Overview and Introduction

The purpose of this webpage is to provide a location for posting of datafiles with ecological information on freshwater algae living in rivers, lakes, streams and wetlands. This site helps fulfill the objectives of a group of algal ecologists who met at the 2002 Annual Meeting of the North American Benthological Society to discuss ways to develop and share ecological data on freshwater algae. (See meeting notes prepared by Jennifer Winter.) 

This site is available for posting a wide variety of information, including text files, spreadsheets, databases, presentations and links to internet resources.  Anyone can contribute. Just click the submit link below and follow the instructions. In addition to providing a data file and / or web address, you will be asked for a brief description, including pertinent references, and your name, institution, and email address. Files are added to the website automatically and will be immediately available. We recommend adding a .txt or other type of file that will provide contact information such as your email and mailing address, and other information describing your data files.

One or more related files are submitted as a group. Contributors will be asked to provide a name and description for the group as well as names and titles for the files. Both will be used on the website to label and describe the data and files provided. To post a website link to the data files, simply provide the information required on the "submit" page, except for file names.

This website is administered by the Phycology Section of the Patrick Center for Environmental Research at the Academy of Natural Sciences, in Philadelphia.  All content will be publicly available for download and use.  Content of files, and instructions for opening files or using applications associated with the files, are the responsibility of the contributor.  Website administrators will not provide support beyond that necessary to add files and information to the site.

Please contact the Phycology Section at with questions about submitting files. In particular, we are able to update or remove files you have already submitted.
