reproduction rate and heart rate – when the heart rate increased, the reproduc- tion rate lowered. Christina received a certificate and a check from AIPG California Section for $250.


Second Place was awarded to Ellery McQuilin, for her project entitled “A Tale of Two Slopes: Aspect Creates Microclimates”. She was curious to see if the different north and south facing aspects in Lundy Canyon create substan- tially different temperatures and snow depth due to varying amounts of sun exposure. Ellery placed temperature sensors on the north and south facing slopes at 100 foot increments ranging from 7,400 to 7,900 feet elevation. She collected the snow depth with the snow poles and time-lapse cameras on the two slopes, recording snow depth at 15-min- ute intervals between November 2017 and February 2018. A total of 27,000 photos were used to populate a spread- sheet to calculate daily slope sunlight and snow depth.


due to its low angle in the sky. This caused the north facing slope to have colder temperatures and a longer dura- tion of snow coverage. The south facing slope was up to 14°C warmer than the north facing slope during the day, but cooled down to similar temperatures at night. Ellery concluded that both slopes create microclimates, places where the topography affects the local climate. The large temperature range of the south fac- ing microclimate stresses rocks, which results in more rock falls. She further concluded that the north facing micro- climate can be, at least temporarily, a refuge from climate change for plant and animal species which require colder tem- peratures and snow coverage to survive. Ellery received a certificate and check for from AIPG California Section for $150.

Scott received a certificate and a check from AIPG California Section for $100.


As always, it was a pleasure seeing so many very bright young students, who are passionate about science in general, and geology in particular. These young adults represent a very promising future for humankind!

Dave Sadoff with third place winner, Scott Cao


The Third Place Award went to Scott Cao for his project “Volatile Climate of the Miocene: A Glimpse into Our Future?” Scott wanted to determine how CO2 levels (the greenhouse effect) and organic carbon burial (the Monterey Hypothesis) affected the climate of the Miocene. Sediments from the Miocene were studied from several Ocean Drilling Program (ODP) sites. Five samples of Trilobatus Trilobus, a foraminifera, were picked from the sediments cores, cleaned, and analyzed through a mass      signature related to the ratio of stable isotopes of carbon: 13C to 12C.

She found the north facing slope received 0.06% of the solar energy that the south facing slope received. There were 21 days with no sunlight in December, and when the sun rose high enough in the sky to finally shine on the north facing slope it had low solar energy

Scott concluded that global CO2 levels were highest during the Mid-Miocene climatic optimum, and then decreased when temperatures decreased dur- ing the late Miocene, supporting the greenhouse effect. However, CO2 lev- els decreased during the late Miocene, but temperatures remained relatively constant, showing a deviation from the greenhouse effect.
