The Science Behind Earth’s Flat Sea Level: An Exploration of Earth Observation Data.
Earth ObservationThe concept of sea level Sea level is the average height of the ocean surface. Because sea level is determined by the Earth’s gravity and rotation, it is not a flat surface. The shape of the sea surface is affected by many factors, including temperature, salinity, and ocean currents. The Moon’s gravitational pull also causes

Why is the ρστ absorption band named after ρ, σ, and τ? An Earth Observation Perspective
Earth ObservationThe ρστ absorption band, also known as the atmospheric window, is a spectral region in the electromagnetic spectrum where the Earth’s atmosphere is relatively transparent to incoming solar radiation. This region is characterized by three atmospheric gases: ρ (rho), σ (sigma), and τ (tau), which are responsible for absorbing radiation in this region. The ρστ

Investigating the Invasive Potential of New Guinea Snakes: A Geobiological Analysis
Earth ObservationNew Guinea, the second largest island in the world, is home to a rich and diverse array of snake species. However, the potential for some of these snakes to become invasive in other parts of the world has raised concerns among researchers and conservationists. Invasive species are known to cause significant ecological and economic damage,

Volcano in ocean?
Earth ObservationAsked by: Brian Barber Is there a volcano in the ocean? Most of these volcanoes are thousands of feet deep, and difficult to find. But in May of 2009, scientists captured the deepest ocean eruption ever found. Nearly 4000 feet below the surface of the Pacific Ocean – in an area between Samoa, Fiji and
