Abstract
A wide variety of methods exist to carry out ecological monitoring of lake ecosystems, understand their biodiversity and analyze their functioning. Among these methods, scientific diving, which is widely used in the marine environment, is an original approach that brings possibilities and complementarities to the technical means deployed from the surface. It allows scientists to immerse themselves in their study environments, to observe, instrument and study a territory that is still poorly known and, above all, invisible from the terrestrial world. In this article, we illustrate the contributions and limitations of scuba diving or freediving in lakes based on concrete cases carried out over the last six years by certified divers from research units associated with the Research and Development department of the OFB-INRAE-USMB dedicated to lake ecosystems, named ECLA (https://poleecla.fr/).
