We estimated rates of production and export in the South Pacific (80°W to 180°W in a zonal band between 35°S and 50°S) using 1.5 yr of oxygen measurements from profiling floats. Export production, calculated from oxygen utilization rates below the compensation depth from December to April, was 10.7 ± 2 mmol C m −2 d −1 ( n = 36, 95% CI). The corresponding satellite net primary production was 46 ± 4 mmol C m −2 d −1 , yielding...

Both rainfall and wind have acoustic signatures that can be discerned at depths in the ocean well below the sea surface. We examine observations of rainfall and wind speed collected at a depth of 600 m in the Bay of Bengal from a specially modified Argo profiling float. In addition to the normal Argo sensors, the float carried a passive acoustic listener sensor package that monitored the spectrum of acoustic noise along the fl...
