Because of the inherent danger associated with scuba diving and the limited amount of field data that divers can collect through direct seawater sampling, the research team recognized the need to deploy data loggers at the study\u2019s in situ incubation chambers in order to obtain adequate, meaningful data.<\/p>","use_case_problem_title":"How to expand data collection in an underwater environment to evaluate carbon sequestration capacity","use_case_results":"<p>Because of the reliable, accurate, and plentiful data the HOBO loggers provide, the research team relies on scuba divers only for initial deployment of the loggers and periodic data downloads. Since the data is acquired regularly, the team can use the data to establish a protocol for calculating productivity (i.e., carbon sequestration capacity). And because the loggers record data frequently, at one-minute intervals, they provide enough data to help the team understand the dynamics of metabolism of macroalgae. For example, the diel rhythm of macroalgae during the daytime can be understood, as well as phenomena such as deterioration in carbon removal potential due to photo-inhibition in the afternoon.<\/p>","use_case_results_title":"Plentiful data that enhances understanding of carbon sequestration capacity in seaweed habitat","use_case_solution":"<p>The team selected the HOBO Dissolved Oxygen data logger (U26-001), an affordable, high-performance monitoring device with 0.2 mg\/L accuracy, and the HOBO pH\/Temperature data logger(MX2501), featuring Bluetooth technology for easy setup, data download, and guided calibration with the free HOBOconnect app. The data loggers were deployed in two flow-through benthic incubation chambers to evaluate macroalgal primary production and carbon sequestration capacity.<\/p>","use_case_solution_title":"User-friendly, affordable data loggers for water quality monitoring "}
