CTD Asc Filename Change Print Email
Written by JRW

CTD asc filenames have typically been 'd or u' YYMMPPP.asc & .hdr (d or u = down or up casts; YY is year; MM month; PPP order occupied or proc #).  To standardize the file naming, the .asc & .hdr will be renamed to match the bottle-corrected csvs, YYYYMM_LLLLSSSS_PPPud.*, where YYMM is year month; LLLLSSSS is decimal Line & Sta (minus the '.'); PPP is order occupied (or processing number); u or d for up or down.

CTD Asc Format Change Print Email

Voltage column headers in .asc files will be converted from "V0  V1  V2..." to sensor-specific labels.  If V0 is transmissometer then the column header will be changed from "V0" to "TransV".  Since the sensors can be mounted on different voltage channels on different cruises (or even the same cruise), this labeling scheme is important for easily distinguishing the sensor voltages.  JRW 06/30/2009

New(er) Beckman LS 6000IC (SysID# 231220) scintillation counter donated to SIO-CalCOFI by NOAA in early 2008.  Repaired by SIO-CalCOFI and in service Oct 2008,  replacing our broken/non-repairable Beckman LS 1801.
  • First cruise counted on new counter: 0810NH
  • New productivity import routine (DECODR, in-house data processing suite) written to ingest the new file format. Replicate 14C uptake calculations compared between old and new Beckman counters; agree within 95% CL.
