******************************************************************************************************************* UH-CODAS POST-PROCESSED SHIPBOARD ADCP DATA COLLECTED BY THE R/V MIRAI DURING RESEARCH CRUISE CINDY LEG 2. THE PROCESSING USED SINGLE PING (ENR) DATA, TOGETHER WITH HEADING AND POSITION ANCILLARY DATA. FOLLOWING STANDARIZED CORRECTIONS TO THE REFORMED VMDAS ADCP DATA, A VISUAL EDITING WAS PERFORMED IN THE ENTIRE DATASET TO FLAG BAD DATA. ALL UH-CODAS SOFTWARE WERE OBTAINED FROM http://currents.soest.hawaii.edu/ Output files (ascii format): mr1107b_sadcp_u.asc (eastward component of velocity) mr1107b_sadcp_v.asc (northward component of velocity) 5 minute average data Format: Firt row: First column, dummy (set to 0.0), Subsequent columns, depth in meters Subsequent rows: First column, Decimal Day (i.e. 0:00 Jan 1, 2011 = 0) Subsequent columns, velocity component (m/s) at depths given in row 1 Absent data set to -99 PROCESSOR: Saulo Soares (saulo@hawaii.edu) BELOW ARE SOME DETAILS OF THE CODAS PROCESSING STEPS: --------------------------------------------------------------------------------------------------------------------- LAST CHANGED : 2012/10/09 01:41:34 CRUISE NAME(S) : mr1107L2_os75 CRUISE DATES : 2011/11/29 18:26:10 to 2011/11/13 01:38:32 SHIP NAME : Mirai PORTS : Colombo, Sri Lanka to Colombo, Sri Lanka CHIEF SCIENTIST : unspecified DATABASE NAME : aship DATA FILES : zzz2011_301_00004.raw to zzz2011_333_80794.raw STATUS : to do done ------ ----------- averaged [ x ]!reformed vmdas loaded [ x ] NOTE: No automated time-dependent heading correction exists check heading correction [ x ]!No heading correction device calibration [ x ]!Applied rotation angle and amplitude corrections using shorter timefiltering. edited [ x ] re-check heading correction [ x ] check editing [ x ]!
