Surveillance for harmful algal bloom events and associated human and animal illnesses—One Health Harmful Algal Bloom System, United States, 2016—2018
(JOURNAL) [Published : Dec 18, 2020]
Harmful algal bloom (HAB) events can result from the rapid growth, or bloom, of photosynthesizing organisms in natural waterbodies. HAB events can be exacerbated by nutrient pollution and a warming climate (1) and can negatively impact the health of humans, animals, and the envir...
Reconstruction of Sea-Land Interactions between Terrestrial Vegetation Cover and Water Quality Constituents in the Mattapoisett Harbor Area During the 1991 Hurricane Bob Event
(JOURNAL) [Published : Nov 12, 2019]
Hurricane Bob passed over the New England region in August 1991, causing significant damage to life, property, and the environment, making it one of the costliest hurricanes in New England history. The environmental impact of a hurricane of this magnitude warrants careful assessm...
Factors influencing carbon stocks and accumulation rates in eelgrass meadows across New England, USA
(JOURNAL) [Published : Dec 01, 2020]
Increasing the protection of coastal vegetated ecosystems has been suggested as one strategy to compensate for increasing carbon dioxide (CO2) in the atmosphere as the capacity of these habitats to sequester and store carbon exceeds that of terrestrial habitats. Seagrasses are a ...
Managing climate refugia for freshwater fishes under an expanding human footprint
(JOURNAL) [Published : Jun 01, 2020]
Within the context of climate adaptation planning, the concept of climate refugia has emerged as a potential framework for addressing future threats to cold-water fish populations. Our aim is to evaluate recent cold-water refugia management efforts within the context of human wat...
Sediment retention by natural landscapes in the conterminous United States
(JOURNAL) [Published : Nov 01, 2020]
Soil functions provide vital ecosystem services, from sequestering carbon to providing food and moderating floods. Soil erosion threatens the provisioning of these services while deteriorating downstream water quality. Vegetation plays an important role in soil retention – by hol...
Submerged Vegetation Responses to Climate Variation and Altered Hydrology in a Subtropical Estuary: Interpreting 33 Years of Change
(JOURNAL) [Published : Mar 13, 2020]
Links between hydrologic modifications, flow and salinity regimes, and submerged aquatic vegetation (SAV) species composition and abundance were assessed with an empirical analysis of 33 years of monitoring data collected at nine sites in Florida’s Caloosahatchee River Estu...
Influence of infrastructure on water quality and greenhouse gasdynamics in urban streams
(JOURNAL) [Published : Jun 13, 2017]
Streams and rivers are significant sources of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4), and watershed management can alter greenhouse gas emissions from streams. GHG emissions from streams in agricultural watersheds have been investigated in numerous studies,...
A Review of Water Quality Responses to Air Temperature and Precipitation Changes 2: Nutrients, Algal Blooms, Sediment, Pathogens
(JOURNAL) [Published : Dec 20, 2018]
In this paper we review the published, scientific literature addressing the response of nutrients, sediment, pathogens, and cyanobacterial blooms to historical and potential future changes in air temperature and precipitation. The goal is to document how different attributes of w...
Realizing the Opportunities of Black carbon in Urban Soils: Implications for Water Quality Management with Green Infrastructure
(JOURNAL) [Published : Dec 10, 2018]
Soil ecosystem processes regulate the carbon cycle, and provide a sink for atmospheric black carbon (BC). Particularly in urban soil, BC may act as an effective sorbent of contaminants in green spaces. We determined soil hydrology, soil carbon pools (organic carbon, black carbon,...
Isolating Anthropogenic Wetland Loss by Concurrently Tracking Inundation and Land Cover Disturbance across the Mid-Atlantic Region, U.S.
(JOURNAL) [Published : May 05, 2020]
Global trends in wetland degradation and loss have created an urgency to monitor wetland extent, as well as track the distribution and causes of wetland loss. Satellite imagery can be used to monitor wetlands over time, but few efforts have attempted to distinguish anthropogenic ...
Seasonal disconnect between streamflow and retention shapes riverine nitrogen export in the Willamette River Basin, Oregon
(JOURNAL) [Published : Jan 01, 2020]
Watershed nutrient balance studies traditionally focus on annual fluxes. In areas with strongly seasonal, Mediterranean-type climate regimes, riverine nutrient export may be greater during wet seasons when hydrologic forcing overwhelms or bypasses retention mechanisms. By combini...
Unexpected Nitrogen Sources in a Tropical Urban Estuary
(JOURNAL) [Published : Mar 21, 2020]
Tropical urban estuaries are severely understudied. Little is known about the basic biogeochemical cycles and dominant ecosystem processes in these waterbodies, which are often low lying and heavily modified. The San Juan Bay Estuary (SJBE) in San Juan, Puerto Rico, is an example...
An Integrated Agriculture, Atmosphere, and Hydrology Modeling System for Ecosystem Assessments
(JOURNAL) [Published : Jan 24, 2020]
We present a regional‐scale integrated modeling system (IMS) that includes Environmental Policy Integrated Climate (EPIC), Weather Research and Forecast (WRF), Community Multiscale Air Quality (CMAQ), and Soil and Water Assessment Tool (SWAT) models. The centerpiece of the ...
Quantifying national and regional cyanobacterial occurrence in US lakes using satellite remote sensing
(JOURNAL) [Published : Apr 01, 2020]
Cyanobacterial harmful algal blooms are the most common form of harmful algal blooms in freshwater systems throughout the world. However, in situ sampling of cyanobacteria in inland lakes is limited both spatially and temporally. Satellite data has proven to be an effective tool ...
Projections of Atmospheric Nitrogen Deposition to the Chesapeake Bay Watershed
(JOURNAL) [Published : Dec 26, 2019]
Atmospheric deposition is among the largest pathways of nitrogen loading to the Chesapeake Bay Watershed (CBW). The interplay between future climate and emission changes in and around the CBW will shift the future nutrient deposition abundance and regime (e.g., oxidized vs. redu...
Watershed 'Chemical Cocktails': Forming Novel Elemental Combinations in Anthropocene Fresh Waters
(JOURNAL) [Published : Dec 01, 2018]
In the Anthropocene, watershed chemical transport is increasingly dominated by novel combinations of elements, which are hydrologically linked together as 'chemical cocktails.' Chemical cocktails are novel because human activities greatly enhance elemental concentrations and the...
Ecological differences influence the thermal sensitivity of swimming performance of two co-occurring mysid shrimp species with climate change implications
(JOURNAL) [Published : Feb 01, 2017]
Temperature strongly affects performance in ectotherms. As ocean warming continues, performance of marine species will be impacted. Many studies have focused on how warming will impact physiology, life history, and behavior, but few studies have investigated how ecological and be...
Statistical Models to Predict and Assess Spatial and Temporal Low-Flow Variability in New England Rivers and Streams
(JOURNAL) [Published : Oct 01, 2018]
In the northern hemisphere, summer low flows are a key attribute defining both quantity and quality of aquatic habitat. I developed one set of models for New England streams/rivers predicting July/August median flows averaged across 1985–2015 as a function of weather, slope...
