AGU location survey

Dear GSW members,

I hope you and yours are faring well in these difficult times.

As you know, our next GSW meeting (on March 25) is a virtual meeting using Zoom technology.

Here is a link to a short survey about the March 11 GSW meeting we held at AGU headquarters:

To complete this short survey you will need to provide your email address, but rest assured that your answer will be completely anonymized before GSW officers see the aggregate answers. Please respond by March 27.

Thank you, and hope to see you virtually on March 25!

***American Geophysical Union Headquarters***
2000 Florida Avenue NW, Washington, DC

Our next meeting in a new location, the American Geophysical Union’s headquarters at 2000 Florida Ave., NW, Washington,DC 20009. If you would like to participate in the 7pm tour of AGU’s newly-renovated LEEDS-certified, net-zero building, you must sign up in advance, with this Google form.

If you only plan to attend the 8pm meeting, then you do not need to sign up.

AGU is located at 2000 Florida Ave, N.W. AGU strongly encourages the use of public transportation and ride sharing/carpooling. The nearest metro stop is Dupont Circle, on the Red Line; we are just about 3 blocks north of the station. The most convenient parking garage is located in the Universal Building and is accessible from two points: (1) Universal North, accessed from T Street, NW, across from the side entrance of the Hilton Washington, and (2) Universal South, accessed from Florida Avenue, NW, across from the front entrance of AGU. (best access for evening activities). There is some street parking for those who are resourceful; most is metered and/or has residential restrictions. Attached is a map showing the metro & parking locations.
