Rising Waters: How NASA is Monitoring Sea Level Rise
WebThe geoid is a model of global mean sea level that is used to measure precise surface elevations. A depiction of the United States geoid. Areas in yellow and orange have a slightly stronger gravity field as a result of the … WebSea level is primarily measured using tide stations and satellite laser altimeters. Tide stations around the globe tell us what is happening at a local level—the height of the water as measured along the coast relative … WebThe ARGO buoys measure temperatures at various depths. Since warmer water is less dense than is cooler water, rising ocean temperatures are a key contributor to sea level rise, about 1/3 of the total. Yet other measurements come from space. The remaining 2/3 of sea level rise results from added mass to the oceans. oteh footballer
