Implementation Plan of the National Cooperative Geologic Mapping Program Strategy—Northeast Region of the United States: New York and New England
No full textComplexly deformed igneous, metamorphic, and sedimentary rocks form the bedrock of the Northeast region of the United States. Variably thick unconsolidated sediments deposited by glacial, fluvial, and eolian systems locally cover the bedrock. New geologic mapping focuses on areas lacking modern, detailed studies or syntheses, and contributes to existing framework research. This report addresses plans for the continued development of regionally and nationally consistent geologic maps and map databases, efforts to answer outstanding geologic questions, and societal concerns associated with related geologic topics, such as hazards, geologic and hydrologic resources, and environmental issues
Telling Stories About the Ocean
No full textAkeia de Barros Gomes received an M.A. and her Ph.D. in Anthropology with a focus in Archeology from the University of Connecticut in 2008. She worked as a college professor before moving shifting to museum work. Currently, she holds the role of Senior Curator of Maritime Social Histories at Mystic Seaport Museum. De Barros Gomes is responsible for working on curatorial projects of race, Indigenous histories, ethnicity, and diversity in New England’s maritime activities. A major exhibition will open this fall featuring de Barros Gomes’ work mapping a more complex historical framework of New England’s maritime history by creating a new narrative of visual and material culture, archeology, oral traditions, and songs and performances.
Jason Mancini is the Executive Director of CT Humanities where he focuses on strengthening organizational partnerships, engaging diverse audiences, and anchoring Connecticut’s placemaking, public history, and integrative digital initiatives. Mancini holds an M.A. and his Ph.D. in Anthropology with a focus on Archeology and Ethnohistory of New England from the University of Connecticut. He co-founded the Akomawt Educational Initiative and is the former Executive Director of the Mashantucket Pequot Museum and Research Center.
Mancini and de Barros Gomes discuss their experiences re-indigenizing public history and education, speak about their current research, and offer explanation as to how we can use maritime history as a basis for studying historical injustices and to generate new insights on the past and the present
Twenty-Year Record of Salt Marsh Elevation Dynamics in Response to Sea-Level Rise and Storm-Driven Barrier Island Geomorphic Processes: Fire Island, NY, USA
No full textTwenty years of surface elevation table and marker horizon monitoring at three sites along the Fire Island (New York, USA) barrier island indicates that rates of marsh surface elevation change (Watch Hill, 4.4 mm year−1; Hospital Point, 3.5 mm year−1; Great Gun, − 0.3 mm year−1) were lower than the rate of monthly mean sea-level rise during the 2002–2022 monitoring period (5.1 mm year−1, NOAA Sandy Hook, NJ, water level station). The Great Gun monitoring site, with an elevation deficit relative to sea-level rise, shallow subsidence (surface accretion \u3e marsh elevation rate), low elevation capital, prolonged marsh surface flooding, and declining vegetation cover, displays characteristics common to deteriorating marshes. The submergence trend was not as evident at the other monitoring sites, but with low tidal range (0.4 m) and projections of accelerated sea-level rise, sustainability is questioned if marsh elevation change continues to lag behind the local rate of relative sea-level rise. Hurricane Sandy occurred during the monitoring period (October 2012), creating a new inlet located about 300 m from one of the monitoring sites. Surprisingly, no immediate signals of deposition or erosion were noted from the marker horizon sampling. Overwash sand deposits on the marsh surface were extensive along Fire Island, although not reaching the monitoring sites, and will likely provide opportunities for future salt marsh growth, as will the flood-tide delta created by the inlet. Projecting the future of barrier island salt marshes under a regime of accelerated sea-level rise and episodic storms requires knowledge of marsh elevation and accretion processes and geomorphic dynamics
Framing the Bettelheims: Finding a new approach to an extremely colorful but fairly unknown family of the American 19th century
No full textIn September 2018, Elkus entered the University of Rhode Island hoping to determine what, if any, historical importance was held in a large cache of documents that she had recently inherited. Hoping to identify an archival home for the Bettelheim Family Papers, Elkus set out to investigate the 19th century family that had produced them. Rather than expand outward from the several available Bettelheim protagonists, Elkus’s research became focused on a singular event in which young Dr. Felix A. Bettelheim attempted to obtain 5,000 Chinese contract laborers for the construction of the Panama Canal. The work ended up as a case study in ethnic relations and identity formation which asked how Felix Bettelheim, as a Jewish migrant and a member of a persecuted minority himself, could attempt to control the movement and migration of Chinese laborers, oblivious to the parallels that existed between his own experiences and those of the people he sought to exploit — ultimately seeking to understand how his venture contributed to the construction of his own sense of identity and belonging as an American. Elkus was awarded her masters in December 2022, but her research has only opened new lines of inquiry, leaving Elkus not with answers about the Bettelheim family, but only with questions of “what next?

Get PDFBiopotential electrodes play an integral role within smart wearables and clothing in capturing vital signals like electrocardiogram (ECG), electromyogram (EMG), and electroencephalogram (EEG). This study focuses on dry e-textile electrodes (E1–E6) and a laser-cut knit electrode (E7), to assess their impedance characteristics under varying contact forces and moisture conditions. Synthetic perspiration was applied using a moisture management tester and impedance was measured before and after exposure, followed by a 24 h controlled drying period. Concurrently, the signal-to-noise ratio (SNR) of the dry electrode was evaluated during ECG data collection on a healthy participant. Our findings revealed that, prior to moisture exposure, the impedance of electrodes E7, E5, and E2 was below 200 ohm, dropping to below 120 ohm post-exposure. Embroidered electrodes E6 and E4 exhibited an over 25% decrease in mean impedance after moisture exposure, indicating the impact of stitch design and moisture on impedance. Following the controlled drying, certain electrodes (E1, E2, E3, and E4) experienced an over 30% increase in mean impedance. Overall, knit electrode E7, and embroidered electrodes E2 and E6, demonstrated superior performance in terms of impedance, moisture retention, and ECG signal quality, revealing promising avenues for future biopotential electrode designs
