Real Time Data
Real time data is sent back to shore by several subsystems on the buoy.
Argos transmitters relay met data from the two ASIMet loggers
on the buoy, and a subsurface telemetry system, consisting of an
inductive modem transmitting via Iridium, sends back data from several
instruments on the mooring line. Links to near-real-time data are on
the right-hand column of this page.
NTAS data is also available from the OceanSITES THREDDS server at NDBC.
The fifteenth NTAS buoy was deployed from the R/V Endeavor on February 2, 2016.
Hourly meteorological data for the current deployment of the NTAS buoy are recieved via Service Argos four times daily. Data is displayed as time series and available for download as ASCII files a well as OceanSITES NetCDF files.
The NTAS 15 subsurface telemetry system used an inductive subsystem developed at WHOI, and transmitted via an Iridium modem.
The inductive modem transmits data from 5 SBE 37s and a single current meter. A record time is provided by the Seabird Inductive Modem (SIM) and represents the time of receipt of the last sample by the SIM. To adjust the time word in the Iridium data stream, we have subtracted 30 minutes, so time is approximately at the center of the hourly sample.

The instruments are sampled once per hour. The ID# controls the position of the instruments' data within the Iridium message.
The NTAS buoy is equipped with an NDBC WAMDAS Wave system. The wave data is available at NDBC's Station 41060 page.
