I am a veteran of the United States Navy where I worked as an Avionics Technician specializing in maintenance and repair for airborne navigation and communications systems. For several years after my military service I worked with sub-sea robotics in the offshore oil industry. I am an Electronics Technician for the Sediment Transport Group where I repair, program, and deploy various instruments.

DUNEX Pea Island Experiment
The DUring Nearshore Event eXperiment (DUNEX) is an aggregation of multiple scientific organizations collaborating to increase understanding of nearshore processes. The U.S. Geological Survey (USGS) has chosen Pea Island National Wildlife Refuge as a study location to investigate and characterize the magnitude and timing of changes to coastal morphology (i.e., dunes, shorelines), bathymetry, and...
Coastal and Estuarine Dynamics Project
Coastal and Estuarine Dynamics Project exists to support ocean, coastal and estuarine research. The staff have a broad set of skills; from instrument design and development to all forms of work at sea to software development and data management. The team has successfully deployed and recovered more than 1000 data collection platforms for research in the last 30 years.
Coastal and Estuarine Dynamics - Engineering
The Coastal and Estuarine Dynamics Project primarily uses off-the-shelf instrumentation and sensors to collect observations. Coastal and Estuarine Dynamics team designs and implements novel configurations for logging of data from sensors, and for deployment of these instruments in a wide range of estuarine, coastal, and ocean environments. Project staff continually evaluates instrument and sensor...
Coastal and Estuarine Dynamics- Equipment
The Coastal and Estuarine Dynamics Project maintains an extensive and diverse inventory of instruments for measuring oceanographic parameters in-situ over long periods of time (a few days to as long as one year) and platforms on which to deploy the instruments in estuarine, coastal, and deep ocean environments. These instruments measure a wide variety of parameters relevant to studies of sediment...
Supplementary data in support of oceanographic and water quality times-series measurements made at Thompsons Beach and Stone Harbor, NJ from September 2018 to February 2023
In 2012, Hurricane Sandy struck the Northeastern US causing devastation among coastal ecosystems. Post-hurricane marsh restoration efforts have included sediment deposition, planting of vegetation, and restoring tidal hydrology. The work presented here is part of a larger project funded by the National Fish and Wildlife Foundation (NFWF) to monitor the post-restoration ecological resilience of coa
Time-series measurements of oceanographic and water quality data collected at Thompsons Beach and Stone Harbor, New Jersey, USA, September 2018 to September 2019 and March 2022 to May 2023
In October 2012, Hurricane Sandy made landfall in the Northeastern U.S., affecting ecosystems and communities of 12 states. In response, the National Fish and Wildlife Federation (NFWF) and the U.S. Department of Interior (DOI) implemented the Hurricane Sandy Coastal Resiliency Program, which funded various projects designed to reduce future impacts of coastal hazards. These projects included mars
Water quality data from a multiparameter sonde collected in the Herring River during November 2018 to November 2019 in Wellfleet, MA
Management efforts of the tidally-restricted Herring River in Wellfleet, MA include research to understand pre-restoration sediment conditions. Submerged multiparameter sondes that measure optical turbidity were deployed at four sites landward and seaward of the Herring River restriction. Periodically, the sites were visited and additional turbidity measurements were collected with a handheld mult
Time-series measurements of oceanographic and water quality data collected in the Herring River, Wellfleet, Massachusetts, USA, November 2018 to November 2019
Restoration in the tidally restricted Herring River Estuary in Wellfleet, MA benefits from understanding pre-restoration sediment transport conditions. Submerged sensors were deployed at four sites landward and seaward of the Herring River restriction to measure water velocity, water quality, water level, waves, and seabed elevation. These data will be used to evaluate sediment dynamics and geomor
Meteorological data from Pea Island National Wildlife Refuge, North Carolina, 9/13/2021 to 10/24/2021
Meteorological data were collected as part of the DUring Nearshore Event eXperiment (DUNEX) on Pea Island National Wildlife Refuge in North Carolina during 2021. The DUNEX project is a collaborative, multi-agency experiment designed to provide comprehensive measurements of storm-induced processes on coastal habitats. The overarching goals of this study are to understand oceanographic processes and
Suspended-sediment concentrations and loss-on-ignition from water samples collected in the Herring River during 2018-19 in Wellfleet, MA (ver 1.1, March 2023)
The Herring River in Wellfleet, MA is a tidally-restricted estuary system. Management options including potential restoration of unrestricted tidal flows require an understanding of pre-restoration sediment conditions. Altering future tidal flows may cause changes in net sediment flux and direction, which could affect marsh restoration and aquaculture in Wellfleet Harbor. This research aims to mea
Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA (ver. 2, December 2023)
The data in this publication map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide regional context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. These data were collected as part of field activity 2021-022-FA and a collaboration with the National Park Service at Cape Cod National Seashore to moni

Low-altitude (80-100 meters above ground level) digital images of Town Neck Beach in Sandwich, Massachusetts, were obtained from a camera mounted on a small unmanned aerial system (UAS; also known as a drone). Imagery was collected at close to low tide on seven days bracketing coastal ocean storms to observe changes in beach and dune morphology. The images were geolocated by using the single-frequ
Calculation of a suspended-sediment concentration-turbidity regression model and flood-ebb suspended-sediment concentration differentials from marshes near Stone Harbor and Thompsons Beach, New Jersey, 2018–19 and 2022–23
The U.S. Geological Survey collected water velocity and water quality data from salt marshes in Great Channel, southwest of Stone Harbor, New Jersey, and near Thompsons Beach, New Jersey, to evaluate restoration effectiveness after Hurricane Sandy and monitor postrestoration marsh health. Time series data of turbidity and water velocity were collected from 2018 to 2019 and 2022 to 2023 at both sit

Calibrating optical turbidity measurements with suspended-sediment concentrations from the Herring River in Wellfleet, Massachusetts, from November 2018 to November 2019
The sediment budget in the tidally restricted Herring River in Wellfleet, Massachusetts, must be quantified so restoration options for the river can be evaluated. Platforms equipped with optical turbidity sensors were deployed seaward and landward of the Herring River restriction to measure a time series of turbidity, from which a time series of suspended-sediment concentration (SSC) can be estima
