Issue 38 | Blue Pulse: Marine Conservation Bulletin

日期:

The 26th Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change, which has been postponed for a year due to the pandemic, is taking place in Glasgow, Scotland. Although the ocean is not the main topic of the conference, the outcome of the conference will determine the future of the ocean. The polar oceans are the fastest warming region and are a consistent focus of the Blue Pulse. Most sections in this issue discuss changes and conservation of the polar oceans under climate change and can be used as a reference for understanding the links between oceans and climate.

1) 第40届南极海洋生物资源养护委员会年会在线上举行。会议决定延续原有的磷虾捕捞配额分布方案,但是未能通过海洋保护区提案,关于气候变化的决议也未能通过。

The 40th meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was held online. The meeting decided to continue the existing measure of krill fishing allowance distribution but failed to adopt any marine protected area proposal or agree to a resolution on climate change.

4)白宫宣布美国将大规模扩建海上风电发现项目,此举将有利于实现美国的气候目标。新建的海上风电装置可以为1000万户家庭提供电力。此外,美国将投入1350万美元,针对风电发展对野生动物的影响进行深入研究。

White House Announces Plans for Massive Expansion of Offshore Wind Farms, which can help President Joe Biden meet the U.S.'s climate targets which can provide electricity for 10 million families. Meanwhile, it would spend $13.5 million to study the risks of offshore wind development to wildlife.

1)Steve Blackledge和Dyani Chapman:应该允许石油和天然气公司在北极熊的自然栖息地去勘探和抽取石油吗?对任何关心北极熊命运的人来说,答案都是否定的。我们希望法庭可以去实地考察真相,并督促政府重新制定计划,从而颁布对北极熊威胁较小,且重视保护的法律法规。

Steve Blackledge and Dyani Chapman:“Should oil and gas companies be allowed to explore and extract oil in the polar bear’s natural habitat? For anyone who cares about the fate of polar bears, that answer is no. We hope the courts will examine the facts on the ground and force the government back to the drawing board, leading to a regulation that’s far less threatening and much more protective of the polar bear.”

2)Doreen Leggett: 海豹数量的上升会给渔民造成很大的经济损失。瑞典《海洋哺乳动物保护法》写明渔民可以合法阻止海豹捕食养殖鱼类,但为了避免处罚,他们应该遵守国家海洋渔业局提出的规范和建议。但这些细节条款目前还不存在,因此渔民们进退两难,他们并没有时间,人力资源,资金和渠道去为完善这些规范和建议开展调查。

Doreen Leggett: The increasing number of seals locally is causing significant financial losses for fishermen. There is a section of the Marine Mammal Protection Act of Sweden that provides fishermen with the opportunity to deter seals, but to avoid penalties they are supposed to abide by a list of recommendations produced by National Marine Fisheries Service. That list does not yet exist. So, fishermen are in sort of a quandary, fishermen don’t have the time, staff, or capital to make those kinds of investments.

3)RightShip:全球最大的第三方海事调查组织和安全评估机构RightShip表示,国际海事组织(IMO)为2023年减少温室气体排放推出的现有船舶能效指数 (EEXI) 和碳排放强度指数 (CII)可能过于保守。仅考虑运营方面的因素,可能无法强制实施减碳策略,同时错过船舶能效设计指数(EEDI)的关键减排能力。

RightShip: RightShip, the world's largest third-party maritime survey organization and safety assessor, said the existing Energy Efficiency Index for Ships (EEXI) and Carbon Intensity Index (CII) introduced by IMO to reduce greenhouse gas emissions by 2023 may be too slow to enforce changes by considering only operational aspects, while missing the key emission reductions of the Energy Efficiency Design Index for Ships (EEDI) capacity.

4)Ian Morse:科学家们认为海底采矿很可能会导致大范围海床损伤,但是这些环境损伤在法律上还尚未界定。太平洋目前是世界上海底采矿的实验室,可能因此承受一些无法预估的风险。

Ian Morse:Mining will likely cause widespread damage in seabed, scientists say, but the legal definition of environmental damage when it comes to deep-sea mining has yet to be determined. The Pacific is currently the world’s laboratory for the experiment of Deep Seabed Mining and may take some risks which cannot be predicted.

1)Woods Hole Oceanographic Institution:一片加州大小的有毒藻床正移向北极圈

Woods Hole Oceanographic Institution: There’s a Toxic, California-Sized Algae Bed Creeping Into the Arctic

科学家发现世界上规模最大的带有毒囊的藻床正在靠近阿拉斯加海岸。这片藻类有1000公里长,350公里宽。科学家担心这种亚历山大链藻毒囊产生毒素会导致海洋生物的大规模死亡,危急数十个北极社区的粮食供应,甚至导致当地居民的疾病与死亡。

Researchers find that the largest toxic algae cyst bed is creeping into the coast of Alaska. The massive bed is more than 1,000 kilometers long and 350 kilometers wide. Researchers worried that the toxic bloom, produced by the cysts of the algae species Alexandrium catenella, could lead to mass die-offs of marine species, and imperil the food supply of dozens of remote Arctic communities—or even cause sickness and death in humans.

Chinadialogue: The Huiwen wetlands: balancing conservation and aquaculture

位于海南东部沿海文昌市八门湾到冯家湾一带的滨海湿地,长度约15公里,宽约1-4公里,因落在会文镇境内,被当地称作会文湿地。“十四五”海洋生态环境保护规划的要求下,当地进行了多种改革,以求东风螺养殖和自然保护的平衡。

The coastal wetland located in the area from Bamenwan Bay to Fengjiawan Bay in Wenchang City, on the eastern coast of Hainan, is about 15 kilometers long and 1-4 kilometers wide, and is locally known as Huiven Wetland because it falls within Huiwen Town. Under the requirements of the "14th Five-Year Plan" for marine ecological and environmental protection, various reforms have been carried out in order to strike a balance between Babylonia areolata cultivation and nature conservation.

4)Mongabay: 科学的对立面:当深海调查遇上采矿利益

Mongabay: ‘Antithetical to science’: When deep-sea research meets mining interests

深海研究高额的成本使得许多科学家不得不依靠一些有意去开采海底资源的公司的资金。目前,一半以上的深海生物学课题组都与政府或者公司合作去做一些基础调查。但与利益相关方的合作总会造成一些道德上的危机,而目前研究调查的透明度也有待于提高。

The high cost of studying deep-sea ecosystems makes many researchers must depend on funding from some companies which want to exploit the sea floor resources. More than half of the scientists in the small, highly specialized deep-sea biology community have worked with governments and mining companies to do baseline research. However, cooperation with stakeholders always creates some ethical crisis, and the transparency of current research surveys needs to be improved.

北极与地球其他部分相比更快地变暖,这种现象被称为北极放大,这是气候变化最显着的特征之一,对整个北半球气候具有重要的影响。有几种机制被认为是导致北极放大的原因;然而,仍然缺乏对它们相对重要性的定量理解。本研究表明,热力学耦合是未来放大和海冰损失的原因,因为它克服了动态耦合的影响,将放大和海冰损失减少了约 35%。研究结果证明了有针对性的数值实验可以量化特定机制在北极放大中的作用,从而更好地限制气候预测。
