8 Nov GSW meeting will be at the Cosmos Club

It is an IN-PERSON meeting only. It will feature formal talks on the asteroid Bennu, the Juno magnetic field investigation, and What is Taphonomy, and why does it matter? We will begin with a talk by Jason Dworkin (GSFC-NASA) on ‘OSIRIS-REx delivered a sample of asteroid Bennu to Earth’. Next up will be Jack Connerney (ADNET at NASA) talking on ‘The Juno Magnetic Field Investigation: Dust from Mars, the Zodiacal Light, and a Comet Discovered in Flight’. The final talk of the evening will be presented by Anna K. Behrensmeyer (Smithsonian National Museum of Natural History) on ‘What is Taphonomy, and why does it matter?’ Abstracts of the talks, and biographies of the speakers, are here. Come at 7:30 PM to socialize and imbibe, the meeting begins at 8 PM, and ends by 10 PM.

A trip over the Fall Line (4 Nov field trip) in the Richmond area

The Itinerary and Logistics information are here. The Waiver is here. Please read and sign/date the waiver, and bring it with you. It will be collected BEFORE you can go on the field trip. You will receive a short guidebook to the field trip when you provide the signed waiver. Please note that a final go/NOgo for the trip will be based on the weather forecast by 31 Oct. So check back HERE in the first few days of Nov to see if the trip is still planned. And also note that there is a post field trip Oyster fest planned on the evening of the field trip at Mark Carter’s home in Louisa. If you are interested in attending please RSVP to Mark (mcarter[at]usgs.gov) by this weekend (Oct 29). You can camp overnight in Louisa if you don’t want to return home after the Oyster fest. Further details on all of these topics are in the Logistics. Finally, some of the trip stops require that you have waterproof boots to get close to the outcrop. So plan accordingly.

Draft minutes of 4 Oct meeting (1592nd GSW)

Our meeting secretary, Graham Lederer, has kindly provided the following draft minutes of our last meeting. Let him know of any additions or corrections at glederer[at]usgs.gov.

Talks for our upcoming virtual-only 25 Oct meeting and a SAVE THE DATE for 4 Nov field trip

The presentations will include talks by Geoffrey S. Ellis (USGS, Denver) on “Geologic hydrogen: An overlooked potential primary clean-energy resource“, Jack Conrad (NASA, Marshall Space Flight Center) on “Sampling Geologic Properties of Mars’ Crust with Secondary Crater Clusters“, and Kathryn Watts (USGS, Spokane) on “Mining the Science of the Nation’s Premier Rare Earth Element Deposit at Mountain Pass, CA“. A meeting flyer is available here. The GSW will also be having a daylong field trip on Saturday, Nov. 4, which will include a stop along the falls of the James River in downtown Richmond, VA. It will probably start around 9 AM and finish around 4 PM. Further details will follow shortly.

4 Oct GSW meeting (the 1592nd) is at the Cosmos Club

It is an IN-PERSON meeting only. It will feature talks on space weather, experimental petrology, and exploration of the planet Mercury, and of course, an informal presentation on the spectacular return of the asteroid samples from OSIRIS-REx. We will begin with a talk by Yarieska Collado-Vega (GSFC) on the ‘Moon to Mars Space Weather Analysis Office: Support for NASA missions and the Artemis program’. Next up will be Megan Mouser (Carnegie) talking on ‘Exploring early planetary formation processes using high-pressure, high-temperature experimental techniques’. The final talk of the evening will be presented by Shoshana Weider (NASA Hq) on ‘Mercury Exploration: Past, Present, and Future’. Abstracts of the talks, and biographies of the speakers, are here. This meeting has proven more difficult than most to assemble because of a possible government shutdown. So details of the talks, and even who the speakers will be, was still in a state of flux until two days before the meeting. Many of you will remember our last US government shutdown in 2019, which extended for more than a month. We had several in-person GSW meetings during that time, and I vividly remember the circumstances because I was your GSW president. It was a time of improvisation, and my favorite event was showing selected cartoons from Richard (Rick) Blakely (USGS-Emeritus) as a stress reliever. One final issue: we are having some problems accessing our archives, and so Tim Mock was unable to provide the history slide during our last meeting. That slide has been a part of the background of our meetings for as long as I have been at GSW. It seems to be a problem associated with our web server, and I am working this issue, as are several others. Everything else for the meeting should be the same: Come at 7:30 PM to socialize and imbibe, the meeting begins at 8 PM, and ends by 10 PM.

Bradley Lecture by Paul Richards (Lamont) is this coming Wednesday (13 Sep) evening at AGU (2000 Florida Av)

Traditionally, the GSW has adjourned for the summer months to provide time for fieldwork. Our named lecture, the Bradley, will restart the GSW fall season, and will be given by Paul G. Richards, of the Lamont-Doherty Earth Observatory. It will be held this year at AGU Headquarters (2000 Florida Av. NW), beginning at 8 PM on Wednesday, 13 September. Come at 7:30 PM for socializing (AGU usually has gratis snacks and drinks). The Bradley lecture, ‘Precision Seismology with applications to signals Old and New’ will be 60 minutes with questions to follow. The abstract, and biography, are here, and a flyer is here. You will be asked to sign-in when you enter the AGU building, after you tell them that you will be attending the Bradley lecture of the GSW. If you use the Metro (Red line) you’ll get off at the Dupont Circle stop, and walk north a few blocks on Connecticut to Florida Av. Take a gentle right, and AGU will be on your right in the next block. If you are interested in getting dinner beforehand in the area, the Washington Post had a nice piece last week (7 Sept) on the Square, DC’s new dining collective, located at Farragut Square. Check out the review here.

3 May 2023 GSW meeting (the 1590th) is at the Cosmos Club

and will be a Cryosphere-themed meeting. It will be an in-person meeting ONLY. We have talks about measuring our changing Cryosphere one photon at a time (Neumann, NASA GSFC), weighing the Cryosphere and monitoring its changes with the GRACE Follow-On satellite mission (Croteau, NASA GSFC), and using geophysical environmental data to support operations in Sea & Lake ice (Clark, USNIC). A flyer is here, and abstracts, bios & pics are here. The meeting will be held at the Cosmos Club (7:30 PM for socializing, 8 PM for talks. Stay tuned for further updates.
