The fourth China-Russia joint Arctic expedition was launched on Thursday in Russia’s Far Eastern city of Vladivostok. Scientists from both countries will conduct major frontier basic research on the rapid climate changes in the Arctic region, focusing on the area from the Northwest Pacific to the Arctic Ocean, Xinhua News Agency reported on Thursday. Nine people from China will participate in the voyage.
At the launch ceremony, Wei Zexun, director of the First Institute of Oceanography, Ministry of Natural Resources (MNR), said the joint expedition will focus on the waters of the Northwest Pacific and the Arctic Ocean, further deepening scientific understanding of ocean dynamic processes, climate change patterns, and marine ecosystems in the study areas. It is not only a concrete measure to implement the cooperation consensus between China and Russia in the marine field, but also a vivid example of the two countries’ comprehensive strategic partnership of coordination in marine science and technology in the new era.
According to Du Libin, executive dean of the College of Ocean Science and Engineering, Shandong University of Science and Technology, the Arctic is highly sensitive to global climate change, and a frontier for ocean science, playing a key role in the “Polar Silk Road” initiative and China-Russia polar marine cooperation.
The joint expedition will highlight deeper marine research cooperation and innovation, while advancing polar scientific exploration and practical collaboration between the two countries, Du said.
According to Zou Jianjun, chief Chinese scientist of the scientific expedition team and a researcher at the First Institute of Oceanography, MNR, the expedition will last about 62 days. The scientists will conduct multidisciplinary surveys in the Chukchi Sea, East Siberian Sea, Lomonosov Ridge, Makarov Basin, and Amundsen Basin to study changes in the marine environment of these regions amid rapid climate change and reveal their response processes and feedback mechanisms in relation to global climate change.
A representative from the Pacific Oceanological Institute (POI), Far Eastern Branch of the Russian Academy of Sciences, said during the ceremony that the joint expedition is expected to strengthen Russia-China ties and expand cooperation in the Arctic and Pacific regions.
As freight volumes along the Arctic shipping route are steadily increasing, and the role of Arctic shipping route in the global economy is becoming increasingly important, comprehensive scientific research of the region has become necessary.

C | 奇趣植物和阴生植物在清凉房中“三重避暑” 与多肉植物区的烈日当空形成鲜明对比，位于百花厅附近的奇趣植物区和阴生植物区，则是一片“清凉世界”，秋海棠、空气凤梨、蕨类植物等常年生长于此。在奇趣植物区的“冷室”中，数十种秋海棠科植物组成室内景观，叶片颜色丰富、造型舒展。工作人员介绍，秋海棠虽然多分布在热带和亚热带地区，但尤其喜欢阴凉湿润的环境，高温和烈日暴晒容易让它们的叶片灼伤或枯萎，生长速度也会变慢；鹿角蕨、鸟巢蕨等蕨类植物，也需要湿润阴凉的环境，因此，它们的家园同样打造得浓荫环抱。为了给这些怕热喜阴的植物营造适宜的生长环境，夏天，园区采取“三重避暑”措施：定时打开雨林喷雾，为植物降温增湿；在“冷室”的顶棚做特别的遮光处理，避免强光直射和室内升温；适时打开空调，将室温维持在25℃左右。揭秘多肉家族控水有招为应对高温和烈日，不少多肉植物自带隐藏的“特异功能”：正午时分，许多仙人掌科植物会闭合表面的孔隙，防止水分蒸发；如果枝叶缺水，部分叶片就会“退化”成尖刺，减少自身的需水量；白毛掌、鸾凤玉、猴尾柱、白星等多肉植物，表面被“白毛”覆盖，这些白色棉毛可以遮阴降温、减少水分蒸发，同时反射强光。
