\n        Instrument Range Test: Data point values for meterological measurements are checked against the manufacturer's specified measurement ranges. QC Flags: Measurement within instrument range= 0, Measurement below instrument range =1, Measurement above instrument range =2.\n\ncdm_data_type = Other\nVARIABLES:\ntime (Datetime, seconds since 1970-01-01T00:00:00Z)\n...

When phytoplankton are under stress, the rate at which they fluoresce can be decoupled from the rate of photosynthetic productivity.
