Antarctic icebergs -- Hotspots of ocean life

... 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 i...

DOE JGI sets 'gold standard' for metagenomic data analysis

...ed. "It's like when you're in the market for a digital camera, you can go to web sites like CNET to see the reviews, make the comparisons, and get some guidance for choosing the right product for your particular needs." Another major problem with metagenomes is binning. Binning is the process of iden...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

...storical averages. Using underwater digital video cameras, van Woesik and his team examined the rate of coral recovery at 13 different sites, and found that recovery rates increased over time; notably, sheltered bay areas, which suffered less in 1998, appeared to support recovery of outer-reef...

"With automated classification your accuracy goes down," Riordan said. Cloud shadows can look like water and Alaska rarely experiences a cloudless day, said Verbyla...

Fish species plays surprise role in aiding coral reef recovery

... filmed the reef’s recovery with remote underwater digital videos cameras. Remarkably, only two of the 27 herbivorous fish species present on the reefs had any significant impact on its recovery from algal overgrowth. What was most surprising was that the dominant browser was a rare batfish, a species previo...
