Distribution and behavior of trace metals in the subterranean estuary of an Arctic coastal lagoon
… importance of submarine groundwater discharge (SGD) to ocean chemical budgets will grow. In this study, we examined the distribution of select trace metals (Fe, Mn, V, U, Mo and Ba) in the STE, lagoon surface waters, and coastal sediments of Simpson Lagoon along the Beaufort Shelf of Alaska. …

A radiocarbon method and multi-tracer approach to quantifying groundwater discharge to coastal waters
… ocean (submarine groundwater discharge, or SGD) can be difficult to quantify. Geochemical tracers of groundwater discharge can reflect the cumulative SGD flux from numerous small, widely dispersed, and perhaps ephemeral sources such as springs, seeps, and diffuse discharge. The natural …

Promoting generalization of communication training by use of the iPad™.
… an iPad™ used as a speech generating device (SGD) to promote generalization to community settings. The participants were taught to use the iPad™ with the TapToTalk™ application in the training setting to request preferred items that would be accessible in a community setting. Multiple baseline …

Submarine Groundwater Discharge in the Southern Chesapeake Bay: Constraints From Numerical Models
… zone to produce submarine groundwater discharge (SGD). Groundwater flowing from the seabed serves as a significant pathway for contaminants and nutrients, producing an active biogeochemical reaction zone. In order to quantify the importance of SGD in geochemical and hydrologic budgets for the …

Evaluating the Effectiveness of Motor Planning with Core Vocabulary: A Behavior Analytic Account
… One form of AAC is the speech-generating device (SGD). Over the last ten years, tablet-based technologies including iPad minisⓇ have been emphasized in the SGD research (Lorah, Parnell, Whitby, & Hantula, 2014b). One of the limitations in the tablet-based technology literature is that there are …

Revisiting Generalization for Deep Learning: PAC-Bayes, Flat Minima, and Generative Models
… with an analysis of stochastic gradient descent (SGD) in supervised learning. By formalizing the notion of flat minima using PAC-Bayes generalization bounds, we obtain nonvacuous generalization bounds for stochastic classifiers based on SGD solutions. Despite strong empirical performance in many …

Investigating groundwater derived nutrient fluxes within Tauranga harbour, New Zealand
Submarine groundwater discharge (SGD) is one of the key pathways that connects land and ocean, delivering freshwater, nutrients, carbon, metals, and other chemical constituents to coastal waters. In New Zealand, local Māori have had a strong cultural connection to this natural process for …
