The map to the right shows all of the sightings during the 1988-1993 Tampa Bay photographic identification surveys, showing what appears to be a fairly even distribution of sightings through the southeast coastal waters of Tampa Bay, unlike what we have seen in recent surveys. However, we do not have any more recent baseline distribution data than 1993, and we do not know if any changes have occurred between 1993 and 2021.
We do know that at least some of the long-term residents of this dolphin community still use the previously defined community range. Several individuals first identified from as far back as 1984 and the 1990s have been documented in our recent surveys. Quantitative analyses of dolphin distributions and abundance remain to be completed.
So far, no obvious indications of health issues have been observed with dolphins in the vicinity of the discharge.
