    • Obsidian was socializing with many manatees in Magnolia Spring. When not interacting with other animals he would mill around near the sea wall. Once the sun was right overhead, he found a very sunny spot and surface rested for the remainder of the observation.

    • Obsidian was resting for most of the observation in Magnolia Springs, with many other animals. As the sun started to hit that area, all the animals became more active including Obsidian. He started socializing with several other manatees and continued for the rest of the visual

    • Obsidian was milling near a dock in Kings Bay. Some Eel Grass was floating on the surface and he was pulling it down and eating it. A kayak group encroached on him and he moved away from the food. Due to a language barrier it was difficult to explain the tag and how to passively observe the manatee. Once they moved on, Obsidian moved back to his original position and milled around the docks.

    • Obsidian was traveling out of a spring area towards Kings Bay. He encountered several groups of kayakers and a couple of boats which caused him to redirect his path. He finally went back into the spring and began socializing with a mom/calf pair. He stayed with the pair and they all started surface resting in the sun.

    • Obsidian was resting just outside the power plant boundary. He moved into the plant canal and milled around the boat ramp. As the tide turned, he moved to the other side of the canal and drifted with the current, resting on the surface. A team from FWC and CMARI caught him for a full health assessment. He had some cold stress lesions and had lost some weight but was determined by vet staff to be in good condition and therefore relocated to Three Sisters Springs. After being released into the spring he milled around for a while before settling in a restricted area away from swimmers.

    • Obsidian was traveling out to the west end of the power plant canal. He reached the boat fence and began traveling back east. He stopped about midway in the canal and began to rest.

    • Obsidian was bottom resting midway down the power plant canal. A mom/calf pair traveling into the canal got his attention and he followed them down to the creek in the eastern part of the canal. They went to a small creek, socializing with a couple of other manatees that were there also. He spent the rest of the observation resting in the outfall of the creek. He does show signs of cold stress. A health assessment and possible relocation is being planned.

    • Obsidian was at the East terminus of the power plant at the spring seep with another manatee. The two were interacting with each other and then Obsidian followed the other down the canal. Though it looked like he was on a fast track out, a mom calf pair passed him in the opposite direction and he u-turned to follow them a little way back into the canal. He engaged with them briefly before returning to his travels. He went about a mile down the canal before turning around which again seemed to be in response to another manatee coming into the canal. Obsidian joined the newcomer at another small spring then they parted ways. Obsidian continued west for another .25 mile, he remained out there for 20-30 minutes before moving back into the canal, this time at a more leisurely pace. He found a very sunny spot and began to surface rest. His respirations were 5-7 minutes apart based on his activity level. He does appear to have some marks that look like prop marks and the start of some cold stress. This canal does not have a supplemental heat source, so he will be monitored extra closely.

    • Obsidian was interacting with another manatee in the power plant discharge canal until that manatee moved further down the canal. Obsidian milled around the canal for a bit before starting to bottom rest. A mom/ calf pair moved down to where he was, and he followed them to the spring seep. He moved in and around the seep before bottom resting again. His respirations were every 5 minutes when active and every 9 when resting.

    • Since his release, Obsidian has made his way out of Crystal River and to the power plant discharge canal. Having secured access to the area, it is now possible to get a visual on him. He was bottom resting about 500ft down the canal where the water temp was 19.5. He followed two other manatees a little further down the canal, broke off from them to follow a different manatee back towards the start of the canal, where the water temp was 21. He stayed in this area exploring the perimeter, stopping in a spring seep, flowing into the canal. He would occasionally move out to the center, engage with the manatees there, then go back to the seep. He did not appear to have any signs of cold stress

    • Obsidian was released into the spring at Crystal River. He made his way to the entrance then turned around and came back into the spring. He met up with Sriracho and Slate as they were released and the three explored the spring. Though he would occasionally swim close to snorkelers he did not approach them.
