#1. Foreword by Yukihiro Takahashi, President of JpGU

I attended the EGU general assembly (GA) held in Vienna from April
23rd to 28th. It was a full-fledged face-to-face after COVID, and
I felt that the venue was more lively and full of smiles than usual.
About 19,000 people attended, 16,000 in person, up from 15,000 in
2018 pre-COVID. JpGU has a booth every year, and we are trying to
introduce the JpGU meeting and related journals, but I felt that
the number of Japanese people who stopped by there was particularly
small compared to the previous years. Looking around, it seems that
not one in 100 people was wearing a mask at the venue, in the city,
or on the subway.

At this year’s JpGU meeting, thanks to the cooperation of JpGU
members, the number of presentations has reached over 4,300, which
is quite close to the pre-COVID level. On the other hand, the number
of registered participants was about 4,700 as of May 8, and
considering that the number of participants in the pre-COVID year
was 8,000, I think there is still room for growth. Not only presenters,
but also those who are not presenting themselves this time, who have
not registered yet, please join us.

During the EGU GA period, meetings and receptions where representatives
of each academic society gather are held. This year, in addition to
meetings and receptions with representatives of academic societies
from around the world, there were individual discussions between the
AGU or EGU delegations and JpGU. Also JpGU delegation attended the
EGU (Equality, Diversity, Inclusion) committee as observer. Similar
meetings have also become popular at the AGU Fall Meeting, and I feel
that the global earth and planetary science community is moving toward
establishing stronger ties.

Also, there will be several meetings with each union at the upcoming
JpGU meeting. One of the changes at the EGU this time is that, in
addition to the meeting with three or more unions/societies that
have been held so far, two-party meetings with EGU and AGU have
been clearly set up, and more concrete and substantive exchanges
of opinions have been made. I feel that Japan is also expected to
play a not insignificant role in the movement to build more mature
international relations while understanding the position of each
union and academic society. Topics discussed at these various
meetings include efforts to address global issues such as carbon
dioxide emissions, child care at venues, relationships between basic
and applied research, or those between academia and private companies
and governments, and the next generation, including high school or
younger students, researcher development, gender and inclusion are
all important and urgent issues.

It is my hope that JpGU can contribute to the creation of a larger
community on these issues by listening to the voices of developing
countries, in addition to cooperation within the large unions.

(7) Announcement from Union Session

[Request from JpGU2023 U-07 Conveners]

Union Session U-07 “What is the true value of knowledge creation? Our
perceptions of science and society” (Conveners: Michiyo Shimamura,
Yuko Onishi, Brooks Hanson and Raj Pandya), conducted a survey to the
JpGU community in 2022. Based on the results, now we have started
another questionnaire survey.

In our previous session at JpGU 2022, U-04, a questionnaire survey
was conducted after the session to find out what exactly the members
of the JpGU community consider to be “responding to society’s mandate”
and what kind of activities they are actually engaged in to “respond
to society’s mandate”.

As a result, the following responses were obtained:

(1) more than 90% of the survey respondents answered that “connecting
science and society” is necessary, (2) researchers are the main actors
connecting science and society, but (3) the lack of resources (time
and costs) to “connect science and society” and proper evaluation on
scientific achievements are the issues.

The purpose of this survey is to find out how JpGU community members,
together with their stakeholders, are aware of the need to build a more
effective framework for “connecting science and society” and how to
connect these activities to the evaluation of scientific performance.
We will consider sharing the results of this survey with those who
cooperated with us at a later date.

Please give us 10 minutes of your time! We would appreciate your
cooperation in filling out this questionnaire.

Closing date of this survey: Friday, June 2, 2023

Lecturers: Dr. Tetsuichi Fujiki(JAMSTEC), Dr. Makio Honda(JAMSTEC),
Dr. Kanako Sato (JAMSTEC)
Event outline:
Argo is one of major global ocean observing systems that is measured
and monitored by >3000 Argo floats in cooperation with lots of
countries around the world. In recent years, BGC Argo, which equipped
with various biological and chemical sensors on Argo floats, has
begun to be deployed in the global ocean. In particular, the six
variables of dissolved oxygen, chlorophyll, nitrate, backscatter,
pH and irradiance have been identified as basic parameters in the
BGC Argo mission, and the number of scientific results based on the
output data of these sensors are rapidly increased by many researchers
and technicians in many countries. The BGC Argo is strongly expected
to play an important role in research and monitoring of changes in
the ocean environments, e.g., ocean acidification, carbon dioxide
absorption and marine ecosystems. This lesson gives the basic
explanation of BGC Argo, as well as the basics of how to find, obtain,
read out and use its data, including actual research results.

Event outline: The Earth’s atmosphere consists of multiple layers from
lower atmosphere to space and they interact with each other. We also
need to consider the global atmospheric circulation, which includes
the equator to the south and north poles. Therefore, to understand

from various regions. In this lesson, demonstrations and exercises will
be conducted to visualize and analyze various upper atmospheric data
using a single analysis tool.

Trophic niche separation of two non-spinose planktonic foraminifers
Neogloboquadrina dutertrei and Pulleniatina obliquiloculata.
The planktonic foraminifera Neogloboquadrina dutertrei and Pulleniatina
obliquiloculata are widely distributed in the present ocean, and their
depths are similar. The nitrogen isotope composition of two amino
acids revealed that the former is omnivorous (a mixture of herbivorous
and carnivorous), and the latter is herbivorous. Thus, this niche
separation in diet may allow both species to inhabit similar depth

@Daisuke Ishimura, Takashi Ishizawa, Masaki Yamada, Kaori Aoki &
Kai Sato
Washover deposits related to tsunami and storm surge along the north
coast of the Shimokita Peninsula in northern Japan.
After the 2011 Tohoku-oki earthquake and tsunami, paleotsunami
researches have been conducted at many places but the geological
evidence at the junction of Japan and Kuril Trenches was scarce.
This paper reported paleotsunami deposit that was formed at the
15-17 Century. The result will be a useful constraint for future
numerical modeling of large earthquake and tsunami at the junctional
