4th Atmospheric Oxygen

Please join us for the 4th Workshop on Atmospheric Oxygen!

The workshop will be held as an in-person gathering August 23-25, 2023 on the campus of Bowdoin College in Brunswick, Maine (USA). It will also be possible to observe the meeting via live-stream. Details can be found below. For full consideration, please complete the free registration form no later than May 5, 2023.

We encourage participation by any scientists with an interest in atmospheric oxygen, or other species relevant to atmospheric oxygen. Instrumentation, measurements and model studies are all welcome. If you have doubts about the appropriateness of your topic for this workshop, please feel free to ask one of the organizers.

While you may view the meeting remotely via live-stream, only in-person participants will be able to present their work. We hope this encourages you to come to Maine for a lively meeting with many opportunities for unstructured interactions and spontaneous conversations. Please join us for a stimulating (and overdue) gathering.

For both in-person attendance and virtual observation, please complete the registration form no later than May 5, 2023. Late registration (May 6–August 2) is possible, but will incur a modest fee and we cannot guarantee the opportunity to present your work.

Bowdoin College, Brunswick Maine, USA. Brunswick is a walkable town of 22,000 people, with Bowdoin College located on the edge of the central business district.


Thanks to support from Bowdoin, there are no registration fees associated with this workshop. Attendees will need to cover their own travel to/from Brunswick, as well as lodging. 


The workshop will include continental breakfasts and lunches daily, as well as dinner on August 24. There will also be an excursion for participants on the afternoon of August 25. All of this is supported by Bowdoin College.


We have held blocks of rooms at the Brunswick Hotel (call to ask for the workshop rate), and also the Fairfield Inn & Suites.  If you would like to explore other options in Brunswick and beyond, some information is available here. During the meeting, we will provide a van service for attendees who are staying in Brunswick but beyond walking distance, so that a car will not be a necessity. We encourage you to make lodging reservations soon, as demand will be very high at time of year, particularly on the night of August 21.  If you need help with lodging, please contact Emily Green (egreen@bowdoin.edu).


Brunswick is located about 2.5 hours north of Boston, Massachusetts, and 35 minutes north of Portland, Maine, both of which are served by major airlines. There is frequent bus service from Boston’s Logan Airport to Portland and less-frequent service directly to Brunswick. There is also train service from Boston’s North Station to Brunswick. From Portland, there are taxi and shuttle services to Brunswick. 

Rental cars are available at the airports in Boston and Portland, as well as in Brunswick itself.
