I During ^th Chinese National Antarctic Expedition ( ( chianre), individual particle samples were collected from South-to-Antarctic during L 2013. A transmission electron microscopy with energy-dispersive X-ay spectrometry (tem-eds) is employed to analyze the Morpholo GY, mixing state, composition, and relative abundances of individual aerosol. Atmospheric particles were classified into four types:sea salt, mineral, s ' ich and C-ich. Sea salt Aerosols (SSA) were dominant in marine particles from South to Antarctic, and they were further into three Sub-types:fresh SSA, partially aged SSA, and fully SSA. Partially and fully aged SSA accounted for 86% The total SSA number. Interestingly, surface of partially aged SSA and fully aged SSAcontained abundant rod-iike Na2</b20 >S 0 4. Mineral dust particles increased in the coastal areas, which were by influenced air. In addition, we found this s-ich particles were abundant at two sampling sites (the Middle Eastern of Indian Ocean and Ant Arctic inland). The back trajectories of air masses indicated that this s-ich particles were mainly formed via the oxidation of dimethyl Sulfide (DMS) emitted from the marine phytoplanktons. Our study suggests this SSA aging process in the South hemisphere atmosphere was controlled by the DMS which is differ ENT from the SSA aging under the influence of anthropogenic pollutants in the North hemisphere.

The nutrients in atmospheric wet deposition to Zhanjiang Bay and their on the impacts marine E studied based on the rainwater investigation from May 2015 to April 2016. The results showed the rainfall during the year of investigation was significantly higher the than the average annual Rai Nfall due to the influence of El Nino. In rainwater, NOand SiO 3 ² concentrations were relatively high in summer and autumn, while NO B20>3 and PO4³ concentrations were Relatively high in spring and winter. The deposition fluxes of these nutrients were all highest in autumn, with a high average contribution (larger than 50%) to The wet deposition fluxes in a whole year. These seasonal variations were affected by rainfall, different sources to air masses, local human activities. A Super typhoon passing by in autumn, which brought heavy rains, contributed more to the highest deposition fluxes of Nutr Ients in autumn. The wet deposition could bring 2.04, 292.4, 8.13 and 45.8t/a of NO2^-<b113 >-N, NO3^-N, PO4^3- - p and SiO3^2--si into the Zhanjiang Bay. Their deposition in autumn might cause phytoplankton to increase in seawater in short period Phenomenon might be absent.

With many advantages of light weight, high specific st^rength ,corrosion resistance ,easyprocessing , recyc^^ing and so on, the aluminum alloy is widely applied in the field of ocean. Under the atmospheric environment of the South Sea

and affected by its climatic characteristics, the corrosion types of aluminum alloy is in accordance with the EV Olution of pitting corrosion intergranular corrosion and exfoliation corrosion. Based on the study of corrosion mechanic and phenomena of aluminum alloy,thecorrosion ty PES and protective measures of aluminum alloys applied in the marine atmospheric-environment of the South Sea are Ed in this paper.

objective Based on electrochemical noise technology, corrosion behavior Monitoring system of Q235 carbon steel is con Structed to monitor the corrosion process of Q235 carbon steel in the marine atmosphere. Methods the electrochemical noise data collected was analyzed by Time-domain spectrogram and frequency domain spectrogram. Results in the stage of 0.5 h-2.0 H (Sunny), the current noise amplitude was s Mall; The Time-domain spectra appeared a few transient peaks; White noise didn ' t appear on frequency spectra; The electrode was in passivation; From H to 47.5 h (rainy), the current fluctuated and the noise spectra appeared a large of transient; The slope of the PSD declined fast; The electrode surface was eroded; The electrode was in the steady pitting corrosion period. conclusion the monitoring system could continuously monitor corrosion Behaviors of Q235 carbon steel in the marine atmosphere.
