Nancy Prouty collects water samples from Nisken bottles during the Surveying Deep-sea Corals, Sponges, and Fish Habitat expedition. Over the course of the 29-day expedition aboard NOAA Ship Reuben Lasker along the California, Oregon, and Washington coasts, Nancy and Amanda Demopoulos, from the U.S. Geological Survey, collected water samples from 30 CTD casts and 30 Nisken bottle collections to characterize water column chemistry. Measurements of nutrients, pH, alkalinity, dissolved inorganic and organic carbon, and particulate organic material will provide a spatial gradient of the water column and near-bottom environmental properties that influence coral and sponge habitat.
