Nearshore water quality and coral health indicators along the west coast of the Island of Hawaiʻi, 2010–2014
Coral reefs worldwide are experiencing rapid degradation in response to climate and land-use change, namely effects of warming sea-surface temperatures, contaminant runoff, and overfishing. Extensive coral bleaching caused by the steady rise of sea-surface temperatures is projected to increase, but our understanding and ability to predict where...

Development and application of surrogate models, calculated loads, and aquatic export of carbon based on specific conductance, Big Cypress National Preserve, south Florida, 2015–17
Understanding the carbon transport within aquatic environments is crucial to quantifying global and local carbon budgets, yet limited empirical data currently (2021) exist. This report documents methodology and provides data for quantifying the aquatic export of carbon from a cypress swamp within Big Cypress National Preserve and is part of a...

An assessment of the economic potential of lignite and leonardite resources in the Williston Basin, North Dakota
The Bureau of Land Management (BLM) requested assistance from the U.S. Geological Survey (USGS) to conduct an assessment study to identify areas that may have economic potential for the future extraction of lignite and leonardite resources in the Williston Basin in North Dakota. The study will be used by the BLM to assist with the preparation of a...

Coking coal of the United States—Modern and historical coking coal mining locations and chemical, rheological, petrographic, and other data from modern samples
Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas,...

Monitoring wetland water quality related to livestock grazing in amphibian habitats
Land use alteration such as livestock grazing can affect water quality in habitats of at-risk wildlife species. Data from managed wetlands are needed to understand levels of exposure for aquatic life stages and monitor grazing-related changes afield. We quantified spatial and temporal variation in water quality in wetlands occupied by threatened...
Smalling, Kelly; Rowe, Jennifer; Pearl, Christopher; Iwanowiczl, Luke R.; Givens, Carrie E.; Anderson, Chauncey W.; Mccreary, Brome; Adams, Michael J. Comparison of specimen and image-based morphometrics in Cisco
Morphometric data from fish are typically generated using one of two methods: from direct measurements made on a specimen, or by extracting distances from a digital picture. We compared data on twelve morphometrics collected with these two different methods on the same collection of Cisco Coregonus artedi to assess the degree of bias in...
O'Malley, Brian; Schmitt, Joseph; Holden, Jeremy P.; Weidel, Brian C. Historic population estimates for bottlenose dolphins (Tursiops truncatus) in Aragua, Venezuela indicate monitoring need
This study reports historic capture-mark-recapture survival and abundance estimates of common bottlenose dolphins (Tursiops truncatus) based on photo-identification surveys of coastal Venezuela (along the Aragua coast between Turiamo Bay and Puerto Colombia). We used the most recent data available: dolphins identified by unique dorsal fin marks...
Cobarrubia-Russo, Sergio; Barber-Meyer, Shannon; Barreto, Guillermo R.; Molero-Lizarraga, Alimar Exposure to domoic acid is an ecological driver of cardiac disease in southern sea otters
Harmful algal blooms produce toxins that bioaccumulate in the food web and adversely affect humans, animals, and entire marine ecosystems. Blooms of the diatom Pseudo-nitzschia can produce domoic acid (DA), a toxin that most commonly causes neurological disease in endothermic animals, with cardiovascular effects that were first...
Moriarty, Megan E; Tinker, M Tim; Miller, Melissa; Tomoleoni, Joseph; Staedler, Michelle M.; Fujii, Jessica A.; Batac, Francesca I.; Dodd, Erin M.; Kudela, Raphael M.; Zubkousky-White, Vanessa; Johnson, Christine K. User Guide: Creating a WHISPers morbidity/mortality event
A step-by-step guide to “put a dot on the WHISPers map” by creating an event. Available to users assigned Partner User, Partner Manager, and Partner Administrator roles.
Miller, Kimberli J. Eroding Cascadia—Sediment and solute transport and landscape denudation in western Oregon and northwestern California
Riverine measurements of sediment and solute transport give empirical basin-scale estimates of bed-load, suspended-sediment, and silicate-solute fluxes for 100,000 km2 of northwestern California and western Oregon. This spatially explicit sediment budget shows the multifaceted control of geology and physiography on the rates and processes of...
O'Connor, Jim E.; Mangano, Joseph F.; Wise, Daniel R.; Roering, Joshua R. Upland burning and grazing as strategies to offset climate-change effects on wetlands
Wetland ecosystems perform a multitude of services valued by society and provide critical habitat for migratory birds and other wildlife. Despite their importance, wetlands have been lost to different local, regional, and global drivers. Remaining wetlands are extremely sensitive to changing temperature and precipitation regimes. Management of...
McKenna, Owen P.; Renton, David A.; Mushet, David M.; Edward S. DeKeyser Thermal constraints on energy balance, behaviour and spatial distribution of grizzly bears
1. Heat dissipation limit theory posits that energy available for growth and reproduction in endotherms is limited by their ability to dissipate heat. In mammals, endogenous heat production increases markedly during gestation and lactation, and thus female mammals may be subject to greater thermal constraints on energy expenditure than males. Such...
