Stepping off the edge

We have seen several shipwrecks in our years of diving. Most of them purposefully left underwater for coral growth.

Twenty five years ago marine biologists sunk cement blocks and a boat to grow coral here in Cozumel.

The cement blocks were teeming with so many different types of coral and sponges. You can see barrel, vase, rope and fan sponges covering the blocks in the pictures below.

With climate change and the warming of the oceans, agricultural runoff and pollution damaging coral reefs all over the world it’s encouraging to see it being regenerated like this.
