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.

The NASA/ESA Hubble Space Telescope has captured part of the wondrous Serpens Nebula, lit up by the star HBC 672. This young star casts a striking shadow — nicknamed the Bat Shadow — on the nebula behind it, revealing telltale signs of its otherwise invisible protoplanetary disc.

The National Science Foundation’s Survey of Graduate Students and Postdoctorates in Science and Engineering is conducted annually to collect information about enrollments/hiring and demographics of graduate students (master’s and doctoral students) and postdoctoral appointees. AGI’s Workforce Program analyzed the data from 2016 to investigate participation of underrepresented racial and ethnic populations in postdoctoral opportunities within the geosciences.   Twenty percent of science graduate students were from underrepresented populations, whereas only 12% of graduate students in the geosciences were from underrepresented groups. Similarly, 9% of all science postdoctorates and 8% of geoscience postdoctorates were from underrepresented populations. Outside of the representation rate of Black and African American geoscience graduate students, the representation rates of racial and ethnic underrepresented groups in the geosciences are similar to STEM-wide trends, indicating...

This blog is part of a series addressing issues further explored in GSA’s Pardee Session Women Rising: Removing Barriers and Achieving Parity in the Geosciences.  Attend the Women Rising session, 1:30 – 5:30 p.m., Monday, November 5, Sagamore Ballroom 5, Indianapolis Convention Center (ICC), Indianapolis, followed by a networking social, 5:30 – 7:00 p.m.​ by Jane Willenbring, Scripps Institution of Oceanography, University of California San Diego People seem to love superhero movies. The superhero origin story is often the same–their superpowers and unique dedication to doing good and righting injustice was borne out of hardship and tragedy. Interestingly, the evil-doers in these stories are also scarred by some horribly tragic event or circumstance. This depiction of villains (and heroes) gives the audience a feel-good experience without the unpleasant thought that some people are born bad (or good), or worse, that people are not born evil (or good), but just make certain choices...

2018 University of Maryland Geology Colloquium Series Friday, November 2nd 2018 at 3:00 pm in PLS 1130, UMD College Park Kristen Fauria Woods Hole Oceanographic Institution Submarine volcanic eruptions: why some rocks float and others sink The 2012 eruption of Havre submarine volcano was the largest submarine pyroclast-producing eruption in modern history. Most of the material from the eruption formed a > 1.2 km3 pumice raft that floated across the South Pacific for more than a year. Rafts of floating pumice spread volcanic material far from its source and are important for the dispersal of marine organisms. Here we explore how pumice get to the surface from deep submarine eruptions, why some – but not all – pumice stay afloat in rafts, and how high porosities and phase changes lead to complex behaviors. By understanding the clast-scale dynamics of pumice in water, we can better interpret deposits and understand the fate of volcanic material in the ocean.

This blog post hits some of the topics in the GSA Pardee Session “Earth as a Big Data Puzzle: Advancing the Information Frontiers in Geoscience”. The session is a mix of lightning talks and demonstrations: 1:30 – 5:30 p.m., Sunday, November 4, 2018, Poster Hall J-K, Indianapolis Convention Center. Please join us! By Leslie Hsu and Anders Noren What does your data look like? Is it a virtual pile of numbered versions of spreadsheets? Is it a collection of points, lines, and polygons on a digital map? Is it four dimensional? Was it carefully recorded into a field notebook then later digitized? Is it video footage? Model output? Sensor data? Measurements made on physical samples? 3D visualization of lidar point cloud data of the Flatirons, Boulder, Colorado – Image Credit: OpenTopography The geosciences has a stunning diversity of data types. The tools and methods for analyzing, managing, and delivering that data changes rapidly. As soon as you...

About 550 light-years away in the constellation of Cassiopeia lies IC 63, a stunning and slightly eerie nebula. Also known as the ghost of Cassiopeia, IC 63 is being shaped by radiation from a nearby unpredictably variable star, Gamma Cassiopeiae, which is slowly eroding away the ghostly cloud of dust and gas. This celestial ghost makes the perfect backdrop for the upcoming feast of All Hallow's Eve — better known as Halloween.
