Abstract

Both L-shaped (“L”) and straight (“Straight”) sample probes have been used to collect water samples from a main ballast line in land-based or shipboard verification testing of ballast water management systems (BWMS). A series of experiments was conducted to quantify and compare the sampling efficiencies of L and Straight sample probes. The findings from this research—that both L and Straight probes sample organisms with similar efficiencies— permit increased flexibility for positioning sample probes aboard ships.
