海洋“脱氧”是什么,为什么让人担心?
What is ocean deoxygenation, and why is it worrying?
海洋脱氧指海水溶解氧浓度下降的现象,既因变暖降低海水携氧能力,也因富营养化导致藻类分解耗氧。低氧海域扩大威胁鱼类生存、改变物种分布,并可能释放更多温室气体。
Ocean deoxygenation is the drop in dissolved oxygen, driven both by warming (warmer water holds less O₂) and by eutrophication that consumes oxygen as algae decay. Expanding low-oxygen zones threaten fish, shift species and may release more greenhouse gases.

什么是海洋“上升流”(upwelling)?
What is ocean upwelling?
上升流是风把表层温水吹离海岸、深层冷水带着丰富营养盐涌上来的现象,造就秘鲁等沿岸的高产渔场。
Upwelling is wind pushing warm surface water offshore so cold, nutrient-rich deep water rises, creating highly productive fisheries like off Peru.

深海“热液喷口”生态系统靠什么生存?
What powers deep-sea hydrothermal vent ecosystems?
在不见阳光的深海,喷口细菌利用硫化氢等化学物质通过化能合成制造有机物,支撑管虫、盲虾等独特生物群落。
In sunless depths, vent bacteria use chemicals like hydrogen sulfide via chemosynthesis to make food, supporting unique communities of tubeworms and blind shrimp.

什么是“蓝碳”?
What is blue carbon?
蓝碳指沿海和海洋生态系统(红树林、海草床、盐沼)通过植物和沉积物长期固定的碳,单位面积固碳效率常高于陆地森林。
Blue carbon is carbon locked by coastal and marine ecosystems (mangroves, seagrass, salt marshes); per area they often sequester more than terrestrial forests.

洋流是怎样影响气候的?
How do ocean currents affect climate?
洋流像巨大的传送带把热量从赤道送往高纬,例如北大西洋暖流让欧洲比同纬度更温暖湿润。
Currents act like a conveyor moving heat from the equator toward high latitudes; the North Atlantic Current keeps Europe milder than its latitude would suggest.

全球渔业资源被“过度捕捞”的比例有多高?
What share of global fish stocks is overfished?
联合国粮农组织评估显示,全球约三分之一的海洋鱼类种群已被捕捞到生物量低于能持续高产的水平,即“过度捕捞”。过度捕捞会破坏食物链、减少渔获并危及沿海社区生计。
FAO assessments indicate roughly one third of global marine fish stocks are harvested beyond levels that sustain maximum yield—'overfished'. Overfishing breaks food chains, shrinks catches and threatens coastal livelihoods.

什么是“海洋热浪”?
What is a marine heatwave?
海洋热浪是某片海域温度异常偏高并持续数天到数周的现象,常由洋流和大气环流异常叠加造成。它会引发珊瑚白化、藻类大量死亡和渔场位移,对海洋生物冲击很大。
A marine heatwave is an anomalously warm sea-temperature spell lasting days to weeks, often from unusual ocean and atmospheric circulation. It triggers coral bleaching, mass die-offs of algae and fish-range shifts, hitting marine life hard.

“大太平洋垃圾带”是什么?
What is the Great Pacific Garbage Patch?
它是北太平洋环流中因洋流汇聚而堆积大量塑料垃圾的区域,主要由破碎的塑料碎片组成,而非可见的“岛屿”。它说明塑料污染会随洋流长距离迁移并在海洋中累积。
It is a zone in the North Pacific gyre where currents concentrate vast amounts of plastic debris, made mostly of broken fragments rather than a visible 'island'. It shows how plastic pollution travels far by currents and accumulates in the ocean.

什么是渔业的“副渔获物”?
What is bycatch in fisheries?
副渔获物指捕鱼时顺带捕获的非目标生物,包括其他鱼类、海龟、海鸟和海豚等,常被丢弃或死亡。减少副渔获物需要改进渔具(如海龟排除装置)和避开敏感海域。
Bycatch is the non-target life caught incidentally while fishing—other fish, turtles, seabirds, dolphins—often discarded or killed. Reducing it needs better gear like turtle excluder devices and avoiding sensitive areas.

海洋酸化的化学过程是怎样的?
What is the chemistry behind ocean acidification?
大气 CO₂ 溶入海水后与水反应生成碳酸,进而释放氢离子、降低 pH,同时减少构建贝壳和珊瑚所需的碳酸根离子。自工业革命以来表层海水 pH 已下降约 0.1,看似微小却意味着酸度显著增加。
Dissolved CO₂ reacts with seawater to form carbonic acid, releasing hydrogen ions that lower pH and reducing carbonate ions needed by shells and corals. Since the industrial era surface pH has fallen about 0.1—small in number but a large rise in acidity.

海洋保护区(MPA)有什么用?
What are marine protected areas (MPAs) for?
MPA 是在海域里划定、限制或禁止捕捞和开采的特殊区域,让海洋生态系统休养生息、鱼群恢复。全球正朝着 2030 年保护 30% 海洋的“30×30”目标推进。
An MPA is a sea area where fishing and extraction are limited or banned so ecosystems can recover and fish stocks rebound. The world is moving toward the '30×30' goal of protecting 30% of the ocean by 2030.
