During a stretch of frigid weather in late January 2026, ice choked the Hudson River along Manhattan’s western shore. The OLI (Operational Land Imager) on Landsat 8 captured this image of the wintry landscape around midday on Jan. 28. This image uses representational color to distinguish ice (light blue) from open water and snow. Vegetation appears red.
Much of the ice in the image likely floated there from farther upriver, where tidal currents are weaker and salinity is lower. These conditions allow water to freeze sooner and at higher temperatures than the faster-flowing, brackish water near the river’s mouth, shown here.

2026年1月下旬，受持续严寒天气影响，曼哈顿西岸的哈德逊河被冰层堵塞。1月28日中午前后，陆地卫星8号（Landsat 8）上的陆地成像仪（OLI）拍摄到了这幅冬日景观。该图像采用伪彩色以区分冰（浅蓝色）与开阔水域及积雪。植被呈现红色。
图像中的大部分冰块很可能是从更上游区域漂流至此的，那里的潮汐流较弱且盐度较低。相较于此处展示的河口附近流速更快且为咸淡水的水域，上游的环境使得水体能够在较高的温度下更早结冰。
