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 how America’s new political landscape might affect ocean science and the future health of our global oceans .
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 without a bunch of parasites? Read on for a surprising answer!
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.
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.
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
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 out!
Rapid acidification of the Southern Ocean could occur in the next 30 years with potentially huge impacts to local ecosystems.
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.
Larval lobsters face potentially dangerous situations, find out how they fare against a couple important environmental stressors (salinity and pH changes).
What happens to a shrimp’s shell when exposed to more acidic conditions? Read more to find out!
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 (important economically for food and tourism) might escape the worst effects of ocean acidification thanks to their symbiotic bacteria.
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 these spatial varieties and explain what occurred.
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!
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!
Researchers from the University of Gothenburg in Sweden found that ocean acidification may cause hyperactivity in catfish sharks.
As a novelist writing about oceanography, I spend a decent amount of time parsing scientific studies. Over the past several years my vocabulary has expanded to include terms like band saturation, turbidity currents, and foraminifera—phrases and words that had not existed in my wildest dreams when I first started writing. I’ve relied on studies and […]
How will increased atmospheric carbon dioxide affect your dinner? Larval dolphinfish (or, ‘mahi mahi’) are apparently very sensitive to increased ocean acidification, a product of rising atmospheric CO2. This is one of the first studies of the effects of ocean acidification on the early life stage of a pelagic fish species.
Some catfish aren’t just limited to the traditional five senses – instead, they have a unique adaptation to sense pH changes in the water to help them find their prey.
From the very first sentence of the abstract, these scientists make clear they are not messing around, “Ocean acidification is a result of the uptake of anthropogenic CO2 from the atmosphere into the ocean and has been identified as a major environmental and economic threat.” In other words, humans are causing ocean acidification and the consequences will hit everything from the blue of the sea to the green in our wallets. So how is the most abundant species of calcifying phytoplankton being affected?
Has the pH of our oceans decreased significantly? Lauvset and Gruber say yes, for the North Atlantic Subpolar Gyre.
