The IEDA data facility’s mission is to support, sustain, and advance the geosciences by providing data services for observational geoscience data from the Ocean, Earth, and Polar Sciences.

IEDA systems serve as primary community data collections for global geochemistry and marine geoscience research and support the preservation, discovery, retrieval, and analysis of a wide range of observational field and analytical data types. Our tools and services are designed to facilitate data discovery and reuse for focused disciplinary research and to support interdisciplinary research and data integration.

The Space team has made the following datasets and collections publicly available. You must be a logged-in member of the Space to access all the datasets and collections.

Processed ship-based Navigation Data acquired during the Laurence M. Gould expedition LMG0209 (2002)

Abstract: This data set was acquired with a ship-based Navigation system during Laurence M. Gould expedition LMG0209 conducted in 2002 (Chief Scientist: Dr. Fred Taylor). These data files are of MGDS:Nav format and include Primary Navigation data and were processed after data collection. Data were acquired as part of the project(s): The Scotia Arc GPS Project: Focus on the Antarctic Peninsula and South Shetland Islands and AMS Radiocarbon Chronolgy of Glacier Fluctuations in the South Shetland Islands During the Last Glacial/Interglacial Hemicycle: Implications for the Role of Antarctica in Global Climate Change, and funding was provided by NSF grant(s): ANT01-26472 and ANT98-14349. http://dx.doi.org/10.1594/IEDA/311881

Steens Basalt Sr, Nd, Pb, Hf, Os, and O Isotopic Compositional Data

Abstract: This dataset presents analyses of Sr, Nd, Pb, Hf, Os, and O whole rock and mineral isotopic compositions for a suite of basalts from the type section of the Steens Basalt at Steens Mountain in southeast Oregon, and other regional outcrops of the Steens Basalt. The Steens Basalt (~16.9 Ma) is the oldest and most mafic member of the Columbia River Basalt Group (CRBG), the world's youngest continental flood basalts. These data help further characterize the three-stage evolution of the Steens Basalt magmatic system, by elucidating mantle source components that contributed to magma generation, as well as crustal processes that modified the magmas during ascent through and storage within the crust prior to eruption.; Other Description: Moore, N.E., Grunder, A.L., Bohrson, W.A., Carlson, R.W., Bindeman, I.N.

Processed multi-channel seismic data on the Juan de Fuca Plate, from Juan de Fuca Ridge to Cascadia deformation front off Oregon and Washington, acquired during the R/V Marcus G. Langseth survey MGL1211 (2012)

Abstract: This dataset contains the time-migrated MCS data along two ridge-to-trench transects across the Juan de Fuca (JdF) plate, from Endeavour Ridge to offshore Washington state and from Axial Volcano to offshore Oregon state, and one 400 km-long trench-parallel transect extending from 44.3N to 47.8N acquired during the 2012 R/V Langseth survey. The seismic reflection images of the two ridge-to-trench transects reveal the crustal structure of the JdF plate, distribution and extent of faults across the plate interior as the crust ages and near the deformation front in response to subduction bending, and a series of distinctive, ridgeward-dipping (20-40 degrees) lower crustal reflections in ~6-8 Ma crust along both transects. The trench-parallel transect characterize the along-strike structural variations of the sediment section and the JdF plate prior to subduction, in particular the structures associated with propagator wakes, a seamount, and four major strike-slip faults.

Origin of Persistent Organic Pollutants in the Antarctic Atmosphere, Snow and Marine Food Web

Abstract: Many persistent organic pollutants (POPs), though banned in the U.S. since the 1970s, remain in the environment and continue to reach hitherto pristine regions such as the Arctic and Antarctic. The overall goals of this RAPID project are to better understand the remobilization of POPs from melting glaciers in the Antarctic, and their transfer into the food-web. Legacy POPs have characteristic chemical signatures that will be used ascertain the origin of POPs in the Antarctic atmosphere and marine food-web. Samples that were collected in 2010 will be analyzed for a wide range of legacy POPs, and their behavior will be contrasted with results for emerging contaminants. The intellectual merit of the proposed research combines (a) the use of chemical signatures to assess whether melting glaciers are releasing legacy POPs back into the Antarctic marine ecosystem, and (b) a better understanding of the food-web dynamics of legacy POPs versus emerging organic pollutants. The broader impacts of the proposed research project will include the training of the next generation of scientists through support for a graduate student and a postdoctoral scholar. As well, this work will result in a better understanding of the relationship between pollutants, trophic food web ecology and global climate change in the pristine Antarctic ecosystem. http://dx.doi.org/10.15784/600138
