GSA Limnoseries - Wind-induced sediment resuspension in a shallow coastal lagoon
2025-06-25 12:30 - 13:30 UTC
Presented by Daniel Chilton
Shallow lakes and lagoons typically exist in either an ecologically healthy, clear water state, or a degraded turbid water state. Wind-induced sediment resuspension can be important in maintaining a shallow lagoon in a degraded state. This presentation examines how wind-induced sediment resuspension contributes to the degraded state of the Coorong, South Australia, a shallow coastal lagoon of high ecological, social and economic importance.

World Lake Conference
2025-07-21 - 2025-07-25 | BCEC, Cnr Merivale and Glenelg Streets, Brisbane, Queensland
The 20th World Lake Conference in Brisbane (21-25 July 2025) is bringing together some of the world’s leading freshwater experts to share groundbreaking research, innovative restoration techniques, and global perspectives on Lakes as Sentinels for Integrated River Basin Management.
The World Lake Conference will be a great opportunity for GLEONites. We encourage you to attend this important event, make connections with the International Lake Environment Committee Foundation, and be part of global initiatives on lakes (e.g., World Lake Day (27 August) and the UN Resolution on Sustainable Lake Management (22 March 2022)).

United Nations World Lake Day
2025-08-27
The inaugural United Nations World Lake Day is being held on 27th August 2025. Please consider publicizing this event and doing something special to celebrate how lakes are an integral part of our GLEON community and have a critical role for people and biota across the globe.
Also, the Meanjin Brisbane Declaration on World Lake Sustainability, arising from the 20th World Lake Conference, is now available on Zenodo. There is MS Forms access for anyone who wishes to add their name to the Declaration.

GSA Limnoseries: How to Design Better Experiments
2025-09-23 14:00 - 15:30 UTC
Presented by Mridul Thomas and Ravi Ranjan
Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.

Limnoseries Workshop - Proposal Writing: Strategies for Successful Grant Writing
2025-10-14 11:00 - 13:00 (America/New_York)
Presented by Thomas Shannon
This workshop will focus on developing strategies for writing productive and successful scientific research proposals. We will focus on: 1) finding grants and navigating the diverse international granting landscape, 2) strategies for developing clear, concise, and compelling writing; 3) developing a “skeleton” for your grant application, going over the critical (and sometimes forgotten) components of the document; 4) strategies for integrating persuasive writing and scientific writing; and 5) tips and tricks for getting words on the page. Participants are encouraged to come prepared to write, and there will be opportunities throughout the workshop to practice writing short segments relevant to your own upcoming proposals or grant applications.
*Participants are welcome to join and leave according to their availability.
If you would like to attend this workshop or receive the recording, please fill in the following registration form: https://forms.gle/tbjJALRfkoeFjSgZ8

Workshops
The GLEON Student Association (GSA) workshop subcommittee is organizing three pre-recorded workshops for asynchronous viewing. The online videos will be uploaded and available a week before the virtual meeting. Check back for more details. Here is a tentative list of topics and presenters:

Spatiotemporal Analyses of Water Quality in River Basins Using Generalized Additive Models (GAM) – Diego Guimarães Florencio Pujoni, Universidade Federal de Minas Gerais
In this workshop, participants will learn how GAMs can be used to capture complex, nonlinear relationships in environmental data. We will discuss how spatiotemporal series can be decomposed into spatial and temporal components at multiple scales, and how variation partitioning can be applied to quantify the relative contributions of these components. As a case study, the workshop will focus on the Doce and Paraopeba rivers, both impacted by mine tailings from dam failures. Topics will include model specification, smoothing techniques, distributional assumptions, and diagnostic tools, emphasizing how GAMs provide a flexible framework for environmental monitoring and hypothesis testing. Hands-on applications in R will demonstrate how these models can be used to extract long-term trends, seasonality, and spatial patterns in water quality variables.
Carbon Footprint of Tropical Reservoirs and climate change – Nathan Barros, Universidade Federal de Juiz de Fora
In this workshop, we will explore how tropical reservoirs interact with environmental and climatic changes. We will review recent scientific advances in understanding these systems, including the concept of anthropogenic greenhouse gas emissions and the processes that remain overlooked in the context of emissions from tropical reservoirs. The workshop will emphasize the pathways of greenhouse gas emissions from reservoirs and compare them with those observed in natural lakes. In addition, we will discuss the carbon footprint of tropical reservoirs and its broader implications for climate change. Finally, we will outline future research directions and management guidelines to mitigate emissions and enhance sustainability.
Smart Enough? Academia and the Imposter Phenomena – Harriet Wilson, University of Stirling
Do you feel like a fraud, even while pursuing the research path you’ve worked so hard to reach? Does it feel awkward when people assume you must be “smart” just because you’re doing a PhD or describe you as an ‘expert’ in your topic? What is imposter syndrome—or is it even a syndrome at all? Should I ditch it, outsmart it, love it, or embrace it? Surprise, surprise: I don’t promise any answers. But in this session I’ll attempt to unpack this buzzword topic, distilling what I’ve learnt from a frankly ridiculous number of self-help books, to figure out what imposter “syndrome” really is, why so many academics are struggling with it, and what, if anything, we can do about it.

There is no fee for the workshops, but those interested in participating should complete a meeting registration form. A workshop Q&A session is tentatively scheduled during the virtual meeting live sessions. If you have any questions about the workshop, please contact the GSA.
Regional Gatherings

The following Regional Gatherings will be held during the week:

Regional meeting for Europe, 29 October 2025, 17:00-18:00 UTC

Network Partnership Program
The Committee on inClusive Collaboration (CCC) has revamped the Network Partnership Program (NPP) for virtual meetings. If you are New-to-GLEON and would like to have a mentor during the meeting or are an experienced GLEON member willing to help welcome a newcomer, you can sign up during meeting registration.
Purpose
The purpose of the Network Partnership (NPP) is to help New-to-GLEON participants engage in effective, friendly networking and integration into the community of people and collaboration.
NPP Roles

New-to-GLEON Partner (NP): If you are new to GLEON (first or second meeting), you have the option to choose to sign up as a NP;
GLEON Partner (GP): If this is your 3rd time or more attending a GLEON All Hands’ Meeting. You can be a faculty member, scientist, technician or student that has been to more than two GLEON events and are willing to participate in NPP in a mentoring role.

Suggested Activities and Expectations of Both Roles
The exact terms of the networking partnership will vary depending on the particular needs of your partner. Here are a few suggestions that NPP partners from the past GLEON meetings have honored and worked well:

The GLEON Partner (GP) is expected to be friendly and supportive, to make frequent contact with the New-to-GLEON Partner (NP), introduce him/her to other GLEONites, help identify similar or complementary research interests among GLEON meeting attendees and general membership.
The GP should reach out via email in advance of the meeting and visit the NP’s poster during the Poster Session and helps facilitate interactions with the audience, if need be.
NP and GP share at least one break together during the meeting.

Limnoseries Lecture November 2025
2025-11-27 14:00 - 15:00 UTC
The next GLEON GSA Limnoseries will take place on November 27 at 15:00 CET / 14:00 UTC (1 hour duration).
Drivers and impacts of long-term change in the birthplace of Limnology
Presented by Bastiaan Ibelings
In the 19th century Alphonse Forel wrote a book with the title Le Léman (Lake Geneva). A book full of observations on this large and deep lake that are still at the basis of what we do today. In his monograph Forel writes something along the lines: I propose to call this study of lakes Limnology, the Oceanography of Lakes. Limnology was born. In this lecture I will honour the legacy of Forel and discuss long-term change in the lake, drivers of change over at least the last 60 years. We will cover the impact of eutrophication followed by re-oligotrophication, resulting in the present-day question of Have we made the lake too clean? Or do blooms of toxic cyanobacteria still pose a risk, that would call for further reductions in phosphorus? We will discuss how re-oligotrophication interacts with the effects of climate change – mainly a lack of full winter overturn causing hypoxia, even in an oligotrophic lake. We will not forget to discuss a third major impact on the functioning and services of Lake Geneva, the massive invasion of the quagga mussel.
