Overview

Petroleum Geo-Systems (PGS) provided marine blended source acquisition data for the IEEE signal processing competition in Tokyo (2017). The data in consists oe a 2768x256x256 (ntime, nreceiver, nshot) data matrix and the time delay between consecutive shots. The data has 4 ms sample rate and is in Matlab format. No geometry information is available. There is a Jupyter notebook with Python to read the data. A link to a PGS paper describing one method to deb lend marine seismic data is at this link

Data includes: Matlab data array of dimension 2768x256x256 (ntime, nreceiver, nshot) data matrix. Matlab data array of dimension 256x256 (nreceiver,nshot) of the time delay between consecutive shots of size 256x256 (nreceiver, nshot). Two pdf files that briefly describes the data and rules for the 2017 IEEE single processing competition. Jupyter notebook with Python that reads the matlab format data into numpy arrays.
