Carbon and Nutrient Fluxes in Continental Margins: A Global by Kon-Kee Liu, Larry Atkinson, Renato Quiñones, Liana

By Kon-Kee Liu, Larry Atkinson, Renato Quiñones, Liana Talaue-McManus

This ebook is a made from the joint JGOFS (Joint worldwide Ocean Flux Study)/LOICZ (Land–Ocean Interactions within the Coastal quarter) Continental Margins activity group which was once confirmed to facilitate continental margins learn within the tasks. It includes signi cant info at the actual, biogeochemical, and ecosystems of continental margins nationally and domestically and gives a truly helpful synthesis of this knowledge and the actual, biogeochemical and surroundings strategies which take place on continental margins. The ebook of this booklet is well timed because it presents a truly powerful beginning for the improvement of the joint IMBER (Integrated Marine Biogeochemistry and Ecosystems Research)/LOICZ technological know-how Plan and Implemen- tion process for biogeochemical and ecosystems study within the continental margins and the affects of worldwide switch on those platforms. This initiative will movement ahead built-in biogeochemical and ecosystems study within the continental margins. We thank all of the participants to this quantity and particularly Kon-Kee Liu who has committed loads of time to making sure a great e-book is released.

Sample text

In shallower part of the continental shelf, 20–50% of primary production may be consumed on the seafloor (Rabouille et al. 2001). The small fraction of organic carbon that survives degradation and oxidation may be accumulated on the seafloor, where anoxic conditions may prevail. Without sufficient oxidants, the organic matter may undergo disproportiona- 1 Biogeochemistry of Continental Margins in a Global Context tion by splitting into compounds with higher and lower oxidation states during fermentation reactions brought about by anaerobic microbes.

The most important processes are briefly discussed below to illustrate how they may affect biogeochemical fluxes. 1 Physical Processes There are many physical processes that control circulation and mixing in continental margins (Blanton 1991; Huthnance 1995), which in turn control the transport and distribution of biogeochemical materials. The crucial ones are illustrated in Fig. 5. These processes occur in different timescales under the influences of tides, wind stress, buoyancy forces, and bottom friction (Blanton 1991).

These conditions often do not exist. Some of the complications in biogeochemical processes are to be discussed later. However, the mass balance was still set as the minimal requirement to achieve a legitimate biogeochemical budgeting. It has been previously hinted (Liu et al. 2000) that, for an integrated study of the global biogeochemical cycle of continental margins, the main approach should be dictated by modeling, which is an indispensable tool for a rigorous approach to Earth system science.
