Seafloor life is in danger of running out of oxygen as the ocean warms, but this may actually help to mitigate climate change.
Sharks offer more to humans than just pretty toothy grins…check out this article to learn how sharks and other top predators may act to regulate carbon production in marine food webs, which may have implications for climate change dynamics.
We know that CO2 is being absorbed from the air by the ocean, but how can we measure how much of the carbon in the ocean comes from human activity? By examining carbon data in the Pacific Ocean, scientists show that the ratio of heavy to light carbon atoms in the water can help answer this question.
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.
Bacteria in coastal waters can eat methane, a greenhouse gas – but just how much and how fast can they eat?
Most marine organisms require dissolved oxygen to sustain their survival. So what is the current status of oceanic oxygen levels? Read on to learn about the oft under appreciated resource of our planet!
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change!
Have that one relative who always argues that current climate change symptoms are part of natural variability? Check out this article and be prepared with some nifty statistics next time they try to make that claim!
Article: Reynolds LK, DuBois K, Abbott JM, Williams SL, Stachowicz JJ (2016) Response of a Habitat-Forming Marine Plant to a Simulated Warming Event Is Delayed, Genotype Specific, and Varies with Phenology. PLoS ONE 11(6): e0154532. doi:10.1371/journal.pone.0154532 Climate change is poised to dramatically alter the make-up and functioning of Earths’ ecosystems, including those in the oceans. […]
Young penguins living along the southwestern coast of Africa typically follow cool, nutrient rich water to find food as they grow up. This used to lead them to ‘delicious’ fish such as anchovies and sardines. However, in this ecosystem – the Benguela Upwelling Zone – climate change and overfishing have reduced these fish populations. This forces the young penguins to eat less nutritious fish so fewer of them survive to adulthood. This threatens the African penguin’s future. Conservation efforts are needed to ensure this important (and adorable!) species survives.
A team of researchers investigate why the ocean has been absorbing more carbon from the atmosphere in recent decades, and find ocean circulation could be responsible.
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory.

Within large timescales of glacial and interglacial periods, mini, rapid climate shifts may occur thanks to oceanic circulation processes and balancing global ocean budgets. The events in question originate in the North Atlantic; but, how do they affect the Antarctic?
Nitrous oxide is a powerful greenhouse gas made by environmental microbes. In the ocean, microbes making this greenhouse gas live in zones with little to no oxygen. Scientists always thought that Bacteria were making this gas. Recently, a team from the UK set out to explore this hypothesis in the Eastern Tropical Pacific, and found that actually a totally different type of microorganism, Archaea, were making the nitrous oxide. These are important findings since global warming and increased human inputs in the ocean are causing low oxygen zones to expand, potentially making even more greenhouse gas!
Sea ice levels in the Arctic Ocean safeguard thousands of marine biosystems. Protists are little known micro-organisms that play a key role in maintaining a balanced oceanic ecosystem. Read more to see how climate change is affected sea ice-levels, and what that means for our protist comrades.
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!
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.
