Dynamics of the Indian-Ocean oxygen minimum zones http://www.sciencedirect.com/science/article/pii/S007966111300027X ps. We nicknamed it (Indian Ocean) OMZ Bible. Why? Just take a look at Table 1.

means you keep on finding new things. It took us more than one year to refine the best numerical solution for our first paper, which was finally submitted last month. As I started to write the second paper, I needed to adjust the "best solution." That's when I discovered an even better solution than the one in the submitted manuscript... What would you do in this case? Leave the first paper as is, and go on to write a short paper to show how one can get a better solution, or revise the first paper using the latest best solution? For paper count, the answer is obvious. However, I don't think that will be our choice. (None of us, the first three authors, care much about publishing for the sake of publishing.) I truly enjoyed this new discovery, which seems to present itself. However, I know it's the experience that helps me to see more clearly now than ever... The good thing is my experience has been recognized by some colleagues as well. I will be visiting NOAA/PMEL, NASA/JPL, and UCLA in late September and early October to share these new results. Will you be here, Godot?
I was quite worried about how many people may come to my talk, which started at 9:30 am on Monday. By the time I counted five, my heart returned to its "normal position": good enough for me. To my surprise, many people came, more than I ever had when I gave seminars at the Second Institute of Oceano. Apparently, ecosystem modeling, or OMZ (oxygen minimum zone), is much more attractive than PO (physical oceano.). I made a great effort to speak Chinese, and asked the audience to help me out when I didn't know how to translate some terminology.
Joint Oceanography-IPRC Seminar Zuojun Yu Associate Researcher International Pacific Research Center University of Hawaii "Oxygen Minimum Zones in the Northern Indian Ocean" Abstract: In the tropics, mid-depth oxygen minimum zones (OMZs) are located in poorly ventilated regions below the thermocline. As a result, surface production can contribute to the strength of OMZs remotely as well as locally. In the northern Indian Ocean, OMZs can be found in the Arabian Sea (ASOMZ) and the Bay of Bengal (BBOMZ), consistent with the distribution pattern of ventilation ages. The intensity of the BBOMZ is moderate, while permanent suboxic condition (O2 ~5 μM) is reached in the Arabian Sea, clearly due in part to local production. The ASOMZ is the second most intense OMZ in the tropical ocean, with near-total depletion of oxygen at depths from 200-1000 m. The lower part of the ASOMZ (below 400 m) indicates a northward intensification, in agreement with the ventilation age revealed by CFC ratio. The upper part of the ASOMZ (above 400 m), however, appears east of the most productive regions along the western boundary, and there is no consensus about what causes this “eastward shift.” In contrast, much less is known about the distribution of BBOMZ. In both sub-basins, the relative roles of physical versus biological processes in generating OMZs have not been fully determined, in part because ocean models often fail to reproduce these OMZs. In this seminar, the speaker will present the latest results of their findings. Thursday January 20, 2011 3:00 p.m. MSB 100 http://www.soest.hawaii.edu/oceanography/seminar.html
