Investigation into the upstream origin of a newly recognized component of the Atlantic Ocean’s circulation requires high-resolution model.
IDIES affiliate Thomas Haine and colleagues describe their work in determining the water mass’s upstream origin, temperature, and salinity in their recent paper “The East Greenland Spill Jet as an important component of the Atlantic Meridional Overturning Circulation”. Haine, his postdoc Inga Koszalka, and collaborator Marcello Magaldi used the Data-Scope analysis cluster to take on the data-intensive calculations that their high-resolution ocean circulation model requires. In their paper, published in Deep Sea Research Part I: Oceanographic Research Papers, they present the results: the different water-mass sources and mixing history in the ocean’s circulation east of Greenland.
Their publication highlights a previously unrecognised component of ocean circulation that will contribute to our understanding of ocean circulation and its role in climate.
