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!
Like frogs, sea snakes can uptake oxygen through both their lungs and their skin. How will these “bimodal breathers” cope with warm ocean temperatures?
Research in marine renewable energy and climate systems will grow ever more important in the future. The research for these areas are not just done on the coast, however – I ventured into the mountains to learn more.
Seabirds are switching up their annual winter travels in response to climate change…read on to discover how researchers used museum displays, isotopes, and really expensive GPS tags to piece together this seabird story.
Long before the Vikings reached North America, a group of coastal spiders was already sailing around the world using prevailing winds, currents, and rafts.
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 .
New analysis of 100 years of sea level measurements from tide gauges show that we might be underestimating the global rate of sea level rise.
Scientists have been doing a lot of work recently trying to figure out how species are going to react to climate change. This research group wanted to figure out just how much heat seahorses could take…and seeing as they can’t get out of the ocean, things aren’t looking good. Read on!
Tropical Cyclones in the western Pacific Ocean have been intensifying in recent decades, but different data sets and methodologies made it hard to create accurate comparisons and models. Researchers adjusted these data sets to find that cyclones that make landfall are intensifying at faster rates than those that stay in the open ocean, and that the intensification is tied to rising ocean temperature.
The Southern Ocean has been getting less salty for decades, and scientists have finally proved that sea-ice is responsible for the extra fresh water in the ocean.
Coccolithophores stand out from other marine phytoplankton in their ability to form calcified plates. Why is it beneficial for coccolithophores to calcify and how may these plates hold up under future ocean conditions?
Everyone knows that polar bears have become the poster children for species threatened by climate change. And it’s for good reason that they are. Polar bears rely on sea ice for access to prey, finding mates, and creating dens. The persistence of the species depends on the state of sea-ice and more generally a healthy marine ecosystem in the Arctic. Unfortunately, the volume and extent of sea ice have been decreasing by 28% and 14% per decade. Is there a way for polar bears to adapt to the changing sea ice coverage in this sensitive habitat?
Paper: Claus W. Böning, et al. 2016. Emerging impact of Greenland meltwater on deepwater formation in the North Atlantic Ocean. Nature Geoscience, v.9: 523–527. We know the ocean is warming due to climate change. But did you also know there are huge paths that heat and energy takes through the global ocean? Although the ocean […]
Scientists investigate warm water that drives melting in Antarctica with the help of some seals with high-tech hats.
Coral reef fish are some of the most sensitive animals to climate change. How will coral reef fish respond to predicted increases in temperature and carbon dioxide? Do they have the ability to adapt to future conditions or is it already too late?
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.
Species invasions have become serious issues in the marine environment, mostly as a result of increased ship traffic. Once a new species invades an area, it is next to impossible to draw it out. What if there was a way to predict the arrival of alien species to new locations in the ocean? Would this predictive power help minimize future invasions?

While icebergs are calving from Antarctic glaciers at alarming rates, they may provide a negative feedback for the carbon cycle. Giant icebergs bring large amounts of iron to iron-poor areas of the Southern Ocean, stimulating primary productivity and boosting carbon sequestration.
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.
