  abstract = {{T}he timing of neoglacial advances in the {A}ntarctic {P}eninsula ({AP}) is not yet well constrained. {A}ccurate temporal reconstruction of {N}eoglaciation in the {AP} is needed to better understand past glacial responses and regional and global teleconnections during the {H}olocene. {H}ere, we examine all available information about neoglacial advances in the {S}outh {S}hetland {I}slands ({SSI}) as well as in the broader geographical context of the {AP} region and {A}ntarctic continent. {I}n order to shed light on the contrasting chronologies existing for neoglacial advances in these regions, we focused on a case study where a detailed picture of the {H}olocene deglaciation was already available. {L}ake sediments revealed that {B}yers {P}eninsula, west of {L}ivingston {I}sland ({SSI}), was fully deglaciated during the {H}olocene {T}hermal {M}aximum. {T}o complement this approach, we identified glacially polished bedrock surfaces, erratic boulders and a moraine ridge near the present front of the glacier in the {SE} corner. {W}e applied cosmogenic ray exposure ({CRE}) dating using in situ {C}l-36 for basalt rocks and {B}e-10 for granitic rocks in: (i) 8 samples from glacial erratic and ice-rafted boulders, (ii) 2 samples from moraine boulders, (iii) 2 samples from polished bedrock surfaces, and (iv) 1 sample from an erratic boulder deposited on one of these surfaces. {T}he {CRE} dates indicate that the onset of deglaciation started around 9.9 +/- 1.2 ka, with two phases of glacier expansion during the {M}id-{L}ate {H}olocene forming moraines at similar to 4.1 +/- 0.5 and similar to 1.0 +/- 0.2 ka, respectively. {T}he main neoglacial advances in the {AP} and the {SSI} were mostly synchronous and coincided with cold periods, as shown by other records (e.g. glacio-isostatic marine terraces, marine and lake sediments). {I}n addition, these periods of glacial expansion show a similar timing to those recorded in the {A}rctic. {T}hese results suggest that {N}eoglaciation was driven by global climate forcing in both polar areas despite temporal variations at regional and local scale.},
