Islip Hatchery SeaCat Results
    One station is at a shellfish hatchery in Islip.  A casing is set up in the pump room to hold a SeaCat.  Water is pumped into the casing from the bottom and then the excess is bled out at the top of the casing.  The water that is pumped in comes from about twenty yards offshore just above the bottom.  The instrument does not have many problems with biofouling, unlike the other stations, but it has encountered an unforeseen problem that can be seen in the March 2007 - May 2007 figure below.   Because the water that is pumped in comes from the bottom of the bay, sediment is taken up as well.  Once inside the casing, the sediment accumulates.  Due to the original orientation of the SeaCat, this sediment clogged the conductivity cell, causing issues with the salinity curve.  The orientation has been corrected and possible solutions are being looked into.
    Starting in June 2008, the SeaCat station was moved outside the hatchery to a small pier nearby.  The water depth there is very shallow, causing the conductivity cell to become dry during some low tides in the June - September 2008 record.  The instrument has since been reoriented to solve the problem.
   The SeaCat was removed from the fishing pier in February 2009 because that location was too vulnerable to ice.  It has since been relocated to the outer most water intake piling for the Islip Hatchery.  This new location is about 200m west of the fish pier and adjacent to the hatchery itself.
