Guest post by Mark Schick, collections manager, Shedd Aquarium There was grim news for the world’s coral reefs this October, when the National Oceanic and Atmospheric Administration (NOAA) declared the third global coral bleaching in history. This event signifies major changes in oceanic living conditions and temperatures, some of which are brought upon by our…
Comparing a bleached anemone to the undead may be a bit of a stretch, but it is fair to say a bleached anemone is hovering somewhere between life and death and depending on what happens next, it can go either way. We got a closer look at the phenomenon of bleached anemones earlier this year…
Researchers announced this month that a massive global coral bleaching event is jeopardizing the health of coral reefs around the world, and the crisis is still heating up. A triple threat of climate change, El Niño and a climate change-induced “warm blob” in the Pacific is causing the ocean to reach unusually high temperatures, stressing…
The coral reefs of Palau hold approximately 400 species of hard corals, 300 species of soft corals, and 1400 species of reef fish. Palau is internationally renown for its beautiful landscapes and seascapes as well as its biological significance to the environment. The Khaled bin Sultan Living Oceans Foundation undertook its third expedition with the International League of Conservation Photographers in this fabled archipelago, working with iLCP Fellow Keith Ellenbogen.

Protected areas are a hallmark strategy in marine conservation. Yet when they were first created, a growing lethal threat had not yet fully revealed itself. Warming, acidifying, and rising seas have devastated the world’s sensitive coral reefs, widely regarded as “ground zero” for climate change. El Niños and marine heat waves can bleach and destroy vast areas of healthy, biodiverse reefs even where they occur within “protected” parks. If the global impacts of climate change do not stop at park boundaries, what can scientists do? One strategy is to identify and protect climate refuges – habitats with more stable environments where species can survive warming temperatures.
The Khaled bin Sultan Living Oceans Foundation conducts scientific surveys on coral reefs around the world to determine the health and resilience of the reef. The primary scientific goals of the Expeditions are to map and characterize coral reef ecosystems, identify their current status and major threats, and examine factors that enhance their ability to resist, survive and recover from major disturbance events like bleaching, cyclone damage, or Crown of Thorns outbreaks. iLCP Fellow Jürgen Freund documents an expedition to the magnificent Great Barrier Reef.
With corals across the globe bleaching due to advancing ocean temperatures, many of the world’s coral reef experts believe these centers of marine biodiversity may become the first casualty of climate change. But while the news on corals has been largely grim, it is not beyond hope.
