| A daylight
incubation area on the forecastle (O2 level, near
the rail) provide nearly unobstructed sunlight
and auxiliary/uncontaminated seawater for temperature
control. This area has the best sunlight exposure
on the vessel while providing running seawater
and minimizing distance from the sampling/laboratory
areas.

This area is capable of holding any of the following:
tray incubator (approximate size 4'x6'x12")
screened boxes (between 5 and 7 total; approximate
size 4’x6’x12")
large volume tubs/trays (approximate size 2’x4’x18")
tub/tray may be secured directly to deck using sockets
provided.
Other incubation areas without sunlight could be
located on the O2 level (Port Side) adjacent to
the helicopter hangar. In addition, an area (12'
X 8') just forward of the helicopter control station
and aft of the stacks (O4 level) has been outfitted
with auxiliary seawater. While this area provides
adequate sunlight, due to its proximity to the machinery
stacks, this area may be several degrees above ambient
temperature.
Scientists should note that none of these areas
affords 100% obstruction-free direct sunlight exposure.
Also, HEALY currently has limited capability to
provide ambient sea water to locations needed, especially
when operating in the the ice. Incubation arrangements
must be addressed in the cruise planning process.
