#1. Foreword by Yukihiro Takahashi, President of JpGU

The Goto Islands have beaches with water and sand as clear as Okinawa’s,
but some of the beaches are littered with marine debris. The main
types of litter are fishing gear such as fishnets and buoys, plastic
bottles and driftwood, including a several-metre-long freezer that
appears to have been used on a fishing boat. Plastics that are less
than 5 mm in size are called microplastics and are increasingly
recognised worldwide as a social problem. Many of the plastics we see
on beaches are classified as macroplastics, which are larger than that,
but it is thought that these larger plastics are crushed more
efficiently in the surf than at sea, and transformed into micro
plastics. Not only in the Goto Islands, but also in other parts of
Japan, marine debris drifts ashore and is repeatedly kidnapped by
waves, creating microplastics in the process. If you pick up plastic
bottles and other items scattered on the beaches of the Goto Islands
and Amami-Oshima Islans, you will notice that they are labelled in
Chinese and Korean. However, it is premature to conclude directly
from this that there is little waste flow out of Japan. Japan has
been exporting large quantities of plastic to Southeast Asia under
the guise of a resource, and the debris that departs from Japanese
rivers can sink to the seabed or travel far out into the Pacific Ocean.
In the East Pacific Ocean, there is an area four times the size of
Japan, known as The Great Pacific Garbage Patch, where marine debris
floats in abundance. Its location is thought to be determined by ocean
currents and winds, but studies of its shape and size variations are
very limited. Perhaps because most of it is located in the high seas,
I get the impression that it is not well recognized, but it is a
phenomenon that humanity should not meditate on. Research into the
biological effects of microplastics is still in its infancy, but this
fearless landscape implies that they have a significant impact on the
ecosystem. Understanding and solving the problem of marine plastics
requires the cooperation of a wide range of experts, including not
only ocean physics, which calculates ocean currents, but also
meteorology, which deals with wind systems, biology, which examines
the effects on living organisms, engineering, which is responsible
for improving measurement methods, and sociology and international
relations if the problem is extended to waste disposal and export.
The Ministry of the Environment seems to be aiming for Japan to make
a major contribution in this field, and the earth and planetary
science community needs a framework to support this foundation.

[Request for Volunteer Judges]
Each year we have a high number of entries for Outstanding Student
Presentation Award (OSPA), therefore your cooperation as judges
is a very important part of it.

#6. From Committees

(1) Working Group for the Japanese Society for Artificial Intelligence
(JSAI) Competition

GeoSciAI2024 ~Challenge for deep learning model development in the
earth and planetary science~

The Japan Geoscience Union and the Japanese Society for Artificial
Intelligence will jointly host a model development competition in
Geoscience! In recent years, AI technology has developed remarkably,
which affects the vast research fields. Geoscience is a research
field where various physical, chemical, and biological phenomena
are intricately intertwined, and the information is vast and diverse
in terms of both quantity and quality. Therefore, the contribution of
AI technology is becoming extremely significant in recent geoscience.
This competition aims to promote the integration of the geoscience
and information science through a model competition event.

There will be one proposal each from the earthquake, the meteorology,
and the space weather field.
Participants are required to register through the web page and submit
a technical paper summarizing the model development and results.

Anyone can participate in the competition
#You do not need to be a member of JpGU or JSAI

February 2024: Open of web page and each task
April 2024: Release of evaluation data, Technical paper instruction
Early May 2024: Deadline for submission
Late May 2024: Notification of results, Award Ceremony @ JpGU 2024

#6. Information from PEPS

(1) About APC (Article Publication Charge) Payment
Thank you for your continued understanding and support of PEPS.
Due to the delay in the renewal of the publication agreement with
SpringerNature, it has taken some time to process the APC payment
for PEPS. We apologize for any inconvenience this may cause and
thank you for your continued support of PEPS.

(2) Featured Articles
We will introduce the featured articles selected by the editor-in-chief
from the papers published in the past.

@ Hong Che, Jing Zhang, Qian Liu, Huijun He & Zhi-Qi Zhao:
Refining the contribution of riverine particulate release to the global
marine Nd budget.
Releasing neodymium (Nd) from particles along continental margins
may contribute to losses in the global Nd budget. This study provides
direct evidence for exploring the Nd cycle process in the estuaries.
The result suggests that the release of dissolved Nd from riverine
particles should be considered a “missing source” constraint on the
Nd mass balance in ocean waters. Moreover, particulate–seawater
interactions appear to be a crucial geochemical control and should
thus be considered in coastal environments when assessing the cycle
of trace elements.

(3) Latest Articles
The following articles were published.

@ Jun Yoneda, Kiyofumi Suzuki, Motoi Oshima, Michihiro Muraoka,
Yusuke Jin:
Empirical evaluation of the strength and deformation characteristics
of natural and synthetic gas hydrate-bearing sediments with different
ranges of porosity, hydrate saturation, effective stress, and strain

@ Kiwamu Nishida, Ryota Takagi, Akiko Takeo:
