Global Perspectives on Observing Ocean Boundary Current Systems

TLDR

Ocean boundary current systems are crucial climate components, support productive ecosystems, and impact society, prompting the development of a global observing network as part of the Global Ocean Observing System. The paper reviews boundary current system characteristics and motivations for sustained observing, and outlines next steps and recommendations for developing observing systems. The authors review current observation techniques and provide a global census of existing boundary current observing systems. The study recommends specific next steps for advancing boundary current observing systems.

Abstract

Ocean boundary current systems are key components of the climate system, are home to highly productive ecosystems, and have numerous societal impacts. Establishment of a global network of boundary current observing systems is a critical part of ongoing development of the Global Ocean Observing System. The characteristics of boundary current systems are reviewed, focusing on scientific and societal motivations for sustained observing. Techniques currently used to observe boundary current systems are reviewed, followed by a census of the current state of boundary current observing systems globally. Next steps in the development of boundary current observing systems are considered, leading to several specific recommendations.
