2. Language
Any communication, documents and presentation should be in English.

3. Scientific Sessions (I, II, III and IV)
The Scientific Session is divided into two large categories: “I and II Interdisciplinary Radiolarian Science” and “III andIV Radiolarian Studies.” All of these sessions (I, II, III and IV) are undoubtedly for radiolarian topics, and the first I andII sessions are prepared to let non-radiolarian specialists know how attractive our studies are. As non-radiolarianspecialists may attend in I and II sessions only, we prepare two registration types: “Registration Type Symposium” and“Registration Type ALL.” Anyone who plan to attend Sessions III and/or IV (Radiolarian Studies) should register on“Registration Type ALL.” We provide five special sessions for I and II symposium (Interdisciplinary Radiolarian Science)
as below:a) I. & II. Interdisciplinary Radiolarian Science (Conveners)(1) Forms: An Interface between Function and Evolution (Yuki TOKUDA, and others)(2) Biology and Paleobiology of Shelled Protista (Katsunori KIMOTO, and others)(3) Cenozoic Paleoceanography of Marginal Seas (Takuya ITAKI, Yusuke OKAZAKI, Richard JORDAN, andothers)(4) Paleoceanography of Tethys and Panthalassa (Satoshi TAKAHASHI, and others)7(5) Jurassic/Cretaceous Boundary (Atsushi MATSUOKA and Gang LI)b) III. & IV. Radiolarian Studies
We don’t provide specified session names to “III & IV Radiolarian Studies” in this 2nd circular for proposal of
most suitable names. We are asking for everyone to answer the queries on the website when you submit yourabstract.

4. Abstract, oral and poster
Due to the limited session time, the following rules will be applied for whoever is willing to have presentations, except
for our request.

a) Number of orals, choice of oral or poster one:a-1) One talk and one poster by each first author.
a-2) You can submit one abstract for each.
a-3) If oral request exceeds over capacity, InterRad XV OCM will move your oral request to poster. Only in thiscase, two posters are allowable.

b) Abstract formatb-1) The format available from the following website.
http://interrad2017.random-walk.org/InterRadXV_format.docxc) Size of posterc-1) Width 80 cm and height 165 cm. A0 size is no problem. We prepare pushpins.
c-2) As conference places are different on 23 and 24 Oct. (the Library Hall of Niigata University) and on 26 and27 Oct. (TOKIMATE near JR Niigata Sta.), you need to peel your poster off on 24th evening and put it ona panel again on 26th morning by yourself.
c-3) We estimate large number of posters due to small number of possible oral talks, so poster session time isplanned one hour in days 23rd, 24th, 26th, and 27th, respectively.

d) Oral presentationd-1) 15 minutes for your talk and additional 5 minutes for comments and questions (except for our requests).
MUST KEEP TIME!
d-2) Anybody must bring your own laptop computer (both Win or Mac acceptable) or connectable tablet (e.g.
iPad), and connect it to the display cable by yourself in the break time before your turn. InterRad XV OCM
does not prepare computers for your talk, avoiding from virus threats as well as uncontrollable problems. If
you don’t bring such device in the conference room, please find someone’s one by yourself.
d-3) Projector is for “4:3” screen but “16:9” screen.
d-4) We prepare two cable switchers (three or four computers can be connected at once) with VGA D-Sub 15
pins connector. If your device does not have this kind of connector, please prepare conversion adapter to
VGA D-sub 15 pins.

5. WiFi access8

Free WiFi both in the Library Hall (23 and 24 Oct.) and in TOKIMATE (26 and 27 Oct.) are available after yourregistration on site. Free WiFi is available in our recommended hotel.

6. Proceedings
Proceedings for InterRad XV in Niigata 2017 will be issued for these journals. Details will be explained in the 3rd
circulara) Island Arcb) Revue de Micropaléontologiec) Paleontological Researchd) Bulletin of the Geological Survey of Japan

In a current situation, the deadline of submission is decided to Island Arc only by 1 November 2017.
We critically review any manuscripts following the required acceptance quality in journals, and your manuscript may
not be issued on your expected journal. We will prepare questionnaires on the website about which journal you wish to
submit your manuscript.

7. Excursions
We plan two pre-conference excursions (Excursion A (Boso), Excursion B (Inuyama)), two mid-day excursions(Excursion C (Itoigawa), Excursion D (Tai’nai)), and one post-conference excursion (Excursion E (Okinawa)) as
conference options. Details are shown on Supplement B. We don’t accept the request to attend excursion only. As
surplus subscription to the allowable participants’ numbers is predicted for any excursions, anyone should be registeredas quick as possible.
As for Excursion E (Okinawa), there are several limitations and required rules. In further, we could manage to arrange
one chance in Excursion E for sampling and one day only for observation of radiolarians. In addition, less than 12
people can go on board due to boat capacity. If you hope to attend plankton sampling tour in more flexible schedule,
we recommend to attend our annual tour on early winter (late November or early December in general) (not planned in2017), rather than this excursion. We will notice it for those who give up in this time.

The hotel recommended will be introduced on our website. It is noted that the accommodation fee is estimated byeach person but not each room. If you book a room for two persons, you need to pay twice the price. Our recommended
hotel is next to both “TOKIMATE” where we have ‘Radiolarian Studies’ sessions (Session III and IV, on 26 Oct. and 27
Oct.) and “Cafe Audrey” where we have the ice break party. The benefit of this hotel is direct connection to JR Niigata
Station, free Internet connection (WiFi), English available, breakfast, and comfortable. The service bus for our InterRad
XV in Niigata leaves and arrives near this hotel. We strongly ask everyone to book this hotel on OUR website.
If Halal, vegetarian, allergen free, and other special meals are needed, please contact to our travel agent (contact
address shown on the web). However, we are afraid but we cannot prepare such special meals in any parties (a: ice
break; b: welcome party; c: farewell party) and all meals in all excursions.

10. Websites for your registration, payment, accommodation, abstract submission
The on-line system “AMARYS” will open from the early April 2017 for registration (incl. welcome party), abstract
submission, information on accommodation (incl. breakfast; not incl. lunch and dinner), choice of options (ice break
party, farewell party, Excursion A through Excursion E), and payment. Payment may be separated in “registration”,“accommodation”, and “options.”
In AMARYS, the Japanese Yen Currency by Credit Card is only acceptable. However, those who wish overseas
remittance etc., please ask our travel agent (shown on AMARYS).

11. VISA, Invitation letter or other documents for your visit to Japan
Please ask us after you registered on the website.

12. Money exchange and credit cards
Several restaurants and small shops can be paid by cash only in Niigata and other sites in the Excursions. As you
have a small opportunity to go bank during the conference (bank opens from 9:00 to 15:00 on weekday), we recommend
to exchange money in airports [money exchange unavailable in the hotel]. Cash may be drawn in “convenience stores”(the 7-Eleven, the Family Mart, the Lawson, etc.) with your credit card. There are many convenience stores, “Kon-Bini”
in Japanese, everywhere. VISA, MasterCard and JCB are useful than American Express. China Union Pay card is
acceptable in several shops.

Excursion A (Boso)
Cenozoic Biostratigraphy, Chronostratigraphy andPaleooceanography in the Boso Peninsula and BANDAISANGEOPARK in the Aizu Region, East Japan
Contacts: Isao MOTOYAMA ( i-motoyama@sci.kj.yamagata-u.ac.jp ), Takuya ITAKI, Shin’ichi KAMIKURI,
Yojiro TAKETANI, Makoto OKADA
Price: 65,000JPY/person
Allowable participants: Min 10, Max 20

Excursion A provides a rare opportunity to look through the geologic history of accretionary processes andsedimentation in the slope basins from the early Miocene to the Pleistocene, with a hopeful candidate to the Global
Boundary Stratotype Section and Point (GSSP) for the lower and middle parts of the Pleistocene Stage. In the first day,the trip starts from the GSSP candidate at the Tabuchi section along the Yoro Valley where radiolarian biostratigraphy
is examined by Itaki (Stop 1). The middle to upper Miocene Amatsu Formation (Stop 2) is key strata to directly correlate
between tropical radiolarian zones (RN5 to RN9) and Northwest Pacific zones (Eucyrtidium inflatum to L. rendodoensisS. acquilonium zones) (Sawada et al. 2009, Jour. Geol. Soc. Japan, 115). In contrast to these sediments deposited in
the fore-arc basin, the Hota Group is significantly deformed by effect of accretionary process (Stop 3). The geologic
structure in this group was reconstructed based on radiolarian fossils collected from >100 localities (Saito 1992, Contr.
Inst. Geol. Pal., Tohoku Univ. no. 93). The Chikura Group (Stops 4, 5) is interesting because of gravity flow deposits
and the occurrence of cold-seep clams which take energy from hydrogen sulfide or methane. In the 2nd day, we willvisit raised coastal terraces named as ‘Genroku Terrance’ (1703 Genroku earthquake; M 8.2) and ‘Taisho Bench’(suddenly uplifted at 1923 Great Kanto earthquake; M7.9–8.2) (Stop 7). In the 3rd day, we will look Mt. Bandaisan, an
active volcano, and enjoy BANDAISAN GEOPARK on the morning (Stop 8). After it, we go to JR Niigata Station.

The OK Tuff, coded as Am 78 Tuff in the upper Amatsu Formtionin this area. This is an important key bed as a well known widespread tephra.

Triassic to Jurassic Radiolarian Events in the Panthalassa
Ocean Recorded in the Mino Accretionary Complexes
Contacts: Tetsuji ONOUE (mailto: onoue@sci.kumamoto-u.ac.jp), Rie S. HORI, Satoru KOJIMA
Price: 49,000JPY/person
Allowable participants: Min 15, Max 20
This trip will focus on radiolarian response to global catastrophic events (such as bolide impact, large volcanism andanoxia) recorded in the Triassic to Jurassic radiolarian chert from the Mino accretionary complexes, central Japan. The
radiolarian chert of the Mino accretionary complexes records the sedimentary history on an oceanic plate in thePanthalassa Ocean prior to accretion at the trench. The following topics will be presented and discussed in the field:·End-Permian mass extinction.
·Early Triassic anoxia and its subsequent recovery in the Middle
Triassic.
·Paleoenvironmental changes across the Early/Late Carnianboundary (the Carnian pluvial event).
·Collapse of marine ecosystem triggered by a Norian impact event.
·Ocean acidification at the Triassic/Jurassic boundary.
·Early Jurassic (Toarcian) anoxia and the formation of black shale.

In addition to these topics, this trip will include aspects of the accretion
process of oceanic plate sediments during the Middle to Upper Jurassic.
The excursion will start from Nagoya and will end in Niigata near the
conference place.

Magana Museum. Large limestone masses, Mt. Myojo, is exposed in the Kotakigawa Jade Gorge Geosite. The Fossa
Magna Museum, renewed in March 2016, displays several exhibits, such as jade and Dr. H. E. Naumann known as a
discoverer of the Fossa Magna. In the former geosite, we also admire the tinted autumn foliage, which leaves turn color
from green to brilliant scarlets and golds.
In the afternoon, we visit the TsubameSanjo Regional Industries Promotion Center, located near JR TsubameSanjo
Station in Sanjo City. Sanjo City and neighbor Tsubame City are the top metalware production area in Japan. The
Tsubame industry deals mainly with spoon and fork using hand-hammered copperware skill. In addition, stainless steel
pots and kettles are also produced in this area by using the artisanal skill. The Sanjo industry products mainly kitchen
knives using traditional smithing skill. The center sells special products made by Tsubame and Sanjo cities.

Price: 80,000JPY/person
Allowable participants: Min 15, Max 19
Notes: This excursion will end at Okinawa/Naha Airport (OKA) in 1st/Nov (carefully read ALL thedocuments).

In this trip, we will visit the Sesoko Station in Sesoko Island, which is a marine research station of the University of the
Ryukyus. Several researchers have observed living radiolarians in the station and discovered several new things about
radiolarian biology. The participants can experience sampling of plankton-bearing sea water from the research boatwith using of a plankton net and observing living radiolarians at the Sesoko Station by several kinds of microscope. In
addition, we will visit Ie Island, which is located to the northwest of Sesoko Island. Permian–Cretaceous radiolarian
bearing sequences will be observed in this island.
