Greetings DMV AWG Members & Friends!
Thank you to all of our volunteers for the October Field Trips! The budding geoscientists from 4 to 9 years old loved being able to ask questions to professional experienced geoscientists! Attached is a clip from the NOAA Field Trip where the young aspiring geoscientists assisted in launching a weather balloon (we don’t currently have permission to post this on social media and we ask that you also refrain from sharing this on any social media platform)! After the launch we got to see the real-time data collection plotting on the computer screens inside the station, which demonstrated pressure changes in the atmosphere, an idea that was discussed earlier in the field trip and demonstrated through simple experiments.
WHAT: DMV AWG Social Hour and an opportunity to help shape future events for our chapter
WHERE: Wunder Garten located at 1101 1st Street NE (one block away from the NOMA Gallaudet U Metro stop on the Red Line)
WHEN: This Thursday, NOV 15th from 6-8pm
WHO: You and any geoscientist in the DMV area that would like to participate
We hope to see you Thursday!

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.
The University of Maryland’s Department of Geology hosts its inaugural Helz Lecture on October 18th, and we hope that you can join us. The Helz Lecture is a new lecture series graciously supported by Drs. George and Rosalind Helz.
Our first speaker will be Dr. Gene Likens. Dr. Likens and his team were the first to discover the regional effects of acid rain in North America. The title of the talk will be: “Acid Rain: A long and unfinished journey from discovery to political action.” Dr. Likens is a member of the National Academy of Science and is a recipient of the National Medal of Science among many other honors. In addition to his research, he also currently teaches a course in science ethics at the University of Connecticut and enjoys interacting with students.
There will be a catered reception prior to the Helz Lecture at 5 pm in the new Edward St. John Learning and Teaching Center, 2nd Floor Lounge. The lecture will begin at 5:30 pm in Edward St. John Learning and Teaching Center Room 2204. A link providing further details can be found at: https://life.umd.edu/communications/cmns/helz.html
Everyone is invited to the inaugural Helz Lecture, and it is open to the public. It should be interesting and fun. Please feel free to share widely with your students, classes, colleagues, and friends.

National Museum of Natural History, Constitution Ave. entrance
From Filter-Feeding Plesiosaurs to Miocene Megalodon (a double-header)
Curator of Paleontology, Calvert Marine Museum, Solomons, MD
I will first describe the aristonectine elasmosaur Morturneria seymourensis from the upper Maastrichtian of Seymour Island, Antarctica. The cranial anatomy of Morturneria is derived relative to all other plesiosaurs, possessing a novel suite of dental and oral cavity adaptions. It is thought that this highly derived suite of adaptations is convergent with extant gray whales and archaic mysticetes and that it functioned similarly in sieve feeding following suction. The second half of the presentation will focus on trophic interactions between Neogene cetaceans and the mega-tooth shark Carcharocles megalodon (Otodontidae). Trophic interactions between this apex Neogene marine predator and contemporary cetaceans, such as Carcharocles-bitten cetacean bone, will be reviewed
Non-Smithsonian visitors will be escorted from the Constitution Ave. entrance of the NMNH to the Q?rius theatre at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitution Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group. Parking is available in the west side parking lot of the NMNH. http://nmnh.typepad.com/paleontological_society.
