Comments and Feedback
No evidence of single-use gloves or facemasks during dive, despite being most common form of debris onshore.
Abundant jellyfish at site. I am new to this area, so I do knot know whether this is normal, or they are in abundance due to a lack of local natural predators (i.e. turtles).
