Study Reveals Genetic Diversity and Population Structure of Wild Crop Relatives
The research team from IOCAS along with collaborators from Japan and Russia, revealed the genetic background of the important wild crop relatives.The wild relatives of cultivated Saccharina japonica belong to the genus Saccharina, with S. cichorioides serving as a vital source of wild germplasm for kelp breeding due to its superior tolerance and higher polysaccharide content. However, limited und...

New AI Model Helps Predict Seasonal Arctic Sea Ice
The research team from IOCAS has developed a new AI model for predicting the Arctic on a seasonal scale.Predicting the extent of September Arctic sea ice carries significant implications for climate change and Arctic shipping. However, seasonal-scale forecasts of September Arctic sea ice extent exhibit a "spring predictability barrier".To tackle this issu...

New Evidence Uncovers Origin of "Ghost-arc Signatures" in Global Mid-ocean Ridge Basalts
Recently, researchers from IOCAS revealed that molybdenum (Mo) isotopes provide new insights into the origin of ghost-arc signatures in MORBs.Mid-ocean ridge basalts (MORBS), far from subduction zones, are generally thought to be unaffected by subduction processes. However, some MORBs exhibit arc-like geochemical signatures—such as negative Nb anomalies and elevated H₂O/Ce and Ba/Th ratios...

Ocean Mixing Intensifies Central Pacific ENSO via Diabatic Heating, Study Reveals
Researchers from IOCAS revealed the important effect of ocean subsurface mixing on the growth of both El Niño and La Niña of the central Pacific type.The El Niño and Southern Oscillation (ENSO) is one of the most significant interannual variations in the global ocean-atmospheric system, which can strongly influence the climate of the Asia-Pacific region. It is therefore crucial to predict the happen...

Researchers Create Global 3D Dataset of Seawater pH Using Stepwise FFNN Algorithm
Researchers from IOCAS employed a Stepwise Feed-Forward Neural Network (Stepwise FFNN) algorithm, integrating observational data from the Global Ocean Data Analysis Project (GLODAP) to construct a global monthly 3D gridded pH dataset over the past 30 ye...Ocean acidification, driven by the continuous absorption of atmospheric CO₂, poses severe threats to marine ecosystems and biodiversity. Accurate assessment of seawater pH variations is essential for evaluating biological responses to acidification and...
