  abstract = {{P}urpose {U}rbanization is a major driver of land use change and can affect the soil organic carbon ({SOC}) pools. {T}his study aimed to understand the urbanization impact on {SOC} stocks and pools at profile scale (0-100 cm). {M}ethods {T}he {SOC} was studied at 0-30 and 0-100 cm depths in park and sealed soils of three {F}rench cities ({M}arseille, {N}ancy, and {N}antes). {P}hysical fractionation was performed to gain insight on the size of different {SOC} pools (particulate and organo-mineral soil fractions). {R}esults {T}he {SOC} stocks were seven to ten times higher in parks than in sealed soils, but lower than in natural soils according to literature data. {T}he contribution of the first 30 cm to profile {SOC} stock was around 40%, with strong heterogeneity, especially in sealed soils. {C}onsidering the whole 0-100 cm profile, {SOC} stocks in particulate organic matter fractions (light fraction > 50 mu m) were 25-48 times higher in parks than in sealed soils, while {SOC} stocks in mineral-associated fractions (< 50 mu m) were only 4-6 times higher in parks than in sealed soils. {A}n unexpectedly high proportion of {SOC} was found in the heavy fraction > 50 mu m, particularly in sealed soils (11% in average at 0-100 cm depth). {T}his fraction associated to sand is usually poor in {SOC} in natural or agricultural soils. {I}n these urban soils, it might be bitumen, a dense organic artifact. {C}onclusion {T}he {SOC} stocks up to 100 cm depth and their heterogeneity pleaded to strengthen and expand {SOC} studies in all urban soils.},
