Summary
This study provides accessible datasets for five Global Plate Models, enabling researchers to easily retrieve paleocoordinates for geological and paleontological samples without specialized software. These resources facilitate consistent paleogeographic reconstructions.
Area of Science:
- Earth Sciences
- Paleogeography
- Geophysics
Background:
- Global Plate Models are crucial for reconstructing past geographic positions of geological and paleontological samples.
- Retrieving accurate paleocoordinates using these models can be complex due to variations in model complexity, coverage, and reference frames.
- Selecting the appropriate Global Plate Model for specific research questions is essential.
Purpose of the Study:
- To document and provide access to reconstruction datasets for five Global Plate Models.
- To offer 'true' paleolatitudes for global grids reconstructed at one-million-year intervals throughout the Phanerozoic (540-0 Ma).
- To simplify the process of obtaining paleocoordinates for Earth Science research.
Main Methods:
- Compiled reconstruction datasets for five Global Plate Models.
- Standardized output to the paleomagnetic reference frame.
- Generated global grids at one-million-year intervals for the Phanerozoic.
Main Results:
- Provided static, documented datasets for five Global Plate Models.
- Enabled users to look up paleocoordinates via simple indexing.
- Facilitated consistent paleocoordinate generation and evaluation of inter-model differences.
Conclusions:
- The released datasets simplify paleocoordinate retrieval for Earth Scientists.
- Consistent and documented paleocoordinate data aids research reproducibility.
- These resources allow for comparative analysis of different Global Plate Models.

01:50Global Climate Change
24.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

6.0K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

02:56The Fossil Record
25.1K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
