Dear all,
I'm doing a research on coral reefs. Now I have about 4-5 locations, with in total about 25 transects to survey. These transects will be fixed during my research. I'd like to mark the starting points of my transects with something like a small U/W buoy. However as there are many other (recreational) divers in my area, I can't use any surface markers or fancy things as this will attract other divers and they might remove my marker.
So a couple of questions here:
- Is there anybody with experience with this?
- Will it be a good idea to use for example small (500 mL) plastic bottles, attached to a 2-3 m line (in ~10m deep water)?
- How to attach such a line to the (coral) substrate, without using any concrete structures?
Your help is much appreciated!
