Rapid changes in the Southern Ocean threaten ecosystems

Rapid acidification of the Southern Ocean could occur in the next 30 years with potentially huge impacts to local ecosystems. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For my research I sometimes spend months […]

Wanderings through the Western Society of Naturalists

Takeaways and notes from Sacramento and a jam-packed Western Society of Naturalists meeting! Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. Sarah Gilman, measuring and modeling energy budgets in intertidal species. I am a climate scientist and marine community ecologist and my […]

Diversity and its role in combating the effects of climate change

In the battle against climate change, ecosystems need to get down with diversity. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. Sarah Gilman, measuring and modeling energy budgets in intertidal species. I am a climate scientist and marine community ecologist and my […]

How a whole reef community’s response to OA is impacted by the individual responses of different players

Researchers from California used a unique ex situ experiment to monitor two near identical reef communities in different concentrations of dissolved carbon dioxide to observe the unique responses of community members and their roles in the whole community response. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who […]

Decalcifying Calcidiscus: An effect of ocean acidification on plankton

The vastness of the ocean can be deceptive–you’d think that only big things would have an impact on something the size of an ocean. That’s not always the case, though. Sometimes the smallest organisms can influence huge, global processes. But one such small organism is faced with harsher conditions these days and isn’t faring too […]

Ocean acidification may make “peekaboo” harder for shrimp

What happens to a shrimp’s shell when exposed to more acidic conditions? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum of Natural History in Ocean Education. I am interested in […]

Giant Clams Catch a Giant Break

Most of today’s research into the effects of climate change and ocean acidification is all doom and gloom: this animal and that ecosystem are developmentally challenged as a result of warming temperatures and lowered pH. This new study out of Australia is a rare bit of good news in the field, finding that giant clams […]

Path of Corrosion: How Scientists Modeled Ancient Sea-Floor Acidity

Today, we see a rapid release of CO2 to the atmosphere associated with climate change. The same was true 55 million years ago during the PETM, a time when – sediment records show – there was pervasive carbonate dissolution along the sea floor. But it was not the same pattern everywhere. Scientists attempt to model […]

Consummate Corals: resilience in an acidifying ocean

Gloom and doom has been the dominant message associated with climate change. However, it is important to remember that when faced with change, not all species and ecosystems are created equal. Recently, researchers have found that several species of cold-water corals are quite resilient to ocean acidification. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am […]

Sea urchins work harder, faster to cope with ocean acidification

The ability of sea urchins to withstand ocean acidification comes at a hidden cost. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

Highlights from the National Shellfisheries Meeting

Ever wanted to know what it’s like to go to a scientific conference? Here’s a summary of what conferences are all about, plus the four most interesting talks I saw at this year’s National Shellfisheries Association meeting. Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and […]

Coral Reef Restoration Through Human-Assisted Evolution

Coral reefs populations are declining. Is it possible that we could help restore coral reefs by speeding up their evolutionary processes? Researchers propose new management strategies for aiding reef restoration by accelerating the natural processes of evolution. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology […]

Like father, like son? Is survival under ocean acidification heritable?

Can marine life adapt to ocean acidification? Well, first we need to understand if these favourable characteristics (survival under elevated CO2 conditions) are genetically determined and can be passed on to the offspring! Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the […]

Macrobioerosion rates and what they mean for reefs

Today macrobioerosion is a good thing that provides cement for the foundation of reef systems. So more macrobioerosion could mean more reefs, right? No! Perhaps too much of a good thing could have dire consequences for the future of the calcium carbonate budget. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a […]

Damselfish in distress: on ocean acidification and suicidal reef fish

Fish are rebelling. What’s the cause? Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
