“I would say possibly hundreds of thousands were killed… Sea birds are top predators,” [Heather Renner, biologist with Alaska Maritime National Wildlife Refuge] said. They have definitely let us know that there’s change going on in the ocean ecosystem”…Renner says [the birds had an] exceptionally low birthing season…It uses this injection as a marker to identify soil and sediment particles laid down at that time.Cs is analysed by directly counting the sediment in a high resolution low background germanium gamma detector.A high-power radiotelegraph transmitter was available for sending passenger "marconigrams" and for the ship's operational use.Although Titanic had advanced safety features such as watertight compartments and remotely activated watertight doors, there were not enough lifeboats to accommodate all of those aboard, due to outdated maritime safety regulations.

The distribution pattern of Cs-137, the radionuclide of main radiological significance in the Chernobyl deposition, is patchy due the uneven deposition and sediment accumulation to the bottoms.The highest amounts occur in the sediments of the Bothnian Sea and the eastern Gulf of Finland.The total inventory of Cs-137 in the Baltic Sea sediments was estimated to be about 2 280 TBq in 2010.The largest ship afloat at the time it entered service, the RMS Titanic was the second of three Olympic class ocean liners operated by the White Star Line, and was built by the Harland and Wolff shipyard in Belfast.Thomas Andrews, her architect, died in the disaster.) was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912, after colliding with an iceberg during her maiden voyage from Southampton to New York City.
