Forest cover is predicted to decline in the western US in the next century, due in part to increased hydraulic stress associated with climate change. There has been a large body of work done on adult trees in natural settings, but a smaller amount has been done on more vulnerable seedlings outside of the greenhouse.
Assessment of Potential Effects of Water-Supply Withdrawals on Groundwater Levels near the Hyannis Ponds Complex, Barnstable, Massachusetts
The USGS, in cooperation with the Town of Barnstable and MassWildlife, is assessing the potential effects of new water-supply withdrawals on groundwater levels in the Hyannis Ponds Wildlife Management Area on Cape Cod. A groundwater-flow model is being used to simulate the effects of several possible withdrawal and wastewater-return flow scenarios developed by the Town of Barnstable and...
Hydrologic Site Assessment for Passive Treatment of Groundwater Nitrogen with Permeable Reactive Barriers, Cape Cod, Massachusetts
In 2019 USGS completed a study designed to develop and evaluate a phased site-assessment approach for determining the hydrologic suitability of sites being considered for permeable reactive barrier installation on Cape Cod. The approach provides a template for town officials and other stakeholders to follow when considering PRBs for passive treatment of nitrogen in groundwater on Cape Cod and...
The U.S. Geological Survey, in cooperation with the Massachusetts Office of Coastal Zone Management (CZM) is conducting geologic mapping of the sea floor to characterize the surface and shallow subsurface geologic framework within the Massachusetts coastal zone. The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) that...
Estimation of Daily Streamflow and Water Availability in the Massachusetts Sustainable-Yield Estimator, Version 2.0
The Massachusetts Sustainable-Yield Estimator is a decision-support tool that provides estimates of daily unaltered streamflow, water-use-adjusted streamflow, and water availability for ungaged, user-defined sites in Massachusetts. In this recently completed study, version 2.0 of the original Sustainable-Yield Estimator (Archfield and others, 2010) was developed with minor changes to the...
Demand for biomass bioenergy has been increasing due to consumer choices, and changes in public policy in response to global climate change. Currently, in the United States, unprocessed wood waste is the primary source of biomass for energy production.
USGS’s extensive stream gage network has greatly advanced our hydrologic understanding of watershed dynamics through the calculation of long-term streamflow measurements. Discharge, however, is not a direct measurement but rather derived from measurements of channel area, water height, and velocity.
Northern New England is a fascinating landscape of conifers, unique wildlife, mountainous landscapes, and warming climates. Help us better understand whether red squirrel populations are responding to climate change and predict how that will impact the vulnerable boreal birds that they prey upon.
Assessment of Hydrologic and Water-Quality Changes in Shallow Groundwater Beneath a Coastal Neighborhood Being Converted from Septic Systems to Municipal Sewers
The U.S. Geological Survey and the U.S. Environmental Protection Agency are collaborating on a study to better understand changes to groundwater quality beneath a densely developed coastal neighborhood as it undergoes conversion from onsite wastewater disposal to municipal sewering.
The topic of how climate change will exacerbate the impacts of invasive species is at the cutting edge of conservation biology and applied ecology. We are looking for someone to work with a group of researchers and natural resource managers under the paradigm of translational ecology, producing publications and designing research that will improve conservation outcomes on the ground
We are inviting you to participate in an exciting project that brings together citizen science data from iNaturalist and other online platforms to improve currently static biodiversity databases. This project will ultimately identify invasive species, taxonomy changes, and potential climate migrants that will aid conservation efforts on public lands.
The drought of 2016 affected hydrologic conditions throughout New England. Responses of USGS groundwater observation wells to this event, however, were not uniform and were sometimes markedly different from site to site. Although USGS scientists were able to provide explanations for most of these situations, staff who participated in drought advisory panels realized the need for a quantitative...
