Projects to observe the marine biota are developed worldwide to mitigate the impacts of anthropogenic noise on marine mammals. The first chapter of this dissertation analyzes guides published by various institutions to orient the methodology to be applied in those projects, in order to ensure better efficacy in mitigating and quality of acquired data. Therefore bibliographic research was made on the internet and it was found 16 guides specific to monitoring cetaceans. The protocols were similar in methodology and mitigation measures suggested. The second chapter analyzed a set of forms utilized during daytime visual observations aboard of drilling rigs occurred in the Sergipe Basin between 2010 and 2012. The objective of the analysis was to evaluate the methodology applied in the project of sighting of marine mammals during oil and gas drilling since the guide applied has been customized from protocols to mitigate the impact of marine seismic surveys. It was proposed indicators of quality based in the content of fields of the forms. The results indicate that the data have good quality to be used in scientific studies of occurrence, distribution and abundance of cetaceans. However, the method used in the monitoring of cetaceans conducted in offshore drilling activities proved ineffective for the purposes of assessing the impacts of oil and gas drilling phase on this group of animals since that the method adopted does not emphasize the behavior exhibited by cetaceans and use forms generalized to four different vertebrate groups.
