Field Data Collected 2018 to Document Human-induced Gorge Incision at The Kink (Fortymile River, Alaska) Field Data Collected 2018 to Document Human-induced Gorge Incision at The Kink (Fortymile River, Alaska)
This dataset is comprised of four tables containing channel survey cross section data, field observations including channel width and bank material, measured surface water velocity, and alluvial grain size data collected along the North Fork Fortymile River near a man-made meander cutoff called The Kink. The data release also contains eight field photos used to obtain grain size...
Marine Corps Base Hawaii Oahu Hawaiian Hoary Bat Acoustic Data 2019-2021 Marine Corps Base Hawaii Oahu Hawaiian Hoary Bat Acoustic Data 2019-2021
Acoustic sampling for presence of the endangered Hawaiian hoary bat (Lasiurus semotus, also known as Aeorestes semotus) was conducted at 17 stations across four Marine Corps Base Hawaii (MCBH) properties on O‘ahu Island, Hawai‘i. Bats were confirmed as present at all properties; MCBH K?ne?ohe Bay on M?kapu Peninsula, Marine Corps Training Area Bellows (MCTAB) in Waimanalo, Camp H.M...
Lake Ontario April Prey Fish Bottom Trawl Survey, 1997-2021 Lake Ontario April Prey Fish Bottom Trawl Survey, 1997-2021
This data release includes Lake Ontario prey fish data including species captured, relative abundance, spatial distribution, size structure, and age data from the April or spring prey fish bottom trawl survey, 1997 and 2021. Data from 1997 - 2015 are from U.S. waters of Lake Ontario while data from 2016 - 2021 include both U.S. and Canadian waters of Lake Ontario. Details about the...
Soil microbes surrounding native and non-native Phragmites australis in the Great Lakes and East Coast of the United States (2015-2017 survey) Soil microbes surrounding native and non-native Phragmites australis in the Great Lakes and East Coast of the United States (2015-2017 survey)
To determine the differences in soil microbial community composition between native and non-native lineages of Phragmites, we sampled soils from eight sites in the Great Lakes basin where populations of native and non-native Phragmites co-occurred. In addition, we included samples of soils from 27 populations of Phragmites across the Gulf of Mexico and Atlantic Coasts of the US. Samples...
Lidar-derived digital elevation models in Clarksburg, MD representing the years 2002, 2008, 2013, and 2018 Lidar-derived digital elevation models in Clarksburg, MD representing the years 2002, 2008, 2013, and 2018
This is a collection of 3 ft resolution digital elevation model derived from light detection and ranging (lidar). Lidar was collected in 2002, 2008, 2013, and 2018. Coverage includes a portion of Clarksburg, Maryland, focused around the Clarksburg Special Protection Area (CSPA). Overall extent varies between each dataset, but all digital elevation models are aligned together with...
Ephemeral channel heads and digital elevation models used to extract stream networks in Clarksburg, MD (ver. 2.0, October 2021) Ephemeral channel heads and digital elevation models used to extract stream networks in Clarksburg, MD (ver. 2.0, October 2021)
This dataset describes the location of channel heads survyed in two headwater watersheds in Clarksburg, Montgomery County, Maryland, and the digital elevation models derived from light detection and ranging (lidar) covering the two watersheds. The digital elevation models were used to derive topographic attributes used to delineate drainage networks that were then assessed for accuracy...
