153-lake Norwegian training set (Brooks and Birks 2000, 2001); NOT corrected for isostatic rebound

the data include some additional core levels compared to the original publication. Chronological data published in: Bjune AE, Bakke J, Nesje A, Birks HJB (2005) Holocene mean July temperature and winter precipitation in western Norway inferred from palynological and glaciological lake-sediment proxies. The Holocene 15: 177-189.

TEX86-inferred temperature only reliable from 15.2 to 1 ka, prior to that GDGTs influenced by soil input. Justification from the paper to use the marine calibration curve at this lake site: "Lake Victoria surface sediment samples plot anomalously warm in the global lake calibration plot (Powers et al., 2010), but yield LST similar to those of present day when using the global marine calibration line (Kim et al., 2010). We speculate that a calibration offset for Lake Victoria may be due to a lack of a permanent chemocline and anoxic deep water, similar to that of Lake Turkana, which also shows surface sediments that plot on the warm side of the global lake calibration curve and fit the marine TEX86 calibration curve (Berke et al., 2012). Thaumarchaeota are known to be ammonia oxidizers (Konneke et al., 2005; Wuchter et al., 2006) and therefore may be nourished by the proximity of an oxic and anoxic water boundary where turbulent mixing can provide an ample supply of ammonia across the chemocline (Konneke et al., 2005; Coolen et al., 2007; Blaga et al., 2011). In the absence of such conditions, such as in the oceans and in Lake Victoria, a different community of Thaumarchaea may dominate and generate GDGTs that more closely tracks the marine TEX86 calibration curve."
