The first-passage time distribution function is used to determine in a probabilistic sense when and where a fluid element will make its first contact with the surface as a function of its position in the ocean interior. The last-passage time distribution is used to determine when and where a fluid element made its last contact with the surface. A computationally efficient method is presented for recursively computing the first few moments of the first- and last-passage time distributions by directly inverting the forward and adjoint transport operator. This approach allows integrated transport information to be obtained directly from the differential form of the transport operator without the need to perform lengthy multitracer time integration of the transport equations. The method, which relies on the stationarity of the transport operator, is applied to the time-averaged transport operator obtained from a three-dimensional global ocean simulation performed with an OGCM. With this approach, the author (i) computes surface maps showing the fraction of the total ocean volume per unit area that ventilates at each point on the surface of the ocean, (ii) partitions interior water masses based on their formation region at the surface, and (iii) computes the three-dimensional spatial distribution of the mean and standard deviation of the age distribution of water.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">ISI:000228835400009</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;ISI Document Delivery No.: 922JYTimes Cited: 21Cited Reference Count: 30Cited References:      AMESTOY PR, 2001, SIAM J MATRIX ANAL A, V23, P15     BROECKER WS, 1982, TRACERS SEA     BROECKER WS, 1991, GLOBAL BIOGEOCHEM CY, V5, P87     BROECKER WS, 1998, J GEOPHYS RES-OCEANS, V103, P15833     CALDEIRA K, 2001, 1 NAT C CARB SEQ WAS     DELEERSNIJDER E, 2001, J MARINE SYST, V28, P229     DELHEZ EJM, 2002, J MARINE SYST, V31, P279     ENGLAND MH, 1995, J PHYS OCEANOGR, V25, P2756     GENT PR, 1990, J PHYS OCEANOGR, V20, P150     GOODMAN PJ, 1998, J PHYS OCEANOGR, V28, P1759     GURNEY K, 2000, 707 COL STAT U DEP A     HAINE TWN, 2002, J PHYS OCEANOGR, V32, P1932     HALL TM, 1994, J GEOPHYS RES-ATMOSP, V99, P1059     HALL TM, 2002, GLOBAL BIOGEOCHEM CY, V16, ARTN 1131     HALL TM, 2002, J PHYS OCEANOGR, V32, P1987     HALL TM, 2004, GLOBAL BIOGEOCHEM CY, V18, P1031, DOI     10.1029/2003GB002120     HOLZER M, 2000, J ATMOS SCI, V57, P3539     JENKINS WJ, 1998, J GEOPHYS RES-OCEANS, V103, P15817     KHATIWALA S, 2001, DEEP-SEA RES PT I, V48, P1423     LARGE WG, 1994, REV GEOPHYS, V32, P363     QIU B, 1995, J PHYS OCEANOGR, V25, P2374     REDNER S, 2001, GUIDE 1 PASSAGE PROC     SIDJE RB, 1998, ACM T MATH SOFTWARE, V24, P130     SIGMAN DM, 2000, NATURE, V407, P859     STOMMEL H, 1960, DEEP-SEA RES, V6, P140     STRATONOVICH RL, 1963, TOPICS THEORY RANDOM, V1     THOMAS H, 2001, GEOPHYS RES LETT, V28, P547     WAUGH DW, 2002, REV GEOPHYS, V40, ARTN 1010     WAUGH DW, 2003, J GEOPHYS RES-OCEANS, V108, ARTN 3138     WUNSCH C, 2002, J GEOPHYS RES-OCEANS, V107, ARTN 3048Amer meteorological socBoston&lt;/p&gt;</style></notes><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;Univ Calif Irvine, Dept Earth Syst Sci, Irvine, CA 92602 USA.Primeau, F, Univ Calif Irvine, Dept Earth Syst Sci, Croul Hall, Irvine, CA 92602 USA.fprimeau@uci.edu&lt;/p&gt;</style></auth-address></record></records></xml>
