A record-breaking #phytoplankton bloom formed an elliptical ring around Chatham Island in Jan 2026. Sentinel-3 captured the structure 90 minutes before the widely shared NASA/VIIRS image. The bloom reached its peak in at least a decade. Check out our new #BCEarthGallery blog post:

Volcanoes as cloud factories:
Morning heating, rising moist air, and volcanic slopes โ the perfect setup for small cumulus clouds. โ๏ธ
Sentinel-3 captured this orographic cloud formation over Java, Bali, Lombok & Sumbawa โ stretching nearly 1,200 km.

Two icebergs grounded near #Antarctica appeared to be racing eastward. But they weren't moving at all. Drift ice flowing west created the illusion. Sentinel-2 reveals what is really happening. We traced one of them back to Clarke Glacier. ๐ง Visit our new #BCEarthGallery article:

A vast cloud-free region over the Southern Ocean: ~1150 km wide, formed by a strong high-pressure system. Its area is so large that entire Hurricane Melissa and Super Typhoon Fungwong (2025) would have fitted inside it.

Seasonโs greetings from above the Arctic.
Fractured sea ice and snow-covered terrain in the Nares Strait between Greenland and Ellesmere Island.
Warm wishes to everyone in our community, and thanks for another year of collaboration, curiosity, and shared enthusiasm for Earth observation!
Windstreaks are common on Mars, but rare on Earth. Patagonia is one of those exceptions: dried-out volcanic maars in the Pali-Aike field act as sediment sources, forming long streaks shaped by persistent winds.
