dr. jason amundson calculate how much melted ice is flowing into the ocean. >> when the glaciers are actually in retreat, the one thing they y do is they contrtre to sea level rise, but they also affect atmospheric circulation patterns, which propagates downstream. it affects other things. the changes in the amount of freshwater runoff into the ocean, which will affect the ocean properties, which could affect the marinine life. >> > the globalal sea levelel ig to rise, and it will rise by varying amounts depending on where you are in the world, and the contribubution from glacie is like to o beignififint. >> diggining sn pitits s beenen useful for almost 60 years on the juno icefield, but when these snow pits are paired with new ground-breaking technologies, the science becomes even m more successful. salvatore candela is using a powerful ground-penetratating radar, or gpr as it's known, to gett information from the vastt areas between snow pipits using the pits thememselves as a refeference for hihis readings. >> the diggingng of pits and usg ground-penetrtrating radar realy tieses well toge
