- Data Science
Background:
- Great Lakes ice cover significantly impacts North American climate, weather, economy, and ecology.
- Long-term ice cover data collection began in 1973 by multiple agencies.
- Previous datasets required upgrades in spatial and temporal resolution to meet evolving user needs.
Purpose of the Study:
- To reprocess and standardize historical Great Lakes ice cover data.
- To generate a consistent, accessible daily gridded ice cover dataset.
- To improve the usability of long-term ice cover records for research.
Main Methods:
- Reprocessing of historical Great Lakes ice cover data.
- Generation of daily gridded data at 1.8km resolution.
- Application of Nearest Neighbor Search for spatial interpolation and linear interpolation with categorization for temporal interpolation.
Main Results:
- A harmonized, daily gridded Great Lakes ice cover dataset with 1.8km resolution was generated.

01:50Global Climate Change
28.3K
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.

11.9K
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...

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...

01:21Isochoric and Isobaric Processes
4.0K
A thermodynamic process that occurs at constant volume is called an isochoric process. According to the first law of thermodynamics, heat supplied or removed from the system is partially utilized to perform work and change the internal energy of the system. However, in an isochoric process, the volume remains constant. Hence, the work done by the system is zero. Therefore, the exchange of heat changes the internal energy of the system only.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
