By Eric Lindstrom Almost everyone can imagine the bridge of a ship – from the movies, a tour of a ship, or maybe you are the master of your own vessel. It is the place where control of all ship operations is commanded. On the bridge of the Knorr, an officer and a seaman are […]
By Eric Lindstrom The complex job of managing the data from SPURS is daunting because of the number of different platforms and data streams that need to be logged and cross-calibrated. Overall, by NASA standards, we are dealing with relatively small quantities of data (Gigabytes) but there are many,many different sensors and platforms involved. The […]
By Eric Lindstrom Yi Chao is one of the “spiritual leaders” of our “dry” team in SPURS (those people who help from land). He is an ocean modeler in California who has been involved with Aquarius and SPURS for many years. He long ago decided to be on the dry team because of the seasickness […]
By Eric Lindstrom The SPURS work has renewed interest in the broader community in studying the ocean to better understand the global water cycle, heating and cooling of the oceans, and oceanic mixing. Julian Schanze of Woods Hole Oceanographic Institution/MIT is about to complete his Ph.D. in physical oceanography under the supervision of Ray Schmitt. […]
By Eric Lindstrom The thermosalinograph (TSG) on Knorr is a shipboard instrument for measuring temperature and salinity of the near surface water . It is situated in a lab and receives a flow of water taken in near the bow and piped out near the stern. It is quite an adventure going down to see […]
By Eric Lindstrom The Research Vessel Knorr is a fantastically capable oceanographic research vessel. She has traveled over 2 million miles and explored all the major oceans in her around 40 years of service. As a visiting oceanography research crew, we have our space on the ship, for which we have free run. We are […]
By Eric Lindstrom There are not many places in the open ocean that get their own special name as a “sea.” Most seas are what we call marginal seas – offshoots of the major ocean basins. The Sargasso Sea, as a vast track of the western subtropical North Atlantic Ocean is known, has a special […]
By Eric Lindstrom After several weeks of your following my postings from the field, I thought it would be good to tell you a little about myself. Maybe that will help explain the weird wanderings of the blog or the subject matters I choose to write about. Let’s start at the beginning: I grew up […]
By Eric Lindstrom From the shipboard perspective, all we really see of the sea is the surface. Of course we can see into the water a short way, right close to the ship, but not very far. The horizon is 360 degrees and the great dome of sky seems endless. Being that we are about […]
By Eric Lindstrom When we are doing work at sea, it hardly seems fair for NASA to hog the limelight. We are usually offering data from satellites, not ships, moorings, or gliders. There are partner agencies in the U.S. Government who make enormous contributions to the physical oceanography enterprise. In D.C., oceanographers know these agencies […]
