Redes de observación de la acidificación oceánica, costera y estuarina: Océano Atlántico Norte, Este y Costa del Golfo

DESPLÁCESE PARA SABER MÁS

Lo que hacemos

In this project we are developing the North Atlantic Ocean, East and Gulf Coast ocean acidification (OA) observing system in response to the requirements of the Federal Ocean Acidification Research and Monitoring (FOARAM) Act. The observing system will be used to determine patterns and trends in key geochemical indicators of ocean acidification. The observing network of the East and Gulf Coast is based on the following elements:

Mediciones de aguas superficiales mediante sistemas autónomos en seis buques de oportunidad (_SOOP-CO2).
Cruceros dedicados al carbono en el Golfo de México y la Costa Este (GOMECC) con mediciones en superficie y subsuperficie en el buque Ronald H Brown de la NOAA. Esto mejorará la comprensión a nivel de proceso de los controles sobre la acidificación de los océanos.
Amarres con instrumentos autónomos para determinar los rápidos cambios temporales y sus causas.
El desarrollo continuo del sistema de observación con nuevos instrumentos y protocolos.

The scientific component includes analysis of total alkalinity (TA), dissolved inorganic carbon (DIC), partial pressure of CO₂ (pCO₂) and pH from samples taken on the cruises and mooring efforts. Data reduction, quality control and data management of the large data sets are a critical component of the observing system. Data products and algorithms to extrapolate the OA indices in time and space are being developed as part of the effort. These cruises provide a data set of physical and chemical coastal ocean parameters that is used both for improved spatial understanding of ocean acidification and to provide a general understanding of changing patterns over time by comparison with previous cruises. The monitoring component is an essential part of the Ocean Acidification Program (OAP), providing a long-term assessment of changes of biogeochemistry and ecology in response to increasing CO₂ atmospheric levels and large-scale changes in coastal dynamics.

KEYIMPACTS

Antecedentes e impactos clave

Ocean acidification occurs as greater amounts of carbon dioxide (CO₂) from atmospheric emissions are absorbed by the oceans, lowering pH levels and making seawater more acidic. Although the ocean’s uptake of CO₂ helps to regulate atmospheric CO₂ levels, the lower pH negatively impacts a wide range of marine organisms, impairing their ability to thrive. This is causing a fundamental change in the chemistry of the ocean leading to increased acidity which impacts marine life and the people who depend on them. Dedicated SOOP-OA research cruises on the Gordon Gunter and Henry B. Bigelow along with the East Coast Ocean Acidification (ECOA) research cruises and the Gulf of America and East Coast Carbon (GOMECC) research cruises are used to obtain subsurface measurements and a comprehensive suite of biogeochemical observations. PMEL and academic partners maintain three moorings that are also an integral part of the effort.

Understanding Acidification in the Gulf of America

The long-term and comprehensive study of ocean acidification in the Gulf of America improves understanding of how coastal ecosystems respond to changes in the marine environment over time and predict how they will fare when exposed to increasing levels of acidification.

Creación de asociaciones

AOML’s Ocean Acidification Program is an integrated and focused monitoring effort developing and maintaining strong partnerships with federal, state/territory, academic and other partners across the U.S. The program collaborates with partners such as NOAA Ocean Acidification Program, NOAA Pacific Marine Environmental Laboratory, University of Miami Rosentstiel School of Marine and Atmospheric Science, University of Miami Cooperative Institute for Marine and Atmospheric Studies, and Northern Gulf Institute.

Datos críticos de alto impacto

AOML’s Ocean Acidification Program provides consistent, sustained, and long‐term measurements quantifying the increase of CO₂ in near surface coastal waters. The long-term and comprehensive study of ocean acidification in the Gulf of America and South Atlantic improves understanding of how coastal ecosystems respond to changes in the marine environment over time and predict how they will fare when exposed to increasing levels of acidification.
