Title: Measurement of ocean surface biogeochemical parameters for global carbon cycle research
1Measurement of ocean surface biogeochemical
parameters for global carbon cycle research
- Ocean surface pCO2 (CO2 partial pressure)
- estimation of ocean CO2 flux (or sink) from
difference of atmosphere-ocean pCO2 - global ocean carbon cycle model evaluation from
global oceanic pCO2 map with seasonal or monthly
resolution - CO2 related parameters
- nutrients (N, P, Si) as controlling factors of
biological carbon pump - inorganic carbon and alkalinity as carbon
standing stock - chlorophyll and phytoplankton pigments as
indicator of biological standing stock and
species information
2Monthly resolution, how?
- Commercial cargo ship as VOS (volunteer
observation ship) - Four to Six week interval service for Pacific and
Atlantic - Water intake line installation in the ship for
biogeochemical parameter measurement
- NIES monitoring network
- US/Canada-Japan line
- Australia-Japan
- pCO2 continuous measurement and water sampling
for biogeochmical parameters - surface temperature and salinity measurement as
biproducts

5Data Integration of Pacific Data
- IJCD (Inventory of Japanese Chemical
Oceanographic Data) - combining all the observed ocean CO2 data set
PICNIC (PICES CO2 Data Integration for North
Pacific) combining pacific ocean CO2 data set of
US,Canada and Japan
Joint activity by NIES, JMA, JAMSTEC,
JHD Fishery Agency, AIST, and Universities
6US-Japan collaboration for VOS program
- Proposal for starting US-Australia line pCO2
measurement by US side (NOAA/PMEL) - Collaboration in sample analysis of US-Japan VOS
measurement (SIO Scripps Oceanographic
Institution) - PICNIC Pacific ocean CO2 data integration
(PICES Intergovernmental Organization for North
Pacific Ocean Science, working group chaired by
Y.Nojiri/NIES and A.Dickson/SIO) - Global data integration (UNESCO/IOC CO2 Advisory
Panel activity, chaired by D.Wallace, Germany),
relating EU VOS and autonomous CO2 buoy programs
(USA and EU)
7JCOMM SOT meeting
- JOINT WMO/IOC Technical Commission for
Oceanography and Marine Meteorology (JCOMM) Ship
Observations Team, first session, Goa, India, 25
Feb. to 2 Mar. 2002 - Session New types of observations from VOS,
The team will be presented with a report by the
IOC/SCOR CO2 Panel and reports on current
activities relating to biogeochemical
observations from VOS. Based on the reports and
requirements for these observations, the team
will consider the possibilities of operational
observations of such new types of elements using
VOS.
