Evaluacion de los servicios ecosistemicos marinos en las estaciones de serie de tiempo de la red latinoamericana Antares

The project utilizes the Antares network of eight time-series stations across Latin America to study phytoplankton's role in regulating and supporting ecosystem services, such as carbon sequestration and fisheries support. By integrating in situ data from 40 sampling cruises with remote sensing and bio-geochemical modeling, the team aims to understand how climate-driven changes in the ocean environment affect these services and the coastal populations that depend on them. Initial findings indicate that fish productivity in the South Brazil Bight is likely food-limited, as potential yields based on primary production significantly exceed reported FAO catches.

• The project is analyzing data from 40 sampling cruises to examine phytoplankton taxonomy, pigment composition, nutrients, chlorophyll A, and phaeopigment to determine trends in phytoplankton populations and the ocean environment. In the Argentine Sea, the team is specifically studying the carbonate system to analyze ocean acidification.
• Bio-geochemical and physical ocean models for the period 1968-2007 were used to model nutrients (N, P, Si, Fe), phytoplankton, zooplankton, detritus, C, and O2. However, regional testing for net primary productivity revealed that available data are insufficient to constrain model parameters, necessitating more ground truthing to align modeled chlorophyll profiles with actual observations.
• In the South Brazil Bight, calculations based on a mean primary production of 188 g C/m2/yr and an idealized food chain suggest that potential fish yield is 30-60 times higher than the FAO reported catch of 0.08 MT from 1991-2000, indicating that fishery resources in this area are food-limited.
• The project identifies phytoplankton as providing two primary types of ecosystem services: regulating services, through the fixation of atmospheric CO2 and its burial in deep waters which influences climate trends, and supporting services, through photosynthesis and nutrient cycling which provide 50% of the oxygen humans breathe.
• A socio-economical team established in 2015 is investigating the socioeconomic effects of phytoplankton ecosystem services and how decision-makers perceive and react to these links, while classifying stakeholders as those who affect, are affected by, or manage the relationship between ecosystem services and human use.
