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.
