Education: Obtaining, Evaluating, and Communicating Information

Obtaining, Evaluating, and Communicating Information Scientists and engineers must be able to communicate clearly and persuasively the ideas and methods they generate. Critiquing and communicating ideas individually and in groups is a critical professional activity. Click on the icons (below right) to view other standards.

Sea surface salinity research has come a long way, initially being measured from ships and more recently with autonomous floats such as wave gliders and Argo. Beginning in the mid 1970s, satellites were launched into space to measure various oceanographic processes.
Discharge of the Mississippi River at Belle Chasse, LA

Dr. Gary Lagerloef uses data collected from NASA's Aquarius satellite to show ocean processes taking place in the Gulf of Mexico (September, 2011).
Measuring water depth from the International Space Station

In this clip, Dr. Eric Lindstrom gives viewers a comparison between early seagoing vessels and earth-observing satellites.
Mooring deployment

Dr. Tom Farrar dicusses how scientists design surface moorings to stay in one place in the middle of the ocean while simultaneously collecting data for up to one year at a time.
Carbon flux

Dr. Gary Lagerloef explains how understanding ocean salinity can help us to better understand human-induced global climate change.
Schematic of ARGO profile operation

Dr. Stephen Riser explains what an Argo float is and how it has increased scientists' knowledge of global ocean salinity since its implementation.
TOPEX/Poseidon satellite

Ocean-observing satellites are able to measure a variety of properties including weather, salinity, temperature, and ocean color. Dr. Eric Lindstrom talks about the evolution of these satellites and how they have progressed to give us more detailed views of the worlds oceans from space.
Map of average salinity from historical ship and buoy data

The freshwater cycle and the salinity cycle operate at very different time scales; as our freshwater cycle intensifies, this difference is becoming more significant for global climate change.
International space station

Dr. Eric Lindstrom talks about the connection between ocean-going vessels and ocean-observing satellites and how both are vital in learning more about how ocean circulation works and affects our planet.
Flux buoy locations

Surface moorings collect continuous data from a single point in the ocean. Dr. Tom Farrar explains the types of instrumentation often found atop one of these moorings.
The global water cycle

In this clip, Dr. Stephen Riser explains that ocean salinity is a way to better understand the global water cycle. Salinity plays a role in determining seawater density, which can determine where water travels throughout the oceans.
