    Sources of uncertainties in 21st century projections of potential ocean ecosystem stressors

    The ocean has provided incredible services for us — taking up 28% of carbon emissions since preindustrial levels and absorbing 93% of the Earth’s excess heat since the 1970s — but because of this, it is undergoing changes. In order to manage ocean ecosystems and resources in the future, we must begin to understand what those changes may look like using climate change impact projections.

    Dispute Resolution and Scientific Whaling in the Antarctic

    Newly published in the Asia-Pacific Journal of Ocean Law and Policy is the paper “Dispute Resolution and Scientific Whaling in the Antarctic: The Story Continues” by Nereus Fellow Richard Caddell, Utrecht University. The paper looks at the implications of judgements by the International Court of Justice against Japanese scientific whaling in the Southern Ocean.

    Rethinking the Role of Salps in the Ocean

    Salps, a type of gelatinous zooplankton, are often confused with jellyfish and while jellyfish research has increased drastically, salps have been ignored. The authors write that there “has been no comprehensive study on the biology or ecological impact of salps in almost 20 years”. This paper looks at four misconceptions about salps, including that salps are jellyfish, salps are rare, salps are trophic dead ends, and salps have a minor role in biogeochemical cycles.

    Illustrating the ocean: The process of depicting the complexity of marine ecosystems

    By Jenn Paul Glaser, Nereus Program Consulting Artist

    Our goal was to produce painterly digital collages that were conceptual in nature but grounded in state-of-the-art research. The culminating body depicted a total of about 30 species within at least 16 diverse marine ecosystems.

    Instability in the South China Sea: Ecosystem challenges and political complexities

    One of the most significant – and increasingly bitter – international disputes of recent years has engaged legal claims over maritime territory in the South China Sea. Under the United Nations Convention on the Law of the Sea of 1982 (UNCLOS), to which the main protagonists are parties, states are entitled to claim an Exclusive Economic Zone (EEZ) conferring sovereign rights and jurisdiction up to 200 nautical miles of maritime space from their coasts. In the South China Sea, however, this position has been complicated by historical claims over a series of small islands and reefs within the southern section of this area.

    Five key aspects of sustainable aquaculture: Can aquaculture help tackle global food security, especially in Africa?

    by Muhammed Oyinlola, Nereus Fellow

    Aquaculture, the farming of aquatic species, is gradually becoming an important aspect of solving the challenge of global food security. The supply of seafood from fisheries is declining; fish stocks can only be increased if we reduce our fishing pressures, yet governments continue to subsidize the fishing industry for us to fish more. Hence, the open window we have is aquaculture. My argument is that we need to change from hunting in the ocean to farming the oceans just the way we changed hunting on land to producing animal protein by farming. Can aquaculture be our best option to increase the seafood supply for the world’s ever increasing population?
