Entity_and_Attribute_Overview:
A hydraulic vibratory drilling rig mounted on an all-terrain vehicle and secured to a barge was used to advance piezometers for submarine ground-water sampling. These piezometers consisted of 2.5 cm diameter steel pipe in 3.4 m lengths that were joined by hydraulically crimped couplings. Water samples were taken general every 305 cm with water quality measurements of temperature, conductivity, dissolved oxygen, pH, and oxidation-reduction potential made using a YSI 650 Multi-Parameter data sonde. In addition, filtered samples were collected for nutrient measurements.
