Question
It's not related to this tournament, but NASA's new PACE satellite is named for using optical spectroscopy to study the "phyto" type of these organisms. For 10 points each:
[10e] Name this broad group of aquatic organisms that are a major food source for krill and baleen whales.
ANSWER: plankton [or plankters; accept phytoplankton]
[10m] The PACE satellite's HARP2 polarimeter observes these atmospheric suspensions. These substances scatter sunlight, increasing the Earth's albedo.
ANSWER: aerosols [prompt on colloids or particulate matter or PM]
[10h] The PACE satellite is part of NASA's Earth Observing System, which employs techniques from this field. Topographic maps made with LiDAR ("LIE-dar") exemplify this field's goal of studying the Earth via emitted and reflected radiation.
ANSWER: remote sensing [accept active remote sensing]
