Ground-truthing Marcott

Jan 8, 2015 – 10:35 PM

The MD99-2275 core offshore Iceland is a very high-resolution ocean sediment core, results of which over the past millennium have been discussed here from time to time. Alkenone and diatom results for the last millennium have been available for about 10 years. MD99-2275 results were used in PAGES2K Arctic and Hanhijarvi 2013, also Trouet et […]

PAGES2K vs the Hanhijarvi Reconstruction

Oct 7, 2014 – 11:04 PM

The PAGES2K (2013) Arctic reconstruction of Kaufman et al has attracted considerable attention as a non-Mannian hockey stick. However, it’s been fraught with problems since day one, including a major re-statement of results in August 2014 (McKay and Kaufman, 2014 pdf), in which Kaufman conceded (without direct acknowledgement) Climate Audit criticism that their results had been […]

Alkenone Divergence offshore Iceland

Apr 10, 2013 – 10:35 AM

The longest very high-resolution alkenone core that I’m aware of is Sicre et al’s MD99-2275 (plus splices) from offshore Iceland (67N 18W). It is 4550 years long, its most recent value is 2001AD and its resolution is 4 years. Marcott used nearby core JR51GC-35 (also at 67N 18W), also an alkenone record, which had a […]

The Trouet Ocean Proxies

Apr 14, 2009 – 11:45 AM

Here are the ocean proxies used in Trouet et al. As usual in Team studies, it is a total mystery how they are selected. Trouet et al is a bit different from usual Team studies in that it argues for a MWP-LIA global reorganization, something that I’ll get to soon. Today, I want to chat […]

Day Two at AGU

Dec 13, 2006 – 8:52 AM

It is impossible to convey the overwhelming number of papers and presentations here. Through the week, my notes have invariably deteriorated. By the time you get home, they are unintelligible. I’ m going to diarize them a little — so I don’t forget totally and to share a bit of the experience. (And since CA […]
