  abstract = {{T}he {I}ndonesian {M}ixing ({INDOMIX}) cruise of {J}uly 2010, resolves the {P}acific {O}cean water masses spreading from the {H}almahera {S}ea through the {S}eram {S}ea, {M}anipa {S}trait, {B}anda {S}ea, to the {O}mbai {S}trait, and along the southern margin of {L}esser {S}unda {A}rc across the northern {S}avu {S}ea, {S}umba {S}trait, and south of {L}ombok {S}trait. {T}his paper focuses on the characteristics and stratification of the water masses, along this path and {P}art {II} of this study discusses the biogeochemical aspects. {T}wo companion papers on quantification of turbulent mixing have been published elsewhere. {W}e find: a) {A} marked transformation of {S}outh {P}acific ({SP}) thermocline water within a sharp salinity front between the {H}almahera {S}eram {S}eas. {T}idally induced vertical mixing is the main process weakening the {SP} stratification, as suggested by a simple 1-dimensional diffusion model forced by vertical diffusivity of {INDOMIX} vertical microstructure profiler dataset. {T}he transformation of {SP} water by vertical mixing can occur after 3 days, which is in good agreement with previously reported water mass residence times. {L}ateral advection plays a minor role; b) {I}nterleaving salinity structure within the thermocline of the central {H}almahera {S}ea and two deeper inflow channels. {T}he interleaving salinity features within the central {H}almahera {S}ea thermocline occurs where vertical diffusivity is relatively weak, compared to the vertical mixing at entry/exit portal that removes the interleaving salinity features. {T}wo deeper inflow channels (about 950 m and 740 m depth) in the entry portal of the {H}almahera {S}ea are mapped from the multi-beam echo sounder measurement, where both channels allow the renewal of {SP} thermocline water and salinity interleaving processes; c) {N}orthward flow of thermocline water (100-200 m depth) in the {M}anipa {S}trait that injects {B}anda homogeneous salinity water into {S}eram {S}ea that erode {H}almahera salty water via strong diapycnal mixing; d) {C}yclonic upper layer circulation in {B}anda where eastward (westward) flow occurs in the northern (southern) {B}anda, confirmed by recent modeling study; and e) {R}elative salty {I}ndian {O}cean intermediate water flowing along southern margin of the {L}esser {S}unda {A}rc, within the {S}outh {J}ava {U}ndercurrent. {T}wo distinct upper thermocline water, due to different source of {I}ndonesian {T}hroughflow ({ITF}) water, are found in the {B}anda {S}ea: fresher and colder water contrasting to saltier and warmer water that converge in this confluence region. {B}eneath it, {B}anda intermediate homogeneous salinity water and low dis -solved oxygen water is dominant.},
