Physical-biological interactions in the Southern Ocean

Creator:: Moore, Jefferson Keith
Abstract:: Physical-biological interactions in the Southern Ocean were investigated using remote sensing data from several different satellite sensors. Satellite sea surface temperature data were used to study the dynamics of the Antarctic Polar Front (PF). Satellite ocean color data were used to estimate surface chlorophyll concentrations and their relation to various...

Observing biogeochemical cycles at global scales with profiling floats and gliders: Prospects for a global array

Creator:: Johnson, Kenneth S., Berelson, William M., Boss, Emmanuel S., Chase, Zanna, Claustre, Herve, Emerson, Steven R., Gruber, Nicolas, Kortzinger, Arne, Perry, Mary Jane, and Riser, Stephen C.
Abstract:: Chemical and biological sensor technologies have advanced rapidly in the past five years. Sensors that require low power and operate for multiple years are now available for oxygen, nitrate, and a variety of bio-optional properties that serve as proxies for important components of the carbon cycle (e.g., particulate organic carbon)....

High-frequency measurement of partial pressure and total concentration of carbon dioxide in seawater using microporous hydrophobic membrane contractors

Creator:: Hales, Burke, Chipman, David, and Takahashi, Taro
Abstract:: To investigate CO₂ chemistry in ocean water with greater time-space resolutions, we systems, which have state-of-the-art precision but an order of magnitude or better analysis, for carbon dioxide partial pressures (Pco₂) and total carbon dioxide Pco₂ system was based on equilibration of a CO₂-free carrier gas stream with seawater sample...

Sea-air CO₂ flux variability on the northeast Pacific continental margin

Creator:: Evans, Wiley
Abstract:: Carbon dioxide (CO₂) fluxes between the ocean and atmosphere on continental margins are difficult to diagnose because these regions experience large variability over spatial and temporal scales spanning meters to basins and hours to years, respectively. In a global sense, continental margins could represent a significant atmospheric CO₂ sink, equivalent...

Calcium carbonate production response to future ocean warming and acidification

Creator:: Pinsonneault, A. J., Matthews, H. D., Galbraith, E. D., and Schmittner, A.
Abstract:: Anthropogenic carbon dioxide (CO₂) emissions are acidifying the ocean, affecting calcification rates in pelagic organisms, and thereby modifying the oceanic carbon and alkalinity cycles. However, the responses of pelagic calcifying organisms to acidification vary widely between species, contributing uncertainty to predictions of atmospheric CO₂ and the resulting climate change. At...

High-frequency measurements of total CO₂ : Method development and first oceanographic observations

Creator:: Bandstra, Leah M.
Abstract:: As concern grows about the long-term effects of increasing atmospheric CO₂ concentrations, it becomes increasingly important to understand the cycling of carbon on Earth, particularly in the dynamic marine reservoir. Gas exchange and relatively rapid ocean mixing times mean that the oceans play a significant role in determining the atmospheric...

What is the skill of ocean tracers in reducing uncertainties about ocean diapycnal mixing and projections of the Atlantic Meridional Overturning Circulation?

Creator:: Schmittner, Andreas, Tonkonojenkov, Roman, Urban, Nathan M., Goes, Marlos, Haran, Murali, and Keller, Klaus
Abstract:: Current projections of the oceanic response to anthropogenic climate forcings are uncertain. Two key sources of these uncertainties are (1) structural errors in current Earth system models and (2) imperfect knowledge of model parameters. Ocean tracer observations have the potential to reduce these uncertainties. Previous studies typically consider each tracer...

Paleoclimate, paleoventilation, and paleomagnetism as recorded in a 17kyr marine sediment record from the SE Alaska margin

Creator:: Davies, Maureen Helen
Abstract:: The deglacial behavior of the sub-Arctic North Pacific is poorly constrained, with many published records suffering from limited age control due to extensive post- depositional biogenic carbonate dissolution. Potential alternative dating methods could include the correlation of stable-isotopic and/or paleomagnetic secular variation records to an independently-dated regional template, however no...

Impact of tropical instability waves on nutrient and chlorophyll distributions in the equatorial Pacific

Creator:: Evans, William Wiley
Abstract:: Tropical instability waves (TIWs) are prominent seasonal features in both the equatorial Pacific and Atlantic Oceans. This work quantifies their role in modulating the distributions of nutrients and phytoplankton biomass. Using an eight year record of biannual ship observations along the Tropical Atmosphere Ocean (TAO) buoy array, cruise sections crossing...
