  • Ocean Acidification.
  • Eutrophication.


The acidification of the oceans produced by the alteration of the carbonate system and the decrease in the pH of the environment, as a consequence of the use of fossil fuels, has important consequences on different organisms, many of them with calcareous structures -clams, mussels, scallops, corals, crabs, sea urchins, among others. These changes can alter ecosystems and the ecosystem services that these organisms provide, putting the food security and livelihoods of millions of people at risk. Especially in coastal systems where fishing resources and recreational activities are of vital importance for local and regional economic development.

Additionally, during the last decades the phenomena of harmful algal blooms (HABs) have taken on an important connotation on the Argentine coasts due to the temporal-spatial increase, in relation to climate change and its effects on health and economic damages related mainly to fishing resources, the exploitation of bivalves and tourism. 

The discharge into the environment of toxic chemical substances produced by man has generated great concern due to the risk it implies for human health and the environment, constituting land-based sources of marine pollution. These include everyday products with industrial, agricultural, and urban applications, such as agrochemicals, heavy metals, pharmaceuticals, petroleum hydrocarbons, and a wide variety of industrial pollutants. Likewise, Persistent Organic Compounds, currently banned worldwide, constitute a continuous threat to the environment, given their high persistence, ubiquity, hydrophobicity and high affinity for microplastics.

On the other hand, although Argentina has made progress in the regulation and/or proposals for laws that allow the regulation of single-use plastics and microplastics from personal care products, the problem persists. In this sense, the presence of both macro and microplastics in different environmental compartments from coastal ecosystems of the South Atlantic has been evidenced. River ecosystems of regional importance that flow into coastal areas together with large urban settlements and different productive activities, imply the need for greater knowledge regarding the transport, presence and characteristics of plastic waste in the country.


Argentina's participation in the REMARCO network gives us the opportunity to strengthen our capacities for the study of our coastal and marine systems, based on stressors related to Global Change (acidification, eutrophication, organic and inorganic contaminants, microplastics and HABs), learn what is the impact on our coastal zones and how this can affect different ecosystem services in the study areas.

The incorporation of the IIMyC to the Regional Observatory of Ocean Acidification, the establishment of an analytical laboratory and the development of capacities for permanent monitoring, will provide information for the report of indicator 14.3.1 at the country level. On the other hand, support will be given to experimental studies on the possible effects of Ocean Acidification on key marine species as community builders and of commercial importance, which allow adaptation and mitigation strategies for society.

Until now, the factors that trigger harmful algal blooms (HABs) and the inter-annual variation of toxicity in the different microalgal species are unknown. It is for this reason that intensive monitoring has been implemented in our country in different areas of the Atlantic coast, and information is expected to be provided in order to develop early warning programs.

The first studies of microplastics and other contaminants in important marine-coastal areas such as estuaries in the Province of Buenos Aires, as well as in coastal marine areas influenced by sewage treatment plants and storm drains, will be a source of information for management plans for these socio-ecological systems.

It is essential, from a national perspective, to create action plans for a system of Observation and Monitoring of marine-coastal zones for sustainable development and protection of the coasts. In this sense, REMARCO Argentina joins the “Network of Networks” of the Pampa Azul Initiative ( Pampa Azul is an interministerial initiative (7 ministries) that seeks to advance research, development and innovation that contribute to national sovereignty and security and social, economic and environmentally sustainable development. Additionally, it is proposed to develop greater social awareness of the services and benefits provided by the sea, deploying a specific communication and scientific dissemination agenda. To this end, it has medium- and long-term planning that promotes multidisciplinary approaches and inter-institutional synergies.

Progress and Challenges

REMARCO Argentina collaborates in the formation of a national interinstitutional and interdisciplinary network in order to address the problem from different points of view. As a country, observatories will be established to measure the different indicators of SDG 14 (specifically 14.1.1a,b and 14.3.1). Nuclear tools and techniques will be used for this purpose and we will have the opportunity to cooperate with other Latin American and Caribbean countries through the intercalibration of the techniques to be developed and the possibility of using already established capacity in the country members of the network.

At the national level, we hope to be able to contribute with the national, provincial and/or municipal authorities in order to provide the tools acquired through the implementation of the project for the consolidation of national and local plans in relation to responding to SDG 14.
