Abstracts Submission

On behalf of the Program Committee, we invite you to submit an abstract for presentation at the 5th International Symposium on the Ocean in a High-CO2 World. This Symposium is a gathering of the world’s leading experts in a rapidly developing frontier of research dealing with the science of ocean acidification.


This is the first time the Symposium will be held in South América will highlight the importance of ocean acidification for the region. The symposia typically attract over 400 participants and are prime networking events, bringing together researchers, students, and government and industry representatives.




Authors are invited to submit 300 word abstracts for possible inclusion in the Symposium program. Abstracts selected for both oral presentations and posters will be made available online.


Abstract Format


Abstracts must be submitted electronically through the online registration system (http://5HOCO2_abstracts.org, and must follow the abstract template.

Use the .doc template (MS Word or compatible) to prepare your abstract.


Bold, 12 point Arial font, centre alignment, capitalise main words.


12 point Arial font, fully justified. A line should be placed between the title and authors. Full names of authors should be listed and middle initials provided if applicable, underline the presenting author’s name.

Author affiliations should be numbered and shown in superscript after the last name of each author. Numbers should be separated by commas when there is more than one affiliation. Each affiliation should appear on a separate line and be numbered. Double space between author affiliations and abstract text.

Abstract Text

12 point Arial font, justified. Abstract text should be limited to 300 words (including the sub-headings but excluding the title, authors and author affiliations).






Key words

Maximum 5 keywords

Review Process & Acceptance

The International Scientific Committee will review all submitted abstracts.

As there are limited places for oral presentations some abstracts submitted for oral presentation will be considered for a poster. Authors in these cases will be advised and asked to confirm whether they wish to present a poster.


Presentation formats:


Oral Presentation


We anticipate oral presentations will be allocated 15 minutes, which includes 3 minutes for question time. Oral presentation will be organized by themes & sessions, so please identify which theme and session best fits your presentation when submitting your abstract. Results will be notified by Abril 7, 2020. If your abstract is accepted but cannot be accommodated as an oral presentation, the 5th OHCO2Symposium may offer you the opportunity to present a speed talk or poster.


All presentations in Microsoft PowerPoint (PPT) format must be submitted to the Registration desk on-site at least 1 day before your scheduled talk. If you are scheduled to deliver a talk on the first day, i.e. 7 September 2020 (Monday), you should submit your presentation upon your arrival at the Registration desk. The 5th OHCO2 Symposium will not accept uploaded presentation on the day of your talk nor in the conference halls. Please bring your presentation saved onto a USB drive. A technician will be there to assist you, if needed. To ensure your presentation is uploaded to the correct session, please name your file as Session No._Presentation Date_Full Name.


You can also submit your presentation via E-mail (please send it to: michelle@highco2-Lima.org) before the 5th HOCO2 Symposium. If you do so, please bring a copy of your presentation to the Registration desk on-site or email: michelle@highco2-Lima.org to confirm we have received it. The presenter is ultimately responsible for their talk being available on-site.


Poster Presentation Format


Posters will be A0 size in portrait orientation (84.1cm wide x 118.9cm high) (33.11 x 46.81 inches).

Posters will be displayed in themed groups for the duration of the symposium in the same room as the catering.


There will be dedicated poster sessions held following the oral presentations on two days. Each presenter will be allocated one of the sessions to attend their poster and discuss it with delegates. A PDF of each poster will also be included in the Symposium app.


Posters that do not follow above instructions will NOT be accepted for presentation. There will be two dedicated poster sessions with beverages, which are 17:00-19.00, 7 and 8 September 2020, in the Principal Room of the Maria Angola Convention Center. Presenting authors must remain at their poster during the assigned session.


Themes & Sessions


A. Organism responses to Ocean Acidification
(migration, tolerance, death, acclimation and adaptation)

1. Tolerance versus vulnerability: from species to populations

2. Acclimation and adaptation, e.g. plasticity, heritability, microevolution

3. Linking biological scales: physiology to populations

4. Mechanisms of calcification and dissolution

5. What does the paleo record tell us?


B. Ecological effects of Ocean Acidification

6. From local to global: linking process studies and observations, e.g. meta-analysis

7. Biogeographical responses to Ocean Acidification and climate change (resilience,

    changes in biodiversity patterns at regional and global scales, refugia)

8. Insights from natural Ocean Acidification analogues estuaries, upwelling regions & CO2


9. Present and future impacts on food webs and energy flow through ecosystems

10. Community and ecosystem responses, including regional comparisons


C. Changing carbonate chemistry of the Ocean

11. Paleo to present indicators of ocean acidification (paleo proxies and modeling)

12. Changing biogeochemistry from coasts to the open ocean

13. Projected changes in the carbonate system and biogeochemical feedbacks on Ocean

     Acidification (DMS, trace metals, and nutrient cycling)

14. Utilizing biogeochemical tracers to understand carbonate chemistry and ecosystem

     responses, e.g. calcification, dissolution, de-oxygenation


D. Advances in Ocean Acidification research and monitoring

15. Novel sensors and platforms for the detection of ocean acidification and  acidification  impacts

16. Designing and implementation of manipulation experiments, e.g. FOCE

17. Present and future international (co-ordination) programs, e.g. GOA-ON


E. Ocean Acidification and society – from mitigation to food security

18. Impacts and risks to fisheries, aquaculture and food security

19. Economic and societal impacts global to local

20. Adapting human communities, economies, industries

21. Managing ecosystems for Ocean Acidification (e.g. MPAs, harvesting)

22. Global to regional actions and policy for Ocean Acidification, e.g. research-policy

     networks, communication and outreach
