This section includes several activities related directly to primary production in the ocean—both by photosyn-thesis and chemosynthesis. Additional exercises found on the OE web site or OE CD include: • Message in the Bottles from the 2002 Arctic Ocean ...
Factsheet: Hydrothermal Vents
oceanexplorer.noaa.govThis sighting was a phenomenon . that had been predicted but never before confirmed. To their amazement, the scientists also found that these vents were surrounded by large numbers of organisms that had never before been seen. A diverse ecosystem was thriving here—in the absence of the sunlight
