Yong-Jin Huang, Chun-Wei Chang, and Chih-hao Hsieh A long-standing central challenge in natural science is to detect the change point (aka regime shift) in the dynamics of natural systems using historical data. To address this scientific problem,
Hsiao-Hang Tao and Chih-hao Hsieh The research team led by Dr Hsiao-Hang Tao and Professor Chih-hao Hsieh from the Institute of Oceanography, National Taiwan University developed a novel analytical framework to investigate within-population spatial dynamics, and applied this method to three ecologically and economically-important fish populations. The team analyzed how [...]
The surface of the Earth has been getting warmer over the last few decades due to the increasing atmospheric CO2 concentration as a result of human activities. This is accompanied by the loss of glaciers and ice sheets in polar regions, resulting in sea level rise. Just last month,
Jinny Yang & Chih-hao Hsieh Prof. Chih-hao Hsieh and former master student, Jinny Yang, from the Institute of Oceanography, NTU, using a novel experimental setting, for the first time, demonstrated the empirical evidence supporting the “kill-the-winner” hypothesis operating in marine microbes. This finding conducted using microbial communities from the [...]
Fen-Hsun Chang and Chih-hao Hsieh Postdoctoral researcher, Feng-Hsun Chang and Prof. Chih-hao Hsieh from the Institute of Oceanography, NTU, proposed a novel approach to examine b-diversity effects on ecosystem functioning of metacommunities. This approach, demonstrated using microbial communities collected from the East China Sea across years, is published in [...]
Waterfalls are commonly seen in the mountainous regions of Taiwan. They are often famous attractions that attract tourists to stop by. The formation of waterfall results from the river water flowing over the highly steep riverbed or the escarpment. Are there waterfalls in the ocean interior? To answer this, [...]
Chun-Mao Tseng* Understanding the accumulation and sources of methylmercury (MeHg) in tuna species for reducing the risk of human exposure through tuna consumption is so important to human well-being and ecosystem health. Professor Tseng’s lab thus collaborated with Professor Reinfelder (Rutgers University) in the US to explore the accumulation [...]
Shou-En Tsao, Chun-Mao Tseng* Since the industrial revolution, the level of atmospheric carbon dioxide (CO2) has increased by ~50% due to human activities in the past centuries which accelerated global change and a warming threat to the earth. Meanwhile, the ocean has absorbed around 30% of the emitted anthropogenic [...]
Phosphorus (P) is an essential and growth-limiting nutrient for all living organisms and controls primary producers in marine environments. Dissolved Inorganic Phosphorus (DIP) in the surface ocean is often depleted, resulting in fast turnover times and stress responses as in genome adaptation and changes in cellular compositions for the microbes.
Due to its unique location, Taiwan is prone to extreme events linked to climate (e.g., typhoons) and tectonics (e.g., earthquakes). These extreme events can trigger submarine landslides in the form of turbidity currents.
The participation of the Taiwan Multi-scale Community Ocean Model (TIMCOM) in the Ocean Model Intercomparison Project (OMIP) experiments is introduced here, as part of phase 6 of the Coupled Model Intercomparison Project (CMIP6). Two ocean–sea ice model experiments are compared: (a) OMIP1, forced by the Coordinated Ocean-Ice Reference Experiments Phase [...]
The calcite shells of planktonic foraminifera, a type of zooplankton, are widely used to reconstruct past changes in oceanography and climate. One of the key assumptions made in such reconstructions is that the organisms have a fixed depth habitat in the water column through time, regardless of hydrographic changes. To [...]
IONTU’s Ph.D. candidate, Yuting Vicky Lin, and her advisor, Prof. Vianney Denis, published a study in the Journal of Biogeography on 16 July 2022. This study aimed to disentangle the effect of benthic habitats from the sea surface temperature on the distributions of reef fishes in a biogeographic transition zone. [...]

A research team, led by Prof. Ho-Han Hsu from the Institute of Oceanography, using newly compiled bathymetry, sub-bottom profiling and seismic data to illustrate seafloor morphology, submarine canyon networks and stratigraphic framework in Huatung Basin (HB) and an adjacent sub-basin offshore east Taiwan (Fig. 1). This work is published in [...]
Feng-Hsun Chang and Chih-hao Hsieh Postdoctoral researcher, Feng-Hsun Chang and Prof. Chih-hao Hsieh from the Institute of Oceanography, NTU, proposed a novel approach to examine how the predator and prey communities are assembled in order to understand how predator and prey diversity are often positively associated. This approach, using [...]
The Humboldt Current System is the world’s most productive eastern boundary upwelling system. It stretches along the long coast off Chile. Thanks to the abundant nutrients here, this region is characterized by high marine productivity
The variation of Kuroshio loop in the Luzon Strait is important for the momentum, heat, and salt budgets of the SCS basin. Regarding the ENSO effects on the Kuroshio in the Luzon Strait, previous studies primarily focused on the effects of basin-scale wind anomalies and remote effects from the tropics. [...]
The atmosphere and oceans act as a coupled system. They interact in various ways, including via ocean-sur-face wind stresses, downward radiation fluxes, and exchanges of surface heat/energy. Professor Yu-heng Tseng and his collaborators investigate how the common Sahara dust can change the atmosphere and ocean dynamical processes using a high-resolution [...]

Although not as obvious as surface runoffs, groundwater flowing across the seabed into the ocean, so-called Submarine Groundwater Discharge (SGD), indeed occurs in many coastal areas. SGD, comprising of terrestrial fresh groundwater flowing from the aquifers and seawater infiltrating through the permeable sediments, is regarded as a significant process of [...]
The South China Sea (SCS) is the largest marginal sea in the western North Pacific. Its surface thermal conditions greatly affect the weather and climate conditions in the sea and its adjacent landmass. Previous studies have suggested that the ocean dynamics in the SCS play a crucial role in local [...]
Folds and thrust faults developed in accretionary wedge off southwestern Taiwan may provide conduits for fluid migration from deep strata to seafloor as there are many seafloor seepage features formed in this area. High-resolution bathymetric data and backscatter images collected using an autonomous underwater vehicle (AUV) over three accretionary ridges [...]
Gaoping Submarine Canyon (GPSC) off southwestern Taiwan connecting to the Gaoping River receives extremely high sediment load, heavy seasonal precipitation, and high tectonic activity in the region. Moreover, the internal tide within the GPSC induces strong bottom currents resulting in sediment erosion and resuspension. To understand the effects of extreme [...]
