All French scientists can request the use of these instruments: priority is given to experiments that are highest rated the "geophysics" research ship committee. For projects that do not pass through this committee, an "OBS committee" of scientists from several outside institutions make the selection.
We will provide data to the PI less than one month after the end of the mission, in "SDS" (SeisComp Dataq Structure) format, which is based on daily miniSEED files. We will also provide metadata (positions, instrument responses) in StationXML format (or Dataless SEED, RESP or SAC pole-zero on request).
For active seismic experiments, we will also provide SEGY files, as long as the PI provides us with shot information in a format specified on this website. We will also provide software that the PI can use to extract SEGY files from the continuous SDS dataset.
We will transmit the data to a seismological archiving center. This allows effecient data backup and quality control. After an embargo period of at most 3 years after delivery of data to the PI, the data will be released in the public domain.
For those who do are not used to the miniSEED format, we can provide software to translate the data to other standard formats (SAC, SEISAN, ASCII...), and we can provide instrument positions and responses in text format (SAC pole-zero or GSE2 format for the instrument responses).
