Just a thought, but if you had an underground space on an island, would you maybe need a big sump pump to keep it dry? Could that discharge something that would feed the algae?
Good question. I'm no spelunker, but I imagine the ground somewhere down there would be permeable. Also, there might be a possibility that it would be fresh water, wouldn't there? Or saltwater.
I can't imagine pumping ocean water through any big equipment due to the corrosive nature.
All I can surmise about the algal bloom is that something is coming out those drain pipes that probably isn't ocean water.
I've archived a LOT but I don't know if I archived anon's conversations on the island. I'll have to really dig to find that info again.

From what I have observed about LSJI, it is not flat. There’s about 100’ of elevation difference between the shore line and the uppermost point...where the ultra-bogus tennis court was. So the island is not “flat” and there’s a lot of elevation to play with when drifting tunnels into hillsides. Many “entrances” are located a good hike up the hillsides from.tje shore. Area drains, catch basins and simple floor drains are all that’s needed to carry away any water infiltration out and dumped at a lower elevation.

Might be for disposal of body parts...that would cause algae growth.
