For over a month, EMBL\u2019s Mobile Laboratories fleet and the TREC sampling team \u2013 now supported by a dedicated mobile unit for water sample analysis \u2013 brought cutting-edge technologies and methods directly into the field in the Fontainebleau region of France. This mobile setup enabled real-time experiments and on-site sample processing, overcoming a key barrier to more comprehensive studies of freshwater ecosystems.<\/p>\n\n\n\n<p>Freshwater sampling required adapting and testing existing protocols originally developed for coastal environments. With input from freshwater experts, these methods were adjusted to suit the specific conditions of inland waters. The team collected water, sediment, and soil samples from a range of environments, including the River Seine, natural or under-controlled lakes, and the experimental ponds at the <a href=\"https:\/\/www.cereep.ens.psl.eu\/?lang=en\">CEREEP \u2013 Ecotron IDF<\/a> research facility. TREC researchers will now sequence these samples and conduct environmental analyses \u2013 including pollution assessments \u2013 to build a comprehensive dataset for the international scientific community.<\/p>\n\n\n\n<article class=\"vf-card vf-card--brand vf-card--striped vf-u-margin__bottom--800\" default>\n  <div class=\"vf-card__content | vf-stack vf-stack--400\">\n      <h3 class=\"vf-card__heading\">\n      Building on a longstanding collaboration with CEREEP\u2013Ecotron IDF    <\/h3>\n                <p class=\"vf-card__text\">The CEREEP\u2013Ecotron IDF and its director, Professor Samuel Abiven, were involved in the early stages of the TREC expedition, particularly in the soil and plant research components. Professor Abiven contributed to the initial site selection during TREC\u2019s preparation phase.\r\nDuring the fieldwork, the CEREEP\u2013Ecotron IDF provided several volunteers \u2014 mainly highly motivated students from the \u00c9cole normale sup\u00e9rieure (ENS) \u2014 who supported sampling and logistical activities.\r\nIn the current phase of TREC, the CEREEP\u2013Ecotron IdF serves as the main base for analyses related to continental ecosystems, focusing on the characterisation of soils and root samples collected along the expedition route.\r\n<\/p>\n      <\/div>\n<\/article>\n\n\n\n\n<figure class=\"vf-figure wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"600\" class=\"vf-figure__image\" src=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2025\/10\/Kim-Version_One-EMBL-social-media-template-June-2025-BETA-8.png\" alt=\"Photocollage of the different activities done during the TREC expedition in Fontainebleau (Ile-de-France). \" class=\"wp-image-76731\" srcset=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2025\/10\/Kim-Version_One-EMBL-social-media-template-June-2025-BETA-8.png 1000w, https:\/\/www.embl.org\/news\/wp-content\/uploads\/2025\/10\/Kim-Version_One-EMBL-social-media-template-June-2025-BETA-8-300x180.png 300w, https:\/\/www.embl.org\/news\/wp-content\/uploads\/2025\/10\/Kim-Version_One-EMBL-social-media-template-June-2025-BETA-8-768x461.png 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption class=\"vf-figure__caption\">Credits: Antonella Ruggiero\/EMBL, Thomas Haize\/EMBL&nbsp;<\/figcaption><\/figure>\n\n\n\n<p>To round off the expedition, the sampling teams took part in F\u00eate de la Science week, joining forces with EMBL\u2019s <a href=\"https:\/\/www.embl.org\/about\/science-education-public-engagement\/\">Science Education and Public Engagement (SEPE)<\/a> and Ecotron teams to bring science to life for the public.
