Antarctic icebergs -- Hotspots of ocean life

e sum of the parts, and to answer questions across the different areas from ecology to chemistry and climate, scientists need access to all the data,” explained researcher John Helly of the San Diego Supercomputer Center (SDSC) at UC San Diego who managed the data. “And we need to reliably harvest this information at sea, thousands of miles from our shore-based labs, and to preserve it as a unique snapshot of these iceberg ecosystems at this point in history.”

Using SDSC-developed technologies, Helly collected the data using the SIOExplorer-in-a-Box digital library system (http://SIOExplorer.ucsd.edu) and then stored the information in collections at SDSC for access and analysis by scientists now and in the future.

Just getting to the icebergs was a challenge. First the scientists used satellite images to select two icebergs to study in detail. Then they sailed aboard the Antarctic research vessel Laurence M. Gould to reach their targets in the remote Weddell Sea, an arm of the Southern Atlantic Ocean that cuts into the Antarctic continent southeast of Cape Horn. The icebergs in the study were up to a dozen miles long and more than 120 feet high, with one extending nearly 1,000 feet into the depths.

Despite the risks of getting close to these mountains of ice – which can shed huge pieces or overturn without warning – the scientists began their shipboard sampling mere hundreds of feet from the icebergs and continued out to a distance of some five miles, where the icebergs’ influence was no longer detectable.

“Phytoplankton around the icebergs was enriched with large diatom cells, known for their role in productive systems such as upwelling areas of the west coast of the U.S. or ice-edge communities in polar oceans. As diatoms are the preferred food for krill, we expect the changes in phytoplankton community composition to favor grazing as a key biological process involved in carbon
