Acknowledging GLEON


The Global Lake Ecological Observatory Network (GLEON) is a grassroots organization. Recording progress is important to grow and sustain GLEON. This growth and sustainability will be aided in part by the visibility of GLEON in the published literature, scientific presentations, and web-based materials. If you feel that the work you are publishing, presenting at meetings, or posting on your own website benefited from your participation in GLEON, its existence, or its products, it would be appropriate to acknowledge GLEON.

Published Literature


A suggested short acknowledgment in a paper might be:


"This work benefited from participation in or use of the Global Lake Ecological Observatory Network (GLEON)."


Add to this the specific acknowledgement of funding. For example:


"This work benefited directly from support provided by the NSF Award #___."


On a slide for a meeting, it might be appropriate to simply list the GLEON acronym -- or one of the logos below -- where you acknowledge your other collaborators or collaborating organizations.


Please send us a copy of your paper or presentation or a link to it.

Committee for inClusive Collaboration

Maintaining a welcoming, inclusive, inspirational, and productive environment remains a very high priority for GLEON. As the nature of the organization evolves through programmatic growth, turnover in personnel (plus growth by individuals), and a natural shift in science and technology emphasis, we felt it was critical to have multiple mechanisms for monitoring and evaluating GLEON's organizational environment. One mechanism was the creation of a feedback survey that all GLEON participants take at the end of GLEON meetings. A second mechanism was the formation of a committee to evaluate and respond to survey results, as well as other, less formal feedback. Details of this committee follow.


A task force was convened in Madison, Wisconsin, September 3rd and 4th 2008 to formalize our evaluation approach. Out of this meeting came the formation of the Collaborative Climate Committee (CCC). The initial goals of the CCC were to make recommendations to the GLEON and RCN Steering Committees on how to better integrate students into GLEON and to take positive action to improve student experiences at the GLEON 7 meeting in Sweden. However, the CCC quickly expanded its scope to include attention to all of the GLEON membership. Voluntary participation in the task force was solicited by Paul Hanson from the GLEON RCN Steering Committee. Others were asked to participate because of their experience with graduate students, their expertise with organizational issues, or to represent the diversity of interests from various career stages/types, science and technology expertise and geography within GLEON. In 2020, the CCC decided to rename itself the Committee for inClusive Collaboration to better describe its purpose.

      Student Workshop Facilitators/Organizers (chosen by the GSA): The GSA holds regular student workshops and seeks workshop leaders and facilitators across a wide variety of topics. If you are interested in leading a workshop at a future All-Hands Meeting, please contact the current GSA leaders).

      GSA subcommittees: The GSA has other opportunities for students within the GLEON network, including serving on communications or poster session subcommittees.


Other Leadership Opportunities

Host an All Hands' GLEON Meeting, a Working Group workshop or meeting, or a session at a conference

GLEON All Hands' Meetings are hosted by GLEON site members and organized by Program (Meeting) Committees. These committees are facilitated by the SC co-chairs and populated with meeting hosts, SC members and the general GLEON community. Other opportunities for hosting meetings include leading small, focused Working Group meetings between All Hands' Meetings, and by hosting GLEON gatherings, sessions or workshops at national or international meetings (e.g. ASLO, SIL, etc.).


Lead or co-lead a Working Group

The bulk of GLEON All Hands' Meetings are invested in Working Groups, initiated and led by GLEON members who communicate both electronically and in person between All Hands' Meetings. Members are self-organized at both the group and sub-team levels, keeping the group efforts on-task and productive.


Moderate/Facilitate at an All Hands Meeting

GLEON meetings are always led by a number of active GLEON members in a voluntary, dynamic and collaborative fashion. If you are interested in moderating or facilitating at an All Hands' Meeting, get in touch with Steering Committee co-chairs.


Create GLEON Science deliverables

Manuscript and software development are led by motivated GLEON individuals. All GLEON members are encouraged to make intellectual and data contributions to science deliverables on active projects, taking the exploratory brainstorms not only to a collaborative process but to scientific significant products.


Education and Outreach

Connect with communities outside of GLEON (e.g. citizen-scientists, classrooms, labs, etc.) or generate outreach/educational content for such community activities. Currently, little educational or outreach content for network science exists. If you use network data in outreach, classrooms or labs, we welcome you to share your experiences and/or content with other GLEON members.


**New opportunities are always emerging. If you have a good idea for something you want to do or lead in GLEON or if you would like more information on one of the opportunities on this page, please feel free to contact us.
