SB Student Intern Graham Kelly Launches Zooplankton Pump Sampler

ISEA's high school intern Graham Kelly initiated the first test of his zooplankton pump sampler at the ISEA schooner dock today.  The sampler consists of a submersible Rule bilge pump, hose, 153 micron plankton net, and car battery.  This first test will run overnight to determine the effectiveness of this method on night-active zooplankton (knowing that the numbers and species diversity is limited at this time of year).   Graham and his dad will return to the dock tomorrow to collect the sample. 

An earlier test showed that copepods can pass through the device intact.
