Summary of Activity and Data Gathered: Physical data holdings Ten Alvin dives from the mother ship Atlantis II were conducted in the Monterey fan valley. Two observers seats on each of these dives were occupied by a geologist and a biologist. Camera bottom-sled tows were made along 2- to 8-km long tracks during the non-dive time aboard the Atlantis II. Samples of sea-floor muds were obtained using 30-cm core tubes (up to six per dive) pushed into the bottom with one of Alvins manipulators. More consolidated sediments and rocks were sampled using the manipulator claw and biological nets. Color photographs from the bow-mounted Alvin camera and video tapes from both the bow-mounted black and white silicon-intensified target camera and the arm-mounted color camera were obtained regularly during times on bottom with Alvin. Collection of smaples of lifeforms as well as their mud substrates was made on three separate dives using Alvins manipulator. The ten Monterey Canyon Alvin dives were: 2122 10/21/88 Emory Kristof, Bill Hamner, P. Hickey 2123 10/22/88 Emory Kristof, Eugenie Clark, Paul Tibbetts 2124 10/23/88 Bill Normark, Gregor Cailliet, T.
