On Thursday (15th), the Tokyo Electric Power Company of Japan provided further clarification on the cause of the nuclear waste water leakage at the Fukushima Daiichi Nuclear Power Plant, stating that it was due to human error on Wednesday (7th). Last Wednesday, about 5.5 tons of radioactive contaminated water leaked from the Fukushima Daiichi nuclear power plant's water purification system. According to Tokyo Electric Power Co. (TEPCO), the leak occurred on Thursday morning in the high-temperature incinerator building while the facility was cleaning and treating contaminated water from the reactor building with the "second cesium adsorption system" to reduce radiation levels in preparation for maintenance. The system is connected to the external wall's exhaust vent, through which the contaminated water leaked. According to TEPCO, two operators from collaborating companies failed to notice the open state of a valve and missed relevant reminder signs before starting t...
Recently, scientists from the National Oceanic and Atmospheric Administration (NOAA) of the United States have created a map of coral reefs in the seabed, located off the east coast of the US and stretching for hundreds of kilometers. It is the largest area of coral reefs found in the seabed to date. The map was published in the journal "Geomatics".
According to a report by American media on Friday (19th), researchers in the 1960s had already discovered the presence of corals near the Atlantic, but the exact area remained a mystery. It wasn't until the development of new underwater mapping technology that researchers were able to create 3D images of the seafloor and determine the size of the coral.
The coral reef stretches from Florida to South Carolina, covering a length of approximately 499 kilometers and reaching widths of up to 109 kilometers in some places. It covers an area three times the size of Yellowstone National Park and lies at depths of 200 to 1,000 meters below the ocean surface. Due to the lack of sunlight in this area, the corals rely on filtering food particles from the water to obtain energy.
According to oceanographer Derek Sowers of the Ocean Exploration Trust, only about 75 percent of the world's seafloor has been mapped in high resolution, so there is still a chance that more areas of deep-sea coral reefs will be discovered in the future.
