Ocean Acidification
More Intense Summer to Winter Swings in Oceanic Dissolved CO2
Ocean CO2 levels vary depending on the time of year. Landschützer and his colleagues are the first to show that human-emitted CO2 is making these seasonal swings more severe, potentially to the detriment of many marine organisms. Julia DohnerJulia is a second-year PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus […]
Ocean Acidification: No Longer Confined to the Sea Surface
Acidification, one of the highest-visibility impacts of human activity on the ocean, was thought to be confined to its upper layers. Chen and his colleagues show that’s no longer the case. Julia DohnerJulia is a second-year PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on chemical oceanography, which often […]
Wandering copepods can’t find their way home in acidic oceans
Journal source: Smith, J. N., C. Richter, K. Fabricius, and A. Cornils. 2017. Pontellid copepods affected by ocean acidification: A field study at natural CO2 seeps. PLoS ONE 12 doi: https://doi.org/10.1371/journal.pone.0175663. Introduction Ocean acidification (OA for short) is a topic that seems to be receiving increased attention, and if you’ve scrolled through some recent Oceanbites posts, […]
It’s Getting Hot In Here: How Ocean Acidification and Warming Affect Shark Hunting and Behavior
Elasmobranchs such as sharks and rays face physiological and behavioral changes due to ocean acidification and rising ocean temperatures. Read about how these changes influence how sharks hunt and their role in the marine ecosystem. Aditi TripathyHello! I am an undergraduate student majoring in Marine Biology and with a minor in Acoustics at the University […]
Stressed-out microbes in an acidifying ocean
The ocean is acidifying in response to carbon dioxide emissions, but we are just beginning to learn how this effects the ocean’s most abundant lifeforms – microbes. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in […]
Small but mighty: Will the epaulette shark survive ocean acidification?
Check out the first installation of Sharkbites Saturday! The epaulette shark is a small egg-laying species native to Australia. In this study, scientists look at the effects that increased carbon dioxide from climate change may have on these interesting reef dwellers. Carolyn WheelerI am currently a PhD student studying marine science at the University of […]
Ocean acidification makes predators dumb
Chemistry is important for a lot of things, but can it change the behavior of animals? Read on to find out how changes in water chemistry alter the behavior of a venomous cone snail! Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and how they respond […]
What Does the US Election Mean for Our Oceans?
The oceans are subject to the whims of national policy, and yet they know no borders. Being poor ocean stewards here in the US could cause serious problems all over the world, as well as affecting the smidgeon of blue we can see from our shores. In this post, I outline a few ideas about […]
Can being sick be a good thing for surviving ocean acidification?
Scientists (myself included!) have been doing a lot of work on how marine animals respond to rising carbon dioxide (CO2) levels, but CO2 alone isn’t the only problem. This study looks at how having a parasite affects survival in marine snails exposed to high CO2 – do they survive longer in those conditions with or […]
Ocean Acidification Disrupts Yellowfin Tuna Development
We’ve heard a lot about ocean acidification and how it negatively impacts calcified organisms like corals or shellfish. But did you know that acidification also has wide-ranging impacts on other marine species? Researchers recently found lethal and sublethal effects of acidification on yellowfin tuna. Dina NavonI am a doctoral candidate in the Organismic and Evolutionary […]
Larval Donkey’s ear abalone threatened by climate change
Abalone are an economically and culturally important group of edible sea snails, and a new study demonstrates that they’re at serious risk of decline due to ocean acidification. Dina NavonI am a doctoral candidate in the Organismic and Evolutionary Biology program at the University of Massachusetts Amherst. I’m interested in how an individual’s genes and […]
Disoriented fish are getting lost at sea!
Young fish rely on sound cues to navigate the vast ocean, but as our oceans acidify, the journey home to safely settle becomes much more difficult. Disoriented and slow, these fish are getting lost at sea Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and transplant […]
Are marine “nuisance” species expected to increase under ocean acidification?
Most studies that look at how animals respond to climate change look at species we like – oysters, corals, and whales are just a few examples. The authors of this review looked at something else – how are the species we hate going to respond to climate change, specifically ocean acidification? Read on to find […]
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 […]
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 an earth scientist (geology and […]
Tiny lobsters, big problems.
Larval lobsters face potentially dangerous situations, find out how they fare against a couple important environmental stressors (salinity and pH changes). Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in the Gulf of Mexico. When not […]
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 […]
Can sperm cells make it in an acidified ocean?
Researchers in Australia investigated whether sea urchin sperm are going to make it through an acidified ocean or if they’ve reached their tipping point. Read on to learn more! Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and how they respond metabolically to ocean acidification projections. […]
