Abstract

There were 501 sightings of marine mammals (13,398 individuals) during seismic surveys in UK waters and some adjacent areas in 1999. 14,341 hrs 19 mins were spent watching for marine mammals during seismic surveys.

No significant effects of seismic activity were observed for site surveys, but sample sizes were low, precluding allowance for potential sources of bias such as weather conditions. Revised standard recording forms are proposed in line with comments and suggestions received. A number of items are included for consideration when the Guidelines for minimising acoustic disturbance to marine mammals from seismic surveys are next revised.
