Following on from the previous postponement of the symposium and the 'bite-size' online event in May 2021.

The GTWS event in May 2022 will be a hybrid event. This means that symposium participants will be able to either attend in-person (participating in everything) or attend remotely (participating in certain aspects).
For clarity, and to aid participants’ choice between remote vs. in-person attendance, below are our plans for remote and in-person participants.
Remote access ticket:

  • Access to three live sessions (the afternoon session on each day of the meeting), including the Q&As after each talk
  • Access to a recording of the three live sessions (in case time zones differences make live attendance challenging)
  • Opportunity to apply to give a talk or poster remotely
  • All remote talks will be pre-recorded, with an opportunity for live Q&A afterwards (as was the case during the bitesize symposium in 2021.

In-person ticket:

  • Access to all elements of the meeting
  • Ability to interact with the remote participants 

Conference Proceedings

A decision on whether to continue the tradition of publishing the proceedings from the GTWS symposium will be made by the GTWS Scientific Committee during the meeting.  Please make your views known to this committee on whether you might wish to publish in any proceedings in the meantime by emailing

About GTWS

The Gas Transfer at Water Surfaces (GTWS) meeting occurs every 5 years and brings together approximately 150 scientists from countries all over the world. This topic is globally-important - the most widely-known example of air-water gas transfer is the ocean’s uptake of ~30% of the atmospheric carbon dioxide resulting from fossil fuel burning. The ocean’s absorption of carbon dioxide has slowed the impact of anthropogenic climate change, but is also causing ocean acidification and negatively impacting the marine ecosystem.

Plymouth is a global centre of excellence for the marine sector, with a cluster of specialist marine businesses linked to a strong advanced manufacturing sector and world-class research expertise.

The European Space Agency (ESA)The Ocean Carbon Biogeochemistry (OCB) program and Surface Ocean - Lower Atmosphere Study (SOLAS) have kindly agreed to provide financial support to help support Early Career Scientists and to promote women in science. 

The focus is on the physicochemical and biogeochemical processes that govern atmosphere-water gas exchange and fluxes, which include turbulence, shear,  breaking waves, bubbles and natural and anthropogenic surfactants. Biological and chemical processes within the microlayer can also impact on gas fluxes. Many of these mechanisms also govern the exchange of heat and momentum and thus the conference is attended by many in the community studying a wide range of processes that occur across gas-water boundaries or within the near-surface layers close to those boundaries. The scope of the conference covers all domains where atmosphere and water meet, which include but are not limited to, fresh water, estuarine, mountain, glacial, marine (coastal and open ocean) and polar regions.

Topics include: field observations, laboratory and numerical studies, near-surface processes, biological effects including surfactants, the micro-layer, remote sensing, global scale processes and many more.

Working towards a more sustainable symposium

As environmentally focussed scientists we are acutely aware of the anthropogenic pressures on our environment and climate. We, the local organising committee of the 8th International Symposium on Gas Transfer at Water Surfaces, are intending to organize a more sustainable symposium by limiting the event’s carbon and overall environmental footprint. 

Limiting emissions from waste

Waste production, water and energy use will be reduced or avoided wherever possible, such as concerning single use plastics. Materials will be reused or sorted and recycled. Recycling bins are provided throughout the laboratory. 
Reducing travel related carbon emissions

Reduced UK train fare tickets have been made available for travel within the GWR network in the UK. The symposium venue is in walking distance of the City Centre, the waterfront, train and bus station and the event’s social venues. For those with a requirement to travel by taxi, hybrid taxis are available in the city.  

Limiting printing and paper related carbon emissions

The programme and symposium materials will not be printed; they will be downloaded onto re-usable pen-drives that can be handed back at the end of the symposium for use at future meetings. 

Limiting emissions from food production

All lunches provided at Plymouth Marine Laboratory will be vegetarian and will include some vegan items. The conference dinner will have vegetarian, vegan or meat menu options.                                                                                                                                                      

Limiting emissions from future symposiums

There will be an open discussion during the symposium to discuss the approach for the next symposium to ensure its future sustainability in relation to the carbon and the environment.
For any questions or suggestions please email:  

Visa Information

Please note it is the delegates own responsibility to check their own visa requirements to attend the symposium and complete their visa application if applicable.  Visa requirements can be checked here:

Please email Geri Browne at if you need an invitation letter provided for your visa application, ensuring you list all the details you need to include in your invitation letter.

Travel and Accommodation

** Please note: you may experience issues booking train travel through with a non-UK based credit card, it is advised to use the Trainline website as an alternative **

GTWS has secured a block booking of 40 rooms at the Crowne Plaza Hotel, Plymouth (, at a cost of £120 per person, per night at a Bed & Breakfast rate.

These are held until 28th Feb 2022 when the allocation gets “washed” to 20 rooms (if not already booked!)  The final cut-off for the rooms held is 21st March 2022 when we cannot guarantee that the rooms will be available, or at the rate published.

You will receive details on how to secure this room rate in your booking receipt for the symposium.

Cancellation policy:
Free cancellation for delegates applies up until 28 days prior to the event.
Non-arrivals and early departures will be charged duration of their stay.
If the event was to cancel due to Covid-19 or the delegate has to isolate then this would be free cancellation, otherwise there would free cancellation up to 28 days prior to the event

Poster printing

If you are bringing a poster to the Symposium you may wish to use one of the poster printing services below. Please ensure posters are printed no larger than A0 and in portrait orientation. - A printing company based in Plymouth, UK. - Offers the ability to print on fabric so it can be packed in your luggage rather than as a separate poster tube.
