Narrative:
The approach controller pointed out a survey flight; aircraft Y; that was transiting from west to east at 2000 feet. The approach controller switched aircraft X to tower; at 2000 feet inbound from southeast turning straight towards aircraft Y with 200 feet difference and they did not have aircraft Y in sight. I issued traffic again and pilot replied he had him on TCAS. I instructed aircraft X to descend to 1500 feet for traffic; pilot then reported aircraft Y in sight. Aircraft X passed underneath aircraft Y approximately 200 to 300 feet.recommend survey operations be during night shifts when there is less traffic. Approach control should have issued traffic before switching control to tower.
