Limnoseries: Workshops & Lectures

Limnoseries: Workshops & Lectures 2022

Back by popular demand, the GLEON GSA Limnoseries: Workshops & Lectures 2022 will run again every month beginning in February. Recordings will be added to a playlist on the GLEON YouTube channel.

28-02-2022, 11:00 AM  (UTC): Are our models keeping pace with the evolving data deluge?
Lecture by Dr. David Hamilton
In this lecture, opportunities to exploit sensor data for water model input data, calibration and validation will be discussed. Participants will be asked to consider the key elements of good modelling strategy. These elements are critical to fully implement new opportunities arising from harmonized data, data assimilation and high-performance computing environments.
31-03-2022, 1:00 – 4:00 PM (UTC): Understanding Uncertainty in Ecological Forecasts
Workshop by Dr. Tadhg Moore
The workshop will cover an introductory lecture to ecological forecasting, followed by activities where students build a model and generate forecasts to explore different sources of uncertainty and also learn ways in which to quantify, reduce and communicate uncertainty.
26-04-2022, 3:00 – 4:00 PM (UTC): Using Data Visualization to Communicate Science
Lecture by Dr. Cee Nell (they/them)
Data visualization is a powerful tool for communicating science. Effective visualizations can translate complex data into compelling visuals that are engaging, broadly understandable, and ultimately increase the impact of scientific work. So what makes an effective data visualization? Dr. Cee Nell (they/them) will discuss different ways to approach a data viz, how to leverage information design to communicate a message, and show a lot of data viz along the way. 


Limnoseries: Workshops & Lectures 2021

The GSA workshop sub-committee is excited to bring you GLEON GSA Limnoseries: Workshops & Lectures 2021. This exciting new GLEON event will run every other month, starting in February 2021 and bring you lectures and hands-on workshops covering the length and breadth of the GLEON network. Lectures will cover topics from physics to fish, and workshops from data collection, data analysis and science communication. The series will enable students and faculty members alike to gain new knowledge and skills and for individuals to present and share their expertise with their GLEON colleagues. As recordings are available, they will be added to the Limnoseries playlist on GLEON's YouTube channel.

Limnoseries 2021 First Edition
The first edition of the GLEON Limnoseries will be on the 23rd and 26th of February.
23-02-2021, 8:00 CST / 15:00 CET: Introduction to LaTeX
Workshop by Johannes Feldbauer & César Ordóñez
A short introduction into the world of LaTeX, an old and powerful typesetting software that can be used to produce beautiful documents. LaTeX is a markup language like Markdown, which means that you write a source code with commands that tells the software about the structure of your document, which then is compiled into a pdf document. This may seem a little bit cumbersome and while LaTeX has a quite steep learning curve there are definite advantages in using LaTeX to produce your manuscript. We want to explain to you why we think LaTeX is worth the effort and start together on your first .tex document. Click here to view the LaTeX Workshop recording.
26-02-2021, 8:00 CST / 15:00 CET: Science Communication
Lecture by Rebecca North
Science communication is critical for sharing your hard-earned results and data. This presentation will provide tips on giving both oral and poster presentations to a variety of audiences. As scientists, we are also storytellers, and there are some tricks-of-the-trade for making your stories stick and some pitfalls to avoid. At the end of this presentation you should be better prepared to present effective and engaging scientific presentations. Click here to view the Science Communication Lecture.
Limnoseries 2021 Second Edition
The second edition of the GSA Limnoseries will be on March 31st and April 23rd 2021. Click here to view the flyer.
31-03-2021, 07:00 (UTC): Timeseries Analysis for Ecologists
Workshop by Ulrike Obertegger
An introduction to the challenges of time-series data and demonstration of different analysis methods. This is not a technical course but a practical demonstration of what can be done to solve certain ecological questions. All the analyses are done in R and thus a basic understanding of R coding is helpful. Outline:
  • Introduction on basic terminology
  • Classic time-series analyses. Mann Kendall, Sen Theil trend estimation
  • Change point analysis
  • Modeling time-series with cosine trends
  • GAM
  • Clustering of time-series with DTW
This seminar will not be recorded, so make sure to register your attendance to attend live!
23-04-2021, 16:00 (UTC): Climate drivers, morphometry factors, and thermal responses of a moderate deep tropical lake
Lecture by Gilberto Fonseca Barroso
The lecture will address Lake Terra Alta, a deep Brazilian tropical lake (Zmax = 24.22m and Zmean = 9.99m), thermal responses based on high-frequency meteorological and thermal measurements (2014 to 2018) with a low-cost buoy. Regional climate and lake morphometry indices were applied to clarify temporal thermal variability, including the 2015-16 severe regional drought.
Due to the international nature of GLEON, the organisers have aimed to schedule the series across a variety of timezones. Last months’ seminars primarily coincided with timezones in the Americas and Europe and so this month we have aimed to accomodate more members in Asia and Australasia. 
Limnoseries 2021 Third Edition
The third edition of the Limnoeries will be a workshop on the 20th of May.
20-05-2021, 15:00 (UTC): Introduction to Ecological Forecasting Workshop by Tadhg Moore
In this workshop, students will apply the iterative forecasting cycle to develop an ecological forecast for a NEON site. This workshop will introduce students to the basic components of an ecological forecast; how a simple forecasting model is constructed; how changes to model inputs affect forecast uncertainty; and how productivity forecasts vary across ecoclimatic regions.
This workshop is part of the Macrosystems EDDIE project and students who sign up for this module will be asked to take a pre and post workshop questionnaire. Virginia Tech was awarded a federal grant to study curricula that introduce macrosystems ecology and ecological forecasting concepts to students. This new curriculum is being used as part of this course. Pre and post student questionnaires are part of the curricula. As part of understanding whether this curriculum is useful for teaching students, a research project is investigating student responses. Your participation in the research aspect is not required but is appreciated. I, as the instructor, will only be able to tell that you have completed the questionnaires, not whether you have consented to have your responses included in the research project.
Limnoseries 2021, Fourth Edition
The fourth edition in the Limnoseries will be a workshop on the 15th of June.
15-06-2021, 14:00-16:00 (UTC): Introduction to lake ecosystem modelling with WET
Workshop by Tobias K Andersen
In this workshop, participants will learn how to apply the process-based lake ecosystem model, Water Ecosystems Tool (WET), on a given lake. The workshop will begin with a 20 minute lecture on the theoretical framework of WET followed by a hands-on tutorial on setting up a WET lake model with the user interface QWET. We will also explore calibration and validation of our lake model. At the end of the workshop, we will open up for a discussion of the applicability of WET, future model developments and the use of auto-calibration and sensitivity analysis with WET.
June Lecture: Characterising grazing impacts in Lough Feeagh - Maria Caldero Pascual
Limnoseries 2021, Fifth Edition
07-08-2021, 15:00 (UTC): An introduction to data.table 
Workshop by Jorrit Messman
This workshop gives an introduction to the R package data.table. This package provides an extension to data.frame and focuses on fast data handling. Additionally, it supports a clear and concise syntax. Outline:
  • Introductory presentation
  • R script walkthrough (basic and advanced data.table usage)
  • Questions and exercises
