The accretion history of fringing salt marshes located on the south shore of Cape Cod is reconstructed from sediment cores collected in low and high marsh vegetation zones. These marshes are micro-tidal, with a mean tidal range of 0.442 m. Their location within protected embayments and the absence of large rivers results in minimal sediment supply and a dominance of organic matter contributions to sediment peat. Age models based on 210-lead and 137-cesium are constructed to evaluate how vertical accretion and carbon burial rates have changed over the past century. The continuous rate of supply age model was used to age date 11 cores (10 low marsh and 1 high marsh) across four salt marshes. Both vertical accretion...

This dataset contains images obtained from unmanned aerial systems (UAS) flown in the Cape Cod National Seashore. The objective of the field work was to evaluate the quality and cost of mapping from UAS images. Low-altitude (approximately 120 meters above ground level) digital images were obtained from cameras in a fixed-wing unmanned aerial vehicle (UAV) flown from the lawn adjacent to the Coast Guard Beach parking lot on 1 March, 2016. The UAV was a Skywalker X8 flying wing operated by Raptor Maps, Inc., contractors to the U.S. Geological Survey. U.S. Geological Survey technicians deployed and mapped 28 targets that appear in some of the images for use as ground control points. All activities were conducted according...

This dataset contains field measurements of lakebed groundwater temperatures collected during three surveys in July 2008, August 2014, and August 2015, by using a handheld thermocouple probe and GPS at a permeable reactive barrier at Ashumet Pond, Falmouth, MA. The comma-separated file includes unique site identifiers, locations of measurement points, temperatures, dates, and types of measurement (groundwater, surface water, or control). Also included are ESRI raster datasets for each measurement date for (1) interpolated lakebed groundwater temperatures, and (2) interpolated lakebed groundwater temperatures normalized to the surface water temperature at the time of measurement. This data release is provided...

Remote sensing based maps of tidal marshes, both of their extents and carbon stocks, have the potential to play a key role in conducting greenhouse gas inventories and implementing climate mitigation policies. Our objective was to generate a single remote sensing model of tidal marsh aboveground biomass and carbon that represents nationally diverse tidal marshes within the conterminous United States (CONUS). To meet this objective we developed the first national-scale dataset of aboveground tidal marsh biomass, species composition, and aboveground plant carbon content (%C) from six CONUS regions: Cape Cod, MA, Chesapeake Bay, MD, Everglades, FL, Mississippi Delta, LA, San Francisco Bay, CA, and Puget Sound, WA....

Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes. The area is divided into the following four geographical areas to reduce file size and facilitate publishing: Massachusetts Bay from the Massachusetts-New Hampshire border south to Provincetown and Scituate and east to Stellwagen Bank; Cape Cod Bay from Provincetown to Scituate and south to Hyannis; Buzzards Bay from the Cape Cod Canal southwest to the State border including the Elizabeth Islands and extending north to Fall River and Mount Hope Bay; and Nantucket and Vineyard Sounds, from Hyannis south...

Imagery acquired with unmanned aerial systems (UAS) and coupled with structure-from-motion (SfM) photogrammetry can produce high-resolution topographic and visual reflectance datasets that rival or exceed lidar and orthoimagery. These new techniques are particularly useful for data collection of coastal systems, which requires high temporal and spatial resolution datasets. The U.S. Geological Survey worked in collaboration with members of the Marine Biological Laboratory and Woods Hole Analytics at Black Beach, in Falmouth, Massachusetts to explore scientific research demands on UAS technology for topographic and habitat mapping applications. This project explored the application of consumer-grade UAS platforms...

This dataset contains field measurements of temperature in shallow vertical profiles beneath a lake-bottom in the vicinity of a permeable reactive barrier (PRB) at Ashumet Pond, Falmouth, MA. From August 21, 2015 – September 3, 2015 vertical temperature profilers designed to quantify groundwater upwelling dynamics were installed at seven locations. Hollow stainless steel pipes (2.5 cm OD) were slotted horizontally to allow installation of iButton thermal data loggers (Maxim Integrated DS1922L, 0.0625 oC precision) protected with waterproof silicone caulking. The temperature profilers were gently tapped into the cobbly bed by first driving guide-hole of slightly smaller diameter. After installation, the thermal loggers...

This dataset contains the locations of independent survey points acquired on the same day that images were obtained from unmanned aerial systems (UAS) flown in the Cape Cod National Seashore. The overall objective of the field work was to evaluate the quality and cost of mapping from UAS images.

This data release includes comma-delimited datafiles (.CSV files) and geospatial datasets (GIS shapefile and raster datasets) from a survey of lake-bottom temperatures using a Fiber-Optic Distributed Temperature Sensing (FO-DTS) system in May 2007. The distribution of lakebed temperatures was determined over an 18-hour period in May 2007 using a LIOS fiber-optic distributed temperature sensing (FO-DTS) system (LIOS Technology, Cologne, Germany) connected to a 1000-m-long fiber cable shielded with rubberized armoring. The FO-DTS system measures temperature by means of optical fibers that function as linear sensors of temperature dependent laser light backscatter, producing temperature values to an accuracy of 0.01oC...

This dataset contains field measurements of direct groundwater seepage by using half-barrel style seepage meters permanently installed in a lake-bottom permeable reactive barrier (PRB) at Ashumet Pond, Falmouth, MA. The meters are a modified version of a standard half-barrel seepage meter. Each meter consists of a 208-L polyethylene, corrosion-inhibiting drum cut to a length of 0.8 m and fitted with a removable 0.56-m-diameter lid. A 1.3-cm-diameter hole was drilled into each lid to allow outflow or inflow to be measured. During installation, the top rim of each barrel was positioned to be at the expected grade after backfilling. Between 2004 and 2015, seepage rates at each meter were measured annually, with the...

This tidal marsh biomass field plot dataset is a compilation of aboveground tidal marsh biomass and species composition field measurements from six CONUS regions: Cape Cod, MA, Chesapeake Bay, MD, Everglades, FL, Mississippi Delta, LA, San Francisco Bay, CA, and Puget Sound, WA.
Mineralogical studies of coatings on quartz grains and bulk sediments from an aquifer on Western Cape Cod, Massachusetts, USA were carried out using a variety of transmission electron microscopy (TEM) techniques. Previous studies demonstrated that coatings on quartz grains control the adsorption properties of these sediments. Samples for TEM characterization were made by a gentle mechanical grinding method and focused ion beam (FIB) milling. The former method can make abundant electron-transparent coating assemblages for comprehensive and quantitative X-ray analysis and the latter technique protects the coating texture from being destroyed. Characterization of the samples from both a pristine area and an area heavily...

The U.S. Geological Survey (USGS) assisted the Massachusetts Department of Environmental Protection (MassDEP) with the Massachusetts Estuary Project (MEP), by delineating groundwater-contributing areas to various hydrologic features including ponds, streams, and coastal water bodies, throughout southeastern Massachusetts. These contributing areas were delineated over a 6-year period from 2003 to 2008 using previously published USGS groundwater-flow models for the Plymouth-Carver region (Masterson and others, 2009), the Sagamore (western) and Monomoy (eastern) flow lenses of Cape Cod (Walter and Whealan, 2005), and lower Cape Cod (Masterson, 2004). The original USGS groundwater-contributing areas were subsequently...
