Quantitative Depth Profile Of Prochlorococcus In The Pacific Ocean, Benjamin Carter Calfee
Quantitative Depth Profile Of Prochlorococcus In The Pacific Ocean, Benjamin Carter Calfee
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Prochlorococcus is a genus of extremely abundant marine cyanobacterium. This microbe is responsible for the majority of the primary production within marine environments and is thought to be the single most abundant photosynthetic organism. In addition to accounting for such a large portion of the world’s photosynthetic activity, Prochlorococcus functions with a genome much smaller than most other primary producers. Thus due to its general abundance and overall importance in oceanic ecosystems, an experiment was prompted to derive the spatial and numerical separation of the members of this genus across the Pacific Ocean through the use of quantitative polymerase chain …

Design Of An Underwater Video And Gps Mapping System For The Exploration Of Streambed Aquatic Populations, William Barbour
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
This design project was initiated due to the need for an underwater video mapping system optimized for exploration along the streambed or riverbed and under rocks. Such a system would be used for population mapping of fish and other aquatic species. The system also needed to incorporate global positioning system data with the visual data. The current prototype successfully fulfills the requirements for underwater practicality and visual and GPS data collection. It incorporates a compact waterproof camera with Sony lens, two Fenix high-intensity waterproof flashlights for illumination, a handheld DVR for recording video, and a Garmin 60CSx GPS unit. The …
