Abstract On October 20, 1937 the Tank Barge ARGO sank during a fall storm on western Lake Erie. The barge was reported to be carrying 100,000 gallons of crude oil and 100,000 gallons of benzol and was thought to have sunk in Canadian waters. The ARGO was identified as a potential polluting wreck in NOAA’s Remediation of Underwater Legacy Environmental Threat (RULET) project and ranked as the greatest legacy underwater environmental threat on the Great Lakes. However, the exact location, condition, and disposition of the sunken barge and its cargo were a mystery for over 78 years. On August 28, 2015 the Tank Barge ARGO was discovered by the Cleveland Underwater Explorers in U.S. waters, beginning a three month response by the U.S. Coast Guard Federal On-Scene Coordinator to mitigate the substantial threat to the environment and public health posed by the ARGO’s cargo. Rife with challenges, the response included complex dive operations, hot tapping, chemical lightering and storage, environmental protection and monitoring and severe logistical constraints, all of which required an extensive incident management organization and utilized almost every “special team” under the National Contingency Plan. This case study summarizes the response to the Tank Barge ARGO and details how “special teams” were utilized by the Federal On-Scene Coordinator to safely and effectively respond to the environmental threat. Specifically, the capabilities of the National Strike Force, District Response Group and District Response Advisory Team, and Scientific Support Coordinator during this response are highlighted and offered as a best practice for other oil and hazardous substance responses.

AbstractThe healthcare system is undergoing a noticeable transformation from a reactive, post-disease treatment to a preventive, predictive continuous healthcare. The key enabler for such a system is a pervasive wearable platform. Several technologies have been suggested and implemented as a wearable platform, but these technologies either lack reliability, manufacturing practicability or pervasiveness. We propose a screen-printed circuit board on bio-degradable hydrocolloid dressings, which are medically used and approved, as a platform for wearable biomedical sensors to overcome the aforementioned problems. We experimentally characterize and prepare the surface of the hydrocolloid and demonstrate high-quality screen-printed passive elements and interconnects on its surface using conductive silver paste. We also propose appropriate models of the thick-film screen-printed passives, validated through measurements and FEM simulations. We further elucidate on the usage of the hydrocolloid dressing by prototyping a Wireless Power Transfer (WPT) sensor and a humidity sensor using printed spiral inductors and interdigital capacitors, respectively.
