  abstract = {{T}he distribution of planktonic foraminifera in box-core tops under the influence of a western boundary upwelling system along the southeastern {B}razilian continental margin was examined to evaluate the similarity percentage ({SIMPER}) and to create a biofacies model for paleoenvironmental applications. {S}pecies associated with warm and oligotrophic water were distributed in the {R}io de {J}aneiro sector of the {C}ampos {B}asin, while productive water species were most abundant in the {R}io de {J}aneiro sector of the {S}antos {B}asin, and cold-water species were most abundant in the {C}abo {F}rio {U}pwelling {S}ystem ({CFUS}). {F}our major biofacies are associated with the oceanographic setting of the" {CFUS}: one from the {C}ampos {B}asin ({A} {B}razil {C}urrent front), one from the {S}antos {B}asin ({B} mixture of coastal and oceanic waters), and two associated with the {C}abo {F}rio {H}igh in the northern biofacies ({C}) and southern biofacies ({D}). {T}he distribution of biofacies {C} and {D} was associated with temperature differences. {B}iofacies {C} represents a mixture of upwelling and tropical waters, while biofacies {D} represents a mixture of cold, nutrient-rich and {S}antos {B}asin waters. {T}hese biofacies were also defined in core {CF}10-01{B}, in which six main paleoceanographic phases were characterized during the last 9 cal kyr, predominantly showing alternating dominance between biofacies {C} and {D}. {F}rom 9.0 to 5.0 cal kyr before the present ({BP}), the system was dominated by biofacies {C}. {B}etween 4.0 and 3.5 cal kyr {BP}, biofacies {D} was dominant. {B}etween 3.5 and 2.5 cal kyr {BP}, a strong influence of coastal waters and weakened upwelling activity were indicated by the dominance of biofacies {B} + {C} + {D}. {T}he last 2.5 cal kyr was dominated by biofacies {D}. {T}he {SST} in this core was reconstructed using the {M}odern {A}nalog {T}echnique ({MAT}), which revealed 0.35 {C} of variability, indicating no {SST} changes during the {H}olocene. {T}he weak sensitivity of the {MAT} was due to the interplay among different oceanographic features.},
