Iceberg Antarctica sheeding ice 1500

a driver of global sea level rise

FROM THE ARTICLE “A New Map is the Best View Yet of How Fast Antarc­tica is Shed­ding Ice” by Maria Tem­ming for Sci­ence News (Au­gust 5, 2019): “A new map based on satel­lite radar data re­veals the ve­locity of ice flow across Antarc­tica from areas of high el­e­va­tion to the coasts. In­land ice moves in­cred­ibly slowly—much of it plods along at fewer than 10 me­ters per year. Closer to the ocean, ice can travel hun­dreds to thou­sands of me­ters per year.”

“Ice melting off the con­ti­nent is al­ready known to be a driver of global sea-level rise,” notes Temming.“In 2021, NASA and the In­dian Space Re­search Or­ga­ni­za­tion plan to launch a satel­lite that will gather enough data to up­date this map every few months, al­lowing sci­en­tists to better mon­itor how ice flow across Antarc­tica changes as the cli­mate changes.”

A map that re­veals the ve­locity of ice flow across Antarc­tica is in­cluded in the ar­ticle.
