USGS Benchmark Glacier Mass Balance and Project Data

Emily H Baker, Christopher J Mcneil, Louis Sass, Erich H Peitzsch, Erin N Whorton, Caitlyn E Florentine, Adam M Clark, Zachary S Miller, Daniel B Fagre & Shad R O'Neel
Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield Research Program (JIRP; Pelto et al., 2013). Direct field measurements of point glaciological data...

Sampling focused on Cinnabar Creek, which flows through the Cinnabar mine site, and Sugar Creek, with additional sites selected to place the data into...

Site-specific Protocol for Monitoring of Waterbirds Sequoyah National Wildlife Refuge

P.M. Schmidt, C.L. Lalonde, K.M. Linner, B.A. Grisham & W.C. Conway
The site-specific protocol for monitoring of waterbirds for Sequoyah National Wildlife Refuge (NWR) is based on the national protocol framework for the Integrated Waterbird Management and Monitoring Approach for Nonbreeding Waterbirds (Loges et al. 2015) [https://ecos.fws.gov/ServCat/Reference/Profile/83678]. For this survey, we define “waterbirds” as including waterfowl, cranes, long-legged wading birds, and shorebirds. The purpose of this refuge-specific protocol is to estimate temporal patterns of abundance of migrating and wintering waterbirds at the refuge in accordance with...

Site-specific Protocol for Monitoring White-tailed Deer Using Infrared Triggered Cameras Sequoyah National Wildlife Refuge

Paige Schmidt, Christina Lalonde, Jeremy Edwardson & Sarah Lehnen
White-tailed deer (Odocoileus virginianus; hereafter, deer) are a common species found throughout North America. Because deer management occurs at a localized scale, reliable estimates of population sex and age ratios are necessary to set hunt quotas and track deer population trends over time. The most widely-used deer survey techniques have been criticized in recent years for being biased. One alternative is the use of infrared camera traps. This protocol was developed to assist Sequoyah National...

Tabular Dataset: A BIOENERGETIC MODEL USED TO EVALUATE MANAGEMENT STRATEGIES FOR WINTERING WATERFOWL AT SEQUOYAH NATIONAL WILDLIFE REFUGE, VIAN, OKLAHOMA

Dustin Taylor, Paige Schmidt & William P. Johnson
A primary focus of Sequoyah National Wildlife Refuge (SNWR) is to provide habitat and foraging opportunities for waterfowl and other wetland dependent species. SNWR currently meets this objective by providing wetland and agricultural habitat. Wetland restoration and enhancement projects have occurred in recent years, with the intent to sustain healthier and more diverse waterfowl and wildlife populations. However, the relationship between habitat and food availability relative to waterfowl presence has yet to be quantified. This...

River Channel Survey Data, Redwood Creek, California, 1953-2013

Mary Ann Madej, Vicki Ozaki, Rachel Truesdell, Cristiana I Falvo, Kyle D Enns, Tara M Bell, Anthony L Everette & John L Faundeen
Dr. Richard Janda of the USGS began a channel monitoring program in Redwood Creek in northern coastal California in 1973. The USGS continued this work through 2013, when the Research Geologist, Dr. Mary Madej retired. This effort produced 40 years of channel change data in rivers that were disrupted by severe erosion following timber harvest of old-growth redwood forests, a portion of the program's data (plus 1953 data) has been preserved in this data release....

Aquifer recharge and susceptibility in New Hanover County, North Carolina

Dominick J. Antolino
The objective of this study is to delineate areas of primary groundwater recharge for the surficial, Castle Hayne, and Peedee aquifers in New Hanover County in order to determine the susceptibility of the local drinking-water aquifers. Areas of high susceptibility would coincide with groundwater recharge areas, likely where the Castle Hayne and Peedee aquifers are unconfined and directly connected with shallow surficial sands, as well as developed coastal areas prone to saltwater intrusion. Determining areas...

Sequoyah National Wildlife Refuge waterfowl land cover and habitat classification using SPOT-5 imagery

Steven Sesnie, Dustin Taylor & Paige Schmidt
Developing effective habitat conservation and management strategies. The relationship between available habitat and waterfowl numbers obtained from aerial survey transects is not well studied. To determine these relationships, multispectral SPOT-5 satellite imagery acquired for Sequoyah National Wildlife Refuge close to the time of waterfowl surveys was used to map habitat conditions. Robust Random Forest classification trees were used to model 16 land cover types using 416 reference locations collected in the field or derived from...

Data release for Food-web structure canyon- and slope-associated fauna revealed by stable isotopes

Amanda W. Demopoulos, Jennifer P. McClain-Counts, Steve W Ross, Sandra Brooke & Michael Rhode
The primary objective of this study was to assess deepsea food web structure and trophic niches in Baltimore and Norfolk canyons, the adjacent slopes, and chemosynthetic seeps along the mid-Atlantic margin using stable isotope analyses (SIA) and isotope niche width analysis. We hypothesized that the isotopic compositions of canyon versus slope fauna would be distinct, given differences in the physics and chemistry of the canyons and slopes and resulting quality and quantity of the organic...
