When the data acquisition (DAQ) system of an underwater neutrino telescope is interfaced with IBAS and GCN, all raw data can be saved to disk for a few minutes when a GRB alert message is received. If the DAQ system is designed such that it constantly buffers a few minutes of raw data, the data that were taken before the alert could then also be saved to disk. Consequently all raw data covering a few burst durations before and after the burst will be available. Any time-correlated neutrino signal will thus be included in these data. The data can be analysed offline using the known position of the GRB. Using the time and direction information of GRBs, the detection threshold for the neutrinos they emit could be lowered. The increase in detection efficiency achieved in this way will be quantified for the ANTARES experiment.
