Group 1: Ocean Color
organized by Siswanto (JAMSTEC) and Ishizaka (Nagoya Univ.)
Sunday AM1,2 Session 1 – Ocean color: Mission status, progress, and operational
Monday AM1,2 Session 3 – Exploring tropical oceans: New research and programs
PM2 Session 4 – Exploring polar regions: New research and programs
Tuesday AM1 Session 5 – Ocean primary production: in situ and satellite estimation
AM2 Session 6 – Red tides: Spatiotemporal changes, drivers, and detection
PM1.2 Session 7 – Coastal ocean processes, optical properties, and fisheries
Marine environments are changing due to complex interactions of ocean, atmosphere, and land driven by human activities and climate variations. This session explores the pivotal role of ocean color observations, including those from satellites and UAVs, in observing and monitoring the changes. By harnessing ocean color observation with finer spatial resolution, provided by sensors like GOCI-II, SGLI, and OLCI, researchers gain valuable insights into worldwide environmental issues such as red tide, eutrophication, along with their ecological impacts, thereby facilitating adaptation and mitigation strategies. Ocean color observations also aid in comprehending land-ocean-atmosphere interaction. The use of ocean color observations, alongside other research methods like Argo floats, ocean surface drifters, numerical modeling, and machine learning, underscores the pivotal role of ocean color observations in our efforts to understand and address the evolving challenges our marine environments face, ultimately advancing our pursuit of marine environmental sustainability.
This group constitutes the 20th Korea-Japan/11th Asia Ocean Color Workshop.
Group 2: Indo-Pacific
organized by Ogata (JAMSTEC), Horii (JAMSTEC), Masumoto (Univ. of Tokyo), and Aiki (Nagoya Univ.)
Sunday AM1,2 Session N1 – Indo-Pacific dynamics: Part I
PM1 Session N2 – Indo-Pacific invited presentations
PM2 Session N3 – Indo-Pacific dynamics: Part II
Monday AM2 Session N4 – Indo-Pacific dynamics: Part III
Japan has a warm and humid climate due to the influence of the Kuroshio Current and the Asian monsoon. Additionally, phenomena like El Niño and the Indian Ocean Dipole Mode impact the climate in Japan and the wider Asian region through atmospheric Rossby waves. Japan has taken leadership in developing computer environments like Earth simulators and establishing observation networks such as TAO/TRITON and Argo buoy systems. Satellite observations are crucial for disaster prevention and fisheries management, with Japan at the forefront. These advancements also hold promise for Southeast Asia's environmental and disaster prevention efforts. We will organize research conferences on ocean circulation in the Indian Ocean/Pacific region for advancing climate and atmospheric-hydrosphere research.
This group represents a continuation of an annual ISEE workshop held in previous years titled "Approaches for Hydrospheric-Atmospheric Environmental Studies in Asia-Oceania".
Group 3: Small Satellite
organized by Ichikawa (Kyushu Univ.) and Ishizaka (Nagoya Univ.)
Sunday PM1,2 Session 2 – Observations with airborne, UAVs, and micro-satellites
Ocean observations based on ships and drifters are comprehensive, but limited in both time and space. Meanwhile, satellite observations can provide wide and frequent views, but they are surface-limited and weather-dependent. Recently, new observations using small aerial vehicles, such as drones, become practically available. They could provide not only cloud-free high-resolution views but also the capability of pin-point sampling of sea surface targets, such as tidal fronts and red tide patches, detected from higher altitudes. Therefore, we will organize an international research conference on observations using small aerial vehicles, in order to exchange our recent knowledge and ambitions.
This group represents a continuation of an annual ISEE meeting held in previous years associated with orbital and suborbital observations for the ocean.
Group 4: Air-sea Interaction
organized by Tomita (Hokkaido Univ.) and Aiki (Nagoya Univ.)
(all in Japanese)
Monday PM2 Session N5: Air-sea interaction: Part I
Tuesday AM1,2 Session N6: Air-sea interaction Part II
PM1,2 Session N7: Air-sea interaction: Part III
The ocean and atmosphere interact with each other on various spatio-temporal scales, exchanging energy and materials. The "air-sea interaction" mechanism is complex, and our understanding is not enough. For a better understanding of the ocean, atmosphere, and climate system, this session will focus on research on air-sea interaction conducted using various methods such as in-situ observations, satellite observations, and numerical models. Furthermore, we welcome the presentation of research on technology development, including data development, satellite retrieval, new observational instruments, etc. The language used for this session is “Japanese”, and oral or poster presentations will be accepted.
