Jet propulsion at the smallest size scales: Kinematics and fluid dynamics of swimming Siphonophores

College of Natural Resources & Sciences

Siphonophores (Cnidaria: Hydrozoa) inhabit pelagic waters where representative species occupy depths ranging from the surface to the abyss. Locomotion by siphonophores is achieved by nectophore muscular contractions, which generate vortex ring wakes similar to jet-propelled medusa and squid. Using high-speed video analysis, we compare the kinematics and characterize wake structures of two different species of siphonophores during straight and turning swimming. By extracting the kinematics of individual nectophores, we quantify the formation time (T*) to characterize the jet wake. We show the T* generated by swimming physonect siphonophores are larger than other jet-propelled swimmers.

Juvenile Coho Salmon Life History Variants in Humboldt Bay Tributaries

College of Natural Resources & Sciences

We are assessing movement of juvenile Coho and adult straying among Freshwater Creek and two other Humboldt Bay tributaries using PIT tags and mark-recapture multi-state modeling. As salmon habitat becomes more fragmented through human actions, the need to better understand interactions between connected salmonid populations only grows. This research will focus on quantifying the frequency of juvenile dispersal between nearby watersheds to evaluate the need for changes in both management and monitoring. If there is significant movement between these watersheds, effective management and monitoring strategies of Freshwater Creek may need to be expanded to include nearby streams.

Kaulana Na Wai Eha

College of Natural Resources & Sciences

In central Maui in the Wailuku district, a system of fresh water streams that sustained thriving Hawaiian communities since time immemorial is all dried up. Kaulana Na Wai Eha (the famous four great streams) is comprised of the Waihe’e river, Waiehu, Iao, and Waikapu streams. These waterways have been diverted since the beginning of the plantation era, to grow sugarcane. The sugarcane industry has now cease but the water is still being diverted and sold to private corporations, continuously draining the streams leaving no water for the surrounding community. I will be talking about the legal battle between the Hawaiian Commercial & Sugar Co. v. Native Hawaiian Legal Corporation.

KCACTF: Opportunity, Experience, Expression and Knowledge

Stephan Chittenden, Art + Film Undergraduate Student

College of Arts, Humanities & Social Sciences

I will be sharing my experiences at KCACTF with an emphasis on sharing the opportunities available, but also how to manage time and expectations. In terms of opportunities I will be covering workshops but also NEXSTEP and the callbacks for summer internships, schools or jobs that can result from this experience. Beyond this, I want to cover when to take opportunities , and knowing when you've taken on too much.

KCACTF:Community, Art, Activism

Filip Amborski, School of Engineering Graduate Student

College of Arts, Humanities & Social Sciences

A presentation of the benefits for students looking to expand their network and skills in terms of acting, singing, and technical production knowledge. The Kennedy Center American College Theatre Festival provides opportunities to connect with peers from other schools, instructors from across the region, and working industry professionals. Students build their capacity to work in teams, expand their understanding of performance arts, and engage with the most contemporary material that is currently being developed. This experience can provide key exposure to new methodologies, and also offer opportunities to pursue summer and graduate programs, with additional scholarship considerations.

Keep on Truckin': The Social Life of a Log Trailer in Eureka, CA between 1880-1940

College of Arts, Humanities & Social Sciences

Eureka Ironworks, located in Old Town Eureka, was an iron manufacturing and fabrication company that was in business from the late 1800's through the 1940's. This project investigates the local economy and manufacturing process in the late 1800's through early 1900's, by focusing on the fabrication of log trailers. Through archival research in the Eureka Ironworks Historical Collection and Humboldt Room, this project aims to examine the social life of a log trailer in order to understand how this product fit into the Humboldt County economy. This research traces the log trailer from schematic, through fabrication, to its use in the local lumber industry.

Keeping it Glassy: Skeletal Analysis of Ancient Mesoamerican Obsidian Weapons

College of Arts, Humanities & Social Sciences

The project examined the damage caused to skeletal remains by ancient Mesoamerican weapons, due to the lack of research into this topic. The project focused on macuahuitls, wooden clubs lined with obsidian blades, which were produced through a combination of ancient and modern techniques. These weapons were then tested on animal crania acquired from a local butcher. The preliminary results show that the weapons left similar patterns of damage to the skeletal remains while having unique characteristics reflective of the individual weapon. These results show potential for future research in the area that could be compiled into a database similar to those used today for modern forensic cases.

Kenosha Mural Project

College of Arts, Humanities & Social Sciences

Working with photographer Ron Larson from the Kenosha Creative Space, a nonprofit organization in Kenosha, Wisconsin. Following the BLM protests, artists took to the streets of Kenosha, Wisconsin to express their feelings and emotions. Ron Larson began photographing the art around the city. We are here to share an interactive story map created to showcase the art around the city.
