The Age And Origin Of Precambrian Orthogneiss Of The Grouse Creek Block, Northern Utah And Southern Idaho, Skadi Kobe Dec 2020

The Age And Origin Of Precambrian Orthogneiss Of The Grouse Creek Block, Northern Utah And Southern Idaho, Skadi Kobe

Fall Student Research Symposium 2020

New geochronologic and isotopic analyses from the Grouse Creek block (GC) provide insight into the assembly of western Laurentia during the late Archean to Paleoproterozoic and establish the influence of the GC in the evolution of Yellowstone-Snake River Plain hotspot magmatism in the central Snake River Plain. The GC is primarily exposed in the Albion-Raft River-Grouse Creek metamorphic core complex of northern Utah and southern Idaho and includes a complex assemblage of orthogneiss, schist, amphibolite, and metasediments intruded by Oligocene plutons and overlain by Cenozoic sedimentary units. Many investigations of the GC have focused on the structural evolution of the …


Massachusetts Beach Grain Size And Slope Data, Jonathan Woodruff, Nicholas Venti, Stephen Mabee, Alycia Ditroia, Douglas Beach Oct 2020

Massachusetts Beach Grain Size And Slope Data, Jonathan Woodruff, Nicholas Venti, Stephen Mabee, Alycia Ditroia, Douglas Beach

Data and Datasets

This data repository contains grain size and beach face slope data from approximately 100 paired summer and winter transects collected along 18 separate beaches in southern New England. The study is focused to beaches of Massachusetts, which represents a particularly unique section of the Northeastern US coast in that it: 1) lies at the interface between New England’s paraglacial lowlands and Mid-Atlantic Coastal Plain, 2) spans both micro- and meso- tidal regimes, 3) encompasses a wide range of seasonally varying wave conditions, and 4) contains a diverse array of geomorphic and grain size characteristics. Between 2 and 10 intertidal transects …

Anthropogenically Expedited Transit Reduces Organic Carbon Loss In The Lower Mississippi River: Dataset, Zhixiong Shen, Brad E. Rosenheim, Torbjörn E. Törnqvist, Andreas Lang Jun 2020

Anthropogenically Expedited Transit Reduces Organic Carbon Loss In The Lower Mississippi River: Dataset, Zhixiong Shen, Brad E. Rosenheim, Torbjörn E. Törnqvist, Andreas Lang

College of Science Data Sets

This dataset presents data to investigate the change of organic carbon carried by the Lower Mississippi River (LMR) related to river engineering. The dataset includes (1) OSL data, (2) 14C data; (3) the channel centerline of the LMR in the 1970s, (4) the channel centerline of the LMR in 2019, and (5) the migration rates of the LMR between the 1970s and 2019.


Wrack & Ruin: A Tale Of Tortured Trees, John T. Van Stan Ii, Albertus Tyasseta, Siloy, Graphic Artist Jun 2020

Wrack & Ruin: A Tale Of Tortured Trees, John T. Van Stan Ii, Albertus Tyasseta, Siloy, Graphic Artist

School of Earth, Environment, and Sustainability Faculty Bookshelf

Here, we visit a community of trees living along the Georgia coast, just above the high tide line, on a little lump of sand called a "hammock." This hammock plant community is battered by a hurricane. The plants that survive soon realize that they have fallen prey to a hydrological torture wrack - one composed of the salty corpses of their neighboring marsh plants (Spartina alterniflora). This sci comic is based on the publication, "Wrack and ruin: Legacy hydrologic effects of hurricane-deposited wrack..." (https://doi.org/10.1088/2515-7620/ab9527).

Hudson River Estuary Tidal Marsh Sediment Data, Brian Yellen, Jonathan Woodruff Jan 2020

Hudson River Estuary Tidal Marsh Sediment Data, Brian Yellen, Jonathan Woodruff

Data and Datasets

This repository contains data from sediment cores collected at six tidal wetland complexes that are located within the Hudson River Estuary. The sites include Stockport Marsh, Esopus Delta, Tivoli North Bay, Tivoli South Bay, Vanderburgh Cove, and Iona Island Marsh. A variety of core collection tools and methods were used to collect uncompacted records, including gouge coring, Russian peat coring, and piston push coring, with the method determined by coring environment. The general workflow for cores included (1) splitting; (2) Itrax XRF scanning; (3) subsampling cores ~10 cm spacing; (4) drying and burning samples for percent water, organic, and mineral …

Dam Impoundments Sediment Mass – Tributaries To The Hudson River, Brian Yellen, Jonathan Woodruff Jan 2020

Dam Impoundments Sediment Mass – Tributaries To The Hudson River, Brian Yellen, Jonathan Woodruff

Data and Datasets

This repository contains data from sediment cores collected during 2017-2018 from 17 impoundments that are located on tributaries to the tidal portion of the Hudson River as part of a larger NERRs collaborative project entitled Dams and Sediment on the Hudson (DaSH). A companion dataset that contains sediment core data from Hudson tidal marshes is archived at UMass Scholarworks data repository. Sediment cores collected from impoundments behind dams were recovered via piston push coring, which tends to minimize compaction and be representative of true sediment thicknesses. The general workflow for cores included (1) splitting; (2) Itrax XRF scanning; (3) subsampling …
