A global biogeographic classification of the mesopelagic zone
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.
Majority of Pacific bluefin tuna migrate across the ocean
Pacific bluefin tuna are in trouble -- they're at just 2.6% of historic, pre-fishing levels. They have been overfished and this overfishing is still continuing. Due to this dire situation, proper management of the stocks is increasingly important, yet information of the fish's life history and migration patterns is limited.
A rapid assessment of co-benefits and trade-offs among Sustainable Development Goals
A new paper, ‘A rapid assessment of co-benefits and trade-offs among Sustainable Development Goals‘, has been published in Marine Policy and includes contributions from various Nereus affiliates. This study highlights how achieving SDG 14: Life Below Water targets contributes to the accomplishment of other SDGs

Step forward in protecting the high seas, despite competing interests
The high seas — also called international waters — comprise 64% of the world’s oceans and 45% of the earth’s surface. They are shared by the world but governed by no one country. That means that the incredible biodiversity of the high seas, from seaweeds to fish to sharks, is not currently protected.
Measuring mercury levels in the ocean: A scientist at sea on the Research Vessel Endeavor
By Colin Thackray, Nereus Fellow at Harvard University
The oceans are very expansive. Their enormous size and distance from where people stay long term presents a challenge for scientists monitoring the oceans. Unlike many atmospheric measurements for meteorology which we can make just outside of cities, often at airports, to get good measurements for ocean science, a journey on the sea is often required. Around the world, there are many ships designed or outfitted specifically for bringing scientists to the ocean – so called Research Vessels (RVs).
The UN Oceans Conference and Sustainable Development Goals: Are partnerships providing the way forward?
The global oceans provide hundreds of millions of people with livelihoods, food and nutritional security, and are crucial for employment, economic development, and export earnings in many countries and coastal communities around the world. The status of these important ecosystems and its fisheries resources are however rapidly declining, following decades of unsustainable exploitation patterns, overcapacity, and unsuccessful governance interventions.
