Creating a Reliable Surveying Network: Does Adding New Survey Control Points to Paul Smith’s College Campus Enhance its Current Network?
Tue, 12/05/2017 - 18:48
Abstract: The goal of the project was to improve the current geometry of the Paul Smith’s College surveying network. Four new survey control points were added to the current network allowing for new connectivity to old control points. Previously, there was a Westside network and an Eastside network that were not connected and by connecting these two networks, it has expanded the current network further into the campus. Two different methods were used to help identify the new network. A traditional survey method, a closed traverse, was used to connect the old control points to the new control points by utilizing a Nikon DTM-352 series total station. A X90 OPUS GPS unit was used to connect the new control points into a geodetic network. After the data was collected a least squares adjustment was done to the closed traverse to correct for error within the traverse. The GPS data was processed by Topcon Tools utilizing a Continuously Operating Reference System (CORS) to obtain a better level of accuracy for the network it produced. The two different techniques used produced different results in the overall survey networks and supplied different coordinates than what has been previously used by students at the college. These results gained from the project are not of a consistent level of precision and are not recommended for use without conducting more closed traverses to increase precision within the network.

Wildfire Probability of Paul Smith’s College Lands
Tue, 12/05/2017 - 13:07
Abstract: For centuries, wildfires have been seen as devastating natural disasters burning homes, property and forests. For many years, man has tried to fight these fires to mitigate the damage that they do. In recent years, climate change has increased both the number of fires and the intensity at which they burn. We have developed a GIS model that incorporates factors such as slope, aspect, and land cover to determine what areas of Paul Smith’s College lands are prone to wildfires. Our goal was to find areas within the Paul Smiths College land that have a high probability for an intense wildland fire. We gathered our GIS data from online resources such as Cugir, NYS Clearing House and Earth Explorer. We then reclassified each of the data layers based on criteria determined from other scholarly papers to then use that criteria to develop our model. After running the model, we found twenty-two areas of interest also known as hot spots. We then proceeded to check five of the twenty-two hot spot areas to double-check that the characteristics that our model depicted were true hazardous areas.

Changes in aquatic communities resulting from interactions between climate change and invasive aquatic plants in the Adirondacks.

Abstract: Global climate change can act synergistically with invasive species leading to shifts in ecosystem structure and function. We assessed how a rise in water temperature influenced the potential competitive advantage of an invasive aquatic plant, Eurasian watermilfoil, (Myriophyllum spicatum) over a co-occurring native species northern watermilfoil (M. sibiricum). We also examined the interrelationship between water temperature, watermilfoil, and the aquatic ecosystem including periphyton growth and zooplankton abundance. The study was conducted using replicated mesocosms (3785-liter), with water heaters used to provide a range of temperatures. We found that increasing water temperature promoted the likely competitive advantage of the invasive species, M. spicatum: Survival of M. sibiricum plants was lower than that of M. spicatum across all temperature treatments with a mean survival rate of 24% and 96% respectively. M. sibiricum also showed significantly slower rates of plant growth (mean growth of 3.3 cm compared to 7.6 cm for M. spicatum) and reduced vigor compared to M. spicatum, with an average of less than half the number of growing meristems. Zooplankton densities averaged over 20 times higher in mesocosms with M. sibiricum compared to those with the invasive M. spicatum. Periphyton biomass was best explained by water temperature with an increase in growth in warmer water. Our study confirms that in the face of global climate change, the invasive M. spicatum will continue to exert dominance over its native counterpart. Our results also provide compelling evidence that the combined effects of climate change and invasive aquatic plants can dramatically alter aquatic ecosystems.
