Port Aransas Oil Spill

The last news reports I've seen on the oil tanker explosion state that the oil spill has been "contained," but I couldn't find any information about how much oil had leaked prior to containment and how much of it has made it to the Port Aransas/Mustang Island coast. Is there an actual oil slick washing ashore along the beaches and jetties?

News reports are slim and none on that on our local news, some updates about the survivors and those missing.

Doesn't seem to be much leakage or we'd be hearing more about that.
