We attempted to figure out location and timing information of the dolphin sightings collected from two major social media, Naver Café and Instagram. 142 of dolphin sighting information were derived from 2,501 dolphin related postings on Naver Café between 2004 to informative postings also were found on Instagram through hashtag searching. The number of posts about dolphin sighting was not frequent until Since 13 posts were found in 2014, dramatic increase of the sighting numbers was accelerated as 38 in 2015, 93 in 2016 and 269 in (45.7%) from coastal area of Daejeong-eup, south-western part of the Island, were posted. The number of dolphin sightings also high from Gujwa-eup(n=50, 11.7%), Hangyeong-myeon (n=49, 11.5%), Seongsan-eup (n=38, 8.9%) and Seogwipo-si (n=34, 8.0%). Our results show that social media data has a high potential to be used as a data source for study of distribution pattern of the dolphins.
