GOAL
To bring together people who are working on subterranean biology so that knowledge and information can be shared and transferred and future efforts to increase knowledge of groundwater ecosystems can be coordinated.
MISSION STATEMENT
The mission of the organizers of TGIF is to encourage collaboration and exchange of ideas and information, and to more efficiently and clearly convey and transfer information to those who need and/or use it.
PROBLEM STATEMENT
A number of people are currently working on Texas groundwater organisms, however, there is infrequent research coordination and information exchange about the diverse projects and ongoing efforts that can cause barriers for those who want to fully understand groundwater biodiversity, promote efficient dissemination, and effectively use the data for research and management purposes.
