Abstract:
The Tara Ocean expedition has collected data defining the upper ocean ecosystem, biogeochemistry, optical properties, and ocean color from Sep. 2009 to Mar. 2012. This data set comprises an extensive, comprehensive and unique opportunity to analyze optical data on a global scale and relate it to biogeochemical data, as well as ocean color. The Tara consortium has committed to make all the data collected freely and publicly available. Some of it, in particular the data collected using UMaine’s instrument, has been processed and posted on public data bases. In particular, hyper-spectral absorption and attenuation of particles have been collected along most of the Tara s track. Relating these to HPLC pigments, in water IOPs (backscattering at two wavelength, chlorophyll and CDOM fluorescence), hyper-spectral reflectances (from a radiometer buoy) and satellite ocean color will help quantify the advantages of hyperspectral remote sensing of ocean color in anticipation of missions such as the upcoming PACE, ACE and GEOCAPE, and help determine the visible wavelengths with most information regarding in-situ ecosystem composition.  We propose to participate in the upcoming Tara pan-Arctic cruise which will take place from May to November 2013, measuring and collecting samples similar to those on Tara Oceans. We will be responsible to the bio-optical data and enhance it with in-line CDOM, in-line backscattering, and a novel prototype laser fluorescence instrument (WETLabs ALFA) providing information on phytoplankton composition and physiology. Analysis and interpretation of the Tara bio-optical data will be the centerpiece of a PhD thesis, to be performed by a graduate student at UMaine who has recently taken the Ocean Optics class, under the guidance of Boss and collaborators from LOV. Collaborators from LOV (Bricaud, Claustre and Antoine), besides being prominent scientists in the field of bio-optics, have been responsible for key bio-optical and biogeochemical data collected on the Tara. They will assist and collaborate with the UMaine team in all aspects of the scientific analysis of the Tara data.
