“Researchers using NASA’s Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice.” Quoted from the NASA press release.
“Standard atomic weights for chemical elements have commonly been considered as constants of nature, along with the speed of light and the attraction of gravity. Hold on to your Newtonian hat and prepare for the possibility of elementary nuances.” Quoted from the USGS press release.
Mineral hardness picks are pencil-like tools that have points made from materials that match the hardness of minerals in the Mohs Hardness Scale. With them you can easily test the hardness of mineral grains in a rock and test the hardness of small-size specimens. In our opinion they are easier to use than pieces of minerals and allow you to obtain more accurate results.
“USGS hydrologic researchers have found that the movement of nitrate through groundwater to streams can take decades to occur. This long lag time means that changes in the use of nitrogen-based fertilizer — whether the change is initiation, adjustment, or cessation — may take decades to be fully observed in streams.” Quoted from the USGS press release.
Earth Science Week 2013 Toolkits are available for advance orders now! The kit contains everything you need to prepare for Earth Science Week (October 13-19, 2013), which celebrates the theme “Mapping Our World.” Quoted from the AGI announcement.
NASA’s Earth Observatory has interesting satellite images of lava flows on Tolbachik, a volcano on the Kamchatka Peninsula. The images use visible light and shortwave infrared and near-infrared to enhance the visibility of volcanic features.
The Fish and Wildlife Service has an article about how they moved a small population of endangered Columbian white-tailed deer from Julia Butler Hansen Refuge for the Columbian White-Tailed Deer to Ridgefield National Wildlife Refuge (both sites in Washington).
They needed a helicopter to get some of the deer out.
Over hundreds of thousands of years the Arctic permafrost has accumulated an enormous store of organic carbon. As it thaws from climate change the plant debris will decay and carbon dioxide and methane will be release into the atmosphere. Permafrost contains at least 4x more carbon than fossil fuel burning has produced since 1850.
“The “Great Pacific Garbage Patch”—a purported island of trash twice the size of Texas floating in the Pacific Ocean—receives a lot of media attention. [...] However, based on research we know that the name “garbage patch” is misleading and that there is no island of trash forming in the middle of the ocean.” Quoted from the NOAA Office of Response and Restoration article.

Scientific American has a new article titled “June 8, 1783: How the “Laki-eruptions” changed History”. The volcano may have been responsible for short term climate variations that caused years of crop failure in Europe.
“Statistical data update for 2012 on drilling, mining, production, shipments, sales, facilities, employment, expenditures, and reserve estimates in the U.S. uranium production industry. A new Table 10 includes uranium reserve estimates for mines and properties by status, mining method, and State.” Quoted from the Energy Information Administration website.
Researchers operating a remote control diving vehicle in the Gulf of Mexico captured several minutes of video of a rare, deep-sea oarfish – the largest bony fish in the ocean. Video on NationalGeographic.com.
