Global sea level rise has been accelerating in recent decades, according to a new study based on 25 years of NASA and European satellite data.
The Earth's system exemplifies stability and change. Change and rates of change can be observed and quantified over very short or long periods of time and various spatial scales (e.g., from landscape level to global processes).
MND wants you to check out the new MND lesson plan, An Earth System View of Earthrise. Teachers who conduct the lesson in their classrooms and upload evidence of student work to our
Students will use coloring sheets to create a color coded model of El Niño. If the Data Literacy Map Cube is used with this, students should color their models first.
The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons. Earth's rotation, revolution around the sun, and tilt all play a role, as do the wind-driven ocean surface currents.
Salinity is key to studying the water cycle and ocean circulation, both of which are related to climate. Over decades, the amount of salt in ocean basins has been fairly stable. The water cycle operates on much faster time scales, however, causing changes in salinity patterns.
The Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) instrument aboard the Seastar satellite collected ocean data for more than a decade.
Turbulent storms churn the ocean in winter, adding nutrients to sunlit waters near the surface. Each spring this gives rise to massive blooms of phytoplankton. These microscopic plants harvest vital energy from sunlight through photosynthesis.
