The Salinity Processes in the Upper Ocean Regional Study (SPURS) represents the collaborative efforts between a diverse group of scientists spanning national and international borders, from multiple organizations. These include, but are not limited to, physical oceanography experts and climate scientists from NASA, researchers from the Woods Hole Oceanographic Institution, and research professors from The University of North Carolina, Wilmington, to name a few. Here we present two webinar series on the SPURS project - Ocean Thinking: Inside and Outside the Box and Seeking Salt: Measuring a Key Ingredient of Climate.
Ocean Thinking: Inside and Outside the BoxSeptember 17, September 24, and October 1, 2013
SPURS seeks to improve our understanding of the ocean - especially its role in the global water cycle. Join three SPURS scientists as they describe several ways of looking at the ocean in and outside of the SPURS "box" - by examining the motion of water due to density, the dynamics occurring at the skin of the ocean's surface down to depths of hundreds of meters, and attempting to determine the salt "budget" as a result of ocean processes.
It may be easy to think about studying the ocean by looking at a small section of it, but the reality is that water is constantly on the move. While highlighting his own research within the SPURS area, Julius demonstrates how the atmosphere affects the water cycle both on land and in the ocean, and how the movement of seawater plays a crucial role in our understanding global ocean circulation.
Changes In Latitude
Presented by Julius Busecke - Tuesday, September 17, 2013
Julius Busecke is a Graduate Research Assistant at Lamont-Doherty Earth Observatory, Columbia University. He received his B.Sc. from the University of Kiel, Germany in 2010.
The atmosphere is not the only thing that affects the ever-changing ocean. Using in-water measurement tools such as profiling floats, as well as satellite data from SMOS and Aquarius instruments during the SPURS mission cruises, Dr. Riser has examined salinity changes in the SPURS area from the surface of the water to the depths of the ocean. Ultimately, Dr. Riser is seeking to investigate long term changes – by using a combination of observations from above and below.
From Skin to Deep
Presented by Stephen Riser - Tuesday, September 24, 2013
Dr. Stephen Riser is a Professor in the School of Oceanography at the University of Washington. His primary interests are in the ocean's role in climate, and in deducing the general circulation of the ocean and ocean/atmosphere/ice interactions through direct observations of the ocean circulation. He is also increasingly thinking about the interactions between physical aspects of the ocean circulation and biogeochemical properties of the ocean.
Determining ocean salinity trends is not a simple task. With differences in the amount of water, heat, and salt constantly coming and going, as well as gradients across depth and latitude, it’s a challenging task to undertake. Dr. Farrar will share what data from a fixed mooring within the SPURS area can tell us about the overall "salt budget" for one of the saltiest parts of the world’s ocean.
Balanced Budget? Oh, Buoy!
Presented by Tom Farrar - Tuesday, October 1, 2013
Dr. Tom Farrar is an Associate Scientist at Woods Hole Oceanographic Institution. His research interests include air-sea interaction and exchange; dynamics and thermodynamics of the upper ocean; tropical dynamics and equatorial waves; oceanic internal waves and eddies; satellite oceanography; and ocean observing and instrumentation. These interests are pursued from an observational perspective using in situ observations, satellite observations, and, in some cases, laboratory and numerical models to test hypotheses and test or formulate simplified physical models that aid understanding.
Seeking Salt: Measuring a Key Ingredient of ClimateFebruary 26, March 5, and March 12, 2013
Everyone knows that the ocean is salty, but did you know that salt is essential to the recipe for our entire climate and life on Earth?
What is a sensor web, and how does it help SPURS? Dr. Eric Lindstrom takes us on engaging trip through salinity research and will reveal how ocean exploration has evolved over time. The SPURS team took part in an international collaborative effort to better understand this fundamental part of the ocean and climate system, and used a combination of approaches to investigate what's happening in the unique "ocean desert" of the North Atlantic.
From Sailing Ships to Satellites: Studying Salinity Through A Sensor Web
Presented by Dr. Eric Lindstrom - February 26, 2013
Dr. Eric Lindstrom is a Program Scientist in the Science Mission Directorate at NASA Headquarters in Washington D.C. He has degrees in Earth and Planetary Sciences from Massachusetts Institute of Technology (1977) and Physical Oceanography from the University of Washington (1983). His scientific interests include circulation of the ocean and air-sea exchange processes. Read more about Eric here.
What affects ocean salinity, and why should we care? The saltiness of the ocean is controlled by the water cycle. And the temperature and salinity of ocean water together control ocean density - the crucial driver of ocean circulation. Dr. Schmitt explains how ocean circulation works and its profound impacts on the climate.
Salinity's Connection to Climate Change and an Accelerated Water Cycle
Presented by Dr. Raymond Schmitt - March 5, 2013
SPURS Chief Scientist Dr. Raymond Schmitt is a Senior Scientist at Woods Hole Oceanographic Institution. Dr. Schmitt earned his Ph.D. in physical oceanography from the University of Rhode Island and his B.S. in physics from Carnegie Mellon University. His research interests include oceanic mixing processes such as "salt fingers" and the oceanic freshwater cycle. He has been a J.S. Guggenheim fellow and is a Fellow of the American Geophysical Union. Read more about Ray here.
What have we learned about the SPURS site and what's next? The interdisciplinary cruise undertaken by SPURS scientists involved the coordination of an armada of technology - from in-water instruments to shipboard measurements to satellites in orbit around Earth. Dr. Bingham shows us the results of the team's research, including real data collected during the cruise.
Follow that Salt! SPURS Results and the Future of Salinity Exploration
Presented by Dr. Fred Bingham - March 12, 2013
Dr. Fred Bingham is a Professor in the Department of Physics and Physical Oceanography at the University of North Carolina at Wilmington. His research interests include global distributions of sea surface salinity and large scale regional physical oceanography - the Kuroshio, the western North and Equatorial Pacific, and Onslow Bay, North Carolina.
