Modeling Arctic melt ponds using a resolved ice model with GCM forcing

Creator:: Collins, Lee E.
Abstract:: The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

Dynamic range and sensitivity requirements of satellite ocean color sensors: learning from the past

Creator:: Hu, Chuanmin, Feng, Lian, Lee, Zhongping, Davis, Curtiss O., Mannino, Antonio, McClain, Charles R., and Franz, Bryan A.
Abstract:: Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...

Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

Creator:: Epifanio, Jenna A.
Abstract:: The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

Wind-current Interactions of the Sri Lanka Dome and Tropical Indian Ocean

Creator:: Cullen, Kerstin
Abstract:: The southwest monsoon, which may be idealized as the northward movement of the intertropical convergence zone in the Indian Ocean associated with differential heating of land and ocean, brings a seasonal reversal of currents and winds in the Bay of Bengal and the Arabian Sea. Atmospheric convection from monsoon activity...

New Foraminifera-Based Proxies to Trace Changes to the Organic and Inorganic Carbon System Since the Last Glacial Maximum

Creator:: Fritz-Endres, Theresa
Abstract:: The production of carbon and export to deep ocean sediments is linked to carbon partitioning between the ocean and atmosphere and is a key driver of climate change over the glacial-interglacial transition. Yet conflicting reconstructions create barriers to understanding changes to the carbon system over this important climate transition. Production...

Comparison of larval development in domesticated and naturalized stocks of the Pacific oyster Crassostrea gigas exposed to high pCO₂ conditions

Creator:: Durland, Evan, Waldbusser, George, and Langdon, Chris
Abstract:: Ocean acidification (OA) has had significant negative effects on oyster populations on the west coast of North America over the past decade. Many studies have focused on the physiological challenges experienced by young oyster larvae in high pCO₂/low pH seawater with reduced aragonite saturation state (Ωarag), which is characteristic of...

The Role of Iron: How Natural and Human-Induced Iron Fertilization Could Change Ocean Productivity

Creator:: Adroli, Nurmalia
Abstract:: Iron (Fe) is an important limiting nutrient that can affect the rate of ocean primary production because it is required by phytoplankton as an enzymatic cofactor in photosynthesis, nitrogen fixation, and other essential metabolic functions. Most Fe reaches the surface of the open ocean via atmospheric dust deposition, which is...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...
