It’s been shown that the surface of the South Pacific Ocean has been warming by absorbing excess heat from the atmosphere, but is this heat making it down to the deep ocean? Deep-ocean warming can lead to more rapid global warming in the future, but detecting it is tricky. Despite the challenges, a team of researchers shows that the Deep South Pacific has indeed been warming.
You may not have to go to Hogwarts to find an invisibility cloak of your own. Although, the trip to this extreme environment full of transparent crustaceans may be just as tricky to get to. Read more to find out how hyperiid amphipods are able to make themselves invisible!
While not as exciting as the new era of peace predicted by 5th Dimension, it is pretty cool that scientists can measure ocean chemistry from space. The marvels of modern technology, amiright?
Seagrasses are one of humans’ greatest sidekicks. They are nursery areas for many species including commercially important ones, they protect coastal communities from extreme weather, they absorb carbon dioxide and release oxygen via photosynthesis and much more. Now, research shows that seagrasses can also reduce rates of disease in humans, fishes and invertebrates such as corals. Read more to find out how!

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!
Climate change affects ecosystems worldwide, but how do conservationists decide which of planet earth’s ecosystems are most in need?
This St. Patrick’s Day, think outside the green beer and whiskey and try an ocean-inspired beer! Didn’t know there were beers brewed with ocean life? Read on to learn more about how our oceans and your beer are intertwined.
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!
Methane is an important, and often forgotten, greenhouse gas. It comes from a variety of sources including wetlands, rice paddies, and natural gas operations. This article explores methane’s role in our changing climate and investigates some natural and anthropogenic sources.

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.

Because of their ability to conduct photosynthesis, most of our planet’s oxygen comes from microscopic organisms in the ocean called algae. In addition to photosynthesis, some of these algae can also hunt and consume prey to supplement their energy needs. In this study a group of scientists has set out to determine just how their hunting strategy works, and why each strategy has its own set benefits and drawbacks.
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.

New discoveries are made every day, but ‘new’ does not always mean current. In this case, scientists are using technology to reconstruct the jaws of a creature that dominated the oceans over 70 million years ago and are solving the mystery of how its strange teeth allowed for a diverse diet. Intrigued?
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?
It might seem like a no-brainer to ban shark fishing as well as the sale and trade of shark products. But scientists wonder: is there a more effective management strategy? Read more to find out!
