The United Nations’ Sustainable Development Goals are an admirable set of targets set out to achieve a better world–but how do they interact with each other? Are some more pivotal to the success of all? Possibly.
The excitement around Sustainable Development Goals has faded somewhat since the United Nations meeting in 2015, and now comes the less inspiring dirty work of analysis and policy-setting to achieve them.

Due to their wide-ranging swimming behaviors, migratory fish, marine mammal, seabird and sea turtle species experience a variety, and an increasing amount, of anthropogenic pressures over the course of their lives. These threats, including climate change, overfishing, and marine pollution, combined with conservation strategies that largely fail to consider spatial connectivity over the life cycle, are resulting in declining populations worldwide.
The mesopelagic zone of the ocean, which includes the 200 to 1000 m below the ocean surface, is poorly understood. Our limited scope of understanding for these areas may become increasingly problematic, as they may be vulnerable to global issues such as climate warming, deoxygenation, acidification, commercial fishing, and seabed mining.
Due to the expansion of fishing practices, fish catches have become stagnant at best while global fishing efforts continue to grow, ultimately creating major stresses on marine resources. Fisheries impacts on both coastal and deep-sea ecosystems are well understood and documented; however, the biological and ecological impacts of fishing on open-ocean systems are not well studied or documented.
Madingley is a global computational model. To a broad approximation, the Madingley model represents all (most) forms of life.

Explaining Ocean Warming is a comprehensive report produced by the International Union for Conservation of Nature (IUCN) looking at the impacts of warming on ocean life, ecosystems, and goods and services. The report is the work of 80 scientists from 12 countries, launched during the IUCN World Conservation Congress, September 1-10 in Hawaii. Nereus Program research was contributed to two chapters within the report.
Biomass is the mass of organisms in an ecosystem or community; it is thought of in terms of energy for the next trophic level – the higher chain in the food web. For example, the biomass of plankton, which may be eaten by herring, which may be eaten by tuna.
This blog explores the collaborative process I followed as a Nippon Foundation-Nereus Program consulting artist. I was commissioned to create 17 illustrations celebrating the beauty and complexity of our planet’s oceans and fisheries.
Nereus Fellow at UBC Muhammed Oyinlola attended the ClimEco5 Summer School organized by the Integrated Marine Biogeochemistry and Ecosystem Research project (IMBER), titled ‘Towards more resilient oceans: Predicting and projecting future changes in the ocean and their impacts on human societies’. The summer school took place from August 10 to 17, in Natal, Brazil.
alps, 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.
The Nereus Program was created to look at ocean questions that need input from experts on a range of topics from around the world. This past May 30 to June 3, nearly 50 of these experts gathered at the University of British Columbia for the Nereus Program Annual General Meeting.
In our current eco-friendly world, where climate change makes front-page news and the killing of a lion launches thousands of Facebook posts, how can a porpoise be nearing extinction and most of the world not even know of its existence?

“Seasonal phytoplankton blooms in the North Atlantic linked to the overwintering strategies of copepods,” co-authored by Nereus Fellow Rebecca Asch (Princeton University), was recently published in Elementa: Science of the Anthropocene.
The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), released in 2013 and 2014, highlighted the vulnerability, impacts and adaptation of marine systems to climate change and ocean acidification.
Climate change is expected to have major impacts on the ocean, the species that live there, and the people who rely it for their food and livelihood. Since the beginning of the 20th century, CO2 emissions from human activities have altered physical and chemical properties of the ocean. The ocean has become warmer and, in some areas, less oxygenated, which has caused changes in the productivity and distribution of marine species.
For three days from January 18th to 20th, Monterey, California, has become an aggregation hotspot for more than 100 of the world’s foremost experts on the conservation and management of the three bluefin tuna species that inhabit our global ocean.

“I had a bird dog named Gus. When Gus couldn’t find pheasants he worked up an enthusiasm for Sora rails and meadowlarks. This whipped-up zeal for unsatisfactory substitutes masked his failure to find the real thing. It assuaged his inner frustration.” – Aldo Leopold (1949).
