“…This study and other recent studies (Dauhajre et al, 2017(Dauhajre et al, , 2019Xuan et al, 2019) suggest that SVA may change the interior and even to the bottom boundary layer structure on the continental shelf. Shelf seas with active submesoscale processes and high PP can be also found elsewhere, for example, in the North Sea (Sherman, 2019;Zhao, 2019;Zhao et al, 2019), South China Sea (Chen et al, 2019), and Iberian shelf (Zhang et al, 2016), and reflected in the heterogeneity of organic matter deposition on surface sediments (Zhang & Wirtz, 2017;Zhang, Wirtz, et al, 2019). The significance of SVA for the phytoplankton dynamics is therefore believed to be typical in stratified shelf sea environments.…”

“…When compared with that of other regions, the primary productivity (PP) of the ECS is at the 75th percentile of the 67 continental margin ecosystems compiled by Sherman (2019). The high PP of the ECS supports several well-known fishing grounds in the region (Gong et al, 2003;Sherman, 2019). of the eutrophic Changjiang Diluted Water within the inner shelf (Zeng et al, 2012).…”

Impact of Submesoscale Vertical Advection on Primary Productivity in the Southern East China Sea

et al. 2020

This study aims to investigate the impact of submesoscale vertical advection (SVA) on the primary productivity in the southern East China Sea. The analysis is based on a comparison between two numerical simulations by using a three‐dimensional coupled physical‐biogeochemical model. One simulation directly resolves SVA on a high‐resolution mesh, and the other leaves SVA unresolved on a low‐resolution mesh. The high‐resolution simulation outperforms the low‐resolution simulation in reproducing the observed chlorophyll distribution, particularly in summer. Resolving SVA results in an approximately 40% increase in primary productivity during the summer, though SVA activity is relatively weak in this season than in other seasons. Among multiscale physical processes, SVA, rather than mixing, is found to be the most important vertical nutrient supply pathway from the nutrient‐rich bottom water to the nutrient‐depleted surface water in summer, particularly on the middle and outer shelves. The impact of SVA on the shelf is unique compared to the open ocean in that it efficiently enhances vertical supply of nutrient‐rich subsurface waters to the nutrient‐depleted surface layer. This study highlights the importance of SVA in promoting primary productivity in stratified shelf seas.

The Red Sea Fisheries - Threats and Proposed Solutions

The global oceans and seas are broadly balkanized into 66 large Marine Ecosystems (LMEs), and the Red Sea is the number 33 of these LMEs. Moreover, they provide job opportunities for millions of people and generate about three-quarters of the world fish production annually. The Red Sea (LME#33) is believed to be the saltiest and warmest sea among these LMEs. The main aim of this paper is to suggest policy solutions as proper planning strategies for the Red Sea countries to restore the depleted naturally fish stocks and to sustain natural fisheries stocks to achieve socio-economic and environmental goals in the coming years. The methodology used in this research is a merge of descriptive and analytical approach. The analytical research focusses on the main causes and losses that led to depleting natural fisheries stocks in the Red Sea such as (overfishing, Illegal, Unreported, and Unregulated (IUU) fishing, coastal development, and climate change). This research analyses the data collected from the literature and the SWOT analysis outcomes to investigate the current status-quo and to propose alternative solutions for the natural fish stock depletion in the Red Sea. Keywords: The Red Sea, Fisheries, SDG 14.4, Socioeconomic, Overfishing, IUU fishing.

“…The Large Marine Ecosystem (LME) Approach for the assessment and management of coastal and ocean ecosystem services has gained momentum since the mid-1980s (Sherman, 2005). It combines the legal principles of the United Nations Convention on the Law of the Sea (UNCLOS) with a multi-sectoral and multidisciplinary strategy for assessing and managing the changing state of the world's sixty-six LMEs (Sherman, 2019). These highly productive areas of the ocean share six main priority threats (United Nations Development Programme, 2017) including:…”

Navigating the Complexity of Regional Ocean Governance Through the Large Marine Ecosystems Approach

Governance is a multifaceted and complex process, involving a wide range of stakeholders from numerous institutions and individuals with different interests, agendas and sets of skills. A number of barriers exist for states to work together on securing their shared coastal and marine ecosystems, with discussions often becoming clouded when disputes arise over Exclusive Economic Zones, borders, oil and gas resources, continental shelves, maritime transport, and fisheries. Over the last twenty-six years, the Global Environment Facility’s (GEF) International Waters focal area has utilized the Large Marine Ecosystem (LME) approach to navigate the complex problems related to transboundary issues affecting the world’s marine ecosystems, of which forty-one out of sixty-six are shared (62%) by one or more countries. To overcome the disputes and assumptions about the intentions of neighboring states, the GEF developed the Transboundary Diagnostic Analysis-Strategic Action Programme (TDA-SAP) assessment and strategic planning processes to help countries learn how to work together and build trust. This formal and inclusive process analyses all pertinent factual and scientific information to set priorities for action. This practical method for integrating science into management has provided an effective approach to inform and advance sustainable LME management and governance regimes; however, there is not a one size fits all approach. This review presents six examples from the GEF International Waters portfolio that demonstrate how the LME Approach and TDA-SAP process have helped countries find the best way to mainstream ecosystem-based management approaches into existing contexts and politics. While these examples span a wide range of different settings (geographic, political, socio-economic, temporal), they have all applied the LME Approach and TDA-SAP process to tackle complex regional ocean governance issues. Each example provides a historical perspective, the key results achieved, and their unique lessons learned/best practices. Furthermore, the review identifies some of the overall shortcomings of the process and the common lessons learned, underscoring the complex and daunting challenge of achieving effective governance for multi-country LMEs. The experience provided by these examples shows that practical ecosystem-based management of the ocean and its coasts not only requires flexibility and adaptability, but also time, associated long-term vision and commitment.
