Short summary
This paper describes a near-surface ocean profiler (NSOP) that is deployed from a research vessel. The NSOP is used to sample the top 10 m of the ocean and pumps water back to the research ship for scientific analyses such as for trace gases. The precision in the depth of the seawater collection improves upon previous methods. The NSOP has been used to observe vertical gradients in the upper 5 m for temperature, carbon dioxide and dimethylsulfide.
