REMARCO regional observatory takes up the challenge

OA Week 2021, REMARCO regional observatory takes up the challenge: reporting marine acidity in Latin America and the Caribbean


The Marine-Coastal Stressors Research Network in Latin America and the Caribbean (REMARCO) is made up of institutions from 18 Latin American and Caribbean countries, participating in the International Atomic Energy Agency (IAEA) technical cooperation project RLA/7/025 for the strengthening of coastal marine research. The project currently includes research on aspects of harmful algal blooms, eutrophication, microplastics and ocean acidification with the aim of communicating with the different actors and generating tools for decision-makers.

The main objective of the acidification component is to build capacity in the region to measure ocean acidity and report on Sustainable Development Goal (SDG) indicator 14.3.1 (pH).

To achieve this objective, the following activities are being carried out:

• Forming a working team with researchers from the 18 REMARCO countries.

• Identify the needs in the region that to date did not allow the indicator to be reported and a REMARCO plan to close the gaps.

• Establish agreements between those responsible for national reporting of the indicator and REMARCO.

• Establish a regional observatory to generate local and regional data of global interest.

• Develop standardized protocols for sampling, measurement and uncertainty estimation of total alkalinity, pHT and dissolved inorganic carbon.

• Conduct (virtual) training courses for analysts and indicator reporters.

• Deliver kits of equipment, materials and reagents for indicator reporting with the required quality.

• Strengthen regional capacities to purify m-cresol and develop working standards.

• Report indicator 14.3.1 (3 countries by 2020).

A “round table” will be held with representatives of the ocean acidification component from different REMARCO countries (Spanish, English and Portuguese languages) and a representative of IAEA. The representatives will make 5 min interventions and after each presentation a question and answer session will be opened for discussion with the audience (each question will be answered in the language in which the question is generated).

Ocean Acidification Week 2021 was sponsored by the following organizations:

(1) GOA-ON, the Global Ocean Acidification Observing Network,

(2) NOAA, the United States National Oceanic & Atmospheric Administration,

(3) IAEA OA-ICC, the International Atomic Energy Agency – Ocean Acidification International Coordination Centre, and

(4) IOC-UNESCO – the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization
