  abstract = {{O}cean warming can modify the ecophysiology and distribution of marine organisms, and relationships between species, with nonlinear interactions between ecosystem components potentially resulting in trophic amplification. {T}rophic amplification (or attenuation) describe the propagation of a hydroclimatic signal up the food web, causing magnification (or depression) of biomass values along one or more trophic pathways. {W}e have employed 3-{D} coupled physical-biogeochemical models to explore ecosystem responses to climate change with a focus on trophic amplification. {T}he response of phytoplankton and zooplankton to global climate-change projections, carried out with the {IPSL} {E}arth {S}ystem {M}odel by the end of the century, is analysed at global and regional basis, including {E}uropean seas ({NE} {A}tlantic, {B}arents {S}ea, {B}altic {S}ea, {B}lack {S}ea, {B}ay of {B}iscay, {A}driatic {S}ea, {A}egean {S}ea) and the {E}astern {B}oundary {U}pwelling {S}ystem ({B}enguela). {R}esults indicate that globally and in {A}tlantic {M}argin and {N}orth {S}ea, increased ocean stratification causes primary production and zooplankton biomass to decrease in response to a warming climate, whilst in the {B}arents, {B}altic and {B}lack {S}eas, primary production and zooplankton biomass increase. {P}rojected warming characterized by an increase in sea surface temperature of 2.29 +/- 0.05 degrees {C} leads to a reduction in zooplankton and phytoplankton biomasses of 11% and 6%, respectively. {T}his suggests negative amplification of climate driven modifications of trophic level biomass through bottom-up control, leading to a reduced capacity of oceans to regulate climate through the biological carbon pump. {S}imulations suggest negative amplification is the dominant response across 47% of the ocean surface and prevails in the tropical oceans; whilst positive trophic amplification prevails in the {A}rctic and {A}ntarctic oceans. {T}rophic attenuation is projected in temperate seas. {U}ncertainties in ocean plankton projections, associated to the use of single global and regional models, imply the need for caution when extending these considerations into higher trophic levels.},
