6 -9 April
10 April
Ship loading at 0900 hrs
Depart from Snug harbor at 0900 hrs. Science personnel on-board by 0800.

Station ALOHA operations.
Arrive back to Snug Harbor.
4.0 OPERATIONAL PLAN
4.1.
Station ALOHA (22°45'N, 158°W with 6 nm radius)
4.1.1. PIT Sediment trap array deployment RF Ch. 68, 157.425 MHz
Upon arrival to Station ALOHA, a floating sediment traps array will be deployed at a location
within Station ALOHA, to be determined en route to ALOHA by local current conditions. The
sediment trap array will be deployed from the stern, using the A-frame and large Sea-Mac
winch. Power requirement for the winch is 440 VAC, three phase at 10 amps. After deployment
we request that the bridge verify that the radio transmitters are functioning and directionally
correct. The PIT sediment trap array will be equipped with 2 ARGOS satellite transmitters
(platform #’s 3028, 60482), 2 strobe lights, and radio transmitters (RF Ch. 68, 157.425 MHz) and
will consist of 3 crosses 2 @150m and 1 @ another depth TBD. Daily positions of the array shall
be transmitted by email directly to the ship ([email protected], password: argosfix),
therefore the ship will not need to keep within sight of the array until the time of the recovery.
Assistance from the bridge is requested in plotting the drift track of the array. We request the
use of the ship's radio direction finder for locating the array before recovery.
NOTE: depending on the speed and distance this array travels, the time for recovery may shift to
maximize time for operations at Station ALOHA.
4.1.2.
Deployment of two McLane bottom-moored sediment traps in the vicinity of 22°51'N, 157°54W.
Two conical McLane sediment traps @ 4000m, glass floats and a mooring weight will be
deployed from the stern using the A-frame and large Sea –Mac winch (see attached diagram 1.)
Power requirement for the winch is 440 VAC, three phase at 10 amps. After deployment we
would like to triangulate the position of the deep-moored sediment traps.
4.1.3. On the first day at Station ALOHA (4/7), CTD casts will recommence.
4.1.4. Water column measurements
Vertical profiles of temperature, conductivity and dissolved oxygen will be made with the OTG
instrument package consisting of a Sea-Bird CTD attached to a 24-place rosette with 12 liter
Bullister sampling bottles. We will need the ship’s CTD winch and A-frame for these operations.
Water samples for biogeochemical measurements will be collected on each cast. There will be
an additional instrument to be included with the OTG CTD package –two Transmissometers with
a pump. Power requirement is 35-50 mA at 7-15V.
4.1.5. Primary Production Array deployment
A free drifting incubation array will be deployed once during this cruise, for 12- hour duration,
starting on the second day (4/7) of the cruise at Station ALOHA. We request the use of the Aframe for this operation and will also use the Sea-Mac winch. The array is equipped with two
ARGOS satellite transmitters (platform #’s 84857,60484) a strobe light and a radio transmitter
(RF Ch. 74, 157.725 MHz). Positions of the array shall be transmitted by email directly to the ship
([email protected], password: argosfix).
4.1.6. Hyperpro
The Hyperpro is a profiling unit with one up-looking and one down-looking hyperspectral
radiometer, a WET Labs ECO-BB2F triplet (measuring Chlorophyll-a fluorescence and
backscattering in the blue and red wavelengths), temperature and conductivity sensors. This
instrument also incorporates a ship mounted surface radiometer. The Hyperpro will be deployed
daily during the cruise. The Hyperpro is deployed from the stern through a small block hung
from the A-frame. The instrument is hand-lowered and retrieved. Each deployment will consist
of three profiles before the instrument is retrieved and take approximately 45 min to complete.
4.2
Acoustic Doppler Current Profiler
The ship’s acoustic Doppler current profiler (ADCP) will be in operation during the duration of
the cruise. The OTG electronics technicians will be in charge of the ADCP system.
Thermosalinograph, pCO2 system, Fluorometer, and meteorological system
4.3
The ship’s thermosalinograph, pCO2 system and fluorometer sampling the uncontaminated
seawater supply system will be in operation during the duration of the cruise while the ship is
outside of Snug Harbor. The ship’s meteorological system shall be in operation throughout the
cruise. Access to real-time underway data through the ship’s network will be required. The OTG
technicians will be in charge of the thermosalinograph, pCO2 system, Fluorometer, and
meteorological suite operations.
Whenever pumping of the ship’s tanks is needed, it must be conducted outside the circle that defines
station ALOHA (Sect. 1.0). To avoid disruptions in the schedule, this operation should be coordinated
with the chief scientist and co-chief scientist.
