Dr. Carol Janzen has a Ph.D. in physical ocean-
ography and has over three decades of experi-
ence conducting and managing interdisciplin-
ary observational research in estuarine, coastal
shelf and offshore environments. As senior
oceanographer at Sea-Bird Electronics, she
spent much of her tenure conducting instru-
ment characterization assessments and perfor-
mance testing in the lab and in the feld. She
also evaluated data processing and sampling
implementation protocols, and developed and
analyzed calibration, laboratory and in-feld
validation methodologies. Janzen recently
became director of operations at the Alaska
Ocean Observing System based out of Anchorage, Alaska.
Dr. Norge Larson, chief science executive, is a former owner and president of
Sea-Bird Electronics, and a former president of Sea-Bird Scientifc. In his cur-
rent role, Larson oversees the scientifc work at Sea-Bird Scientifc, and helps
outside scientists and government agencies with their questions. He has a B.S.
in physics from Augsburg College and a Ph.D. in ocean physics from the Uni-
versity of Washington.
David Murphy is the director of science for the Ocean Research Business Unit
at Sea-Bird Scientifc, with specifc responsibilities in oceanographic sensor de-
sign, characterization and calibration. He has an M.S. in electrical engineering
and a degree in chemical oceanography. In his 24 years with Sea-Bird, his re-
sponsibilities have included providing science input for product development,
SBE's metrology work, oversight of SBE's calibration facilities, consultation with
Sea-Bird's key customers, presentations at scientifc conferences, and customer
training.

Beed and Kristi Anson, who conducted the freeze/thaw
experiments and post-calibrations of returned Argo foats.
Their ongoing hard work and dedication to the Argo CTD
calibration protocols have helped make the Argo program
