The 244 profiles that were received from the ITP appear to be largely free of fouling and instrument errors, and were processed according to the procedures described in the ITP Data Processing Procedures.  The processing parameters (described in ITP Data Processing Procedures) for ITP2 are shown in the figures to the right.  A software bug in the underwater unit resulted in instrument resets during two profiles (107 and 214) so that no information is available from those.  As per design, the instrument successfully resumed operation on the subsequent profiles.  Profiles 188, 208, and 209 had large segments of presumably contaminated conductivity data that were discarded.  A few other conductivity spikes were removed, but the temperature data appeared to be completely uncontaminated.

See the Data Products tab to the left for descriptions of the three levels (I, II, III) of data processing and to access all data.
