The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2008-2022. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation.The boundary was delineated by the Inte

This dataset contains observations of snow and firn density and stratigraphy from Site EC on Wolverine Glacier. Site EC is located in the accumulation zone on the northwest flank of the upper glacier at 1350m. Cores were recovered using a FELICS corer to approximately 25m depth at the end of the accumulation season and the end of ablation season starting in 2016. Additional cores were drilled thro

This dataset includes tables related to macroinvertebrate collections in streams and springs of the 1002 region of the Arctic National Wildlife Refuge in northeastern Alaska. Macroinvertebrates were collected using kicknets and driftnets in April and August with the goal of comparing populations to those sampled from the same water bodies by the USGS in the 1970s.

The 1966-2022 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly 24.5 miles

Subadult and smolt behavioral data were compiled by Ali Mokdad from Trevor Pitcher's lab at the University of Windsor, Ontario, Canada. Data are comprised of fish reactions in choice flume video data (attractance/avoidance) collected by Jeremy Kraus at Tunison Lab of Aquatic Science, August 2021 and February 2020 respectively. Atlantic salmon were exposed/not exposed to imprinting chemical (morpho

Observations of irrigated agricultural land within the Willcox Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification twice in 2022; crop verification occurred first on May 17th and again on August 26th. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2021 imagery for Arizo

We include planktic and benthic foraminifer census data tables from the Paleocene-Eocene sections of South Dover Bridge and Mattawoman Creek-Billingsley Road coreholes.

Fern Cave in Jackson County, Alabama is the longest and deepest cave in Alabama with over 15 miles of cave passages and 536 feet of depth. The cave is cooperatively managed by the U.S. Fish and Wildlife Service and the Southeastern Cave Conservancy. At least three different streams flow through the cave including the Surprise, Lower North, and Bottom Cave streams. Two of these streams, Lower North

Dye tracing investigations were conducted in Cades Cove and Tuckaleechee Cove, two carbonate fensters in the western Great Smoky Mountains. These investigations were conducted as part of a two-year study examining the karst hydrology in the carbonate fensters. Main objectives of the dye tracing investigations were to determine resurgences for cave systems, delineate recharge areas for major spring

This data release consists of four datasets which were used for evaluating winter drawdown (WD) lakes to follow the Massachusetts general WD guidelines. The first dataset ("Water level observations.csv") provides water level monitoring data of 21 (18 WD and 3 non-WD) recreational lakes in Massachusetts from 2014 to 2018. The water levels were measured by paired nonvented pressure transducers (HOBO

The U.S. Army Corps of Engineers (USACE) and the Nature Conservancy developed the Sustainable Rivers Program (SRP) as a collaborative environmental flows program to identify, refine, and implement environmental strategies at select USACE dams. The SRP was introduced to the Willamette Basin, Oregon, in 2007 through a series of environmental flow workshops, which led to stakeholder generated environ

This dataset includes details of loggerhead and green turtles captured and satellite tagged between 2009 and 2021; the turtles presented here have tracking days within Biscayne National Park. A subset of turtles was captured within Biscayne National Park, whereas others were tracked to the study site, and tagged elsewhere. The dataset contains information related to satellite tracking (e.g., track
