Book Description
The first in situ exploration of deep-sea coral habitat in the central Aleutian Islands in 2002 confirmed expectations that had been based on fishery bycatch and research survey records which indicate corals are widespread, diverse, and abundant. This paper reports observations from analysis of video collected during 2003 and 2004 in a study area that expanded the range of earlier observations to depths beyond current fishing activities (1000 m) and encompassed the entire central Aleutian Island region. Video of the seafloor was collected at 17 sites with a manned submersible to depths of 365 m and a remotely operated vehicle to 2947 m. Corals, sponges, and other emergent epifauna were widely distributed throughout the study area and present at all depths. Changes in density and species richness were observed at depths of 400-700 m, with abundance and diversity increasing as depth decreased. The distribution of individual fishes, crabs, and octopods was examined relative to emergent epifauna: 63% of the fishes, crabs, and octopods were found in the same sampled video frames as were corals, 69% of them were found in the same frames with sponges, and 55% of them were found in the same frames with "other" emergent epifauna. Most species at depths

Book Description
Coral disease is quickly becoming a crisis to the health and management of the world’s coral reefs. There is a great interest from many in preserving coral reefs. Unfortunately, the field of epizootiology is disorganized and lacks a standard vocabulary, methods, and diagnostic techniques, and tropical marine scientists are poorly trained in wildlife pathology, veterinary medicine, and epidemiology. Diseases of Coral will help to rectify this situation.

Book Description
"Using an autonomous underwater vehicle (AUV) and towed camera system (TCS), deep-sea corals, sponges, and seafloor habitats were visually surveyed for the first time in areas of longtime trawl fishing off northern California. During an 11-day cruise aboard the R/V Point Sur 8-18 September 2014, researchers completed 6 dives with the AUV and 9 deployments of the TCS, and spent over 42 hours underwater at depths of 586-1169 meters from the Oregon- California border to the Mendocino Ridge (...) This report provides a summary of the methods and results from these underwater surveys of DSC&S off northern California. This was a collaborative effort among investigators from NOAA National Marine Fisheries Service (Southwest Fisheries Science Center, Northwest Fisheries Science Center [NWFSC], Pacific Islands Fisheries Science Center [PIFSC], and Alaska Fisheries Science Center [AFSC]) and several universities including California State University (Humboldt State University and Moss Landing Marine Laboratories), University of California Santa Cruz, and Oregon State University"--Page 1.
