Hydrology and Earth System Sciences:

Calibration of groundwater seepage against the spatial distribution of the stream network to assess catchment-scale hydraulic properties – 6 September 2023

We propose a model calibration method constraining groundwater seepage in the hydrographic network. The method assesses the hydraulic properties of aquifers in regions where perennial streams are directly fed by groundwater. The estimated hydraulic conductivity appear to be highly sensitive to the spatial extent and density of streams. Such an approach improving subsurface characterization from surface information is particularly interesting for ungauged basins.

For the first time, EGU organized a Peer Review Training in September and October this year. It was attended by 50 participants, most of whom were early career scientists with little to no background in the peer review process. The training comprised three online sessions and an at-home exercise of reviewing real manuscripts. And of course, with feedback being key in such trainings, all participants received individual feedback from the training facilitator and the EGU editors.

So how did this training benefit participants? EGU Media Officer Gillian D’Souza and EGU Editorial Manager Eduardo Queiroz Alves sat down with Kifle Zeleke Aregahegn to hear his experiences and takeaways from the training. Read on for excerpts from the discussion:

Hi Kifle! Can you share your overall experience with the EGU Peer Review Training? Did it meet most of your expectations?

Yes, the EGU peer review training met most of my expectations. I wanted to learn what to do as a peer reviewer, as well as how peer reviewers and authors interact over scientific manuscripts. This kind of training helps build understanding between peer reviewers and the authors. Apart from the importance and responsibilities of peer reviewers, the training helped me understand how to prepare a peer review report and the ethical considerations that need to be considered while writing these reports.

How did the interactive nature of the training enhance your learning compared to other training methods you may have experienced?

The practical approach of the training certainly made it different from other methods. After an informative introduction, we were assigned to peer review a manuscript submitted to Atmospheric Chemistry and Physics (ACP).

In most cases for a training such as this, the introduction is assumed to be good enough to perform peer review. However, the EGU peer review training I had was far more than that!

I received two rounds of feedback from senior reviewers and editors, directly about my method of review and from an overall broader perspective. This helped me better understand the process of manuscript review. I think every publisher should have such initiatives in place to provide training for young, interested scientists.

Were there any specific skills or insights you gained during the training that you found particularly valuable?

The training was a good opportunity for us to play a future role in the research community and to gain valuable experience in improving our scientific research writing. It helped me build my scientific knowledge on how to write a peer review report and understand the reviewers’ point of view from the authors side.

Would you recommend the EGU Peer Review Training to your colleagues?

Yes, the EGU Peer review training is helpful not only for peer reviewing a manuscript but also for writing manuscripts. Since peer review can make the scientific process smoother and improve the quality of manuscripts for publication, I would recommend this training to my colleagues and peers as well. Although every trained person may not necessarily become a peer reviewer, knowledge of the process will definitely make the peer review process a whole lot easier.

In your opinion, would you say such trainings are necessary? Why?

Absolutely! This kind of training is very important for both authors and reviewers.

Having more trained reviewers, especially enthusiastic and motivated early career scientists, may resolve the burden that falls on most editors and senior reviewers.

The more peer review trainings made available to scientists, higher is the possibility to match reviewers to a specific subject area. As peer review requires expertise in the field, an intimate knowledge of research methods, a critical mind, the ability to give fair and constructive feedback, and sensitivity in communicating with authors, this kind of training plays an important role in building suitable reviewers. As for the authors, the manuscript is peer reviewed by a subject matter expert thoroughly and professionally.

What are the top three tips you learned during the training?

I learned many things from the training but the most important tips are:

1. Consider the author’s points of view, and ensure your feedback is clear and easy to understand. Avoid making any personal comments during the course of peer review.
2. Subject area expertise is very important, but so is knowing how to approach and write peer review reports.
3. The process of peer review is to help authors avoid rejection by meeting the publishing standards of the journal. So peer reviewers help both authors and editors toward a smoother publication journey.

In addition to the points I mentioned above, I think most senior reviewers and editors spent a lot of time and energy in making this EGU training effective and valuable. I am very grateful to have been part of this opportunity!

Kifle Zeleke Aregahegn completed his B.Sc. in Chemistry from Addis Ababa University – Ethiopia, and his PhD in Chemistry in 2014 from the University Claude Bernard Lyon 1 at Lyon.

Machine learning for numerical weather and climate modelling: a review – 13 November 2023

Machine learning (ML) is an increasingly popular tool in the field of weather and climate modelling. While ML has been used in this space for a long time, it is only recently that ML approaches have become competitive with more traditional methods. In this review, we have summarized the use of ML in weather and climate modelling over time; provided an overview of key ML concepts, methodologies, and terms; and suggested promising avenues for further research.

Universal differential equations for glacier ice flow modelling – 15 November 2023

We developed a new modelling framework combining numerical methods with machine learning. Using this approach, we focused on understanding how ice moves within glaciers, and we successfully learnt a prescribed law describing ice movement for 17 glaciers worldwide as a proof of concept. Our framework has the potential to discover important laws governing glacier processes, aiding our understanding of glacier physics and their contribution to water resources and sea-level rise.

Alpine hillslope failure in the western US: insights from the Chaos Canyon landslide, Rocky Mountain National Park, USA – 4 December 2023

In this paper, we investigate the 28 June 2022 collapse of the Chaos Canyon landslide in Rocky Mountain National Park, Colorado, USA. We find that the landslide was moving prior to its collapse and took place at peak spring snow melt; temperature modelling indicates the potential presence of permafrost. We hypothesize that this landslide could be part of the broader landscape evolution changes to alpine terrain caused by a warming climate, leading to thawing alpine permafrost.

In 2023, EGU offered Peer Review Training for the first time, over three virtual sessions in September and October 2023, with a little homework in between. With more than 100 applications, from which we chose 57, mostly Early Career Scientists (ECS) to fill the available places, the desire for this kind of training in the EGU community was clear. About 80% of the participants completed the training and drafted peer review reports for  manuscripts, either open to discussion or already published in one of  EGU’s 19 Open Access journals. The training facilitator, Professor Gene Rankey (University of Kansas), led the training which was supported by EGU and its Publications Committee. Together with 13 editors representing 11 of our journals, he provided individual feedback on the reports, the participants worked to improve them and, in some cases, uploaded their reports to the respective journal website as a part of the EGU Public Peer Review process. Following this great event, we want to address three of the most common myths or misconceptions the trainees identified, and how they can be debunked!

1. Peer review only benefits authors

While there is no doubt that peer review is essential to improve the overall quality and credibility of scientific papers, it also offers benefits to the referees involved in the process. By peer reviewing manuscripts, you hone your attention to detail, improve your writing skills, and gain valuable insight into the publishing process. Being a referee can also enhance your visibility, making you better known in the academic community, especially among editors (who tend to be senior career researchers). On top of that, additional recognition is also possible from platforms such as the Web of Science.

2. Early Career Researchers cannot review papers (especially if you haven’t yet finished a PhD)

This is a very common misconception. The reality is that senior researchers are usually busy with other academic commitments and therefore do not accept invitations to review. As a result, it has become increasingly difficult for journals to find referees for their manuscripts, which has a direct impact on an important aspect of the peer review process: timeliness!

Figure 1. Word cloud constructed with the responses of the participants when asked to complete the following statement “My confidence as a peer reviewer would grow if I….”

ECS tend to have more time and motivation to prove themselves in their field, which makes them excellent candidates for providing thorough reviews. The potential of ECS reviewers was demonstrated in the EGU’s peer review training when the trainees used real manuscripts to complete their reviews and submitted them to the review process straight away. As an extra assist to the newly trained reviewers, they were all added to EGU’s referee database after the course, setting them up to start receiving review requests straight away! Given that more than 50% of EGU members are Early Careers, we can’t help but imagine a future where all ECS are trained and empowered to interact with the reviewing process – creating a significant resource for journal editors everywhere!

3. Peer review is not a very transparent process

For many researchers their experience of the traditional peer review process is one obscured in shadow, where the interactions between reviewers, editors and authors are hidden and unclear. Some publishers claim that they cannot discuss the peer review process of a paper with anyone except the authors, but there are many benefits to conducting peer review out in the open.  Since 2001, EGU has used a multi-stage interactive public peer review process, where every aspect of the review process from submission to solicited reviews to corrections are shared publicly and open access, connected to the finished paper. This  transparent process reflects EGU’s values, as we believe that all the collaborations and exchanges between authors, editors, reviewers and the broad scientific community need to happen in the public sphere. But in addition to this the public peer review process provides extra benefits, such as a greater accountability for reviewers to write respectful and constructive reviews, as well as an excellent way to demystify publishing for new researchers – especially those who are first generation academics.

These three myths represent just a few examples of the dynamic and fruitful discussions we had during the training, showing how important these kinds of interactive peer review training courses are. The training received very good feedback from both editors and participants and we are excited to continue to expand this training for our wonderful community of EGU members, editors and reviewers – so stay tuned for future opportunities!

Figure 2. Applicants were asked to choose up to 3 EGU journals they would like to review for. Although there is overlap in the subjects covered by different journals, each publication has a different emphasis. Most of the participants chose 3 options, indicating their broad research interests.

Academic publishing has considerably evolved in response to technological developments. Current discussions revolve around the rise of generative Artificial Intelligence (AI) tools or Large Language Models (LLM). They exceed the capabilities of simple spelling and grammar checkers or translation software and their use in the publication process has several implications that need to be considered.

LLM are powerful writing assistants – you may have heard of ChatGPT and what it can do, for example – that can be harnessed to generate scholarly text. Following the prompt of a human user, these tools create textual content based on the huge datasets they have been trained on. For native English speakers, they can aid with the structuring and organizing of papers, ensuring that ideas and concepts are presented in a logical and clear way. On the other hand, researchers whose primary language is not English may benefit from the improvement of grammar, syntax, and vocabulary, as well as from guidance with the nuances in English writing. However, although outputs are presented in a very credible tone, mimicking human writing styles, the information is not always accurate, and citations are often fabricated. So much so that ChatGPT now presents a disclaimer: “ChatGPT can make mistakes. Consider checking important information.”

Figure 1. The input box of ChatGPT provides a disclaimer.

The careless use of these so-called Chatbots may lead to the publication of papers of low scientific quality, including misleading and/or incomplete information. However, it is worth mentioning that the identification of such papers can be facilitated by employing open and transparent peer review practices, like those utilized in the EGU journals. This can happen in basically two ways: first, authors may feel more inclined to submit carefully prepared manuscripts in an open peer review system, knowing that the public will have access to their work before publication. Second, the interactive discussion stage before publication includes the participation of the scientific community, enhancing the evaluation of the manuscript.

Like other segments, publishing may benefit from AI-based tools for the automation of laborious tasks. Applying AI tools to the detection of fraudulent practices and duplicate images, language improvement, and the identification of suitable reviewers could help with the optimization of publishing workflows. Other applications of AI require more careful consideration. For instance, in addition to generating text from scratch, LLM are also able to summarize, rephrase and comment text when provided with it. This bears implications for peer review, a cornerstone of the scientific publishing process.

Indeed, the use of Chatbots to both write and review scientific papers could lead to a situation in which AI evaluates content generated by AI, undermining a core principle of the peer review process: expert evaluation by peers.

Moreover, there may be confidentiality concerns associated with providing manuscript data to AI tools prior to publication. Therefore, although these tools can currently support reviewers, they should not be used as independent referees of scientific manuscripts.

Figure 2. Robot reviewing a scientific paper. Image created by DALL.E 2, Buriak et al. (2023), ACS Energy Lett. 2024, doi.org/10.1021/acsenergylett.3c02586

To maintain the integrity of the scientific publishing process, human oversight is essential. Both authors and reviewers offer critical thinking that surpasses the capabilities of AI tools. Moreover, as these tools lack accountability for the content they generate, they cannot replace human expertise and judgement. In today’s academic landscape, initiatives such as the hands-on EGU peer review training are paramount to the development of well-trained individuals who will help maintain rigorous and ethical scholarly standards in the presence or absence of AI-tools. Beyond improving the overall quality of manuscripts for publication, participants are trained to evaluate the significance and originality of the research presented, which is something that chatbots are unable to do.

The importance of writing papers is immense in the current academic system that uses publications as an important metric of a researcher’s impact. In this context, researchers should make responsible use of new tools to improve their manuscripts. Similarly, publishers are also experimenting with responsible ways of integrating AI-tools in the review process. However, it is important to be cautious due to the many limitations and ethical issues mentioned above. For this reason, EGU has recently released guidelines for the use of AI-based tools in the publication process. We hope that this will help ensure the ethical use of AI tools in the rapidly evolving landscape of scholarly communication.
