2nd International Workshop on Ancient Hydrocarbon Seep and Cognate Communities, June, 2019, Sapporo, Japan

Scope of the workshop
The discovery of hydrothermal vent ecosystem along the Galápagos Rift in 1977 haschanged our perception of deep water marine life. The vent ecosystem consists of large andnumerous polychaetes, mollusks, arthropods and other animals. Subsequently, similar communities
have been found around hydrocarbon seeps, sunken whale carcasses and sunken driftwood on sea
floor. It turned out that these communities depend largely upon chemosynthetic bacteria, especiallysulfur-oxidizing bacteria, for their food/energy source, and thus the communities have been called“chemosynthetic communities”.
Since the discovery of chemosynthetic communities in modern oceans, numerous
ancient chemosynthetic communities have been discovered/re-interpreted worldwide from rockformations of various ages. Majority of ancient chemosynthetic communities was found associatedwith hydrocarbon seep deposits because of their high fossilization potential related to anaerobic
oxidation of methane, which increases alkalinity and triggers precipitation of carbonate minerals.
The great advantages to study on the ancient chemosynthetic communities and theirassociated seep deposits is that the fossil record allows us to understand the evolution ofchemosynthetic communities and the spatial/temporal trajectories of seep systems are much easier
to observe than in their modern counterparts. To improve and exchange our knowledge on ancientchemosynthetic communities, the 1st International Workshop on the hydrocarbon seep and cognate
communities was held in Warsaw, Poland in 2016. The successful meeting encouraged us to haveregular meetings on the ancient seeps.
This time we meet for the 2nd International Workshop on the hydrocarbon seep and cognate
communities in Sapporo, Hokkaido, Japan. The Japanese archipelago and surrounding waters yield
numerous examples of ancient and modern seeps ranging from the Cretaceous to the Recent times.
Following the last workshop, the aims of the 2nd workshop are to exchange ideas, data and contacts
among the researchers studying chemosynthetic communities around the world. Paleontological,
geochemical and modern biological perspectives are all most welcomed.
We also prepared a 3 days pre-meeting field trip in Hokkaido Island. We will visit Morai(Miocene), Kanajirisawa in Obira Town (Cenomanian, Late Cretaceous) and Nakagawa Town
(Santonian-Campanian, Late Cretaceous). You can enjoy taking samples from those classicoutcrops.
It is noteworthy that the final stage of the upcoming book on Fossil Hydrocarbon Seeps tobe published in the Topics of Paleobiology series of Springer Verlag (editors Andrzej Kaim, Neil H.
Landman, J. Kirk Cochran) will be discussed among participating authors.
We heartily invite all paleontologists, geologists, geochemists and biologists involved in seep, ventand fall research to participate in our workshop!

with abundant alleged vestimentiferan worm tubes.
Tiny gastropods and brachiopods are present too. See
details in Hikida et al. (2003) and Jenkins and Hikida(2011), Kaim et al. (2008; 2009).

Miocene seep deposits are exposed along the cost of
the Sea of Japan. There are many colonies comprising
vesicomyid, thyasirid and solemyid bivalves. Some ofthose bivalves have drill holes made by naticid gastropods (Amano, 2003). You can obtain some more information form Ishimura et al. (2005; in Japanese).

max 20 participants. Note that the rule first come, firstserved will be applied for the field trip.

8. Travel Information
The workshop will be held at the Hokkaido University
Museum in Sapporo City, Hokkaido, Japan. The museum is located in walking distance from the Sapporo
Station (the largest station in Hokkaido). You can findmany hotels in Sapporo City.

Locality information
We will provide field trip guide book at the meeting
point. If you need some literatures before going for thetrip, please do not hesitate to contact us. We can send
you pdf files of some literature related to the sites.

Climate in June
During June, average temperatures in Sapporo range
from 13°-21°C. Mostly sunny and dry (averaged monthly rain days is 6 days), but it can be rainy.
On the other hand, temperature in Nakagawa Town, wewill visit for the field work if you applied, is much lower
than Sapporo City.

Kanajirisawa Seep (Cenomanian, LateCretaceous; Obira Town, Hokkaido)
Cenomanian seep site along the Kanajirisawa Creek.
Numerous seep carbonate bodies are exposed along
the creek and forest road. Numerous large-sized lucinid bivalves and many silicified gastropods, mostly
provannids and hokkaidoconchids, are available. The
silicified provannids are often characterized by excellent protoconch preservation (see Kaim et al. 2008 andKiel et al. 2008)!!

Finding Your Way from the JR Sapporo
Railway Station
The museum is located in the Hokkaido University
Sapporo campus about 10 minutes on foot from thenorthern entrance of the JR Sapporo Railway Station.

Yasukawa Seep (Campanian, Late
Cretaceous; Nakagawa Town, Hokkaido)

You can enter the main gate of the Hokkaido Universityand find the statue of Dr. William S. Clark. Then, you
can follow the avenue of the Poplars with the Hokkaido
University Museum (see following map).

Campanian seep site along the Abeshinai River in Nakagawa Town. There are several relatively small (lessthan 2 m wide) seep carboante bodies. Jenkins et al.
(2007) and Jenkins and Hikida (2011) interpreted thesebodies as sediments of diffusive seeps. You may findNucinella and Acharax bivalves with hokkaidoconchid
gastropods in/around the carbonate bodies.

Motor vehicles are not allowed on Hokkaido Universitygrounds, so you will need to come by bus, subway, orother public transportation.

From New Chitose Airport (Shin ChitoseAirport)

Omagari Seep (Santonian-Campanian, Late
Cretaceous; Nakagawa Town, Hokkaido)

The best way to get JR Sapporo Railway Station fromthe New Chitose Airpot is to board JR Airport Express
Train. It takes only 30 minuites from airport to Sapporo
Station.
