RV Investigator Voyage IN2018_V02 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2018_V02, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania; Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site." The voyage took place between the March 3 and March 21, 2018 departing Hobart (TAS) and returning to Hobart. Data was collected during in2018_v02 for the entire duration of the voyage. Data was collected using UHDAS and post-processed using CODAS. The os150(150kHz) ADCP was not operational during this voyage. The os75(75kHz) was run for the entire cruise. The ADCP was operated in narrowband mode with 8m bins for the duration of the voyage. Internal triggering was used as external triggering was found to be unstable on previous voyages. The drop keel was at 2m for most of the voyage. It was raised to flush with hull on the 13th of March at 0118. UHDAS logging was not restarted till 0422 resulting in several hours of bad data. See the voyage computing and electronics report for more details regarding data acquisition.This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart.
