Seasonal or chronic nutrient limitations in the photic zone limit large-scale cultivation of seaweed (macroalgae) in much of the world's oceans, hindering the development of macroalgae as a biofuel feedstock. One possible solution is to supply nutrients using a diel depth-cycling approach, physically moving the macroalgae between deep nutrient-rich water at night and shallow depths within the photic zone during the day.

This brief sets out the contribution that aquaculture can make to healthy diets and resilient food systems. It provides guidance for policymakers as they consider decisions related to the expansion of aquaculture, balancing issues related to diets and food security, economic growth and employment, and the environment.

Since the industrial revolution, the world’s oceans have become increasingly acidic. The main drivers of ocean acidification in Massachusetts are (1) global increases in atmospheric carbon dioxide resulting from anthropogenic emissions, and (2) local nutrient pollution leading to the eutrophication of coastal waters.

Trace elements (TEs) frequently contaminate coastal marine sediments with many included in priority chemical lists or control legislation. These, improved waste treatment and increased recycling have fostered the belief that TE pollution is declining. Nevertheless, there is a paucity of long-term robust datasets to support this confidence.

Economics is a discipline that shapes decisions of the utmost consequence, and so matters to us all. The Dasgupta Review at last puts biodiversity at its core and provides the compass that we urgently need. In doing so, it shows us how, by bringing economics and ecology together, we can help save the natural world at what may be the last minute – and in doing so, save ourselves.

As more companies and governments make commitments to address plastic pollution, several plastic offset claims and credit schemes have emerged.
We reviewed the current landscape of standards, certifications and credit programs to assess the strengths and weaknesses of current programs and whether they are equipped to help buyers meet their impact objectives.

Plastics are the most common form of marine debris. They originate with a variety of land and ocean-based sources across industries; enter the water in many ways; and negatively impact the ocean and Great Lakes. Once in the water, plastic debris never fully biodegrades.

The Global Commission on Adaptation's landmark report, Adapt Now: A Global Call for Leadership on Climate Resilience, puts forward a bold vision for how to transform key systems to be more resilient and productive. Report authors found that adaptation can produce significant economic returns — from 2:1 to 10:1 — as well as numerous social and environmental benefits.
The report, co-authored by WRI, laid the foundation for the Commission's Year of Action and many of the announcements made at the Climate Adaptation Summit.

Zongguo W. et al., Nature CommunicationsSince the late 1990s, the trend of plastic waste shipment from developed to developing countries has been increasing. In 2017, China announced an unprecedented ban on its import of most plastic waste, resulting in a sharp decline in global plastic waste trade flow and changes in the treatment structure of countries, whose impacts on global environmental sustainability are enormous but yet unexamined.

Anna Sanchez-Vidal et al., Scientific Reports, NatureThere is strong evidence that the seafloor constitutes a final sink for plastics from land sources. There is also evidence that part of the plastics lying on the shallow seafloor are washed up back to the shoreline. However, little is known on the natural trapping processes leading to such landwards return.
