  abstract = {{T}he stable oxygen isotopes ratio (518{O}) from marine mollusk carbonated shells is widely used as a palaeothermometer, as the main driver of this ratio is the temperature (coupled with the salinity) at which the carbonate precipitated. {T}his method is also used on anthropogenic shell middens, as a proxy for past human practices and their use of marine resources: the {S}ea-{S}urface {T}emperature reconstructed from the shell margin can be interpreted as the season during which the people who produced the midden collected the shells. {T}o better understand the occupation patterns and protohistoric practices of shellfish collection in the {I}roise {S}ea and the {M}ol{\`e}ne archipelago ({F}inist{\`e}re, {F}rance), we analyzed seasonality data of limpets ({P}atella sp.) from {L}ate {N}eolithic ({LN}, 2570 - 2140 cal. {BCE}), {E}arly {B}ronze {A}ge ({EBA}, 2140 - 1740 cal. {BCE}) and {E}arly {M}iddle {A}ge ({EMA}, 620 - 820 cal. {CE}) occupations within shell middens of two islands: {M}ol{\`e}ne and {B}{\'e}niguet. {T}he methodology allowed us to discriminate seasonal and permanent occupations for {B}{\'e}niguet {I}sland site, enriching archaeological observations. {O}ur results also show that the largest shell middens yield all year round collection, on both islands, confirming the continuous occupation of these territories, despite uneven intensity of collection throughout the year. {T}he most represented seasons are late winter and spring, both on {B}{\'e}niguet and {M}ol{\`e}ne islands, and for {LN} and {EBA} suggesting an intensification of collection to compensate resource depletion toward the end of winter. {T}hese results complete and enhance the previous seasonality data existing on these sites demonstrating here that not only the number of analyzed shells but also their spatial distribution within the midden can impact the seasonality interpretation. {T}his approach now needs to be completed by the determination of seasonality indicators on the other resources present in the middens, to truly grasp the domestic economies of these past insular populations.},
