SurfaceMooringInstrumentDataSummaryCAMDS Digital still camera Very little data, software incomplete, frequent hardware failures,

late procurement & poor quality

OPTAA Optical attenuation and absorption No battery, so turns off if mooring fails. Long service interval so often not deployed. Significant biofouling.

FDCHP Air-sea Flux direct covariance Frequent instrument hardware failures, late procurement

NUTNR Dissolved nitrate Frequent instrument hardware failures, significant biofouling

PCO2W Aqueous partial pressure carbon dioxide Finicky instrument, so major setup problems, now OK

VEL3D High-frequency 3D point velocity Mooring software was unable to operate sensor until recently

ZPLSC Zooplankton sonar Late procurement, occasional hardware or configuration failure, calibration under development

PCO2A Air and sea partial pressure carbon dioxide Significant fouling on buoys, but now mitigated

PHSEN pH Finicky instrument, so some setup problems, now OK

ADCPT/S Acoustic Doppler current profiler Occasional instrument hardware failure or battery miscalculation

CTDBP Conductivity, temperature, pressure Occasional battery miscalculation Some biofouling

DOSTA Dissolved Oxygen, stable (vs. fast DOFST) Significant biofouling

FLORT Florescence (chlorophyll-a, optical backscatter, CDOM)

No battery, so turns off if mooring fails Some biofouling

METBK Bulk meteorology (short & long wave radiation, air pressure, temperature, relative humidity, wind, rain)

Occasional instrument hardware failure

PRESF Bottom pressure No problems

SPKIR Spectral irradiance No battery, so turns off if mooring fails Some biofouling

VELPT Mean 3D point velocity Occasional instrument hardware failure or battery miscalculation

WAVSS Wave spectra No problems in buoy and on ISSM MFN
