Kelp monitoring involves deploying temperature and pH sensors at restoration sites, like the one off the coast of Hotham Sound, to track the growth and environmental conditions of newly out-planted kelp. These sensors, installed along the water column where the kelp grows 10 meters below the surface, record vital parameters such as ocean temperature and pH levels. Maintaining optimal conditions is crucial for kelp health, as temperature and pH significantly influence metabolic processes like photosynthesis and nutrient uptake. By collecting data every 30 minutes, this method ensures the kelp's environment remains conducive to growth and helps identify potential risks to the restoration site.

Additionally, kelp monitoring includes using Remotely Operated Vehicles (ROVs) to gather substrate data and observe local flora and fauna at the site. The ROVs, equipped with HD cameras and powerful lights, safely and efficiently collect data in areas too hazardous for human divers. This comprehensive approach provides valuable insights into how the kelp influences its surroundings, such as potential impacts on local pH and temperature through shading and metabolic processes. With this data, informed decisions can be made to support and enhance kelp restoration efforts, ensuring a healthy and sustainable marine ecosystem.
