Category: Underway Data Format

CalCOFI cruises collect underway data on NOAA vessels from the SCS (Shipboard Computer System). These data may or may not be combined into a common, comma-delimited, ascii file. Most sensor data are collected at different frequencies and require post-cruise processing to combine into a standard time frame. RV New Horizon’s underway dataset may be a…

SIO vessels collect MET (meterological system) underway data. These data include surface TSG measurements combined with fluorometry, pH, ship instrumentation (such as heading & speed) & meterological data. These values may be combined into 30 second records and collected into daily files. CTD near-surface data are used to correct underway temperature, salinity, & fluorometer measurements. Underway…

CalCOFI cruises on SIO vessels, particularly RV New Horizon, collects underway data recorded by the MET (shipboard meterological) system. Every thirty-seconds, a record of surface measurements (T, S, Fl, pH), ship measurements (speed, heading, Ashtech, winch, PDR, & more), and meterological measurements (wind, surface PAR, barometer, & more) are combined into a single, comma-delimited record.…
