Jellyfish stings threaten people’s health and even life in coastal areas worldwide. Nemopilema nomurai is one of the most dangerous jellyfish in the East Asian Marginal Seas, which not only stings hundreds of thousands of people every year but also is assumed to be responsible for most deaths by jellyfish stings in China. However, there is no effective first-aid drug, such as antivenoms, for the treatment of severe stings by N. nomurai to date. In this study, we prepared a N. nomurai antiserum from rabbits using inactivated N. nomurai toxins (NnTXs) and isolated the IgG type of antivenom (IgG-AntiNnTXs) from the antiserum. Subsequently, IgG-AntiNnTXs were refined with multiple optimizations to remove Fc fragments. Finally, the F(ab’)2 type of antivenom (F(ab’)2-AntiNnTXs) was purified using Superdex 200 and protein A columns. The neutralization efficacy of both types of antivenom was analyzed in vitro and in vivo, and the results showed that both IgG and F(ab’)2 types of antivenom have some neutralization effect on the metalloproteinase activity of NnTXs in vitro and could also decrease the mortality of mice in the first 4 h after injection. This study provides some useful information for the development of an effective antivenom for N. nomurai stings in the future.

Tidal Charts of eight major ocean tides (M2, S2, N2, K2, K1, O1, P1 and Q1) are presented for the global ocean, with special emphasis on the East Asian Marginal Seas. The tidal Charts are produced on a 5′ × 5′ grid from a conventional finite difference hydrodynamical model for the purpose of providing a more reliable set of predictive constants. Preliminary results have shown that the conventional approach can be used to reproduce the tidal distribution of the global ocean and marginal seas together reason-ably well. It is also believed that further improvement with data assimilation can pro-vide more accurate harmonic constants for detiding use, especially for correcting altimetric data for Asian marginal seas.

Abstract. Using satellite observations, reanalysis data, and model simulations, this study investigates the effect of sea surface temperatures (SST) on interannual variations of lower stratospheric ozone in the southern high latitude. It is found that the SST variations across the East Asian marginal seas (5 °S–35 °N, 100 °E–140 °E) rather than the tropical eastern Pacific Ocean, where ENSO occurs, have the most significant correlation with the southern high latitude lower stratospheric ozone changes. Further analysis reveals that planetary waves originating over the marginal seas can be propagated to southern middle to high latitudes via two teleconnection pathways in summer and one pathway in autumn. The anomalous propagation and dissipation of ultra-long Rossby waves in the stratosphere strengthen/cool (weaken/warm) the southern polar vortex which produces more (less) active chlorine and enhances (suppresses) ozone depletion in the southern high latitude stratosphere on one hand, and impedes (favors) the transport of ozone from the southern middle latitude stratosphere to high latitude on the other. The model simulations also reveal that approximately 17 % of the decreasing trend in the southern high latitude lower stratospheric ozone observed over the past five decades can be attributed to the increasing trend in SST over the East Asian marginal seas.
