"Trawl and conductivity-temperature-depth (CTD) testing operations were conducted at various Shakedown sites near the island of Oahu. The calibration of the Simrad EK60 echosounder's transducers was performed at Kealakekua Bay. Oceanographic operations consisted of CTD casts to 1000 m at Shakedown sites and at predetermined stations along a transect line along the 158°W meridian (Fig. 1). Water samples were collected at predetermined stations using Niskin bottles for later laboratory analysis of chlorophyll a and chloropigments. Bioacoustic backscatter and currents were continuously monitored during the entire cruise. Bottom Camera (BotCam) operations were performed at predetermined stations near Penguin Bank (Fig. 1)"--Type of operation.
