November 2000

This year is an auspicious one for two members of the CGD Oceanography Section, both of whom have picked up major awards from scientific societies.

Associate scientist Keith Lindsay has received the Richard C. DiPrima Prize from the Society for Industrial and Applied Mathematics. Keith accepted the honor at the SIAM annual meeting, held in Puerto Rico in July. Created in honor of a former SIAM president, this award recognizes the outstanding doctoral dissertation submitted from the preceding two years. Keith wrote his dissertation, "A Three-Dimensional Cartesian Tree-Code and Applications to Vortex Sheet Roll-Up," in the mathematics department at the University of Michigan in 1997, shortly before he joined NCAR. "My adviser entered [the dissertation in the contest]. I didn't actually even know he'd entered it. The e-mail telling me I'd won was very much a surprise."

The goal of the project, says Keith, was "to numerically study theoretical aspects of vortex sheets, which are an idealization of shear flows. It wasn't related to atmospheric sciences." The SIAM committee called Keith's thesis a "beautiful solution to a long-standing problem."

Word of mouth helped steer Keith to his current job in CGD. "I'd heard good things about NCAR from other people I knew who worked here, and I saw a job posting that involved mathematical skills." He's now working on biogeochemical modeling of the ocean under the direction of Scott Doney.

Scott will be picking up an award of his own next month at the fall meeting of the American Geophysical Union. He is one of three recipients of the AGU's James B. Macelwane Medal for 2000. The medal recognizes "significant contributions to the geophysical sciences by an outstanding young scientist." Scott joins the company of past winners that include Tom Holzer (HAO), David Hanson (ACD), and Susan Solomon (NOAA).

Scott, now a Scientist III, came to NCAR as an ASP postdoc in 1991 after completing a Ph.D. in chemical oceanography in the Massachusetts Institute of Technology–Woods Hole Oceanographic Institution Joint Program.

Scott's colleague from WHOI, David Glover, submitted the nomination and is preparing the award citation. They've worked together since Scott's first days as a graduate student in Woods Hole. Glover says that Scott's interests and talents are many and varied and that his work has been both prolific and insightful on topics including

Recently Scott has been collaborating with Inez Fung (University of California, Berkeley) on a global coupled carbon-cycle model within the frame of NCAR's Community Climate System Model. The goal is to look at natural variability and anthropogenic climate responses and feedbacks over the next couple of hundred years. Another project is the development of a new model of the biochemistry of marine ecosystems, looking at the effects of iron fertilization and nitrogen fixation. He's also conducting analyses of ocean mesoscale biological variability from high-resolution models and satellite data.

"It's a great honor and rewarding to see my work being recognized," says Scott. "I realize, though, that no one works in a vacuum and that the award really reflects contributions of all of my colleagues."
