EARTH SYSTEM SCIENCE DATA
A global pigment database consisting of 35 634 pigment suites measured by high performance liquid chromatography was assembled in support of the MARine Ecosytem DATa (MAREDAT) initiative. These data originate from 136 field surveys within the global ocean, were solicited from investigators and databases, compiled, and then quality controlled. Nearly one quarter of the data originates from the Laboratoire d'Oceanographie de Villefranche (LOV), with an additional 17% and 19% stemming from the US JGOFS and LTER programs, respectively. The MAREDAT pigment database provides high quality measurements of the major taxonomic pigments including chlorophylls a and b, 19'-butanoyloxyfucoxanthin, 19'-hexanoyloxyfucoxanthin, alloxanthin, divinyl chlorophyll a, fucoxanthin, lutein, peridinin, prasinoxanthin, violaxanthin and zeaxanthin, which may be used in varying combinations to estimate phytoplankton community composition. Quality control measures consisted of flagging samples that had a total chlorophyll a concentration of zero, had fewer than four reported accessory pigments, or exceeded two standard deviations of the log-linear regression of total chlorophyll a with total accessory pigment concentrations. We anticipate the MAREDAT pigment database to be of use in the marine ecology, remote sensing and ecological modeling communities, where it will support model validation and advance our global perspective on marine biodiversity. The original dataset together with quality control flags as well as the gridded MAREDAT pigment data may be downloaded from PANGAEA: http://doi.pangaea.de/10.1594/PANGAEA.793246.

We are grateful to two anonymous reviewers for their evaluation of this manuscript. We thank Erik Buitenhuis for producing the gridded netCDF product, Stephane Pesant for archiving the data on www.Pangaea.de, and Dave Carlson and Hans Pfeiffenberger at ESSD for their patience. We would like to further acknowledge Gerald Moore, Denise Cummings, Tony Knap, Dave Robins, Dave Suggett and Guy Westbrook for their HPLC data contributions. We are equally grateful for all the project PIs who contributed data, as well as for the anonymous staff who took part in the sampling work during the cruises, who carried out the HPLC analysis, and without whom the construction of such a database would not have been possible. Most of the data from the LOV database were acquired as part of the French national programs JGOFS-France, PROOF and CYBER, which were funded by CNRS-INSU.
