Bioblitzes facilitate non-native fish tracking and interagency partnerships data

Pam Schofield
Maintaining up-to-date information on non-native organisms' distributions and species composition can be difficult, especially when species cross jurisdictional boundaries that require interagency coordination. Herein I report on the use of tools that have been used in Florida over the past seven years to assist with tracking of non-native fishes. Ten Fish Slams, where professional biologists and graduate students come together to sample an area for non-native fish, have been held since 2012, which have included...

LEAN-Corrected DEM for Suisun Marsh

Kevin J Buffington, Karen M Thorne, John Y Takekawa, Steve Chappell, Ted Swift, Cliff Feldheim, Anthony Squellati & Daniel K Mardock
Lidar-derived digital elevation models often contain a vertical bias due to vegetation. In areas with tidal influence the amount of bias can be ecologically significant, for example, by decreasing the expected inundation frequency. We generated a corrected digital elevation mode (DEM) for Suisun marsh using a modification of the Lidar Elevation Adjustment with NDVI (LEAN) technique (Buffington et al. 2016). GPS survey data (6912 points, collected across public and private land in 2018), Normalized Difference...

Many mineral commodities are now produced primarily or entirely outside of the United States, creating the potential for supply...

iTOUGH2-EOS7C model used to analyze multiphase flow and hydromechanical coupling in underpressured shale at the Bruce Nuclear Site, Ontario, Canada

Michael R. Plampin
Using iTOUGH2-EOS7C, a simple 1-D model was developed to represent a site in Ontario, Canada which is being considered for nuclear waste disposal. The site exhibits substantially underpressured water and potential evidence for gas phase methane within a thick section of sedimentary rocks. To investigate possible mechanisms for the development of the underpressure in a multiphase system, hydromechanical coupling during a glacial cycle was simulated with and without gas phase methane present. Results indicate that,...
