Indeed, deriving millimeter-level accuracy from orbit is a stunning technical feat so it's not hard to understand why some people find such an accomplishment unbelievable.

In reality, researchers demonstrate this height measurement technique's accuracy to be within 1mm/year.

Don't be mislead by only a carefully-selected portion of the available evidence being disclosed.

In addition to the tragic toll of dead, injured, and displaced people, the earthquake and tsunamis badly damaged the Fukushima Dai-ichi nuclear power plant, eventually causing four of the six reactors there to release radiation into the atmosphere and ocean.

Mineral resources are a vital part of any economy, modern or ancient.

Since the birth of civilization, man has used these resources for pigments, metals, glasses, ceramics, cements and much more.

In June 2011, I organized the first comprehensive, international expedition to study the spread of radionuclides from Fukushima into the Pacific, and I or members of my lab have participated in several other cruises and analyzed nearly one thousand samples of water, as well as dozens of samples of sediment and biota.

In the months after Fukushima, I also formed the Center for Marine and Environmental Radioactivity, in part to help share the most accurate, up-to-date information about radiation from human and natural sources and, when it became clear that there was no coherent and consistent source of government funding to monitor radiation in U. waters and to support public education, I formed a citizen-science/crowd-funding initiative called Our Radioactive Ocean at WHOI.
