Environmental sciences depend heavily on observational data. Successful studies of ecological processes in lakes require in-situ data that cover the relevant temporal scales from milliseconds to entire seasons. Temporal and spatial coverage requirements represent a non-trivial challenge in lake sciences, which have traditionally used sampling campaigns conducted from research vessels or anchored moorings. These come with various logistical tasks and impose constraints on data coverage. An open water platform can overcome many of these limitations by providing continuous access and a wide range of analytical capabilities in direct contact with the lake environment. A consortium of five partner institutions constructed a 10 × 10 m, open-water, multipurpose platform on Lake Geneva (Switzerland/France) for a broad range of limnological research. The LéXPLORE platform, anchored since February 2019 at a position reaching 110 m depth off the lake's north-shore, provides workspace for a large number of instruments and up to 16 staff working in parallel on individual or integrated multidisciplinary projects. The safe, dry and protected floating laboratory offers direct access to the lake environment for high-sensitivity, high-throughput analyses including those which might advance sensor technology. The platform provides flexible workspace for both high-resolution measurements and investigations of larger-scale external forcing. It thus supports multidisciplinary empirical research in limnology, atmospheric sciences, and remote sensing. This article describes the platform and how it will advance aquatic sciences. The large number of projects that have already requested access to the platform demonstrate the efficacy and necessity of the LéXPLORE concept.

LéXPLORE：日内瓦湖上的浮动实验室，提供独特的湖泊研究机会

环境科学在很大程度上依赖于观测数据。湖泊生态过程的成功研究需要涵盖从毫秒到整个季节的相关时间尺度的原位数据。时间和空间覆盖要求代表了湖泊科学中的一项重大挑战，传统上使用从研究船或锚泊系泊进行的采样活动。这些伴随着各种后勤任务，并对数据覆盖施加了限制。开放水域平台可以通过提供与湖泊环境直接接触的连续访问和广泛的分析能力来克服许多这些限制。一个由五个合作机构组成的财团在日内瓦湖（瑞士/法国）建造了一个 10 × 10 m 的开放水域多功能平台，用于广泛的湖沼学研究。LéXPLORE 平台自 2019 年 2 月起锚定在离湖北岸深度达 110 m 的位置，为大量仪器和多达 16 名并行工作的人员提供工作空间，用于单个或综合多学科项目。安全、干燥和受保护的浮动实验室可直接进入湖泊环境，进行高灵敏度、高通量分析，包括那些可能会推进传感器技术的分析。该平台为高分辨率测量和更大规模外强迫的研究提供了灵活的工作空间。因此，它支持湖泊学、大气科学和遥感方面的多学科实证研究。本文介绍了该平台以及它将如何推进水生科学。
