MARGO The acronym MARGO is short for "Multiproxy Approach for the Reconstruction of the Glacial Ocean surface". Given the perspective for a single multi-proxy reconstruction for the glacial surface ocean conditions which should be the final product of MARGO and considering the individual proxy compilations presented in this volume, we would like to end this preface with some general thoughts addressing the challenge that the compilation of a unique multi-proxy SST/SSS/sea-ice data set or map presents.

Following on from the model set by initiatives such as CLIMAP (Climate long-range investigation, mapping, and prediction) and MARGO (Multiproxy approach for the reconstruction of the glacial ocean surface), our aim is to bring together leading experts.

Multiproxy approach for the reconstruction of the glacial ocean surface (MARGO). The Multiproxy Approach for the Reconstruction of the Glacial Ocean surface (MARGO) project produced a reassessment of LGM sea surface temperatures (SST) (Kucera et al., a, MARGO Project Members et al., ).

Now, an expanded and improved reconstruction of LGM temperatures has been assembled by Waelbroeck et al. in the MARGO (Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface) project.

Incorporating a wide variety of temperature proxies and a spatially better-resolved set of data, MARGO strengthens many of the conclusions. We present LGM simulations from the Paleoclimate Modelling Intercomparison Project, Phase 2 (PMIP2) and compare these simulations to proxy data collated and harmonized within the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface Project (MARGO).

As compared to modern ocean state estimation, challenges include large and uncertain errors, data sparsity, and poorly known atmospheric circulation.

The initial focus is on sea surface temperature and sea ice extent data compiled and unified by the Multiproxy Approach for the Reconstruction of the Glacial Ocean surface (MARGO) project.

The Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface (MARGO) compilation of LGM surface ocean temperature estimates (Waelbroeck etal. ) extends theprevious work ofGlacial Atlantic Ocean Mapping (GLAMAP; Pflaumann et al.

)and Climate: Long-range Investigation, Mapping, and Pre. The ocean state from each simulation is confronted with a data set from the Multiproxy Approach for the Re- construction of the Glacial Ocean (MARGO) sea surface temperatures (SSTs), some reconstructions of the palaeo- circulations and a number of sea-ice reconstructions.

We use the method of least squares with Lagrange multipliers to fit an ocean general circulation model to the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface (MARGO) estimate of near sea surface temperature (NSST) at the Last Glacial.

of SST reconstructions undertaken by the MARGO (Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface) project. The objective has been to compile and analyse available estimates of LGM SSTs based on all prevalent microfossil-based (i.e., transfer functions based on planktonic foraminifera, diatoms, dinoflagellate.

Large-scale surface temperature reconstructions based on multiproxy techniques often have a time resolution as fine as decades or individual years; they also enable researchers to estimate the statistical uncertainties associated with the reconstruction technique, as described in Chapter 9.

The proxy data were simulated by drawing data from four different model simulations at the ocean sediment core locations of the Multiproxy Approach for the Reconstruction of the Glacial Ocean surface (MARGO) project, and perturbing these data with realistic noise estimates.

The publication of the SST reconstruction of MARGO (Multiproxy Approach for the Reconstruction of the Glacial Ocean surface) was the culmination of an international collaboration to update and improve LGM SST reconstructions (MARGO Project Members ).
