Title

Antarctic Icebergs Play Role in Global Climate

Message

The Epoch Times -- In a finding that has global implications for climate research, scientists have discovered that when icebergs cool and dilute the seas through which they pass for days, they also raise chlorophyll levels in the water that may in turn increase carbon dioxide absorption in the Southern Ocean.

An interdisciplinary research team supported by the National Science Foundation (NSF) highlighted the research in the journal Nature Geosciences.

The latest findings document a persistent change in physical and biological characteristics of surface waters after the transit of an iceberg, which has important effects on phytoplankton populations, clearly demonstrating “that icebergs influence oceanic surface waters and mixing to greater extents than previously realized,” said Ronald S. Kaufmann, associate professor of marine science and environmental studies at the University of San Diego and one of the authors of the paper. (Full Story)
