WELCOME TO OCB

OCB Mission

To establish the evolving role of the ocean in the global carbon cycle, in the face of environmental change, through studies of marine biogeochemical cycles and associated ecosystems

OCB Overarching Scientific Themes

Improve understanding and prediction of:
1) oceanic uptake and release of atmospheric CO2 and other greenhouse gases;
2) climate-sensitivities of biogeochemical cycles and interactions with ecosystem str

About OCB

   The Ocean Carbon and Biogeochemistry (OCB) program focuses on the ocean’s role as a component of the global Earth system, bringing together research in geochemistry, ocean physics, and ecology that inform on and advance our understanding of ocean biogeochemistry. The overall program goals are to promote, plan, and coordinate collaborative, multidisciplinary research opportunities within the U.S. research community and with international partners. I

     Again, the process of earning a living has gotten in the way of the process of having fun, and I haven't done much to the turbine for a couple of months or so. However, I recently spend a couple of evenings building a prototype of a liquid fuelled burner system for the engine, and also stripped, cleaned, painted, and rebuilt the turbine itself. I also replaced the oil pump, rebuilt the oil tank and feed system, built an integrated starting system for the engine

Plug and Slot Welds

Plug welds and slot welds are used join overlapping members, one of which has holes (round for plug welds, elongated for slot welds) in it. Weld metal is deposited in the holes and penetrates and fuses with the base metal of the two members to form the joint. (Note: for the sake of graphical clari

Groove Welds

The groove weld is commonly used to make edge-to-edge joints, although it is also often used in corner joints, T joints, and joints between curved and flat pieces. As suggested by the variety of groove weld symbols, there are many ways to make a groove weld, the differences depending primarily on the geometry of the parts to

Fillet Welds

The fillet weld (pronounced "FILL-it," not "fil-LAY") is used to make lap joints, corner joints, and T joints. As its symbol suggests, the fillet weld is roughly triangular in cross-section, although its shape is not always a right triangle or an isosceles triangle. Weld metal is deposited in a corner formed by the fit-up of the t

The acetylene (acetylene) is the simple the alkyne, also calls the acetylene. The molecular formula HC≡CH, chemical formula CH, the achromatic color has the fragrant smell inflammable gas. The acetylene molecular weight 26.4, the gaseous density 0.91 (Kg/m3), the calorific value 12800 (kilocalorie /m3) in the oxygen the rapidity of combustion 7
