Whales and Carbon Sequestration: Can Whales Store Carbon?

3/18/2024 - By fisheries.noaa.gov. The ocean captures about 31 percent of all carbon dioxide emissions, removing carbon from the atmosphere that would otherwise continue to trap heat and increase temperatures. Blue carbon, or carbon captured by ocean ecosystems includes: Carbon absorbed by aquatic plants, algae, and phytoplankton Carbon stored in the bodies of living animals… SEE MORE

Rising Sea Levels Increase Threat Of Arsenic In Drinking Water

3/17/2024 - By Kendra Pierre-Louis. (Bloomberg) —Rising seas due to climate change could exacerbate the threat of arsenic in drinking water, according to a study published in PLOS ONE in January. Researchers focused on arsenic in well water in Bangladesh, where up to 97% of the population relies on such water for drinking. Arsenic occurs naturally… SEE MORE

NOAA's National Geodetic Survey defines and manages the National Spatial Reference System — a consistent coordinate system that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States. In addition to a network of continuously operating reference stations supporting three-dimensional positioning activities (shown here), the reference system includes a network of permanently marked points; a consistent, accurate, and up-to-date national shoreline; and a set of accurate models describing dynamic, geophysical processes that affect spatial measurements.

NOAA Scientists are Revolutionizing How Heights & Elevations are Measured

3/15/2024 - By oceanservice.noaa.gov. Suppose you are buying a new home that is located near a river that routinely floods. During the buying process, you learn that you are required to have flood insurance. A step in the process of obtaining this insurance is to get a certified elevation of your new… SEE MORE
