For Coral Reef Restoration to Work, Remote Sensing Technology is Key

Technologies that can sense qualities like temperature, ocean color, and the shape of the seafloor from afar have transformed global marine monitoring by providing quick access to ocean data, including information from remote locations. Remote sensing technology is essential for successful coral reef restoration, argues a new study, and that it will only become more […]

Can Firefighting Strategies Save the Corals?

Coral reefs provide many ecosystem services, but are dying at an alarming rate due to stressors such as disease. Find out how scientists are beta-testing disease mitigation techniques derived from firefighting. Constance SartorI am a Master’s student at the University of Guam. My current research interests are coral transcriptomics, microbiome characterization, and spatial epidemiology. I […]

Citizen Science, Oh My!

To understand ecosystem level changes, it is important to monitor an ecosystem over a long period of time. However, long-term funding can be limited, especially during times of economic hardships. How do researchers carry out long-term ecological studies in place where sustained funding is unavailable? Read this article to get a glimpse into citizen science, […]

A Person (or Fish) on the Inside: Scientists Discover New Ally to Fight Coral Bleaching.

Our ocean continues to warm at a rate faster than anyone expected and coral reefs are facing an absolutely massive threat. Scientists are hard at work, attempting to solve the global crisis that is climate change-induced coral bleaching and death. But what if these scientists had someone on the inside to help? Rishya NarayananRishya is pursuing […]

Climate-driven events leave an imprint on corals in the Great Barrier Reef

Last year, it was reported that half of the Great Barrier Reef had just died after heat stress caused severe coral bleaching in 2016 and 2017 back-to-back. Now, researchers believe that the way to study coral loss going forward is to understand how one climate-driven disturbance relates to those that came before it. Nyla HusainI’m […]

Lost in the sound: coral planulae habitat selection affected by boat noise

It can be hard to cut through the noises that surround us and focus on the task in front of us, right? This may not just be a human problem. Noise pollution may be another way human activity is negatively affecting corals. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]

We need reefs. Can we make some?

Do artificial reefs work to promote biodiversity? Check out this summary of work from the Mediterranean Sea to find out more! Sandra SchleierHola mi nombre es Sandra Schleier. Soy graduada de la Universidad de Rhode Island con una Maestría enfocada en la restauración de corales en el Caribe. Actualmente soy la traductora del inglés al […]

The Coral Dilemma: Is Hybridization the Key?

Coral: a mineral, plant, and animal all in one (oh my!) Unfortunately, coral is in danger- and the many reefs which support a wide variety of organisms (including humans) are rapidly dying. Does interspecific hybridization hold the key to our coral dilemma? Rishya NarayananRishya is pursuing an M.S. in Environmental Science Communications and Media Advocacy at […]

Going viral: relationships between coral reef health and viruses

What organisms live in coral reefs? Corals (obviously), fish, snorkeling tourists…but some of the most important members we can’t even see with the naked eye, and some argue aren’t even alive! In this post we explore the role of viruses in coral reefs, and what we do – and don’t – know about coral-virus interactions. […]

Plastics increase disease risks for corals

You have probably heard about the troubles coral reefs are facing and about the detrimental effects of plastic pollution in our oceans. Now these two issues appear to be linked: corals are getting sick when they come in contact with plastic. Find out more here. Ashley MarranzinoI received my Master’s degree from the University of […]

Just Put on the Market: Ideal for Coral Reef Development

Scientists Identify Best Spots for Reef Restoration Coral reefs have been front and center in the news lately, as rising temperatures, increased acidity, and nutrient pollution cause mass bleaching events and scientists lament losses they say mark the “death” of coral reefs around the world. Conservation superstars have even weighed in on the issue; Suzuki, […]

Corals get their auras read

Corals, depending on dominant cover type, can influence the microbial community living in the surrounding water. Read on to find out more about the coral aura-biome. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from […]

I’m Gonna Soak Up the Sun: Sunscreen’s Impact on Coral Communities

Sunscreen prevents skin cancer but may also be linked to coral bleaching and harm to coral larvae. Read more to find out what scientists found in corals off the coast of Hong Kong when they sampled for common sunscreen UV protection chemicals. Victoria TreadawayI am a PhD candidate at the Graduate School of Oceanography at […]

Small MPAs: the new all-you-can-eat buffets?

Marine Protected Areas (MPAs) are a popular conservation tool and are in many situations very effective. Unfortunately, as with many plans, there may be some unintended consequences, as seen in the case of small MPAs in Fiji, where they appear to have attracted corallivorous crown-of-thorns sea stars (Acanthaster spp.). Find out more in today’s oceanbites! […]

Hard Coral or Macroalgae? Coral Reefs May Have Another Option

Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]

Ocean mapping on a budget

The seafloor is complex and mapping it is difficult because direct observations are hindered because it is underwater. Scientists have developed field methods and remote sensing methods to model the geomorphology of the seafloor but they are either limited spatially or by resolution. A newer method being applied to seafloor mapping is called Structure from […]

Giving Thanks for the Ocean: The gratitude of the writers

Today is the day after Thanksgiving, but I think the spirit of gratitude should live on. Many of the other writers wanted to share their gratitude for the ocean. Some waxed poetic, some pragmatic, but all spoke from a personal place. Yet the gratitude we feel for the ocean unifies all of us—not just the […]

Grunts and Gnathiids: One Fish’s Daily Migration to Escape Parasites?

Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized? Rebecca FlynnI am a graduate of the University of Notre Dame […]

Speed dating: how finding that special symbiosis saved some coral from climate change

Choosing the right symbiont might be a coral’s ticket to cheating global warming. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

How badly do coral reefs and sharks need each other?

Overfishing threatens the populations of reef sharks that act as the top of the food chain on coral reefs. Their presence keeps the ecosystem in balance and without them, the reefs themselves are at risk of being overtaken by algae and losing much of the diversity they support. But is the story really that simple? […]
