@article{fdi:010007558, title = {{S}easonal variations of sea-surface salinity and temperature in the tropical {I}ndian {O}cean}, author = {{D}onguy, {J}ean-{R}en{\'e} and {M}eyers, {G}.}, editor = {}, language = {{ENG}}, abstract = {{M}easurements of sea-surface temperature and sea-surface salinity obtained from ships-of-opportunity are used to map the fields in the tropical {I}ndian {O}cean. {T}he seasonal variation is described in detail along the six shipping tracks that have the best data coverage : {G}ulf of {A}den to {L}a {R}eunion island, {P}ersian {G}ulf to {C}ape {T}own, {G}ulf of {A}den to east {A}frica, {G}ulf of {A}den to {I}ndonesia, {S}ri {L}anka to {T}orres {S}trait through {M}alacca {S}trait, and along the west coast of {A}ustralia. {S}easonal variation with large amplitude is found in an extensive area in the western {I}ndian {O}cean. {I}n the eastern {I}ndian {O}cean, seasonal variation is small, except where it is linked to local features such as coastal upwelling, local wind or rainfall-runoff. {W}ater masses, defined from the surface {T}-{S} diagram, are related to winds and currents or are formed locally. {T}he movement of these water masses is linked to currents driven by the monsoon circulation.
