Separation of microplastics from deep-sea sediment using an affordable, simple to use, and easily accessible density separation device

August 14, 2024
Author(s)
Katherine Shaw, Rachel Sandquist, Cameron Fairclough, Jesse Black, Alex Fitzgerald, Scott Gallager, Jennifer Lynch
Microplastics accumulate in the environment but methods to extract particles from sediment for quantification and identification often lack accuracy and reproducibility. Existing methods vary greatly and many do not achieve adequate microplastic separation

Microplastics absent from reef fish in the Marshall Islands: Multistage screening methods reduced false positives

November 29, 2023
Author(s)
Katherine Shaw, Jonathan Whitney, Eileen Nalley, Madeline Schmidbauer, Megan Donahue, Jesse Black, Raquel Corniuk, Kellie Teague, Catherine Pirkle, Rachel Dacks, Max Sudnovsky, Jennifer Lynch
Island communities, like the Republic of the Marshall Islands (RMI), depend on marine resources for food and economics, so plastic ingestion by those resources is a concern. The gastrointestinal tracts of nine species of reef fish across five trophic

Polymer Identification of Floating Derelict Fishing Gear from O'ahu, Hawai`i

September 28, 2023
Author(s)
Raquel Corniuk, Katherine Shaw, Andrew McWhirter, Harry Lynch, Sarah-Jeanne Royer, Jennifer Lynch
Discarded fishing gear (DFG) comprises most of the plastic in the North Pacific Ocean and causes environmental and economic losses. Building evidence on the material construction of fishing gear types is critical to develop solutions to reduce DFG amounts

Green sea turtles (Chelonia mydas) accumulate heavy metals near a former skeet shooting range in Kailua, O'ahu, Hawai'i

March 3, 2023
Author(s)
Katherine Shaw, George Balazs, T. Todd Jones, Harry Lynch, Jing Liu, George Cobb, David Klein, Jennifer Lynch
This study determined if green sea turtles (Chelonia mydas) in Kailua Bay, Oahu, in the Hawaiian Islands have elevated blood and scute Pb, As, and Sb concentrations resulting from lead deposition at a historic skeet shooting range. Blood and scute samples

TRACE ELEMENT CONCENTRATIONS IN BLOOD AND SCUTE TISSUES FROM WILD AND CAPTIVE HAWAIIAN GREEN SEA TURTLES (CHELONIA MYDAS)

October 16, 2020
Author(s)
Katherine Shaw, Jennifer Lynch, George H. Balazs, T. T. Jones, Jeff Pawloski, Marc Rice, Amanda French, Jing Liu, David Klein
Hawaiian green sea turtles (Chelonia mydas) are exposed to trace elements through water, sediment, and food. High concentrations of elements have been shown to decrease immune function, impair growth, and decrease reproduction in wildlife. This study
