Introduction
The National Museum of Nature and Science (formerly National Science Museum), Tokyo
has been conducting a research project entitled “Study on Deep-Sea Fauna and Conservation of
Deep-Sea Ecosystem” since 1993. The purpose of the project is to elucidate the deep-sea faunaaround Japan and to trace anthropogenic pollutants in deep-sea animals. The investigations havebeen carried out in selected areas, and for four years in each area as one term of the project. Previous investigations were carried out in Suruga Bay on the Pacific coast of central Japan in 1993 1996,
in Tosa Bay on the Pacific coast of Shikoku Island in 1997 2001, and around Nansei Islands insouthwestern Japan in 2002 2005. The results were published in the National Science Museum
Monographs (National Science Museum, 1997; Fujita et al., 2001; Hasegawa et al., 2005). Investigations for the fourth term of the project were conducted in the Pacific coast of northern Japan
from 2005 to 2008.
The study area is dominated by the cold Oyashio Current, and also affected by the warm
Kuroshio Current. This hydrographical environment of the present study area is different fromprevious ones in this project; the previous three areas are strongly affected by the warm Kuroshio
Current. Taxonomic or faunistic surveys in this area were started around the beginning of the lastcentury. Because this area is one of the most important fishing grounds in Japan, the fauna andecology of fishery resources including pelagic and benthic fishes and crustaceans in this area havebeen frequently studied by the domestic fisheries research institutions (Kawai, 1955; Okutani and
Chinzei, 1976). Those surveys including ones with research vessels such as United States Albatross, Russian Vitjaz, Japanese Soyo-maru, Hakuho-maru, and Tansei-maru resulted in many papers on deep-sea organisms. However, no comprehensive work for the deep-sea fauna in this area
has been available to date. In this research project, deep-sea fauna and anthropogenic pollutants on
the continental shelf and slope of the Pacific coast of northern Japan, mainly off Honshu, the main
Island of Japan were studied. In this introductory paper, participants, characteristics of the study

Survey Area
The main survey area is located between 36º N and 41º N, and the bathymetric range is from150 m to 3000 m, along the Pacific coast of northern Honshu, Japan (Fig. 1). The ocean floor ofthis area is quite simple, and isobaths in general run parallel with coast line, and neither large submarine canyons nor large banks are present. The continental shelf is rather narrow; the shelf breaklies about 10 30 km from the shoreline, although it lies further, about 50 km off Sendai Bay. The
continental slope is gentle to the depth of 1500 m, and then rapidly drops to the Japan Trench, attaining 8300 m. The characteristic feature of the shelf slope area is the presence of various sizes offlat areas, which are scattered throughout the survey area (Iwabuchi, 1985).
This area is bounded by the warm Kuroshio Current and cold Oyashio Current creating complicated water mass distributions and is termed “perturbed area” or the “Kuroshio and Oyashio
confluence zone” (Hanawa and Mitsudera, 1987), or the “Kuroshio-Oyashio transition area” (Yasuda, 2003). The heat brought by the Kuroshio Current and the rich nutrient brought by the Oyashio Current make this area productive and one of the most important fishing area in Japan (Yasuda, 2003). The Kuroshio mainly comes from southward, but also from the Tsugaru Strait. The
main branch of the Kuroshio, the warm Tsushima Current, flowing northward in the Sea of Japan
enters into the studied area through the Tsugaru Strait. This complicated mixed system exists
mainly in the surface and subsurface layers, and shows temporal variability. However, the bottom
water on the continental shelf slope is dominated by the cold water of the Oyashio origin, or subarctic deep water, with a temperature generally lower than 5˚C. The hydrographic structure andvariability in this area is reviewed by Yasuda (2003). During the periods of the present survey by
R/V Wakataka-maru, the bottom temperature varied from 4˚C to 13˚C in the water shallower than
400 m while, 3˚C to 5˚C in 400 900 m in most stations (Appendix 1).
Sampling Methods
Three research vessels were employed in this study. The R/V Wakataka-maru of Fisheries
Research Agency is 57.7 m in length and 692 gross ton (Fig. 2A), the R/V Tansei-maru of the Japan Agency for Marine-Earth Science and Technology is 51.2 m in length and 610 gross tons (Fig.
2B), and R/V Soyo-maru of the Fisheries Research Agency is 67.5 m in length and 892 gross ton(Fig. 2C). Benthic animals were obtained from depths of 150 2560 m using an otter trawl, twotypes of beam trawls, a biological dredge, and a baited trap.
Otter trawl
A bottom otter trawl was carried out by the R/V Wakataka-maru. The dimensions of the otter
trawl net were 41.8 m in length, 7.8 m in width and 3 4 m in height at the mouth, with a span of 22
m between the tips of the side net, which was opened by 2.1 m x 0.9 m rectangular otter boards(Fig. 2D). The stretched mesh size of the main part of the net was 60 mm, with the finer mesh of 8mm equipped as an outer cover net at the cod end. The ground rope was equipped with steel
weights and gum bobbins of 120 150 mm in diameter. A total of 150 sampling stations were set on
the 12 latitudinal transect lines (Fig. 1). Occasionally deeper stations at 1200 and 1500 m were set

on the lines. The net was usually towed for 30 minutes on the bottom. The dates, gear, positions,depths and bottom temperatures for all stations are shown in Fig. 3 and Appendix 1.
Beam trawls
Two types of beam trawls were used during the cruises of R/Vs Tansei-maru and Soyo-maru.
During two cruises, KT 07 29 and KT 08 27, of Tansei-maru, the ORE-type beam trawl of 3 mspan was used (Fig. 4, Appendix 2). This trawl bears a pair of steel skids held by a pair of 3 m steel

beams at their upper side, with a 10 m-long double layered collecting net attached to the skids (Fig.
2E). The width and height of the fixed opening were 2.8 m and 1 m, respectively. The mesh size ofthe inner net was 4 mm square at the cod end. The beam trawl was usually towed for 30 minutes
on the bottom in each tow. During cruises of R/V Soyo-maru, a Sigsbee-Agassiz type beam trawlof 2 m span was used (Fig. 4, Appendix 3). This trawl bears a pair of steel skids held by a pair of6

2 m oak wood beams at anterior and posterior parts of the skids (Fig. 2G) and the steel skids arewider in bottom. The width and the height of the fixed opening were 2 m and 0.8 m, respectively.
The mesh size of the net was 2 cm throughout. One or two plankton nets with 0.25 mm and 0.5 mm
mesh size were occasionally equipped in both beam trawl nets to obtain minute benthic animals.
DredgeThe ORI type biological dredge was used by R/V Wakataka-maru (Appendix 1). The dredge
was modified from a naturalist dredge (Fig. 2F). The mouth opening was a rectangular steel frameof the following dimensions: 1 m in width, 0.2 m in height and 0.15 m in depth. It had a doublelayer collecting net about 1 m long. The outer net is strong, 2 cm in stretched mesh size. The inner
net had a fine, 5 mm in square mesh size.
Baited trap
The baited trap was operated by R/V Soyo-maru to collect mainly fishes and crabs (Appendix
3). The shape of the trap was truncated cone, made with a steel flame covered by 2 cm mesh net,with three entrance holes on the side (Fig. 2H). The diameter was 1.7 m at bottom and 1.2 m at top,
and the height was 1.2 m. Four plastic jars containing cut sardines as bait were placed in each cage.
Five baited trap were linked together with ropes, and sunk with anchor weight. A radio buoy wasOutline of “Research on Deep-sea Fauna and Pollutants off Pacific Coast of Northern Japan”

used to detect the position of the traps. The traps were left for one night on the sea bottom.
Sample Treatment and Depository of Specimens
Contents from each sampling gear were roughly sorted on board. Mesh sieves were used toremove animals from bottom sediments. To collect minute and easily suspended animals, sediment
samples were suspended in sea water and screened using a fine net with a mesh size of 0.25 mm.
Invertebrates were sorted and fixed by 8 10% neutralized sea water formalin or directly immersed
in 99% ethanol depending on taxa and study purposes. Most fish samples as well as specimens
used for chemical analysis of pollutants were frozen at 20˚C freezer.
The majority of specimens obtained in this survey and used for taxonomic studies are deposited in the National Museum of Nature and Science, but some specimens are deposited with theother institutions of the participants listed above, and these are indicated in papers in this volume.
