National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @daisygilardini | Antarctica is definitely my favorite location for iceberg photography. The incredible life cycle of an iceberg starts thousands of years before it even reaches the sea. Snow and ice form glaciers on land. Over centuries of compression and slow movement, these glaciers expand toward the open sea. Once an iceberg calves from the mother glacier, it will float on ocean currents, at the mercy of some of the most inclement weather conditions on the planet. Snow, rain, wind, violent storms, and huge waves sculpt and carve its surface into amazing shapes. The iceberg will flip upside down numerous times before disappearing into the depths of the ocean, where it starts its cycle all over again through evaporation.
