Ocean2k NG 2015 F2a mod

Figure. Results of the global sea surface temperature compilation from Ocean2k: A cooling over the past two millenium was reversed only in the most recent two centuries. (More in Figure 2a in the paper and Supplementary Tables S6 and S13 and Fig S8).

This paper provides the missing ocean component to the continental-scale temperature reconstructions produced by the PAGES2k Consortium "Continental-scale temperature variability during the past two millennia"; published in Nature Geoscience in 2013.

The Ocean2k study based on annual growth bands in corals that show the year-to-year changes in detail over the past 400 years is "Tropical sea-surface temperatures for the past four centuries reconstructed from coral archives" by Jessica E. Tierney, Nerilie J. Abram, Kevin J. Anchukaitis, Michael N. Evans, Cyril Giry, K. Halimeda Kilbourne, Casey P. Saenger, Henry C. Wu and Jens Zinke; published in Paleoceanography in 2015.

Ocean2k Proposals received

The PAGES 2k project is accelerating on multiple fronts. Besides the very active regional groups, several trans-regional projects are busy developing synthesis products focusing on research questions that cut across regions.

The 2k Network is larger than ever (with close to 600 mailing lists subscribers), prominent at meetings (e.g. upcoming sessions at AGU and EGU), and in the media.

For the 1st Ocean2k workshop over a dozen proposals were received involving several general research themes centered on database/methods, observation-simulation comparisons, salinity reconstructions; and tropical, Mediterranean and North Atlantic dynamics.

All are expected to be supported and discussed in-person by their representatives in Barcelona (6-8 Oct 2015).

More information coming soon about the organization and planning for this workshop.
