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.
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.
