Abstract: To monitor changes in heat content and geostrophic volume transport of abyssal water accurately, 50 moored conductivity?temperature?depth (CTD) recorders used for density measurements were calibrated in situ by simultaneous ...

Abstract: data processing method to obtain high-quality data from an expendable conductivity?temperature?depth (XCTD) profiler is proposed. By adjusting the mismatch of the response time of the temperature and conductivity sensors, ...

Abstract: Eleven optode-based oxygen sensors were used for shipboard hydrographic casts in the North Pacific. Oxygen data from the optode sensors were compared with high-quality oxygen data obtained with discrete water samples, and ...

Abstract: he uncertainty of deep ocean temperature (~1°C) measurement was evaluated. The time drifts of six deep ocean standards thermometers were examined based on laboratory calibrations as performed by the manufacturer in triple ...

Abstract: We expanded the batch-to-batch offsets of The International Association for the Physical Sciences of the Oceans (IAPSO) Standard Seawater (SSW) batches P145–P163 by intercomparison measurements using salinometers. On the ...
