Supraglacial lakes are created when water forms in depressions on top of a glacier, remaining there until it dissipates by seeping through crevasses, or cracks in the ice sheet. Despite their sometimes impressive size, supraglacial lakes may drain in a matter of hours under the right conditions, when the pressure they exert on the ice causes it to crack creating a sometimes spectacular lake draini ...[Read More]

To that end, last month marked a century since the Titanic sank after colliding with an iceberg, killing over 1,500 passenger ...[Read More]
