Increasing deep-water overflow from the Pacific into the South China Sea revealed by mooring observations

Nature Communications, 2023
Cold and dense water from the North Pacific Ocean that spills through the Luzon Strait, the only deep conduit between the South China Sea (SCS) and the Pacific Ocean, renews deep-water mass, modulates hydrographic and biogeochemical cycles, and drives ...

In situ magnetometry study on the origin of anomalously capacity in transition metal sulfides

ChemPhysMater, 2023
Cobalt sulfides are considered as promising candidates for lithium-ion battery (LIB) anode materials with high energy densities. Their energy storage mechanism is widely understood to involve the traditional intercalation and conversion reaction. However,

Response of the ocean natural carbon storage to projected twenty-first-century climate change [PDF]

, 2013
The separate impacts of wind stress, buoyancy fluxes, and CO2 solubility on the oceanic storage of natural carbon are assessed in an ensemble of twentieth- to twenty-first-century simulations, using a coupled atmosphere–ocean–carbon cycle model.

Observations of Rogue Seas in the Southern Ocean [PDF]

Physical Review Letters
We report direct observations of surface waves from a stereo camera system along with concurrent measurements of wind speed during an expedition across the Southern Ocean in the austral winter aboard South African icebreaker S.A.~Agulhas~II. Records include water surface elevation across a range of wave conditions, spanning from early stages of wave ...

Joint Channel Estimation, Data Decoding, and Group-Sparse Impulsive Noise Estimation for Slowly Time-Varying Single Carrier Underwater Acoustic Communications

IEEE Access
The Gaussian noise assumption is usually made for slowly time-varying underwater acoustic communication (UWAC) systems, which is entirely adequate for most cases.

Collaborative communication-based ocean observation research with heterogeneous unmanned surface vessels

Frontiers in Marine Science
Unmanned surface vehicles (USVs) are crucial in ensuring maritime safety and observation, attracting widespread attention and research. However, a single USV exhibits limited performance and cannot effectively observe complex marine environments.
