The long spined sea urchin Diadema antillarum was an abundant grazer on Caribbean coral reefs, until 1983–1984, when densities were reduced by ∼98% during a region wide die-off. Since then, there has been very little natural recovery of the species and interest is growing in applying aquaculture as a …

Heeft Nederland met haar enorme potentie aan windparken op zee een verdienmodel Noordzee in handen, vraagt Martien Visser zich af. Nou, vergeet het maar, stelt hij. “Onder het huidige gesternte is het een stevig verliesmodel voor Nederland.”

The 1983-1984 die-off of the long-spined sea urchin Diadema antillarum stands out as a catastrophic marine event because of its detrimental effects on Caribbean coral reefs. Without the grazing activities of this key herbivore, turf and macroalgae became the dominant benthic group, inhibiting coral recruitment …

Greater New Orleans is surrounded by wetlands, the Mississippi River and two lakes. Excess rain can only be drained off with pumping systems or by evaporation due to the bowl-like shape of a large part of the city. As part of the solution to make New Orleans climate adaptive, green infrastructure has …

Seaweed-based solutions can offer a valuable contribution in addressing today’s challenges such as climate change, food availability and finding alternatives to fossil-based value chains. To achieve this, the European seaweed sector needs to scale-up, and devise smart solutions to make the production …

Diadema sea urchins (Diadema antillarum) are important algae grazers, but restoration attempts often record low survival of restocked individuals. This article sheds light on one of the causes for unsuccessful restocking. Restocked sea urchins were monitored with time-lapse cameras for 10 days. There …

This is not a catalogue of finished work. This is also not a report of our collaboration on climate imaginaries. Instead, this zine offers a peek into an ongoing collaboration between artists, designers and researchers who have jointly turned their attention to the rising ocean. In riso-printed* collages, …

This thesis is a literature review on the impact of global warming on the great whale pump in Europe. Global warming is known to have an effect on different ecosystems around the world. However, what is largely unknown is the impact of global warming on marine systems and specifically large whales that …

The massive die-off of the sea urchin Diadema antillarum in 1983–1984 is one the main reasons for low coral recruitment and little coral recovery in the Caribbean. As the natural recovery of D. antillarum is slow to non-existent, multiple restoration studies have been attempted. There are currently three …

From the very beginnings of the Kingdom of the Netherlands, water management has been a topic of prime importance. This subject has taken even greater priority in recent times due to climate change and the consequent erratic weather and sea-level rise. The measures taken to ensure water safety have been …
