1 00:00:00,020 --> 00:00:00,730 2 00:00:00,750 --> 00:00:03,040 The oceans are responding to Earth's changing climate 3 00:00:03,060 --> 00:00:06,080 in ways that we are only beginning to understand. 4 00:00:06,100 --> 00:00:08,050 Given that phytoplankton are responsible 5 00:00:08,070 --> 00:00:10,580 for over half of the oxygen we breathe 6 00:00:10,600 --> 00:00:13,180 and form the base of the marine food chain, 7 00:00:13,200 --> 00:00:14,900 it is critical to understand 8 00:00:14,920 --> 00:00:18,480 how they are responding to these climate forcings as well. 9 00:00:18,500 --> 00:00:21,080 NASA has been using satellites, aircraft, and ships 10 00:00:21,100 --> 00:00:22,540 to study the biology of our oceans 11 00:00:22,560 --> 00:00:24,300 for over three decades. 12 00:00:24,320 --> 00:00:28,350 This combined data set provides an unprecedented opportunity 13 00:00:28,370 --> 00:00:32,400 to study oceanic climate change on the scale of decades. 14 00:00:32,420 --> 00:00:35,647
