The AlgaTerra Information System


Information on microalgae is inhomogenous with respect to accessibility, relevance to current research, quality of data and media. Accessibility means fragile original objects, handwritten manuscripts and published papers spanning the late 18th until the 21st century. Embedded in much outdated information there is nonetheless a core of historical data which is needed for current and future research.
Differences in the data quality of historical and recent sources are the result of varied methods, interpretations and state of knowledge. Hand drawings, published figures and digital images of microalgae lead to a high diversity of media.
Current internet databases cover single aspects of information. AlgaTerra as an internet available Information System will bring together different aspects of phycological research. The Information System will be managed and supported over the long-term by the Botanic Garden and Botanical Museum Berlin-Dahlem as part of its scientific information services.

Aims of the project

  • a. modeling of a complex database structure as a part of the "Berlin Taxonomic Information Model"
  • b. development and implementation of a database for terrestrial microalgae
  • c. development of a user-orientated web-interface

The pilot phase of the AlgaTerra information system ended in February 2005.
