2023 January Seminar-The Measurement of Growth at the Base of the Food Chain

 Registration is closed for this event

CCA’s January meeting and seminar is guest speaker Benjamin Lowin, PhD student at Skidaway Institute of Oceanography and the University of Georgia on January 16th at 7:00 pm at at St. Peter’s Church.

Primary production is critical for understanding the carbon cycle and fisheries sustainability. He will be discussing a novel way to measure net community production -  the amount of growth after the metabolic costs of living are accounted for. He will discuss a Pressure of In-situ Gases Instrument (PIGI) system (which he built).  This instrument provides measurement of dissolved O2 and N2 in surface ocean waters to determine the amount of plant growth. He will present a brief background on his lab group, an overview of the PIGI system, and some initial data.

Benjamin was born in the Bay Area, California and moved to Switzerland when he was nine. A lifelong love of the oceans kept brining him back to it. He did his undergraduate at the University of British Columbia, a dual major in Biology, and Oceanography. He did his Master at the University of Southampton, UK, at the National Oceanography Center, on remote sensing of coccolithophore (phytoplankton that make chalk) blooms in the Southern Ocean. He spent a year and a half in Alaska, working on the Northern Gulf of Alaska Long Term Ecological Research Project, running an inline bio-optical (light measuring devices) system looking at primary production in the Gulf of Alaska. His current position at the Skidaway Institute of Oceanography, is with Sara Rivero-Calle studding optical oceanography.

The CCA’s January raffle prize is a a bait cast combo rod and reel and tackle box valued at $200.00.
