DATA & METADATA

General overview.

All the data deposited with the IRIS DMC to date.
Data openly accessible as of right now.

MERMAID's International Federation of Digital Seismograph Networks FDSN code is MH.
Seismic data are in SEED format and available from the IRIS Data Management Center.

Access to data from floats P0008, P0010, and P0016 is unrestricted.

Access to other floats is temporarily restricted following standard IRIS and NSF policy. See below for authentication.

MERMAID automatically reports triggered seismograms (time series of acoustic pressure),
but requests can be made for data continuously recorded on its one-year rolling buffer.

If you are interested in making such a data request, contact Joel D. Simon.

For the example of MERMAID P0006, queries returning the station information in StationXML, the GeoCSV positional information, the instrument response plot, and the instrument response in SACPZ and in RESP formats.

Access to data from floats P0008, P0010, and P0016 is unrestricted.

Restricted data are managed by three pieces of information:

  1. The experiment network password is used to verify that a user requesting access to the experiment should be given access. This password is passed from the PIs to users who should be allowed access. Contact Joel D. Simon.
  2. The web-authentication password allows users access to data via Web Services for experiments that they are permitted to view. It is directly coupled with an email address.
  3. The ssl-encryption password allows users to unscramble breq_fast requests to restricted experiments. This password is also coupled to user's email addresses.
If you have the   experiment network password, you can register for data access  here.
