Kathy Burek-Huntington, Kim Shelden, Kim Goetz, Barbara Mahoney, Dan Vos, Jessica Reiner, Jennifer Hoguet, Greg O'Corry-Crowe
Throughout the State of Alaska, ranging from the eastern Beaufort Sea to Bristol Bay, and within the boundaries of Cook Inlet, belugas are an important subsistence resource for Native communities. Cook Inlet belugas (CIBs, Delphinapterus leucas) are

Circular Economy in a High-Tech World

October 18, 2022
Author(s)
Kelsea Schumacher, Martin L. Green
The proliferation of electronics, batteries, and solar panels in recent decades has resulted in a substantial generation of end-of-life (EoL) "high-tech" products. Currently, these products follow a largely linear – extract, make, use, dispose – model, but

Effect of network connectivity on behavior of synthetic Broborg Hillfort glasses

Jose Marcial, Maria Cicconi, Carolyn Pearce, Jaroslav Klouzek, James Neeway, Richard Pokorny, Miroslava Vernerova, John McCloy, Emily Nienhuis, Rolf Sjoblom, Jamie Weaver, Russell Hand, Pavel Hrma, Albert Kruger
There is wide industrial interest in developing robust models of long-term (>100years) glass durability. Archeological glass analogs, glasses of similar composition, and alteration conditions to those being tested for durability can be used to evaluate and

Report on the DHS/NIST Workshop on Standards for an Enduring Capability in Wastewater Surveillance for Public Health (SWWS Workshop)

August 16, 2022
Author(s)
Nancy Lin, Stephanie Servetas, Scott Jackson, Katrice Lippa, Kirsten Parratt, Philip Mattson, Clare Beahn, Mia Mattioli, Sally Gutierrez, Michael Focazio, Ted Smith, Paul Storella, Sarah Wright
Wastewater surveillance is a promising approach to monitor biological and chemical contaminants on a community level in support of public health and safety decisions. Wastewater surveillance has recently been shown highly effective for the early detection

Towards a North Pacific Ocean long-term monitoring program for plastic pollution: A review and recommendations for plastic ingestion bioindicators

August 6, 2022
Author(s)
Matthew Savoca, Susanne Kuhn, Chengjun Sun, Stephanie Avery-Gomm, Anela Choy, Sarah Dudas, Sanghee Hong, David Hyrenbach, Tsung-Hsien Li, Connie Ka-yan Ng, Jennifer Provencher, Jennifer Lynch
Marine debris is now a ubiquitous component of the Anthropocene global ocean. Plastic ingestion by marine wildlife was first reported in the 1960s and since that time, roughly one thousand marine species have been reported to consume this debris. This

IG3IS Urban Greenhouse Gas Emission Observation and Monitoring Best Research Practices

August 1, 2022
Author(s)
Jocelyn Turnbull, Philip DeCola, Kimberly Mueller, Felix Vogel, Anna Karion, Israel Lopez Coto, James Whetstone
The Integrated Global Greenhouse Gas Information System (IG3IS) aims to coordinate an integrated global greenhouse gas information system, linking inventory and process model-based information with atmospheric observations and atmospheric modelling, to

Fracture Toughness Tests at 77 K and 4 K on 316L Stainless Steel Welded Plates

July 29, 2022
Author(s)
Jake Benzing, Nicholas Derimow, Enrico Lucon, Dash Weeks
In the framework of a collaborative project between ASME, NASA, and NIST, quasi-static fracture toughness tests have been performed at liquid nitrogen temperature (77 K, or -196 °C) and liquid helium temperature (4 K, or -269 °C) on weld specimens

Technical Framework for High Quality New Approach Methodologies (NAMs)

July 15, 2022
Author(s)
Elijah Petersen, John T. Elliott, John Gordon, Nicole Kleinstreuer, Emily Reinke, Matthias Roesslein, Blaza Toman
New approach methodologies (NAMs) are in vitro, in chemico, and computational approaches that can potentially be used to reduce animal testing. For NAMs that require laboratory experiments, it is critical that they provide consistent and reliable results
