The NTSB investigators boarded the ship Tuesday night and again today.
One piece of information that is concerning is that some of those containers have hazardous materials.
Some are in the water. Some are open.
Investigators say there is a sheen on the water.
Materials like lithium batteries and other hazardous waste have since spilled into the water.
The NTSB says it doesn't know what those hazardous materials are, but the state and federal authorities are working to identify them and take care of them.
But right now, there is no timeline for when it will get cleaned up.
The investigators say they've also recovered the voyage data recorder, or VDR, on the Dali.
It has the data leading up to the crash.
In it, we learned the ship was on its way out of the harbor at one-twenty-four Tuesday morning.
In less than a minute, alarms were sounding.
