Nitrate/Chlorophyll:
Nitrate concentrations are approximately 2 uM. Seawater
fluorescence is being recorded continuously. Surface seawater
samples are being collected every 4 hours for discrete chlorophyll analysis.
Atmospheric Measurements:
DMS:
SO2:
NH3:
Using oxalic acid coated filters.
CO:

Nitrogen oxides and PAN:
Radon:
CO2:
Solar Radiation:
Aerosol physics:
Aerosol chemistry:
2-stage and 7-stage impactors currently sampling for time
periods ranging from 24 to 72 hours for IC, total organic carbon, speciated
organics, and gravimetric analysis.
Aerosol optical properties:

ISS Status and Schedule:
Sondes were launched every 3 hours yesterday to
support Lagrangian operations. The 4/day schedule has now resumed.
Routine Weather Observations: Going well.
Satellite Observations: None
CTD Cast Schedule: None
SPECIAL PLANNED OBSERVATIONS (NEXT 24-HOURS):
PAST 24-HR OPERATIONS SUMMARY:
Four smart balloons and one ozonesonde were launched yesterday. At the
end of the launches, the ship followed the balloons, stopping every 3 hours
to turn into the wind and sample the physical and optical properties of the
aerosol.
