Project Deep Spill, Minerals Management Service, March 24, 2005:
Subject: Project "Deep Spill"
Principal Investigator: Dr. Oistein Johansen, SINTEF & Dr. Cortis Cooper, ChevronTexaco
Contracting Agency: Minerals Management Service
Description: A joint industry project (JIP) was formed between the MMS and 23 different oil companies to conduct this research. The project consisted of an experimental release of oil and gas conducted in June 2000 off the coast of Norway... at approximately 800 meters [2,625 feet] water depth. The goal was to simulate a blowout or pipeline rupture in deep water...
Troubling excerpt from the final technical report on the Deep Spill JIP – Experimental Discharges of Gas and Oil at Helland Hansen – June 2000:
The interpretation of this result is that the oil is water-extracted on its way up to the sea surface.
The rate of this extraction is dependent on the solubility of the compounds in the water, such that the most soluble compounds are dissolved first. ...
This is important information, because the water-soluble compounds are generally the most toxic ones when exposed to marine biota.
The results from these measurements show that the rising of the oil through the water column represents a kind of a “stripping” process of some of the most toxic compounds in the oil. The end result is therefore that a portion of the most toxic compounds is left in the water column. This is contrasted to a surface generated slick, where a portion the most toxic compounds merely go into evaporation rather than dissolving into the sea.
