a.sorption a.d fluorescence properties of chromophoric dissolved orga.ic ma.ter （CDOM） a.ong a.124 km tra.sect in the Ba.a.a.ia.Ba.in, a.la.ge estua.y loca.ed in Louisia.a. usa, were investiga.ed during high a.d low flow periods of the Mississippi River in the spring a.d winter of 2008-2009. Mea. CDOM a.sorption a. 355 nm from the ma.ine to the freshwa.er end member sta.ions ra.ged from （3.25 ± 0.56） to （20.76 ± 2.43） m^-1 for the three month high flow period wherea. it va.ied from （1.48 ± 1.08） to （25.45 ± 7.03） m^-1 for the same sta.ions during low flow period. Corresponding salinity va.ues a. these sta.ions indica.ed the influence of river a.d shelf excha.ges in the lower ba.in a.d precipita.ion a.d runoff in the upper ba.in. a. inverse rela.ionship of CDOM a.sorba.ce a.d fluorescence with salinity observed in the ba.in could he a.useful indica.or of salinity. CDOM fluorescence a.so va.ied over a.la.ge ra.ge showing a. a.proxima.ely 8 to 12-fold increa.e between the ma.ine a.d freshwa.er end members for the two flow sea.ons. Excita.ion-emission ma.rix spectra. plots indica.ed the presence of va.ious fluorescence components with highest being the a.pea., lowest the T-pea., a.d the C a.d M-pea.s showing simila. trends a.ong the tra.sect. During low flow sea.on the a.C ra.io were well correla.ed with sta.ion loca.ions indica.ing increa.ed terrestria. influence towa.ds the upper ba.in. CDOM a.sorption a.d fluorescence a. 355 nm were highly correla.ed a.d independent of CDOM sources suggesting tha. fluorescence could be used to cha.a.terize CDOM in the ba.in.
