CSIRO Code (CSCB) 631 'Act_Code ' 'ACT ' 'DC ' Station was checked by duplicate checking software 6 'Act_Code ' 'ACT ' 'DU ' Duplicate Drop, CSIRO Code (CSCB) 4 'Act_Code ' 'ACT ' 'EF ' Eddy / Front / Current. Eddies, oceanic fronts and currents are common meso scale features in the oceans. An eddy, front or current appears as an increase/decrease in temperature over large depth ranges when compared to a neighbouring profile. A temperature displacement can sometimes be seen in alternating or sequential drops as the ship track crosses a current, eddy system or frontal region. Confirmation of the feature is established if neighbouring (usually repeat) profile pairs each side of the front show similar temperatures at depth. Temperature sections along the ship track can be used as further evidence these features are real. CSIRO Code (CSCB) 34 'Act_Code ' 'ACT ' 'FS ' Fine structure error: leakage, PET fault, cusping, sticking bit. The temperature profile exhibits erroneous fine structure when compared to neighbouring profiles and/or climatology and/or known characteristics of the region. (The reasons could be signal leakage, XBT recording system failures (sticking bit, cusping, PET Fault, etc), complete instrument failure, etc) 23 'Act_Code ' 'ACT ' 'HB ' Hit Bottom. When the probe hits the bottom, the temperature trace usually goes isothermal. Contact with the bottom is often indicated by a small horizontal spike or undulation. The spike can be due to overheating of the thermistors or physical contact with the bottom. Data recorded beyond the hit bottom event is rejected as erroneous. CSIRO Code (CSCB) 2 'Act_Code ' 'ACT ' 'HF ' High Frequency Interference. As for spikes, high frequency interference is caused by electrical, or electromagnetic, interference, but results in continual spiking over a wide range of depths. Interference may sometimes appear severe but the temperature records underneath can often be successfully interpolated by filtering. CSIRO Code (CSCB) 126 'Act_Code ' 'ACT ' 'IP ' This history group operates on the complete input record 528 'Act_Code ' 'ACT ' 'IV ' Inversion. Confirmed increase in temperature with depth observed at some point in the profile. Confirmation is established through the observation of the same feature in a neighbouring (usually a repeat) drop. These features usually occur is specific regions. CSIRO Code (CSCB) 99 'Act_Code ' 'ACT ' 'LE ' Leakage. Appears as apparent structure of "jitter" over a range of depths (or the entire profile) that is considered to be unusual as there is little evidence of similar structure in the region, and or there is no confirmation from a neighbouring profile. This flag can be used if there is some element of doubt whether the XBT system is working correctly, i.e., if there is a suspected signal leakage problem with the recording equipment. Leakage can also be a result of insulation penetration which has not healed leading to continuous leakage, or damage to the launcher cable or recorder. CSIRO Code (CSCB) 21 'Act_Code ' 'ACT ' 'NG ' No good trace 4 'Act_Code ' 'ACT ' 'NU ' Inversion in Mixed Layer Confirmed. A nub is a special type of inversion in which an increase of temperature with depth is observed within or at the base of the mixed layer. Confirmation is established through the observation of the same feature in a neighbouring (usually a repeat) drop. CSIRO Code (CSCB) 10 'Act_Code ' 'ACT ' 'PE ' Position error. Profile position has been erroneously encoded. Corrected if possible. 165 'Act_Code ' 'ACT ' 'PI ' Inversion Probable. A probable inversion is defined as an increase in temperature with depth observed at some point in the profile, but which is not fully confirmed by a repeat or neighbouring drop. The feature is considered to be probably real as inversions are known to occur in the region or similar features are found in neighbouring drops. CSIRO Code (CSCB) 632 'Act_Code ' 'ACT ' 'QC ' Quality Control 171 'Act_Code ' 'ACT ' 'RE ' Repeat Drop. Is defined as an XBT deployed within 15 minutes of another one due to suspected previous probe malfunctions, desire to confirm a suspected real feature, or high density sampling. CSIRO Code (CSCB) 1 'Act_Code ' 'ACT ' 'SA ' Surface Anomaly. The surface anomaly is a special case of fine structure that is limited to the top 20 metres of the water column. A warm surface layer can sometimes form from solar heating and light winds (often referred to as the afternoon effect). The afternoon effect can warm surface layers of between 2-10 m thick by up to 1DegC. Cooler freshwater layers due to precipitation or riveroutflow can also cause a surface anomaly to develop. A surface anomaly is generally larger than 0.2DegC. CSIRO Code (CSCB) 33 'Act_Code ' 'ACT ' 'SP ' Spike. Isolated or intermittent spikes can be the result of external electrical or electromagnetic interference that influences the XBT system"s output. CSIRO Code (CSCB) 51 'Act_Code ' 'ACT ' 'TD ' Temperature Difference, A difference in temperature at depth is observed when compared to neighbouring profiles. The temperature difference can occur over the entire profile but the defining feature is the offset at the bottom of the profile. The feature is probably real as eddies, fronts, or currents are known to occur in the region, although there is no exact confirmation from neighbouring profiles. CSIRO Code (CSCB) 7 'Act_Code ' 'ACT ' 'TO ' Temperature/depth offset. The temperature profile exhibits erroneous temperature/depth offsets compared to neighbouring profiles and/or climatology and/or known characteristics of the region. The offsets can occur.at depth, or over sections of the profile, or over the complete profile (The reason could be instrument drift/sensor failure, encoding error, XBT fall rate error, XBT start-of-descent timing error, etc) 1 'Act_Code ' 'ACT ' 'TP ' Test Probe, and devices are frequently used for testing or calibrating XBT systems. CSIRO Code (CSCB) 592 'Act_Code ' 'ACT ' 'WB ' Wire Break. The XBT wire breaks, a short circuit causes the temperature readings to go off scale either to the low (wire breaks from the spool in the launcher) or to the high (wire breaks from the descending probe"s spool) temperature end of the scale. The main cause of wire breaks can be fouling or if the terminal depth of the probe is reached. Often a wire stretch will precede a wire break. CSIRO Code (CSCB) 19 'Act_Code ' 'ACT ' 'WS ' Wire Stretch. A true wire stretch causes an abnormal increase of temperature with depth (usually > 0.2DegC observed over a large range of depths). A wire stretch because of an increase in tension in the wire (due to poor unreeling) can result in a similar bulge to the high temperature side of an XBT profile. These malfunctions can look very similar to temperature inversions, and must be confirmed by a check between neighbouring profiles (usually repeat drops), or have been observed in an area where inversions are known to occur, and flagged as real. Unconfirmed features are flagged according to the degree of confidence. If the anomaly is suspected to be erroneous it should be flagged as a wire stretch. See the CSIRO Quality Control Cookbook for further clarification.
