Published July 1988 through June 1999
FROM VOLUME 3, NUMBER 4, APRIL 1990
"An Assessment of the Transport of Atmospheric CO2 Into the Arctic
Ocean," L.G. Anderson (Dept. Analyt. Marine Chem., Chalmers Univ. Technol.,
S-412 96, Goteborg, Sweden), D. Dyrssen, E.P. Jones, J. Geophys. Res.,
95(C2), 1703-1711, Feb. 15, 1990.
Uses data from the Canadian Expedition to Study the Alpha Ridge Ice Camp,
the Ymer 80 expedition and the 1984 F.S. Polarstern Marginal Ice
Zone Experiment to establish that most of the CO2 goes into the surface mixed
layer and halocine waters. A small flux to the Atlantic layer is discernible,
while no flux to the deep water could be observed.
"Carbon Budget of the Terrestrial Biosphere," G. Esser
(Fachbereich Biol./Chem., Univ. Osnabrueck, D-4500 Osnabrueck, FRG), Verh.-Ges.
Oekol., 18, 387-396, 1988 (publ. 1989). In German.
The carbon pool of the terrestrial biosphere is an important link in the
global carbon cycle. A regionalized, climate-sensitive global carbon balance
model was developed to investigate the effects of forest clearing and
fertilization on the global carbon balance.
"Absorption of Carbon Dioxide by the Ocean as a Function of Its
Concentration in the Atmosphere," V.V. Alekseyev (Moscow Univ.), S.I.
Zaytsev, S.V. Kiseleva, Izvestiya, Atmos. Ocean. Phys., 24(5),
1988 (Eng. Ed. 416-417, Dec. 1988; publ. 1989).
Derives an equation for the solubility of CO2. Concludes that, of the total
amount of anthropogenic CO2 entering the atmosphere, only 58% remains in the
atmosphere while the rest is apparently absorbed by the ocean. Calculates that a
doubling of CO2 would decrease its relative solubility by a factor of 1.4 and
increase the proportion remaining in the earth's atmosphere.
