Kelp does not put down roots in the sediments on the seafloor.  Instead, it anchors itself onto rocks.  Many organisms make these rocks their own.  The area on the San Pedro shelf called the "Rock Pile" is where the coastline used to be 10,000 years ago.  As the planet warmed and the ice sheets melted, sealevels rose, covering this rocky coastline with seawater.  
Below are some pictures of the organisms we collected during this biodredge.  All organisms were returned to the ocean.
