Listening practice: The satellite that reads ocean colors

This morning, look at the ocean as if it were a living map. From a beach, seawater may look simply blue or green. From space, those colors can carry information about tiny organisms, dust in the air, clouds, and the health of a changing planet. According to NASA, its PACE mission, short for Plankton, Aerosol, Cloud, ocean Ecosystem, was launched in February twenty twenty-four to study the links between the ocean and the atmosphere.

节目导览

本期是一集面向高三学生的英语听力训练，主题是 NASA 的 PACE 卫星如何通过「海洋颜色」观察浮游植物、气溶胶、云与气候之间的联系。
音频按三段式安排：先完整听一遍英文科普叙述；中段用中文抓主线、拆关键词和长难句；最后把同一段英文原文完整重播，方便带着理解再听一次。

本期重点

  • PACE 的全称是 Plankton, Aerosol, Cloud, ocean Ecosystem，任务关注海洋与大气之间的联系。
  • Phytoplankton 是海洋食物网底层的微小植物和藻类，也和氧气、碳循环有关。
  • Ocean Color Instrument 能读取更细的光谱信息，帮助科学家区分不同浮游植物群落。
  • 这些数据可用于有害藻华预报、海洋管理、渔业和空气质量研究。
