Radio spectrum analysis of Qiongzhou Strait-Beibu Gulf

Fifth Symposium on Novel Optoelectronic Detection Technology and Application, 2019
With the development of China's economy, the seaborne traffic volume along the Qiongzhou Strait-Beibu Gulf has been increasing. There is also a growing need to build ship networking to obtain data on ships, cargo, and navigational environments. However, China's unplanned spectrum resources are seriously insufficient. In this paper ,we set up a hardware

Comprehensive risk assessment of marine radioactivity in the Beibu Gulf of Guangxi

Marine Pollution Bulletin, 2021
In this paper, a marine environmental sensitivity index system was constructed based on three factors: the marine biological species sensitivity, the marine ecological value sensitivity and the social and economic sensitivity. Combined with numerical simulations of 137Cs in the Beibu Gulf under the condition of a level-7 nuclear accident, a ...

Two New Diterpenoids from the Beibu Gulf Gorgonian Anthogorgia caerulea

Zeitschrift für Naturforschung B, 2014
Two new diterpenoids, anthogonoid A and antsimplexin A (1-2), as well as a known diterpenoid, klysimplexin G (3), were isolated from a Beibu Gulf gorgonian coral, Anthogorgia caerulea. The structures of these compounds have been established by detailed spectroscopic analysis and by comparison with spectral data of related known compounds. Compounds 1-3

Composition and ecological distribution of ichthyoplankton in eastern Beibu Gulf

Acta Oceanologica Sinica, 2011
Surveys were conducted in four seasons in the eastern Beibu Gulf from July 2006 to November 2007, to determine the ichthyoplankton composition, abundance, as well as environmental factors impacted on their spatiotemporal distributions. The fish eggs and larvae were sorted from 303 zooplankton quantitative samples, in which at least 1 order, 60 families,

A meta-analysis of antibiotic residues in the Beibu Gulf

Marine Environmental Research
Antibiotic residue stands as a significant ongoing environmental issue, with aquaculture being a major source of annual antibiotic discharge into the ocean. Nevertheless, there is still an incomplete evaluation of antibiotic residues in the Beibu Gulf, an area encompassed by two prominent aquaculture nations, China and Vietnam.

Summer circulation structure and formation mechanism in the Beibu Gulf

Science China Earth Sciences, 2014
Due to limited in situ data and diagnostic numerical models, the summer circulation structure and formation mechanism in the Beibu Gulf have always been in controversy in the past 50 years. Therefore, a new three-dimensional hindcast model was built within the northwestern South China Sea (SCS), forced with the daily averaged wind, heat flux, lateral ...
