On the application of alkenone- and GDGT-based temperature proxies in the south-eastern Brazilian continental margin

•The applicability of U37K' and TEX86H proxies was investigated in the Campos Basin.•In general, reconstructed and measured temperatures correlate well for both proxies.•Coastal upwelling locally affects the proxies.•No effect of terrestrial input on TEX86H values was found.•U37K' and TEX86H can be used for paleoclimate studies in the SE Brazilian margin.
