The Soil Ecosystem02:23

The Soil Ecosystem

19.6K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Global Climate Change01:50

Global Climate Change

24.0K
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.

Geoid and Ellipsoid01:28

Geoid and Ellipsoid

22
The Earth's shape is best described as an ellipsoid, a slightly flattened sphere created by rotating an ellipse around its minor axis. This flattening results in the polar axis being about 21 kilometers shorter than the equatorial axis. In contrast, the geoid represents the Earth's gravitational shape and aligns with the mean sea level (MSL). The geoid is an irregular equipotential surface where gravity is perpendicular at every point. Variations in Earth's mass distribution cause geoid...

Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

20
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...

Meridians01:28

Meridians

278
In surveying, meridians are vital reference lines to measure directions and establish accurate land orientations. Meridians run from the north to the south poles, providing a stable framework for angular measurements and mapping. Meridians are fundamental in survey design, with the primary types being astronomic, magnetic, and assumed meridians. Each type offers distinct benefits and limitations, selected based on the project's scale and precision needs.The astronomic meridian is aligned with...

Apparent Weight and the Earth's Rotation01:28

Apparent Weight and the Earth's Rotation

3.5K
Since all objects on the Earth's surface move through a circle every 24 hours, there must be a net centripetal force on each object, directed towards the center of that circle. The points of the north and south poles are the only exception to this rule.
For an object on the Earth's equator, the net centripetal force that accounts for its rotation is the Earth's pull towards its center, or the weight minus the normal force that prevents it from piercing into the Earth's surface....

Area of Science:

  • Earth System Science
  • Environmental Science
  • Human Geography

Background:

  • Human activities extensively modify Earth's land and marine environments, leading to significant environmental degradation.
  • Studying the spatial dynamics between human systems and Earth systems is challenging due to fragmented data.

Purpose of the Study:

  • To present the Surface Earth System Analysis and Modeling Environment (SESAME) Human-Earth Atlas, a comprehensive spatial dataset.
  • To facilitate data discovery and modeling of human-Earth system dynamics by integrating diverse variables.

Main Methods:

  • Development of a spatial dataset with hundreds of human and non-human Earth system variables on common grids (1- and 0.25-degree resolution).
  • Utilization of machine learning for data interpolation in undersampled areas.
  • Downscaling national-level human system variables to spatial grids using dasymetric mapping, accounting for boundary changes.

Main Results:

  • The SESAME Human-Earth Atlas provides a unified spatial framework for diverse Earth system data.
  • The Atlas integrates raster, point, line, polygon, and tabular data onto standardized spatial grids.
  • Variables are structured by common spheres and many resolve changes over time.

Conclusions:

  • The Human-Earth Atlas addresses data fragmentation, enabling more robust spatial analysis of human-Earth system interactions.
  • This resource is crucial for advancing research on environmental change and sustainable development.
  • The Atlas supports improved modeling and understanding of the complex relationships shaping our planet.
