6. A major ecosystem shift in coastal east African waters during the 1997/98 Super El Niño as detected using remote sensing data

Abstract

Under the impact of natural and anthropogenic climate variability, upwelling systems are known to change their properties leading to associated regime shifts in marine ecosystems. These often impact commercial fisheries and societies dependent on them. In a region where in situ hydrographic and biological marine data are scarce, this study uses a combination of remote sensing and ocean modelling to show how a stable seasonal upwelling off the Kenyan coast shifted into the territorial waters of neighboring Tanzania under the influence of the unique 1997/98 El Niño and positive Indian Ocean Dipole event. The formation of an anticyclonic gyre adjacent to the Kenyan/Tanzanian coast led to a reorganization of the surface currents and caused the southward migration of the Somali-Zanzibar confluence zone and is attributed to anomalous wind stress curl over the central Indian Ocean. This caused the lowest observed chlorophyll-a over the North Kenya banks (Kenya), while it reached its historical maximum off Dar Es Salaam (Tanzanian waters). We demonstrate that this situation is specific to the 1997/98 El Niño when compared with other the super El-Niño events of 1972,73, 1982-83 and 2015-16. Despite the lack of available fishery data in the region, the local ecosystem changes that the shift of this upwelling may have caused are discussed based on the literature. The likely negative impacts on local fish stocks in Kenya, affecting fishers' livelihoods and food security, and the temporary increase in pelagic fishery species' productivity in Tanzania are highlighted. Finally, we discuss how satellite observations may assist fisheries management bodies to anticipate low productivity periods, and mitigate their potentially negative economic impacts. © 2020 by the authors.

Abstract

Coral reefs are exceptionally biodiverse and human dependence on their ecosystem services is high. Reefs experience significant direct and indirect anthropogenic pressures, and provide a sensitive indicator of coastal ocean health, climate change, and ocean acidification, with associated implications for society. Monitoring coral reef status and trends is essential to better inform science, management and policy, but the projected collapse of reef systems within a few decades makes the provision of accurate and actionable monitoring data urgent. The Global Coral Reef Monitoring Network has been the foundation for global reporting on coral reefs for two decades, and is entering into a new phase with improved operational and data standards incorporating the Essential Ocean Variables (EOVs) (www.goosocean.org/eov) and Framework for Ocean Observing developed by the Global Ocean Observing System. Three EOVs provide a robust description of reef health: hard coral cover and composition, macro-algal canopy cover, and fish diversity and abundance. A data quality model based on comprehensive metadata has been designed to facilitate maximum global coverage of coral reef data, and tangible steps to track capacity building. Improved monitoring of events such as mass bleaching and disease outbreaks, citizen science, and socio-economic monitoring have the potential to greatly improve the relevance of monitoring to managers and stakeholders, and to address the complex and multi- dimensional interactions between reefs and people. A new generation of autonomous vehicles (underwater, surface, and aerial) and satellites are set to revolutionize and vastly expand our understanding of coral reefs. Promising approaches include Structure from Motion image processing, and acoustic techniques. Across all systems, curation of data in linked and open online databases, with an open data culture to maximize benefits from data integration, and empowering users to take action, are priorities.

18. The Importance of Selected Individual Characteristics in Determining Market Prices for Fishers and Traders in Keny an Small-Scale Fisheries

Abstract

This article examines how selected socioeconomic characteristics of fishers and traders shape market prices at five coastal communities in Kenya. Focus groups elicited perceived factors affecting market prices, which were then tested using quantitative analysis. Ownership of fishing gear by fishers negatively influenced the prices taken. Fish traders who bought larger quantities paid a higher price. There was no significant relation between the choice of fish market by traders and fish price due to the diffused nature of the fish market. Although fish traders had relatively high income than fishers, the link between individual characteristics, market prices, and the outcomes of such interactions is more complicated than commonly perceived. The complexity is enhanced by the heterogeneity in different fisheries and of the prices at different markets and underlines the importance of continued documentation and exploration of the relationships between social and economic status and market prices for fishers and traders.

Abstract

Molecular beam source employing a shock tube is an attractive choice for the translational energy of around 1 eV, which corresponds to the typical activation energy of surface reactions. We developed a non-diaphragm type small shock tube as the molecular beam source generating high energy and dissociated molecular beams. The drastic reduction of the tube volume enables the repetitive operation of the shock tube at the frequency of 0.5 Hz. Installing the shock tube into the molecular beam setup, we measured the time-of-flight distributions of nitrogen and oxygen beams, and demonstrated the performance on controllability of the beam energy and the dissociation rate of molecules.
