New GO-SHIP samples arrived from tropical North Pacific\u00a0\u00a0<\/strong><\/p>\n

A new batch of seawater samples has arrived at NOSAMS from the recently completed Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) expedition along the P04E transect<\/a> in the tropical North Pacific.<\/p>\n

NOSAMS was founded in part to spearhead the analysis of \u039414<\/sup>C dissolved inorganic carbon (DIC) from repeat hydrography cruises. The data, archived\u00a0in the publicly accessible CLIVAR and Carbon Hydrographic Data Office database (CCHDO<\/a>) have become an invaluable resource for tracking circulation, ventilation, and changes in the global carbon cycle over time.<\/p>\n

The P04E line was last occupied in 1989. Revisiting this transect more than three decades later provides an opportunity to compare radiocarbon distributions across a full generation of ocean change, offering new insights into how the tropical North Pacific has evolved since the late 20th century.<\/p>\n

We look forward to adding these new measurements to the long-term GO-SHIP record and continuing to support the global oceanographic community with high quality radiocarbon data.<\/p>\n
