  abstract = {{F}ine-grained sediments supplied to the {O}cean by the {A}mazon {R}iver and their transport under the influence of continental and oceanic forcing drives the geomorphic change along the 1500 km-long coast northward to the {O}rinoco {R}iver delta. {T}he aim of this study is to give an encompassing view of the sediment dynamics in the shallow coastal waters from the {A}mazon {R}iver mouth to the {C}apes region (northern part of the {A}mapa region of {B}razil and eastern part of {F}rench {G}uiana), where large mud banks are formed. {M}ud banks are the overarching features in the dynamics of the {A}mazon-{O}rinoco coast. {T}hey start migrating northward in the {C}apes region. {S}uspended {P}articulate {M}atter ({SPM}) concentrations were calculated from satellite products ({MODIS} {A}qua and {T}erra) acquired over the period 2000-2013. {T}he {C}ensus-{X}11 decomposition method used to discriminate short-term, seasonal and long-term time components of the {SPM} variability has rendered possible a robust analysis of the impact of continental and oceanic forcing. {C}ontinental forcing agents considered are the {A}mazon {R}iver water discharge, {SPM} concentration and sediment discharge. {O}ceanic forcing comprises modelled data of wind speed and direction, wave height and direction, and currents. {A} 150 km-long area of accretion is detected at {C}abo {N}orte that may be linked with a reported increase in the river's sediment discharge concurrent with the satellite data study period. {W}e also assess the rate of mud bank migration north of {C}abo {N}orte, and highlight its variability. {A}lthough we confirm a 2 km y(-1) migration rate, in agreement with other authors, we show that this velocity may be up to 5 km y(-1) along the {C}abo {O}range region, and we highlight the effect of water discharge by major rivers debouching on this coastal mud belt in modulating such rates. {F}inally, we propose a refined sediment transport pattern map of the region based on our results and of previous studies in the area such as the {AMASSEDS} programme, and discuss the relationship between sediment transport and accumulation patterns and the coastal geomorphology of this region.},
