The biomass yields and management challenges for the Yellow sea large Marine Ecosystem
Environmental Development, 2016Co-Authors: Qisheng Tang, Yiping YingAbstract:Abstract This paper summarizes the changing biomass yields in the Yellow Sea large Marine Ecosystem (YSLME) in recent years and discusses the causes of such changes, including overfishing and climate changes. Meanwhile, two kinds of adaptive management strategies are recommended to support the biomass yields in YSLME, including resource-conservation-based capture fisheries (e.g. closed season/areas, stock enhancement etc.) and environmentally friendly aquaculture (e.g. integrated multi-trophic aquaculture, IMTA).

Sustainable development of the Yellow Sea Large Marine Ecosystem
Deep Sea Research Part II: Topical Studies in Oceanography, 2019Co-Authors: Zhaohui Zhang, Shouqiang WangAbstract:Abstract Large Marine Ecosystems (LMEs) are relatively large areas of ocean space, adjacent to the continents in coastal waters where primary productivity is generally high. Their natural characteristics allow for the application of governance practices based on the Ecosystem approach. The Yellow Sea Large Marine Ecosystem is a shallow semi-enclosed sea, located between the Chinese continent and Korean Peninsula. Three nations, the People's Republic of China (PRC), the Republic of Korea (ROK) and the Democratic People's Republic of Korea (DPRK), are located along the coast of Yellow Sea. Anthropogenic activity and global environmental changes are causing stress on the resources of the Yellow Sea Large Marine Ecosystem (YSLME). To address the transboundary challenges these impose, the Ecosystem-based Governance approach is being applied as the best method to sustain the goods and services of YSLME, which needs strong collaboration by all the YSLME nations. This paper summarizes the current status and threats of YSLME, as well as the present cooperative management systems being developed in the PRC and the ROK. Progress in implementing a collaboration mechanism, activities, and projects are also reviewed in the paper. The Yellow Sea Commission, a new intergovernmental collaborative organization, is expected to be established by YSLME nations (including the DPRK) to support Ecosystem-based Governance. The paper emphasizes the objectives and activities of a collaborative YSLME project for provisioning services, regulating services, cultural services, and supporting services of the YSLME under a new intergovernmental collaboration mechanism (YSLME Commission), which will push forward Ecosystem-based Governance and sustainable development of the YSLME as described in SDG 14, the United Nations 2015 Sustainable Development Goal and targets for the oceans.

maredat towards a world atlas of Marine Ecosystem data
Earth System Science Data, 2013Co-Authors: Erik Buitenhuis, Scott C Doney, M. Vogt, R. Moriarty, N. Bednarsek, K. Leblanc, Le C Quere, Yawei Luo, Colleen J Obrien, Todd D ObrienAbstract:Abstract. We present a summary of biomass data for 11 plankton functional types (PFTs) plus phytoplankton pigment data, compiled as part of the Marine Ecosystem biomass DATa (MAREDAT) initiative. The goal of the MAREDAT initiative is to provide, in due course, global gridded data products with coverage of all planktic components of the global ocean Ecosystem. This special issue is the first step towards achieving this. The PFTs presented here include picophytoplankton, diazotrophs, coccolithophores, Phaeocystis, diatoms, picoheterotrophs, microzooplankton, foraminifers, mesozooplankton, pteropods and macrozooplankton. All variables have been gridded onto a World Ocean Atlas (WOA) grid (1° × 1° × 33 vertical levels × monthly climatologies). The results show that abundance is much better constrained than their carbon content/elemental composition, and coastal seas and other high productivity regions have much better coverage than the much larger volumes where biomass is relatively low. The data show that (1) the global total heterotrophic biomass (2.0–4.6 Pg C) is at least as high as the total autotrophic biomass (0.5–2.4 Pg C excluding nanophytoplankton and autotrophic dinoflagellates); (2) the biomass of zooplankton calcifiers (0.03–0.67 Pg C) is substantially higher than that of coccolithophores (0.001–0.03 Pg C); (3) patchiness of biomass distribution increases with organism size; and (4) although zooplankton biomass measurements below 200 m are rare, the limited measurements available suggest that Bacteria and Archaea are not the only important heterotrophs in the deep sea. More data will be needed to characterise ocean Ecosystem functioning and associated biogeochemistry in the Southern Hemisphere and below 200 m. Future efforts to understand Marine Ecosystem composition and functioning will be helped both by further archiving of historical data and future sampling at new locations.

an intermediate complexity Marine Ecosystem model for the global domain
Deep-sea Research Part Ii-topical Studies in Oceanography, 2001Co-Authors: Keith J Moore, Joanie Kleypas, Scott C Doney, David M. Glover, Inez Y FungAbstract:A new Marine Ecosystem model designed for the global domain is presented, and model output is compared with field data from nine different locations. Field data were collected as part of the international Joint Global Ocean Flux Study (JGOFS) program, and from historical time series stations. The field data include a wide variety of Marine Ecosystem types, including nitrogen- and iron-limited systems, and different physical environments from high latitudes to the mid-ocean gyres. Model output is generally in good agreement with field data from these diverse Ecosystems. These results imply that the Ecosystem model presented here can be reliably applied over the global domain. The model includes multiple potentially limiting nutrients that regulate phytoplankton growth rates. There are three phytoplankton classes, diatoms, diazotrophs, and a generic small phytoplankton class. Growth rates can be limited by available nitrogen, phosphorus, iron, and/or light levels. The diatoms can also be limited by silicon. The diazotrophs are capable of nitrogen fixation of N2 gas and cannot be nitrogen-limited. Calcification by phytoplankton is parameterized as a variable fraction of primary production by the small phytoplankton group. There is one zooplankton class that grazes the three phytoplankton groups and a large detrital pool. The large detrital pool sinks out of the mixed layer, while a smaller detrital pool, representing dissolved organic matter and very small particulates, does not sink. Remineralization of the detrital pools is parameterized with a temperature-dependent function. We explicitly model the dissolved iron cycle in Marine surface waters including inputs of iron from subsurface sources and from atmospheric dust deposition. © 2001 Elsevier Science Ltd.
