Short summary
Reconstruction of past climate conditions is important for understanding current climate change. These reconstructions are derived from proxies, enabling reconstructions of, e.g., past temperature, precipitation, vegetation, and sea surface temperature (SST). Here we investigate a recently developed SST proxy based on membrane lipids of ammonium-oxidizing archaea in the ocean. We show that low salinities substantially affect the proxy calibration by examining Holocene Baltic Sea sediments.
