Abstract
GEOMAGIA50.v3 for sediments is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data obtained from lake and marine sediments deposited over the past 50 ka. Its objective is to catalogue data that will improve our understanding of changes in the geomagnetic field, physical environments, and climate. GEOMAGIA50.v3 for sediments builds upon the structure of the pre-existing GEOMAGIA50 database for magnetic data from archeological and volcanic materials. A strong emphasis has been placed on the storage of geochronological data, and it is the first magnetic archive that includes comprehensive radiocarbon age data from sediments. The database will be updated as new sediment data become available. The web-based interface for the sediment database is located at http://geomagia.gfz-potsdam.de/geomagiav3/SDquery.php . This paper is a companion to Brown et al. (Earth Planets Space doi:10.1186/s40623-015-0232-0, 2015) and describes the data types, structure, and functionality of the sediment database.

Paleomagnetic data from sediments complement the wealth of data from archeological and volcanic materials covering the same period already stored within the GEOMAGIA50 database (Brown et al 2015)
Summary
The GEOMAGIA50 database for sediments is an expansion of the GEOMAGIA50 database, which previously housed only magnetic data from archeological and volcanic materials (Brown et al 2015; Donadini et al 2006; Korhonen et al 2008). The database accommodates paleomagnetic, rock magnetic, radiocarbon, and other age data obtained from marine and lake sediments deposited over the past 50 ka. More advanced queries based upon specific paleomagnetic, rock magnetic, and chronological types are accommodated. Users can generate Holocene geomagnetic field model predictions from the CALSxk and pfm9k.1a series of models (e.g., Korte and Constable 2011; Nilsson et al 2014) for the coordinates used for the data search. These data can be downloaded as .TXT files. Authors’ contributions MCB participated in the design of the database, its implementation and web design, data acquisition, and drafted the manuscript.
