Dear Marmamers, With almost a week left to early-bird register for the upcoming SMM conference in October (!), my co-organizers and I wanted to bring your attention to our half-day workshop. In this workshop we will discuss the DTO-BioFlow project, how the project effectively came together, the good science that is coming out of our work, and how you can access these data, but mostly we aim to provide a practical tutorial on how to upload your F/C-POD data to be hosted the data lake (ETN/EDITO). Please see summary information below. Workshop will also be available online. See you in San Juan! Cheers, Emily T. Griffiths Title: Data Flow into the Digital Twin Ocean: Integration of C/F-POD PAM Data Workshop Summary: Marine habitats present specific and one-of-a-kind issues when it comes to observing, mapping, and monitoring biodiversity in marine ecosystems. Harmonizing these data can be a challenging effort, but necessary when looking across borders to focus on ecosystem health and species management. The core mission of the DTO-BioFlow Project (https://dto-bioflow.eu) is to unlock “sleeping” biodiversity data and enable the sustained flow of these and new data into a Digital Twin Ocean, creating a digital replica of marine biological processes transforming new and existing data flows into evidence-based knowledge. Here, we will explain how the European scientific community came together across multiple disciplines, governments, and institutions to achieve collective, internationally harmonized databases which are actively being used in operationally relevant user cases. We will highlight harbor porpoise passive acoustic monitoring (PAM) detection data collected from C/F-PODs (https://www.chelonia.co.uk). Data exported from C/F-POD proprietary software has multiple export options, including different classifications, and presently user self-documentation is the only way to capture this metadata. Furthermore, once data is processed for a specific project, it often then remains stored and unused after that project has closed. Therefore, within DTO-BioFlow, we have created a workflow application, Valkyrie, to guide otherwise unused or dormant data into the DTO data lake to have a second life. Valkyrie extracts information directly from pod files to ensure PAM data is harmonized across projects, institutions, and countries, can thereby be stored uniformly within the publicly accessible European Tracking Network (ETN, https://www.europeantrackingnetwork.org/en) database, and ultimately ported to DTO-BioFlow. The workshop will include a practical component, where data holders are guided on how to use Valkyrie to validate their C/-F-POD data, and then upload it to ETN. Efforts are underway within Europe to harmonize pod data, but this workshop would expand those efforts globally, specifically targeting underrepresented marine areas in conservation efforts. Format: The workshop will start with 1.5 hours of presentations, with open Q&As. These talks will give participants an overview of the DTO-BioFlow project and how it functions. There will be an introduction to EDITO (https://www.edito.eu), which hosts the DTO-BioFlow data lake, and how data both enters and can be extracted by users. For PAM data, there will be a focus on Valkyrie, a data-harmonizing MATLAB application that reads in the raw data files from C/F-PODs, and exports the data ready to be ingested by the ETN . The bulk of the workshop (~2 hours) will be hands-on support to help participants set up accounts with ETN and EDITO, installing Valkyrie, and uploading their first batch of data to ETN. Lastly, there will be a science-based talk from a DTO-BioFlow research project which uses harmonized data across institutions. Emily T.
