The central hypothesis of this project is that natural iron-complexing organic ligands in seawater differentially regulate iron availability to large (microplankton) and small (nano and picoplankton) class of phytoplankton and thereby strongly influence the potential carbon sequestration in High Nitrate Low Chlorophyll (HNLC) regions of the ocean. The primary project goals are to: 1) determine how different natural and synthetic Fe chelators affect Fe availability to phytoplankton species that are representative of offshore HNLC waters, 2) elucidate how the changes in absolute concentrations of these chelators affect the longer-term ecosystem response to alleviation of Fe limitation, and 3) ascertain how changes in the ligand composition affect rates of cell sinking and aggregation - representative measures of the efficiency of carbon sequestration to the deep.

Using atomistic simulations of dislocation motion in Ni and Ni-Au alloys we report a detailed study of the mobility function as a function of stress, temperature and alloy composition. We analyze the results in terms of analytic models of phonon radiation and their selection rules for phonon excitation. We find a remarkable agreement between the location of the cusps in the {sigma}-v relation and the velocity of waves propagating in the direction of dislocation motion. We identify and characterize three regimes of dissipation whose boundaries are essentially determined by the direction of motion of the dislocation, rather than by its screw or edge character.
