The team of USGS scientists collected stream water samples before and after rainfall events for this study. In this photo a USGS scientist is taking measurements of field parameters (dissolved oxygen, water temperature, specific conductance, and pH) from New York Branch, Iowa, at low flow (baseflow) conditions.

Looking astern, the airgun sled is in its cradle in the center of the photo. The crew are manually recovering the multichannel streamer and beginning the large figure-8 shape of coiling it on deck. Work at sea occurs 24 hours a day. In late September, there is ~12 hours of night, resulting in gear recovery at night.
