Aaron R. Cupp, Christopher F. Hartleb, Kim T. Fredricks, Mark P. Gaikowski
2016, Aquaculture Research (47) 234-242
Effects of eugenol (AQUI-S®20E, 10% active eugenol) sedation on cool water, yellow perch Perca flavescens (Mitchill), and warm water, Nile tilapia Oreochromis niloticus L. fish metabolic rates were assessed. Both species were exposed to 0, 10, 20 and 30 mg L−1 eugenol using static respirometry. In 17°C water and loading...

Impact of carbon dioxide level, water velocity, and feeding regimen on growth and fillet attributes of cultured rainbow trout (Oncorhynchus mykiss)
Patricia M. Mazik, P. M. Mazik, P. B. Kenney, J.T Silverstein
2016, Book chapter, Aquaculture
Production and management variables such as carbon dioxide (CO2) level, water velocity, and feeding frequency influence the growth and fillet attributes of rainbow trout (Oncorhynchus mykiss), as well as cost of production. More information is needed to determine the contributions of these variables to growth...

Eve L. Kuniansky, Jason C. Bellino
2016, Data Series 669
A goal of the U.S. Geological Survey Groundwater Resources Program is to assess the availability of fresh water within each of the principal aquifers in the United States with the greatest groundwater withdrawals. The Floridan aquifer system (FAS), which covers an area of approximately 100,000 square miles in Florida and...
Integrated water flow model and modflow-farm process: A comparison of theory, approaches, and features of two integrated hydrologic models
Emin C. Dogrul, Wolfgang Schmid, Randall T. Hanson, Tariq Kadir, Francis Chung
2016, Report
Effective modeling of conjunctive use of surface and subsurface water resources requires simulation of land use-based root zone and surface flow processes as well as groundwater flows, streamflows, and their interactions. Recently, two computer models developed for this purpose, the Integrated Water Flow Model (IWFM) from the California Department of...
Determination of dilution factors for discharge of aluminum-containing wastes by public water-supply treatment facilities into lakes and reservoirs in Massachusetts
John A. Colman, Andrew J. Massey, Sara L. Brandt
2016, Scientific Investigations Report 2011-5136
Dilution of aluminum discharged to reservoirs in filter-backwash effluents at water-treatment facilities in Massachusetts was investigated by a field study and computer simulation. Determination of dilution is needed so that permits for discharge ensure compliance with water-quality standards for aquatic life. The U.S. Environmental Protection Agency chronic standard for aluminum,...

2015, Scientific Investigations Report 2015-5123
From the contributions collected in this publication have emerged two important observations that have significance locally, nationally, and internationally. First, the fringing coral reef along the south coast of Moloka'i is one of the most extensive and luxuriant reefs in the eight main Hawaiian Islands. It is longer and more...
Surface-water quality in agricultural watersheds of the North Carolina Coastal Plain associated with concentrated animal feeding operations
Stephen L. Harden
2015, Scientific Investigations Report 2015-5080
The effects of concentrated animal feeding operations (CAFOs) on water quality were investigated at 54 agricultural stream sites throughout the North Carolina Coastal Plain during 2012 and 2013.

2015, Report
In 2014, the U.S. Geological Survey Great Lake Science Center (USGS-GLSC) and the USGS-Michigan Water Science Center partnered with the Great Lakes Commission (GLC) to conduct a series of four workshops with coastal practitioners and managers across the Great Lakes basin to highlight the need for, and get input on,...
Seasonal foraging responses of beavers to sodium-enhanced foods: An experimental assessment with field feeding trials
Jennifer Strules, Stephen DeStefano
2015, Journal of Mammalogy (97) 89-101
Salt drive is a seasonal phenomenon common to several classes of wild herbivores. Coincident with shifts of nutrient quality when plants resume growth in the spring, sodium is secondarily lost as surplus potassium is excreted. The beaver (Castor canadensis) is an herbivore whose dietary niche closely follows that of other...
Building sandbars in Grand Canyon

2015, Newsletter
Now, by implementing a new strategy that calls for repeated releases of large volumes of water from the dam, the U.S. Department of the Interior seeks to increase the size and number of these sandbars. Three years into the “High Flow Experiment” protocol, the releases appear to be achieving the...
Sediment and discharge yields within a minimally disturbed, headwater watershed in North Central Pennsylvania, USA, with an emphasis on Superstorm Sandy
Kelly O. Maloney, Dustin R. Shull
2015, Water and Environment Journal (29) 402-411
We estimated discharge and suspended sediment (SS) yield in a minimally disturbed watershed in North Central Pennsylvania, USA, and compared a typical storm (September storm, 4.80 cm) to a large storm (Superstorm Sandy, 7.47 cm rainfall). Depending on branch, Sandy contributed 9.7–19.9 times more discharge and 11.5–37.4 times more SS...
Estimation of historic flows and sediment loads to San Francisco Bay,1849–2011

2015, Journal of Hydrology (529) 1247-1261
River flow and sediment transport in estuaries influence morphological development over decadal and century time scales, but hydrological and sedimentological records are typically too short to adequately characterize long-term trends. In this study, we recover archival records and apply a rating curve approach to develop the first instrumental estimates of...

Resolving bathymetry from airborne gravity along Greenland fjords
Alexandra Boghosian, Kirsty Tinto, James R. Cochran, David Porter, Stefan Elieff, Bethany L. Burton, Robin E. Bell
2015, Journal of Geophysical Research B: Solid Earth (120) 8516-8533
Recent glacier mass loss in Greenland has been attributed to encroaching warming waters, but knowledge of fjord bathymetry is required to investigate this mechanism. The bathymetry in many Greenland fjords is unmapped and difficult to measure. From 2010 to 2012, National Aeronautics and Space Administration's Operation IceBridge collected a unique...
A geochemical and geophysical assessment of coastal groundwater discharge at select sites in Maui and O’ahu, Hawai’i
Peter W. Swarzenski, H. Dulaiova, M.L. Dalier, C.R. Glenn, C.G. Smith, Curt D. Storlazzi
2015, Book chapter, Coastal research library: Groundwater in the coastal zones of Asia-Pacific
This chapter summarizes fieldwork conducted to derive new estimates of coastal groundwater discharge and associated nutrient loadings at select coastal sites in Hawai’i, USA. Locations for this work were typically identified based on pronounced, recent ecosystem degradation that may at least partially be attributable to sustained coastal groundwater discharge. Our...
