Blacknest BDS Public Documentation

This website provides access to the public documentation for the Blacknest BDS system.

The Blacknest Data System (BDS) system consists of a set of Linux server hardware platforms with large disk arrays for storage of seismic sensor data and metadata along with the software system that provides access to the seismic data and associated metadata information. The system stores and manages multiple terabytes of seismic data from very old seismic data sources as well as live streaming import of current data from multiple sources.

The BDS software system provides a core platform that is modular in design and integrates the seismic sensor data with its metadata. The BDS core defines an object orientated newtwork API for data import, storage and export. It also provides data convertors to allow import and export in multiple legacy and new seismic data formats. The basic core system can be extended with additional modules as required.

Development of the BDS system is an on-going process adding features and working around issues in the seismic data and meta data as they arise.
The seismic data is obtained from seismic stations and arrays of stations situated at various places in the world. Each seismic station consists of one or more seismometers detecting earth movement in one or more directions. The low frequency analogue data from each seismometer is digitally sampled, at a low sample rate, and stored as a channel in a data file. There is also an archive of analogue data on tapes which will be digitised for inclusion into the system.
