Jeniffer Soto Perez (left) and Emily Richardson (Right) prepare water quality sample bottles onboard the RV Landsteiner during a high-resolution water quality mapping survey. The boat is equipped with a flow-through system that pumps water onto the boat while underway and directs sample water to a multiparameter water quality sonde, thermosalinograph, fluorometers, nitrate and ammonium analyzers. Discrete samples are taken throughout the day to validate and calibrate the instrument readings and provide additional water quality and phytoplankton data.
