| In this article, we evaluate the performance of a commercially available lifetime-based optode and compare it with data obtained by other methods. We performed a set of 10 different tests, including targeted laboratory evaluations and field studies, covering a wide range of situations from shallow coastal waters and wastewater treatment plants to abyssal depths. Our principal conclusion is that, owing to high accuracy (+/- 2 mu M), long-term stability (more than 20 months), lack of pressure hysteresis, and limited cross-sensitivity, this method is overall more suitable for oxygen monitoring than other methods. |

| Every day, the challenges to achieving conservation grow. Threats to species, habitats, and ecosystems multiply and intensify. The conservation community has invested decades of resources and hard work to reduce or eliminate these threats. However, it struggles to demonstrate that its efforts are having an impact. In recent years, conservation project managers, teams, and organizations have found themselves under increasing pressure to demonstrate measurable impacts that can be attributed to their actions. To do so, they need to answer three important questions: (1) Are we achieving our desired impact?; (2) Have we selected the best interventions to achieve our desired impact?; and (3) Are we executing our interventions in the best possible manner? We... |
