M1: Remote Sensing of Marine Hazards in the Coastal Environment

Convener:

Gade Martin (Germany)

Abstract:

Coastal marine environments, being invaluable ecosystems and host to many species, are under increasing pressure caused by anthropogenic impacts such as, among others, growing economic use, coastline changes and recreational activities. A continuous monitoring of those environments is of key importance for the identification of natural and manmade hazards, for an understanding of oceanic and atmospheric coastal processes, and eventually for a sustainable development and use of those vulnerable areas. Here, Synthetic Aperture Radar (SAR), because of its high spatial resolution, along with its independence of day- and nighttime and its all-weather capabilities, is one sensor of choice.

This Invited Session will focus on the way, in which SAR sensors can be used for the surveillance of changing marine coastal, environments, and how these sensors can detect and quantify processes and phenomena that are of high relevance for the local fauna and flora, for coastal residents and local authorities, and for a better quantification of hazards caused by global change.

O2: Monitoring and Forecasting Technologies for Marine Environments

Conveners:

Yu-Chun Lin (Taiwan), Chih-Chieh Young (Taiwan), Chung-Ru Ho (Taiwan)

Abstract:

The ocean covers 70% of the earth’s surface and more than 40% of the population lives within 100 km of the coast. As the climate continues to warm, it causes the rising of sea levels, increases ocean heat content, and grows events of marine hazards in the foreseeable future. These changes potentially affect biological fields, including human beings, more frequently, leading to less time for response. This changing marine environment is complex due to the interactions of different fields and different scales of temporal and spatial. Therefore, it is our primary interest to understand the past, present, and future changes in the ocean with newly developed theory, methods, and technology. In this session, we welcome all studies using the approaches of in-situ and remote observations, numerical models, and artificial intelligence to monitor and forecast the changes in the marine environment, including but not limited to the processes of coastal dynamics, ocean circulations, and interactions of marine biology and physics in different spatial and temporal scales. We aim to bring together experts to exchange recent research progress on these topics to provide important insights into the response of the marine environment to future climate change and the implications for global and regional climate.

T1: Tropical Cyclone-Marine Heatwave Interactions: From Coastal Ocean to Deep Ocean

Conveners:

Gad Levy (USA), Iam-Fei Pun (Taiwan), DanLing Tang (China)

Abstract:

Tropical cyclones (TCs) and marine heatwaves (MHWs) are among the most dangerous natural disasters on Earth. With gusty winds and heavy rainfall, TCs threaten inhabitants in coastal regions of the tropics and subtropics every year, causing significant damage and loss of life. MHWs, associated with prolonged periods of excessive heat, exert tremendous stress on ocean ecosystems, altering the habitats of marine life and fish species. Under the influence of climate change and global warming, these atmospheric and oceanic extremes are expected to become more frequent, and their compound effect poses an even greater threat, jeopardizing human communities. This session invites contributions on all aspects regarding TCs, MHWs, and their interactions, spanning from coastal waters to the deep ocean.
