Linear trends over 15-year segments are computed for ... http://scripts.mit.edu/~sacklunch/paoc/?p=204 October 14 Marko Scholze University of Bristol A Global Carbon Cycle Data Assimilation System (CCDAS) to Infer Terrestrial CO2 Fluxes and Their Uncertainties Add to my calendar: ICS file or Google Atmospheric inversion studies have become an important tool for identifying terrestrial sources and sinks of CO2 at the interannual time scale. Such traditional top-down ... http://scripts.mit.edu/~sacklunch/paoc/?p=201 October 7 Wallace S. Broecker Columbia University A Failed Search for a 14C-Depleted Glacial-Age Isolated Abyssal Reservoir Add to my calendar: ICS file or Google Fundamental to the field of radiocarbon dating is not only the establishment of the temporal record of the calendar age-radiocarbon age offsets but also the development of an understanding of ... http://scripts.mit.edu/~sacklunch/paoc/?p=200 September 30 Glenn R. Flierl MIT Adaptive dynamics and effect of circulation and mixing Add to my calendar: ICS file or Google As climate and therefore the ocean changes, the organisms will also evolve to survive. Most large-scale biogeochemistry models work with a small set of plants and animals all having fixed traits; thus ... http://scripts.mit.edu/~sacklunch/paoc/?p=195 September 23 Christoph Stegert MIT/WHOI Congener Copepods in the northern Atlantic Ocean: an inter-regional analysis on the response to changes in environmental conditions Picture Add to my calendar: ICS file or Google As the investigation of key copepod species gained a special interest within GLOBEC several population models have been used within different regional projects. Copepods ... http://scripts.mit.edu/~sacklunch/paoc/?p=194 September 16 Jessica Benthuysen MIT/WHOI Nonlinear stratified spindown over a sloping bottom Picture Add to my calendar: ICS file or Google On a stratified sloping bottom, the nonlinear spindown of an along-isobath flow gives rise to asymmetry in Ekman pumping and suction. We show that nonlinear advection of buoyancy weakens Ekman pumping to a greater extent ... http://scripts.mit.edu/~sacklunch/paoc/?p=191 September 16 Jessica Benthuysen MIT/WHOI Nonlinear Stratified Spindown Over A Sloping Bottom September 23 Christoph Stegert MIT/WHOI Congener Copepods in the northern Atlantic Ocean: an inter-regional analysis on the response to changes in environmental conditions September 30 Glenn R. Flierl MIT Adaptive Dynamics and Effect of Circulation and Mixing October 7 Wally Broecker Columbia University A Failed Search for a 14C-Depleted Glacial-Age Isolated Abyssal Reservoir October ... http://scripts.mit.edu/~sacklunch/paoc/?p=190 June 3 Andrew Thompson DAMTP - University of Cambridge Vacillating jets:  baroclinic turbulence and topography Add to my calendar: Observations from satellite altimetry and output from high-resolution ocean models indicate that the Southern Ocean is characterized by an intricate web of narrow, meandering, filamentary jets.  These jets undergo spontaneous formation, merger and splitting events, ... http://scripts.mit.edu/~sacklunch/paoc/?p=188 May 27 Kjetil Våge MIT/WHOI Joint Program Surprising return of deep convection to the subpolar North Atlantic Ocean in winter 2007-2008 Add to my calendar: Deep open-ocean convection in the subpolar North Atlantic Ocean, which impacts the meridional overturning circulation and oceanic heat flux, has been largely absent since the mid-1990s. In the winter of ... http://scripts.mit.edu/~sacklunch/paoc/?p=187
