Gulper automous underwater vehicle

GulperAUV

Each gulper contains two liters of volume.  When ballasting operations are conducted, the gulpers are full of seawater.  Therefore, the AUV will not be able to dive if the gulpers are full of air.  They need to be in the “cocked” position before launch, so the upper chambers can fill with seawater when the AUV is launched.

After the mission, these water samples are analyzed either onboard the mother ship or back at the laboratory.  An ongoing software effort is developing the capability to trigger the gulpers based on the measurements of other on-board instruments.

Marine microbes

The Marine Microbe Group focuses on mechanisms and controls of microbial population dynamics. Our research has an emphasis on carbon cycling in marine ecosystems - processes which regulate carbon fixation and energy transfer to higher trophic levels. These processes are critical to sustainability of oceanic food webs, global climate and human health.

Biological Oceanography Group

One of the longest-standing projects of the Biological Oceanography Group is the Monterey Bay Time Series. Research ships and moorings have collected detailed datasets of temperature, salinity, oxygen, CO2, phytoplankton and other changing variables since 1989.
