Abstract

A global pigment database consisting of 37103 pigment suites measured by high performance liquid chromatography was assembled in support of theMARineEcosytemDATa (MAREDAT) initiative. These data originate from 136 field surveys within theglobal ocean, were solicited from investigators and databases, compiled, and then quality controlled. Nearly one quarter of the data originates from the Laboratoired’Océanographie de Villefranche (LOV), with an additional 20 % and 17% stemming from the US JGOFS and LTER programs, respectively. The MAREDAT pigmentdatabase provides high quality measurements of the major taxonomic pigments including chlorophyllsaandb, 19’butanoyloxyfucoxanthin, 19’hexanoyloxyfucoxanthin, allox-10anthin, divinyl chlorophylla, fucoxanthin, lutein, peridinin, prasinoxanthin, violaxanthinand zeaxanthin, which may be used in varying combinations to estimate phytoplank-ton community composition. Quality control measures consisted of flagging samplesthat had a total chlorophyllaconcentration of zero, had fewer than four reported accessory pigments, or exceeded two standard deviations of the log-linear regression of total chlorophyllawith total accessory pigment concentrations. We anticipate the MAREDAT pigment database to be of use in the marine ecology, remote sensing andecological modeling communities where it will support model validation and advanceour global perspective on marine biodiversity. The original dataset together with qualitycontrol flags as well as the gridded MAREDAT pigment data may be downloaded from PANGAEA:http://doi.pangaea.de/10.1594/PANGAEA.793246.
