-10The flfth proJect ls !o obtaln better lnforuatlon on Bhe traascarbon dloxlde froo surface lraters Lnto the deeper ocean. Thls would lnvolve uot ooly studies of C02 but also of tracers 6uch as trltium, he1fi:o-3 and radlocarboa. Thls would tequlre teEearch wlth oceanographlc shlps and, when conpletely under way, would cost about $5 W/year. The last of the hlgh prlorlty programs fo! 1@edlate fuudlng is to obtaln better lnforEetlon on the buffering of C02 absorptlon Ln the ocean. fer of After the 1nlt1al ptoglaDs are uoder !ray, the Advlsory CoeElttee 1s recmendlng that an addltlonal effort Lovolvlug seven Dore proglao6 be establlshed. These are l1sted, tn order of prlorlty, ln Vugraph 17. The ent1re proglao nouLd cost 91.26 loi l.tr th€ plaonl.ng phase and would rlse to $5 MM/year when under !ray. The flrst ltem 1n thls prograD, and the aeventh ln the overall prlorlty list, 1s to deternlne lrhether shallos lrate! calbonates are dlssolvlug because of C02 1evels. The secoad lteE rrould be to obtaln a better estlDate of the lesponse of the blota as a slok for addltlonel carbon dloxlde. The thlrd ln thls program is to develop better models fo! the carbon cycle. Although nodellng is en extreDely tmportant undertaklng, 1t 1s pleced n1trth on the overall 1lst because lnforDatlon flon the earller pro8lans ls needed for bette! nodel developuent.

V. Suppary A euuoary of rny talk 1s presented ln Vugraph 18. In the filst place' there 1s geoeral eclentlflc agreement that the Eost 1lkely nanner ln whlch oaukiad ia lnfluetrclng the global cllsate ls through earbon dloxlde release floa the buralag of fossll fuels. A doubllng of earbon dloxlde 16 egtlaated to be eapable of lacreaslng the average global tenperature by fron 10 to 3oC, wlth a 10"C rlse predlcted at the poles. More research i.B needed, howeve!, to estab116h the va11d1ty and signiflcance of predlctlons wlth respect to the Greeahouse Effect.
