水润万物

The ocean holds about 97 percent of Earth’s water and covers 70 percent of our planet’s surface. According to the United Nations, the ocean may be home to 50 to 80 percent of all life on Earth. Even if you live hundreds of miles from a coast, what happens in the ocean is fundamental to your life.

Real satellite imagery from NASA’s Terra, Aqua, and Landsat missions takes the shape of whales and swirling clouds in the agency’s Earth Day 2024 poster, “Water Touches Everything.”

The major ocean basins – Atlantic, Pacific, Arctic, Indian, and Southern – shape our planet’s climate and weather by absorbing, storing, and moving heat, water, and carbon dioxide. For nearly five decades, NASA missions have enabled researchers to observe from above and measure changes in the ocean across days, months, seasons, and years. Scientists use our satellite and sub-orbital data and climate models to study ocean dynamics, sea level rise, hydrological cycles, marine life, and the intersections of land and sea.

Hear NASA Science Mission Directorate Art Director, Jenny Mottar, explain her inspiration behind this year’s poster concept and design.

海洋拥有地球约97%的水，覆盖地球表面的70%。据联合国称，海洋可能是地球上50%到80%生命的家园。即使你住在离海岸数百英里的地方，海洋中发生的事情对你的生活也至关重要。

在NASA的2024年地球日海报“水润万物”中，来自NASA的Terra、Aqua和Landsat任务的真实卫星图像呈现出鲸鱼和漩涡云的形状。

主要的海洋盆地–大西洋、太平洋、北冰洋、印度洋和南大洋–通过吸收、储存和移动热量、水和二氧化碳，影响着地球的气候和天气。近五十年来，NASA的任务使研究人员能够从高空观察和测量海洋在在几天、几个月、几个季节和几年里的变化。科学家们利用我们的卫星和亚轨道数据以及气候模型来研究海洋动力学、海平面上升、水文循环、海洋生物以及陆地和海洋的交汇。

请听NASA科学任务局艺术总监珍妮·莫塔尔（Jenny Mottar）介绍今年海报概念和设计背后的灵感来源。
