Suzette Kimball, director of USGS. However as Kimball explains, the EMU job is a significant advance in the quest to comprehensively map the entire ocean. "This quickly accessible map will act as a fresh resource for enhancing our understanding of the ocean's structureits salinity, temperature, oxygen levels, and nutrientsin countless locations," she said.

Each unit is a physically and chemically unique area of the ocean identified by six variables: temperature, salinity, liquified oxygen, nitrate, phosphate, and silicate. While GIS has been utilized time and once again to map the 2D surface area of the ocean, in addition to the 2D seafloor, this is among the very first usages of the technology to envision, identify, and analyze the 3D volumetric area between the surface and the bottom of the sea on a worldwide scale.

The EMUs are made up of a point mesh structure of around 52 million global measurements of 6 key variables (collected over a 50-year duration) that represent the physical and chemical properties of the ocean and are more than likely to affect how marine plants and animals react to their environment. As soon as this mesh was produced, the team applied extensive k-means analytical clustering to group together locations with comparable homes.

With the worldwide EMU map, there is now clinical assistance for marine spatial planning and management (to accommodate the various usages of the ocean, from industrial fishing and shipping to entertainment), developing brand-new marine safeguarded locations, and understanding the effects of climate change and other disturbances on all kinds of environments.

Teachers and students can utilize the Explorer app, complimentary of charge, to view 3D ocean information both in the class and in the field, as it is planned to improve laboratory jobs and field exercises.  Check it Out  can be quickly viewed in the Ecological Marine Unit Explorer. Dealing with the EMUs extends far beyond the classroom too.

Interest in the EMUs is significant. The project was initially commissioned by the Group on Earth Observations (GEO), an intergovernmental partnership that intends to open access to earth observation information to help people around the globe make much better decisions, so the results were constantly meant to be shared extensively.
