Observed Strong Subsurface Marine Heatwaves in the Tropical Western Pacific Ocean
Marine heatwaves (MHWs) are discrete short-term extreme warm water events, which widely occur in the global ocean and coastal waters. Given the strong destructive impacts of MHWs on marine environment and ecosystem, the research on MHWs has become an im...Marine heatwaves (MHWs) are discrete short-term extreme warm water events, which widely occur in the global ocean and coastal waters.

Serpentinite-derived slab fluids control the oxidation state of the subarc mantle
It has been proved that arc magmas are more oxidized than the magmas erupted from the mid-ocean ridges, which is probably attributed to the input of oxidizing subduction components into the sub-arc mantle. However, it remains unclear what subduction com...It has been proved that arc magmas are more oxidized than the magmas erupted from the mid-ocean ridges, which is probably attributed to the input of oxidizing subduction components into the sub-arc mantle.

Nonlocal Population Sources Triggered Dinoflagellate Blooms in the Changjiang Estuary and Adjacent Seas
The Changjiang Estuary and adjacent sea area suffer from frequent harmful algal blooms, exerting a great impact on the ecological environment and fishery resources. About 60% of harmful algal blooms are caused by dinoflagellates. However, the population...The Changjiang Estuary and adjacent sea area suffer from frequent harmful algal blooms, exerting a great impact on the ecological environment and fishery resources.
