巴塔哥尼亚峡湾：冰川雕琢与海洋廊道

Deep fjords in southern Chile were carved by ancient glaciers sliding toward the Pacific Ocean.
These narrow, steep-walled inlets now connect inland icefields to open marine ecosystems.
Cold, nutrient-rich waters flow through the fjords, supporting dense kelp forests and marine mammals.
Tectonic uplift continues slowly, raising former sea floors into terraced coastal cliffs.
Glacial silt suspended in runoff creates turquoise plumes visible from space.
Local communities rely on fjord access for fishing, transport, and ecotourism infrastructure.
Unlike river deltas, these fjords lack sediment deposition zones due to deep, fast currents.
Climate warming accelerates glacier retreat, altering freshwater input and salinity gradients.
The fjord network forms a fragmented but ecologically coherent spatial unit across the Andean spine.
Marine biodiversity here reflects both isolation and strong oceanic connectivity.
