Routine metabolic rate (RMR) and critical partial pressure (Pcrit) measurements of Salpa fusiformis collected aboard R/V Atlantic Explorer cruise AE2306 in the Sargasso Sea in March 2023

A Pryoscience Firesting optode and oxygen sensor spots were used to collect routine metabolic rate (RMR) and critical oxygen partial pressure (Pcrit).

Understanding the drivers of metabolic sensitivity is critical as climate change is shifting the distributions of temperature- and oxygen-limited organisms. Given salps’ key role in carbon cycling, it’s crucial to understand how these changes affect them across different temperature and oxygen concentrations.
