On behalf of the conference organising committee and sponsors it is our great pleasure to welcome you to Tokyo for IsoEcol 2016. We trust that you will find the 10th IsoEcol, and the first in Asia, as stimulating and inspiring as past IsoEcol. We have more than 150 delegates and over 130 oral and poster presentations spread across 5 sessions. The high quality of the submitted abstracts made it difficult to assign the limited oral slots, but we trust that delegates will benefit from the traditional concurrent oral presentation format, and take full advantage of the two poster sessions to interact with colleagues. We are looking forward to hearing about the application of isotope techniques to a wide array of ecological systems and study organisms throughout the week. Traditionally IsoEcol meetings include a mid-conference field trip day, and we know participants will enjoy their excursion to the natural areas surrounding the iconic Mount Fuji. We also hope that you can take time to enjoy the beauty of Tokyo during the spring, and perhaps experience a hanami party under the cherry blossoms. Thank you for your participation and helping to continue the great IsoEcol tradition. We trust that you will find the conference productive and stimulating, enjoy your time in Tokyo, and return home with renewed vigour for isotope ecology. v vi 1 Scientific Program 1.1 Venue The venue for the scientific program is Ito Hall on Hongo Campus of The University of Tokyo.

To access the most up-to-date Conservation Outlook Assessment for this site, please visit https://www.worldheritageoutlook.iucn.org. Shiretoko SITE INFORMATION Country: Japan Inscribed in: 2005 Criteria: (ix) (x) Site description: Shiretoko Peninsula is located in the north-east of Hokkaido, the northernmost island of Japan. The site includes the land from the central part of the peninsula to its tip (Shiretoko Cape) and the surrounding marine area. It provides an outstanding example of the interaction of marine and terrestrial ecosystems as well as extraordinary ecosystem productivity, largely influenced by the formation of seasonal sea ice at the lowest latitude in the northern hemisphere. It has particular importance for a number of marine and terrestrial species, some of them endangered and endemic, such as Blackiston’s fish owl and the Viola kitamiana plant. The site is globally important for threatened seabirds and migratory birds, a number of salmonid species, and for marine mammals including Steller’s sea lion and some cetacean species. © UNESCO IUCN World Heritage Outlook: https://worldheritageoutlook.iucn.org/ Shiretoko - 2014 Conservation Outlook Assessment (archived) SUMMARY 2014 Conservation Outlook Good with some concerns The values of the site are intact despite a number of external threats.

    DEPARTMENT OF EARTH & PLANETARY SCIENCE DEPARTMENT UPDATE 2017 -2018 FROM THE CHAIR WELCOME TO OUR ANNUAL UPDATE write this introduction after returning from our summer geology field camp. What a treat. I met many of the students when they took their first geoscience class, EPS 50. The capstone field course showed how much these new alumni Ihave grown during their time in EPS to develop into creative and talented geoscientists. On page 13 we hear from one of our 66 new graduates, Departmental Citation recipient Theresa Sawi, about her efforts to understand how earthquakes influence volcanic eruptions. Our faculty, students, staff and alumni continue to make our department one of the world’s best. Our newest faculty member, Bethanie Edwards (page 3), broadens the department’s expertise to include marine biogeochemistry. Along with the arrival of Bill Boos and Daniel Stolper two years ago, we continue to expand our efforts to understand all MARINE SCIENCE aspects of Earth’s changing climate. GET TO KNOW OUR FACULTY There have also been some losses. After 36 years, Tim Teague retired. He may be irreplaceable, but we will try. After three years of dedicated service, always with a smile, Richard Allen’s term as chair ended, and he will continue to direct the Seismological Laboratory. Mark Richards moved to Seattle where he is the University of Washington’s provost. Accolades continue to pour in, and I highlight a few. The American Geophysical Union recognized recent Alumnus Leif BETHANIE EDWARDS Karlstrom with the Kuno Award (page 16) and Professor David Romps with the Atmospheric Sciences Ascent award.

Received 9 March 2015, revised 14 June 2015, accepted 16 September 2015 ABSTRACT The isotopic composition of carbon dioxide in the atmosphere is a powerful tool for constraining its sources and sinks. In particular, the 17O oxygen anomaly [Δ17O = 1000 × ln(1 + δ17O/1000) - 0.516 × 1000 × ln(1 + δ18O/1000)], with a value > 0.5‰ produced in the middle atmosphere, provides an ideal tool for probing the exchange of carbon dioxide between the biosphere/hydrosphere and atmosphere. The biosphere/hydrosphere and anthropogenic emissions give values ≤ 0.3‰. There- fore, any anomaly in near surface CO2 would reflect the balance between stratospheric input and exchange with the aforemen- 17 tioned surface sources. We have analyzed Δ O values of CO2 separated from air samples collected in Taipei, Taiwan, located in the western Pacific region. The obtained mean anomaly is 0.42 ± 0.14‰ (1-σ standard deviation), in good agreement with model prediction and a published decadal record.

  • Summer 2010 in Japan
    Summer 2010 in Japan From Late June through early August I spent my time in Japan doing research in relation to my dissertation, as part of the EAPSI Fellowship I was awarded. This was my first time in East Asia (or really, Asia) so of course I tried to get as many lifers of birds, mammals, and herps as possible. However most of my trips were bird focused and of short duration, as I generally only had a weekend (or usually a single day) for birding and mammalwatching. Also July and August are rather horrible months to be in Japan, with high humidity and heat, and animal activity tended to be rather low. Probably the most rewarding (mammal wise) was a night drive with Neil Davidson, an expat birder, in Ashyu forest near Kyoto. I managed 4 lifer mammals on this trip. Major references I used were the excellent Wild Mammals of Japan, the old and increasingly out of date bird finding guide to Japan (which actually contains a lot of good mammalwatching info) and the Kantori birding list. Japanese Macaque: Iwatayama Monkey Park I made a special Saturday morning visit to Iwatayama Monkey park in June to see this species, which is basically guaranteed. The monkeys are fed here and so a large troop is resident at the top of the steep hill. For a couple of hundred yen tourists can buy food to feed monkeys through the chainlink feeding hut at the top. Overall good lucks, but expect a zoo like atmosphere. Convenient for visitors in Kyoto, and covered in the Lonely Planet Guide for Japan Eurasian Red Squirrel: Supposedly common, but like the Siberian Chipmunk only a last minute encounter, and only encountered at Obhiro Forest Park in Hokkaido, where they were fairly common Japanese Squirrel: One individual seen near bird feeders at the Mount Fuji Bird Sanctuary.

  • Experimental Investigations of Photochemically-Generated Organic Aerosols and Applications to Early Earth and Mars
    Experimental investigations of photochemically-generated organic aerosols and applications to early Earth and Mars By Emily Faye Chu A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Chemistry in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Kristie A. Boering, Chair Professor Stephen R. Leone Professor Imke de Pater Spring 2013 Abstract Experimental investigations of photochemically-generated organic aerosols and applications to early Earth and Mars By Emily Faye Chu Doctor of Philosophy in Chemistry University of California, Berkeley Professor Kristie A. Boering, Chair Aerosols in planetary atmospheres play a critical role in radiative transfer and thus also in determining the penetration depth of UV radiation and atmospheric temperatures. For early Mars and an anoxic early Earth, aerosols may have significantly influenced the stability of liquid water at the surface, as well as climate and habitability, yet the study of aerosol formation remains poorly constrained by models and experiments, making conclusions difficult. Significant progress can be made in reducing these uncertainties by providing additional laboratory constraints and tests for the photochemical and microphysical models used to generate the greatly varying predictions about aerosol formation in terrestrial-like atmospheres. Photochemistry experiments measuring gas- and condensed-phase species were conducted to determine (1) the extent to which a photochemical
