A Method for Reducing Ocean Wave-Induced Magnetic Noises in Shallow-Water MT Data Using a Complex Adaptive Filter
Journal of Ocean University of Qingdao - Tập 22 - Trang 99-106 - 2023
In shallow-water areas, the marine magnetotelluric (MT) method faces a challenge in the investigation of seabed conductivity structures due to electrical and magnetic noises induced by ocean waves, which seriously contaminate MT data. Ocean waves can affect electric and magnetic fields to different extents. In general, their influence on magnetic fields is considerably greater than that on electri...... hiện toàn bộ
On the Study of Wave Propagation and Distribution in the Global Ocean
Journal of Ocean University of Qingdao - Tập 18 - Trang 803-811 - 2019
Based on the simulation with SWAN wave model and data of ERA-Interim from 1979 to 2016, how the waves propagate globally and why swell pools distribute in the eastern ocean were investigated in this study. The simulation results show that waves from North Pacific and North Atlantic mainly propagate southeastward or southward and swells generated in Southern Ocean spread northeastward. The waves fr...... hiện toàn bộ
Density Functional Theory Study of Marine Polybrominated Diphenyl Ethers in Anaerobic Degradation
Journal of Ocean University of Qingdao - Tập 22 - Trang 1353-1360 - 2023
Polybrominated diphenyl ethers (PBDEs) are a kind of serious pollutants in the ocean. Biodegradation is considered as an economical and safe way for PBDEs removal and reductive debromination dominates the initial pathway of anaerobic degradation. On the basis of experimental study, Octa-BDE 197, Hepta-BDE 183, Hexa-BDE 153, Penta-BDE 99 and Tetra-BDE 47 were selected as the initial degradation obj...... hiện toàn bộ
Development and potential of space-borne doppler wind lidar
Journal of Ocean University of Qingdao - Tập 2 - Trang 89-94 - 2003
The advantage of lidar over other wind sensors is presented in this paper. With more than 20 years research, the development of the space-borne wind lidar is reviewed. Longer-term investigation has made many technologies suitable for the wind lidar measurement from an orbital platform become mature. However, there are still some problems to be solved. In order to obtain the optimal performance in ...... hiện toàn bộ
Kelp Fucoidans Facilitate Vascular Recanalization via Inhibiting Excessive Activation of Platelet in Deep Venous Thrombosis Model of Mouse
Journal of Ocean University of Qingdao - - 2024
This study was carried out explore the mechanism underlying the inhibition of platelet activation by kelp fucoidans in deep venous thrombosis (DVT) mouse. In the control and sham mice, the walls of deep vein were regular and smooth with intact intima, myometrium and adventitia. The blood vessel was wrapped with the tissue and there was no thrombosis in the lumen. In the DVT model, the wall was une...... hiện toàn bộ
Salinity Acclimation Induces Reduced Energy Metabolism, Osmotic Pressure Regulation and Transcriptional Reprogramming in Hypotrichida Ciliate Gastrostyla setifera
Journal of Ocean University of Qingdao - - 2024
Coastal and estuarine protists are frequently exposed to salinity undulation. While the tolerance and stress responses of microalgae to salinity have been extensively studied, there have been scarce studies on the physiological response of heterotrophic protists to salinity stressing. In this study, we investigated the physiological response of the heterotrophic ciliate Gastrostyla setifera to a s...... hiện toàn bộ
A model study on dynamical processes of phytoplankton in Laizhou Bay
Journal of Ocean University of Qingdao - Tập 13 - Trang 23-31 - 2014
A three-dimensional ecosystem model, using a PIC (Particle-In-Cell) method, is developed to reproduce the annual cycle and seasonal variation of nutrients and phytoplankton biomass in Laizhou Bay. Eight state variables, i.e., DIN (dissolved inorganic nitrogen), phosphate, DON (dissolved organic nitrogen), DOP (dissolved organic phosphorus), COD (chemical oxygen demand), chlorophyll-a (Chl-a), detr...... hiện toàn bộ
DNA Methylation of pacap Gene Is Involved in Growth Superiority of Female Half Smooth Tongue Sole (Cynoglossus semilaevis) in Different Salinities
Journal of Ocean University of Qingdao - Tập 20 - Trang 169-180 - 2021
Pituitary adenylate cyclase activating polypeptide (PACAP) and growth hormone-releasing hormone (GHRH) play important roles in the GH/IGF growth axis in fishes. To determine whether epigenetic change is involved in the regulation of pacap and ghrh responses to low salinity stress in Cynoglossus semilaevis, the correlation between growth traits, DNA methylation status and gene expression level in l...... hiện toàn bộ
Geophysical Signature of the Shallow Water Flow in the Deepwater Basin of the Northern South China Sea
Journal of Ocean University of Qingdao - Tập 17 - Trang 791-798 - 2018
Shallow water flow (SWF), a disastrous geohazard in the continental margin, has threatened deepwater drilling operations. Under overpressure conditions, continual flow delivering unconsolidated sands upward in the shallow layer below the seafloor may cause large and long-lasting uncontrolled flows; these flows may lead to control problems and cause well damage and foundation failure. Eruptions fro...... hiện toàn bộ
Heat Insulation and Dissipation Processes in Nordic Seas in the Summer
Journal of Ocean University of Qingdao - Tập 20 - Trang 1297-1306 - 2021
The Nordic Seas have a significant impact on the climate system. Here 23-day air-sea heat fluxes were analyzed from an in situ air-sea coupled buoy deployed in the Lofoten Basin from 5 August 2012 to 27 August 2012. The buoy captured two stages of strong south and north winds. The observations indicate that warm and wet air transported by the south wind can lead to decreased sensible and latent he...... hiện toàn bộ
