Short-Lived Radioisotope (Excess Pb210) Measurements From Sediment Cores Collected Throughout The Gulf Of Mexico From 2010-11-07 To 2017-07-20, Patrick Schwing, David Hollander Oct 2018

Short-Lived Radioisotope (Excess Pb210) Measurements From Sediment Cores Collected Throughout The Gulf Of Mexico From 2010-11-07 To 2017-07-20, Patrick Schwing, David Hollander

C-IMAGE data

This dataset includes baseline short-lived radioisotope measurements from sediment cores collected throughout the Gulf of Mexico. Samples were analyzed by gamma spectrometry with High-Purity Germanium (HPGe) gamma-ray detectors (Canberra Coaxial Planar configuration) for total 210Pb (46.5 keV), 214Pb (295 keV and 351 keV), and 214Bi (609 keV) activities. The mean activity of the 214Pb (295 keV), 214Pb (351 keV), and 214Bi (609 keV) was used as a proxy for 226Ra activity and therefore the supported 210Pb that is produced in situ. The reported excess 210Pb (210Pbxs) is the difference of the total 210Pb and the supported 210Pb.

Dataset For: Tracking An Oil Tanker Collision And Spilled Oils In The East China Sea Using Multisensor Day And Night Satellite Imagery, Shaojie Sun Mar 2018

Dataset For: Tracking An Oil Tanker Collision And Spilled Oils In The East China Sea Using Multisensor Day And Night Satellite Imagery, Shaojie Sun

C-IMAGE data

In this dataset, we used a multi-sensor day and night satellite approach to track the SANCHI oil tanker collision and oil spill event in January 2018 in the East China Sea. The drifted on fire oil tanker was tracked by Visible Infrared Imaging Radiometer Suite (VIIRS) Nightfire product and Day/Night Band (DNB) imagery. Such pathway and locations were also reproduced with a numerical model, with RMS error of < 15 km. MultiSpectral Instrument (MSI) optical imagery during daytime shows smokes on 13 January 2018, further confirms the drifted tanker location. MSI imagery after 4 days of the tanker’s sinking (18 January 2018) reveals oil on the ocean surface to the east and northeast of the tanker sinking location. This combination of all available remote sensing and modeling techniques can provide effective means to monitor marine accidents and oil spills to assist event response.

Evaluation Of Diet Matrix Uncertainty For The Atlantis Model, Cameron Ainsworth Mar 2018

Evaluation Of Diet Matrix Uncertainty For The Atlantis Model, Cameron Ainsworth

C-IMAGE data

We conducted 1000 Atlantis simulations, using permutated diet matrices created by drawing from a beta distribution that represented uncertainty in predator diet. We also employed a statistical emulator which simulates the production of many more Atlantis runs than could be achieved through numerical simulation. This dataset includes 3 products: statistical emulator output, diet matrices, and Atlantis simulations. These are each contained in their own zip file.

Trace Metals And Minor Elements In Southern Gulf Of Mexico Sediments Following The Ixtoc Marine Oil Blow Out Event, 2015, David W. Hastings, Thomas Bartlett

C-IMAGE data

Our objective is to compare the impact of two marine oil well blowouts on surface sediments in the Gulf of Mexico: the recent 2010 DWH blowout in the Northern Gulf with the Ixtoc blowout in 1979/80 in the Southern Gulf. A suite of trace and minor elements (V, Cr, Mn, Fe, Co, Ni, Cu, Sr, Cd, Mo, Ba, Re, and U) some of which are sensitive to changes in sedimentary redox conditions, was analyzed in bulk surface sediments; that data is presented here. Sediment cores were collected in the SE GoM on a research cruise on the R/V Justo Sierra …
