Geotimes is a free electronic newsfeed for the geoscience community. The American Geosciences Institute coordinates and edits Geotimes, but it is the result of contributed materials from societies, geoscience organizations and others in the community. Do you have a geoscience blog or newsfeed with an RSS feed? It may be a good fit for Geotimes. To learn more about RSS or to submit information to Geotimes by email, please contact Joe Lilek at Events can also be listed on the AGI Geoscience Calendar.

By Harriet Cornachione, GSA Science Communication Intern – Ph.D. Candidate in Geology Utah State University Indiana geologists locate the southern boundary of the Laurentide ice sheet Building on the efforts of his predecessors and using new technologies to date sediments, geologist Henry Loope and his team at the Indiana Geological and Water Survey (IGS) mapped the Indiana extent of a vast glacier called the Laurentide ice sheet. At its greatest size – called the Last Glacial Maximum – the immense sheet of ice covered much of Canada and the northern United States (Figure 1). In some places the ice was about 4 km (2.5 miles) thick! Subject to episodes of advance and retreat through the Quaternary Period about 2.5 million years ago, the ice mass began its final retreat about 20,000 years ago. Today only a small remnant of the Laurentide Ice Sheet remains – the Barnes Cap in the Canadian Arctic. Studying the history of past climates, especially the glacial (cold) and interglacial (warm...

By Dorothy Merritts, Professor, Department of Earth and Environment, Franklin and Marshall College In 2014, while attending a National Science Foundation (NSF) workshop on infrastructure for Earth surface processes research at the Field Museum in Chicago, my colleague, Laurel Larsen, and I toured the museum’s “Underground Adventure” exhibit. The exhibit encouraged us to imagine shrinking to a size smaller than a penny to examine soil from a new perspective, and we did so with zest. Our underground adventure reminded me of famed soil scientist Hans Jenny’s joy when working with soil or experiencing it aesthetically through landscape paintings: “Soil appeals to my senses. I like to dig in it and work it with my hands… I like to sit on bare, sun-drenched ground and take in the fragrance of soil… In loess country, plowed fields on slopes show wide bands of attractive color gradations from dark browns to light yellows, caused by erosion of the surface soil. Warm brownish colors...

As mentioned in our previous post to the community, in recognition of their bipartisan leadership in advancing Earth and space science policy, AGU is awarding the Presidential Citation for Science and Society to Senators Cory Gardner (R-CO) and Gary Peters (D-MI). We asked both Senators to share with us what receiving the award means to them. Senator Gardner said: “It is a true honor to receive the American Geophysical Union’s Presidential Citation for my bipartisan work on science policy,” said Gardner. “Throughout my time in Congress, I have worked with colleagues on both sides of the aisle to advance important science-related policy initiatives, including landmark legislation with Senator Peters – The American Innovation and Competitiveness Act. Solutions for our most serious issues, such as climate change, will require bipartisan action and resolve, and I look forward to continuing to work with the American Geophysical Union to promote research on and tackle issues like climate...

By Chris McEntee, Executive Director/CEO, AGU and Margaret Leinen, AGU Past President and Leadership Development/Governance Committee Chair When AGU Connect launched a little over a year ago, our goal was to provide an online community for Earth and space scientists to engage in discussions and build connections. Today, we’re very pleased to announce an exciting new feature: Volunteer Central. This easy-to-use tool is intended to make volunteering with AGU even easier. Volunteer Central will make it easy to find the right opportunities for you. Once you log in to AGU Connect, all you need to do is fill out your volunteer profile and opt in to Volunteer Central. The easy-to-follow steps are included at the end of this post. Every Bit of Volunteering Helps Advance Science Volunteers are essential to AGU’s success in many ways, including providing leadership, encouraging and engaging young scientists in their work, and offering guidance and insight across a variety of projects. Whether...
