TL;DR: Findings indicate that iron limitation can control rates of phytoplankton productivity and biomass in the ocean.
Journal ArticleDOI
The use of in situ and airborne fluorescence measurements to determine UV absorption coefficients and DOC concentrations in surface waters
Anthony Vodacek,Frank E. Hogel,Robert N. Swift,James K. Yungel,Edward T. Peltzer,Neil V. Blough +5 more
TL;DR: In this article, the authors compared the fluorescence (λ eX = 355 nm, λ em = 450 nm) of chromophore-containing dissolved organic matter (CDOM) determined in the laboratory to that determined with a shipboard fluorometer and an airborne laser fluorosensor off the US mid-Atlantic coast.
Journal ArticleDOI
Elevation changes of ice caps in the Canadian Arctic Archipelago
Waleed Abdalati,William B. Krabill,E. Frederick,S. Manizade,C. Martin,John Sonntag,R. N. Swift,Robert H. Thomas,James K. Yungel,Roy M. Koerner +9 more
TL;DR: In this article, the authors conducted repeat airborne laser surveys over the major ice caps in the Canadian Arctic Archipelago in the spring of 1995 and 2000 to measure elevation changes in the region.
Journal ArticleDOI
Inherent optical properties of the ocean: retrieval of the absorption coefficient of chromophoric dissolved organic matter from airborne laser spectral fluorescence measurements.
TL;DR: AirborneCDOM absorption measurements will find immediate application to forward and inverse modeling of oceanic water-leaving radiance and validation of satellite-retrieved products such as CDOM absorption.
Journal ArticleDOI
Validation of Terra-MODIS phytoplankton chlorophyll fluorescence line height. I. Initial airborne lidar results
Frank E. Hoge,Paul E. Lyon,R. N. Swift,James K. Yungel,Mark R. Abbott,Ricardo M. Letelier,Wayne E. Esaias +6 more
TL;DR: The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra spacecraft contains spectral bands that allow retrieval of solar-induced phytoplankton chlorophyll fluorescence emission radiance that strongly suggest that the FLH methodology is equally valid within similar oceanic provinces of global oceans.
