  abstract = {{A}n {E}arth {S}ystem model with an oceanic biogeochemical component is shown to reproduce accurately the seasonal course of sea-ice and chlorophyll distribution in the {A}rctic region. {I}t is argued that the phytoplankton blooms that occur concomitantly with the ice retreat along the {A}rctic coastal shelves in spring and summer strongly impact the {A}rctic climate and improve the sea-ice distribution in the model. {I}ndeed, these blooms modify the vertical distribution of radiant heating and trap the penetrating solar heat flux at the surface in these regions. {T}he resulting surface warming triggers a reduction of sea-ice thickness and concentration. {T}his reduction increases the solar energy penetrating into the ocean, therefore providing a positive feedback that further amplifies the direct biological warming. {T}he increased melting, precipitation and runoff related to these bio-physical feedbacks freshen the {A}rctic {O}cean and the {G}reenland {S}ea, provoking a slight slowdown of the overturning circulation. {C}itation: {L}engaigne, {M}., {G}. {M}adec, {L}. {B}opp, {C}. {M}enkes, {O}. {A}umont, and {P}. {C}adule (2009), {B}io-physical feedbacks in the {A}rctic {O}cean using an {E}arth system model, {G}eophys. {R}es. {L}ett., 36, {L}21602, doi: 10.1029/2009{GL}040145.},
