Suzette Kimball, director of USGS. But as  Also Found Here  explains, the EMU job is a substantial action forward in the mission to adequately map the whole ocean. "This quickly accessible map will function as a fresh resource for enhancing our understanding of the ocean's structureits salinity, temperature, oxygen levels, and nutrientsin millions of places," she stated.

Each unit is a physically and chemically unique location of the ocean differentiated by 6 variables: temperature, salinity, dissolved oxygen, nitrate, phosphate, and silicate. While GIS has been utilized time and again to map the 2D surface of the ocean, in addition to the 2D seafloor, this is one of the very first uses of the innovation to envision, identify, and analyze the 3D volumetric area between the surface area and the bottom of the sea on a worldwide scale.

The EMUs are composed of a point mesh structure of approximately 52 million global measurements of six crucial variables (gathered over a 50-year duration) that represent the physical and chemical residential or commercial properties of the ocean and are probably to impact how marine plants and animals react to their environment. When this mesh was created, the group applied strenuous k-means statistical clustering to group together areas with similar homes.

With the global EMU map, there is now scientific assistance for marine spatial planning and management (to accommodate the numerous uses of the ocean, from business fishing and shipping to leisure), creating brand-new marine secured locations, and understanding the results of climate modification and other disturbances on all kinds of ecosystems.

Educators and students can utilize the Explorer app, free of charge, to view 3D ocean data both in the class and in the field, as it is meant to enhance laboratory jobs and field workouts. The EMUs can be easily seen in the Ecological Marine System Explorer. Dealing with the EMUs extends far beyond the classroom as well.

Interest in the EMUs is far-reaching. The job was initially commissioned by the Group on Earth Observations (GEO), an intergovernmental collaboration that intends to open access to earth observation information to help people worldwide make better choices, so the results were always planned to be shared extensively.
