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...

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

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...

Creator:: Vance, Jesse M.
Abstract:: The rapid increase in atmospheric carbon dioxide (CO₂) over the last 250 years has led to the absorption of approximately 550 billion tons of anthropogenic CO₂ by the global ocean. This oceanic uptake of CO₂ has resulted in decreasing pH and alterations to carbonate chemistry, threatening many ecologically and economically...

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...

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...

Creator:: Kish, Stacy W.
Abstract:: The increase in modern atmospheric CO₂ concentration (360 ppm) from pre-industrial levels (280 ppm) raises concern over the impact of anthropogenic carbon dioxide input on atmospheric chemistry. For this reason, it is important to understand the natural fluctuations of atmospheric carbon dioxide in the past. The Vostok ice core record...
