Sub-surface Oil Traces in Gulf09/06/2010 |
| NOAA's independent analysis of water samples provided from the 22nd to 28nd May research mission of the University of South Florida's R/V Weatherbird II confirmed the presence of very low concentrations of sub-surface oil and PAHs (polycyclic aromatic hydrocarbons) at sampling depths ranging from 50 metres to 1,400 metres. |

"NOAA's analysis of the Weatherbird II samples shows that concentrations of hydrocarbons decrease with depth, with a notable exception of samples at 300 metres from Station 07, which warrants additional research attention," said Dr. Steven Murawski, chief scientists for NOAA Fisheries. "Also, PAH levels are very low in all samples, with only five of 25 having reportable concentrations of the priority pollutant PAHs."
"We are deeply concerned about what this oil spill means for the health of the Gulf of Mexico, and for the millions of people who depend on these waters for their livelihoods and enjoyment," said Dr. Lubchenco. "NOAA is using all the scientific methods at our disposal to assess the damage, from satellites in space, planes in the air, boats on the water, gliders under the sea, scientists in the field, and information online."

MCA on Surveying the British Coast |
Rob Spillard explains how the MCA is conducting hydrographic surveys, including the history of British hydrographic surveying, latest developments in technology and wreck research projects, sometimes accompanied by a BBC TV camera crew. This movie includes an example of the discovery of two sunken WWI submarines off the Orkney Islands.

The Weatherbird II samples came from three stations: 40 and 42 nautical miles to the northeast of the well head and 142 nautical miles southeast of the well head (see chart).
