Thanks for taking the time to look at the report and respond with your thoughts. We very much appreciate it!
Specific to temperature, we do not know how our partner extracted data from images to determine temperature (or any parameter). We have already followed up with them to get more specific information about what exactly they did.
Regarding the depth of measurements, our “ground truthed” data were collected at a depth of approximately 0.5-1m. The sensor of the handheld device—which collected data for all parameters except for ammonia—was submerged just below the water surface. For ammonia, a sample of water was collected from the same site at approximately the same depth. This aspect of the study protocol was designed to match the procedures conducted by the ARA.
