The effects of thermodynamic parameterizations, ice shelf geometry, and tides on modeled basal melting of Weddell Sea ice shelves

Creator:: Mueller, Rachael D.
Abstract:: Antarctic Ice Sheet mass balance and, hence, sea level change is affected by the floating extensions of outlet glaciers and ice streams that take up about 44% of the coastline (Drewry et al., 1982) and are referred to as "ice shelves". Ice sheet mass loss accelerates when these ice shelves...

Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

Creator:: O'Neill, Larry W.
Abstract:: Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

Turbulence in sheared, salt-fingering favorable environment

Creator:: Kimura, Satoshi
Abstract:: Instability and turbulence in sheared, salt-fingering favorable stratification are studied using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable stratification is gravitationally stable, because the unstable vertical gradient of salinity is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering instability can occur at the interface of these different water-masses....

Modern and past climate variability in the eastern Pacific warm pool

Creator:: Benway, Heather M.
Abstract:: Westward transport of water vapor across the Panama Isthmus helps to maintain the salinity contrast between the Atlantic and Pacific Oceans, important in thermohaline circulation and global climate. Relatively low sea-surface salinities and a strong, shallow pycnocline in the eastern Pacific warm pool (EPWP) region near Central America reflect high...

Nitrogen isotopes in a global ocean biogeochemical model : constraints on the coupling between denitrification and nitrogen fixation

Creator:: Somes, Christopher J.
Abstract:: We present a new nitrogen isotope model incorporated into the three-dimensional ocean component of a global Earth System Climate Model designed for millennial timescale simulations. The model includes prognostic tracers for the stable nitrogen isotopes, ¹⁴N and ¹⁵N, in the nitrate (NO₃ˉ), phytoplankton, zooplankton, and detritus variables of the marine...

The structure of an arctic shallow water benthic community : effects of ice gouging

Creator:: Braun, Gary Michael
Abstract:: The shallow water benthic habitat of the SW Beaufort Sea is frequently gouged by the keels of ice pressure ridges. This natural physical disturbance was hypothesized to be an important factor affecting the structure of the benthic community. Smith-McIntyre grab samples were taken from three discrete gouge axes and from...

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...

Elimination of sulfide interference with the colorimetric determination of nitrite

Creator:: Acuna, Jenaro A.
Abstract:: The interference of sulfide with the colorimetric determination of nitrite, by the method of Bendschneider and Robinson (1952), can be eliminated by passing the samples through a cationic exchange resin, Dowex 50W-X8, in the zinc form. This resin retains sulfide without affecting nitrite and the technique can be applied to...
