Over the years
they added oceans of information and analytical tools on stocks, commodities, energy, options, real estate, currencies — you name it.
ICESat - 2 will
add to our understanding
of Arctic sea ice by measuring sea ice thickness from space, providing scientists more complete
information about the volume
of sea ice in the Arctic and Southern
oceans.
Scientists have recently observed major changes in these glaciers: several have broken up at the
ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount
of ice and water they discharge into the
ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also
adds freshwater to the
oceans, altering ecosystems and changing
ocean circulation and regional weather patterns.7 (See Greenland ice sheet hotspot for more
information.)
